Owners Manual
Thank you for your purchase of an Signaworks® product. We take pride in the equipment we build, and we appreciate your support. We will do everything we can to keep you happy with your purchase for many years to come. Please review this manual carefully, and if you have any questions, call, e-mail, or fax us and we will be glad to help you. Signaworks support can be reached at:
The Production Pace Timer (PPT) is a special purpose numeric marquee designed to pace the production rate of any manual process. Each line of the marquee is a four-digit counter constructed from 2.3” LED display modules providing visibility up to 115 feet.
The GOAL line automatically counts at a user programmable time interval indicating how many units of production are expected. The ACTUAL line of the marquee counts in response to an input, compatible with most photo-eyes, whisker switches, and palm switches, indicating how many units of production have actually been completed. Four count logic inputs are provided allowing the PPT to monitor multi-lane production lines with up to four lanes. For applications where bad parts need to be subtracted from the running actual count, the fourth count input can be configured to decrement the actual counter instead of incrementing it.
Scaling factors can be independently programmed for the GOAL and ACTUAL counters, allowing GOAL and ACTUAL to increment by any arbitrary amount between 1 and 9999. A typical application of the scaling feature is to make the PPT display total units scheduled and actually produced, even though the count input is activated by a sensor that detects cases / pallets / bundles of finished product. Alternatively for applications where it takes multiple machine cycles to complete a singe unit of production, the interpretation of the scaling factors can be change from the usual n units of production per count pulse (whole count scaling), to n count pulses per unit of production (fractional count scaling).
The GOAL and ACTUAL counters may be independently reset. Reset inputs are provided for connection to a controlling device, or the operator may reset either counter via the front panel keypad.
The GOAL timer may be paused to stop the GOAL counter from automatically incrementing during breaks. A HOLD input is provided for connection to a

controlling device, or the operator may hold the GOAL timer via the front panel keypad.
A 1 Farad Super-Cap backs up the PPT’s memory. The Super-Cap allows the PPT to retain operational values for five days without power. Unlike batteries, Super-Caps do not require special recharge circuitry and have an expected life span in excess of 10 years.
An RS-232 / RS-485 capable serial port allows the PPT to drive “slave” marquees or can be configured to interface the PPT to a central computer system. All of the PPT’s registers can be read or written via the serial interface. When the PPT is being controlled via the serial interface, the front panel keypad may be disabled to prevent operator modification of PPT registers.
The PPT is enclosed in a NEMA-1 black satin painted 16-gauge steel enclosure with a 1/8” thick, acrylic display lens. The enclosure is designed to be mounted to a wall by four holes in the back of the enclosure.
Internal screw terminals are provided to connect: 120VAC power; serial communications; HOLD, T-RST, B-RST, and (4) CNT logic inputs.
An optional red / green stack light can be factory installed at the customers request. The stack light can be configured to illuminate green when production output is within programmed tolerances, or illuminate red / flashing red when production output falls outside programmed tolerances.
Every PPT is carefully tested, both mechanically and electrically, before shipment. Inspect the marquee for damage, which may have occurred in transit. If there is evidence of damage, file a claim with the shipper and notify Signaworks.® Save the shipping materials for inspection.
If there are no signs of damage, carefully remove the PPT from the shipping carton. Then mount, hang, or set the PPT in a location where the unit is readily visible.

The PPT is designed to be mounted to a wall by four screw holes in the back of the enclosure. When choosing the location to mount the PPT, keep in mind the operator will need access to the keypad on the front of the unit.
Mounting Holes
Mounting Holes
The PPT should be moved to its operating position and mounted to the wall using the four holes in the back of the enclosure. A drawing of the box portion of the enclosure is shown below.

Most of the electrical connections to the PPT are available on both a customer connector, and a factory connector. Customer connectors provide simple screw terminal termination for 22 to 16 gage wires for use by the customer. Factory connectors provide crimped pin termination for 20 gage wires. The primary purpose of the factory connectors is to provide Signaworks with an alternate location to terminate factory installed wiring that will not consume customer screw terminals.
Indicator lamps provide real time feedback on the status of the PPT to aid debugging problems. The power indicator lamp illuminates when power is applied to the PPT. The TXD, RXD, and ENB lights blink during serial communications, and the remaining lamps illuminate when the associated logic input is activated.
Dip switch blocks provide a way to configure several basic PPT options. Most of the switches are used to configure the PPT serial port. Other miscellaneous settings include leading zero blanking, timebase selection, and count input options.

The PPT requires 120VAC at ½ Amp current draw to operate (optional stack light included). However, If custom devices are connected to the silicon relay outputs, the maximum current draw could be as high as 1½ Amps. The PPT can operate from either 60Hz or 50Hz power.
If your unit was purchased with the power cord option, the factory will have already installed an industry standard three prong line cord, and connected it to the factory 120VAC power connector. If this is the case, do not connect any wires to the customer 120VAC power connector.

Optional Logic Input Extension Cable Pinout
If your PPT was purchased with the optional logic input extension cable, the factory will have already installed wiring that provides the CNT-1 and HOLD inputs on a six foot extension cable terminated in a four pin Molex Minifit Jr connector as diagrammed to the right.
Even if the logic input extension cable is installed, it is still permissible to use the customer logic input connector to connect other devices to the PPT. The CNT-1 wire of the extension cable is connected in parallel with the CNT-1 screw terminal on the customer logic input connector.

The PPT provides two 120VAC silicon relay outputs or two DC Sink (NPN) relay outputs. These connectors are not intended to be used by the customer. They are used by ALI to control various optional PPT add ons, such as the red / green stack light.
When the PPT is ordered with the optional red / green stack light, the Ha 120VAC relay output controls the red light, and the Hb 120VAC relay output controls the green light.
The DC Sink relay outputs are reserved by ALI for future feature expansions to the PPT.
Note: Do not connect any wiring to the 120VAC or DC Sink relay output connectors unless directed to do so by Signaworks Inc.

The PPT has several indicator lamps that are quite helpful for debugging wiring problems. Apply 120VAC power to the PPT and then make sure the PWR indicator is illuminated. If it does not, then the 120VAC power wiring is probably incorrect.
Activate inputs while observing the LED2 / LED3 indicator lamps. The indicator corresponding to the activated input should illuminate. If it does not, try activating the input with a few inches of wire.
Observe the ENB, TXD, and RXD lamps while attempting to communicate with the PPT. The RXD lamp should illuminate if the PPT is receiving commands. The TXD lamp should illuminate when the PPT is responding.

The configuration dip switch blocks are used to configure semi-permanent PPT settings such as baud rate, address, leading zero blanking, and timebase selection. These are settings that are likely to be decided upon when the PPT is first installed, and then never changed. PPT settings that are likely to change from week to week are set using the keypad on the front of the unit.

If your PPT was ordered with the optional American 120VAC line cord option, you will simply need to provide a standard 120VAC duplex near the PPT. However if your unit does not have the optional line cord, you will need to connect 120VAC power to screw terminals inside the PPT as shown below.
Connect the power wiring to the customer 120VAC power screw terminal connector on the PPT circuit board. Power wires should be American Wire Gauge #16 with a 600 volt insulation rating. The PPT requires 120VAC power at less than ½ Amp of current. However, if custom equipment is connected to the 120VAC output relays, the PPT power draw can be as great as 1 ½ Amps. Both 60Hz and 50Hz line frequencies are acceptable.
Typical Power Wiring

Owners Manual
If your PPT was ordered with the optional count push button kit, or the optional photo-eye kit, some / all of the logic wiring you need may have already been completed by the factory. However you may still wish to review this section for information on how the PPT logic inputs are operated.
The PPT’s logic inputs are designed to be activated by connecting an input screw terminal (HOLD, T-RST,B-RST, or CNT) to a ground screw terminal (GND). Typically this is accomplished with a push button switch, whisker switch, or mechanical relay contact. However it can also be done with an NPN or CURRENT SINKING photo-eye, proximity sensor, or solid state relay.

The digital logic inputs are sampled once every 10mS, and then processed by a simple software debounce algorithm. Transient conditions lasting less than 30mS are rejected as noise. Due to this filtering, the maximum allowed count rate is 10Hz, with a 50% duty cycle waveform (50mS On Time, 50mS Off Time), and the minimum width of a reset pulse is 50mS.
Optional Logic Input Extension Cable Pinout
If your PPT was purchased with the optional logic input extension cable, the factory will have already installed wiring that provides the CNT-1 and HOLD inputs on a six foot extension cable terminated in a four pin Molex Minifit Jr connector as diagrammed below.
Even if the logic input extension cable is installed, it is still permissible to use the customer logic input connector to connect other
devices to the PPT. The CNT-1 wire of the extension cable is connected in parallel with the CNT-1 screw terminal on the customer logic input connector.

If you are using a 12VDC photo-eye or proximity sensor, the PPT can supply up to ½ amp of power to the sensor. Be careful when connecting the +12VDC output to your sensor. If the sensor draws too much current, the fuse (F1) soldered to the PPT board will blow to protect the PPT power supply.
Example logic input wiring is shown in the diagram below. You may chose to not use some of the logic inputs. The minimum requirement is one switch or sensor that is used to activate one of the count inputs each time a unit of production is completed. All of the other inputs (HOLD, T-RST, B-RST) functionality can be replicated by pressing buttons on the PPT keypad.

Use of the PPT’s RS-232 / RS-485 serial port is an optional advanced feature. Some installations will not use the serial port, rendering serial port wiring and configuration unnecessary.
If use of the serial port is desired, it is still advisable to first complete and test a basic installation, and then add use of the serial port later. For this reason, wiring and configuration of the serial port is covered in the manual sections that discuss operation of the PPT serial port instead of the installation sections.
The PPT serial port can be configured to automatically transmit data to slave marquees once per second. This is the “MASTER” mode of operation. For more information about using the PPT as a MASTER or a SLAVE marquee, including suggested wiring and configuration see section 3.1 of this manual.

The PPT serial port can be configured to accept commands from a central computer system. This is the “COMMAND” mode of operation. In this mode, a central computer system can issue commands to the PPT to read and write registers. For more information about using the PPT in COMMAND mode, including suggested wiring and configuration see section 3.2 of this manual.

For a basic PPT installation, only the miscellaneous options selected on dip switch SW2 switches 4, 5, 7 and 8 has any effect. Switch 4 enables leading zero blanking, switch 5 selects the time base, switch 7 sets the fourth count input direction, and switch eight selects whole or fractional count scaling. All of the other dip switch settings can be ignored until the PPT serial port is used because they have no effect on the basic operation of the PPT. Dip switch settings that effect the serial port are covered in the manual sections explaining how to use the PPT serial port.
The PPT can be configured to display data with leading zeros blanked, or non- blanked. When leading zero blanking is enabled, the PPT will display a count of one as “ 1”. With leading zero blanking disabled, the PPT will display a count of one as “0001”. To enable leading zero blanking, turn dip switch SW2 switch 4 ON. To disable leading zero blanking, turn dip switch SW2 switch 4 OFF

The GOAL counter of the PPT automatically increments at a user configurable time interval known as PACE time. This time interval can be specified in whole seconds, or in 1/10th of seconds. The unit of time the PPT uses for the PACE setting is known as the time base. When a 1 second time base is selected, pace may range from 1 to 9999 seconds. When a 0.1 second time base is selected, pace may range from 0.1 to 999.9 seconds. To configure the PPT for a 1 second time base, turn dip switch SW2 switch 5 ON. To configure the PPT for a 1/10 th second time base, turn dip switch SW2 switch 5 OFF.
The PPT has four CNT logic inputs. The CNT-4 input typically increments the ACTUAL counter just like the other three CNT inputs. However, the CNT-4 input can be configured to decrement the ACTUAL counter instead. To configure the CNT-4 input to decrement the actual counter, turn dip switch SW2 switch 7 ON. To configure the CNT-4 input to increment the actual counter, turn dip switch SW2 switch 7 OFF.
Whole or Fractional Count Scaling
The PPT can be configured for whole or fractional count scaling. The selection effects both the goal and actual counters.
Whole count scaling is required in applications where more than one finished product is completed each time the PPT receives a count pulse. Typically this occurs in situations where the PPT count input is connected to a sensor that detects boxes, cases, or pallets of finished product, and each box, case, or pallet contains more than one finished product. For example, If whole count scaling is selected, and the ACTUAL-SCALE (ASCL) register is set to three, then each time the count input is pulsed the ACTUAL counter will increment by three.
Fractional count scaling is required in applications where the PPT will receive more than one count pulse for each finished product. Typically this occurs in situations where the PPT count input is connected to a sensor that detects machine cycles, and it takes more than one cycle to complete each finished product. For example, if fractional count scaling is selected, and the ACTUAL- SCALE (ASCL) register is set to three, then the ACTUAL counter will increment by one for every three count pulses.
In the simple case where the PPT receives one count pulse for each finished product, select whole count scaling and set the ACTUAL-SCALE (ASCL) register and GOAL-SCALE (GSCL) register to one.
Page 17
The Production Pace Timer Owners Manual
To select fractional count scaling, turn dip switch SW2, switch 8 ON. To select whole count scaling, turn dip switch SW2, switch 8 OFF.
The PPT keypad is designed for operation by a human finger, and when properly used, each key is rated for over 1,000,000 operations. However, if a hard object, such as a pen, pencil, or wood / steel rod is used to operate the keypad, it will severely decrease its operational lifespan. We have observed keypads failing in as little as three months when abused. Keypad failures due to abuse are not covered under the 1 year warranty.
The photo below shows the typical damage cased by using a hard object such as a pencil to depress the [RUN] key. The polycarbonate overlay has warn through exposing the 12oz tri-dome. Additionally the tri-dome has collapsed, causing the key to “stick on”. When this happens, all of the keys on the keypad become non- functional. To repair the PPT, the keypad must be pealed off of the PPT front panel and replaced.
Replacement keypads may be purchased and shipped to your factory for you to install. Contact Signaworks and order part number, KB-2659-003 which has a list price of $25 each.

When the PPT powers up, it first restores GOAL, ACTUAL, and other register values from backed up memory. If the PPT’s backed up memory has expired then all PPT registers are reset to default values. Every PPT is operated at the factory for 24 hours before shipping the unit to the customer. Therefore it is very likely that when the PPT starts up, the GOAL and ACTUAL values that were on the PPT when it was packed at the factory will be restored.
The rightmost decimal point of the GOAL counter flashes when the GOAL timer is running. The rightmost decimal point of the ACTUAL counter lights when the COUNT input is asserted.
The GOAL 1’s digit decimal point flashes when the GOAL counter is running.
The ACTUAL 1’s digit decimal point illuminates when the COUNT input is activated.
The [TOP] button on the keypad resets the GOAL counter. The [BOT] button resets the ACTUAL counter. The [HOLD] button pauses the GOAL counter. The [RUN] button cancels the operator request to pause the GOAL counter.
The [F1], [+], and [F4] buttons are used to adjust PPT registers, which is covered in the next section.

The PPT has several registers that can be adjusted from the operator keypad on the front panel. The following registers can be accessed and adjusted from the PPT operator keypad by pressing the [F1] key on the PPT keypad.
Register Name | Register Function |
PACE
| The PACE register holds the number of seconds to wait between GOAL counter increments. Set PACE to 5 seconds, to instruct the GOAL counter to automatically increment once every five seconds. If the PPT time base is set to 1 second, PACE may be set to any value ranging from 0001 to 9999. 5 seconds is entered as 0005. If the PPT time base is set to 1/10th second, PACE may be set to any value ranging from 000.1 to999.9. 5 seconds is entered as 005.0. |
ACTUAL-SCALE
| The ACTUAL-SCALE (ASCL) register holds the scaling factor for the ACTUAL counter. Each time any CNT logic input is activated, the ACTUAL counter is incremented by the ACTUAL-SCALE (ASCL) setting. ACTUAL-SCALE (ASCL) can be set to any value ranging from 0001 to 9999. To make the ACTUAL counter increment by 7 each time any count logic input is activated, select whole scaling by turning SW2 switch 8 OFF, and set the ACTUAL-SCALE (ASCL) register to 0007. To make the ACTUAL counter increment by 1 each time any CNT logic input is activated three times, select fractional count scaling by turning SW2 switch 8 ON, and set the ACTUAL-SCALE (ASCL) register to 0003. |
GOAL-SCALE
| The GOAL-SCALE (GSCL) register holds the scaling factor for the GOAL counter. Each time the GOAL pace time timer runs out (see PACE register above) the GOAL counter is incremented by the GOAL-SCALE (GSCL) setting. GOAL-SCALE (GSCL) can be set to any value ranging from 0001 to 9999. To make the GOAL counter increment by 12 each time the GOAL pace time timer runs out, select whole count scaling by turning SW2 switch 8 OFF, and set GOAL-SCALE (GSCL) to 0012. To make the GOAL counter increment by 1 for every fourth time the GOAL pace time timer runs out, select fractional count scaling by turning SW2 switch 8 ON, and set the GOAL-SCALE (GSCL) register to 0004. |

Register Name | Register Function |
ACTUAL
| The ACTUAL (ACUL) register holds the actual counter value. The only reason to modify this register is to manually correct an error in the actual count. ACTUAL (ACUL) can be set to any value ranging from 0000 to 9999. |
GOAL
| The GOAL register holds the goal counter value. The only reason to modify this register is to manually correct an error in the goal count. GOAL can be set to any value ranging from 0000 to 9999. |
HIGH-HIGH
| The HIGH-HIGH (HIHI) register holds the very high efficiency trip percentage. This register only has an effect if your PPT has the optional red / green stack light installed. HIGH-HIGH (HIHI) can be set to any value ranging from 000.0% to 999.9% If production efficiency exceeds the HIGH-HIGH (HIHI) trip percentage, the PPT will flash the red stack light. The HIGH-HIGH (HIHI) trip point can be disabled by setting the register to 000.0%. |
HIGH
| The HIGH (HI) register holds the high efficiency trip percentage. This register only has an effect if your PPT has the optional red / green stack light installed. HIGH (HI) can be set to any value ranging from 000.0% to 999.9% If production efficiency exceeds the HIGH (HI) trip percentage, the PPT will illuminate the red stack light. The HIGH (HI) trip point can be disabled by setting the register to 000.0%. |
Page 21

Register Name | Register Function |
LOW
| The LOW (LO) register holds the low efficiency trip percentage. This register only has an effect if your PPT has the optional red / green stack light installed. LOW (LO) can be set to any value ranging from 000.0% to 999.9% If production efficiency drops below the LOW (LO) trip percentage, the PPT will illuminate the red stack light. The LOW (LO) trip point can be disabled by setting the register to 000.0%. |
LOW-LOW
| The LOW-LOW (LOLO) register holds the very low efficiency trip percentage. This register only has an effect if your PPT has the optional red / green stack light installed. LOW-LOW (LOLO) can be set to any value ranging from 000.0% to 999.9% If production efficiency drops below the LOW-LOW (LOLO) trip percentage, the PPT will flash the red stack light. The LOW-LOW (LOLO) trip point can be disabled by setting the register to 000.0%. |

The PPT computes a real time percent efficiency from the goal and actual counts. Efficiency values less than 100% mean that production is behind schedule. Efficiency values greater than 100% mean that production is ahead of schedule.
LOW-LOW, LOW, HIGH, and HIGH-HIGH efficiency trip points can be set to make the optional red / green stack light turn on / off when trip points are exceeded. If your PPT does not have the optional stack light installed, then you can skip this manual section and ignore the HIGH-HIGH, HIGH, LOW, and LWO- LOW register settings.
Normally the green light is turned on, and the red light is turned off. If the LOW or HIGH efficiency trip point is exceeded then the green light turns off, and the red light turns on. If the LOW-LOW or HIGH-HIGH efficiency trip point is exceeded, then the green light turns off, and the red light is flashed. A diagram of the trip points and resulting light conditions is shown below.

Widget Co. the worlds leading manufacturer of widgets wishes to pace the widget production process, so they purchase a PPT with the red / green stack light option. A whisker switch is installed on the production line to detect completed widgets and connected to one of the PPT CNT inputs. For the initial install, the HOLD, T-RST, and B-RST logic inputs will not be used, instead it will be the line supervisors responsibility to reset the PPT at the start of the day, and hold the PPT during breaks using the PPT keypad.
The Widget Co. factory runs one shift, from 6:30AM to 4:00PM each day. 1st break is from 8:30AM to 9:00AM, lunch break is from 11:00AM to 11:30AM, and 2nd break is from 1:30PM to 2:00PM. The factory must produce 7,200 widgets per day to meet demand. Management decides that if the rate of production drops below 6,000 widgets per day, the PPT should flash the red light. If the rate of widget production ever exceeds 9,000 widgets per day, the PPT should illuminate the red light.
In order to configure the PPT for the Widget Co. factory, first we need to compute how many seconds the factory works each day. Consulting the Widget Co. schedule we see that the factory works (4) two hour blocks: 6:30AM – 8:30AM; 9:00AM-11:00AM; 11:30AM-1:30PM; and 2:00PM-4:00PM for a total of 8 hours worked each day. Since there are 60 seconds in a minute, and 60 minutes in an hour, we can compute the time worked in seconds...
Seconds Worked = 60 Seconds * 60 Minutes * 8 Hours = 28,800 Seconds
Now that we know that the factory is scheduled to produce widgets 28,800 seconds per day, and that ideally the factory should produce 7,200 widgets in that time, we can compute the PPT PACE setting...
PACE = 28,8000 Seconds / 7200 Widgets = 4 Seconds per Widget
Next we need to compute the HIGH-HIGH, HIGH, LOW, and LOW-LOW efficiency trip points to control the optional red / green stack light.
If efficiency exceeds the HIGH-HIGH trip point, the stack light will illuminate flashing red. Management does not want the stack light to flash red during over production conditions, so we will set HIGH-HIGH to 0.0% to disable this feature.
If efficiency exceeds the HIGH trip point, the stack light will illuminate solid red. Management wants the stack light to illuminate solid red if the rate of production exceeds 9,000 widgets per day. From this we can compute the HIGH setting...
HIGH = (9,000 Widgets / 7,200 Widgets) * 100 = 125.0%
Page 25
The Production Pace Timer Owners Manual
If efficiency falls below the LOW trip point, the stack light will illuminate solid red. Management does not want the stack light to illuminate solid red during under production conditions, so we will set LOW to 0.0% to disable this feature.
If efficiency drops below the LOW-LOW trip point, the stack light will illuminate flashing red. Management wants the stack light to illuminate flashing red if the rate of production drops below 6,000 widgets per day. From this we can compute the LOW-LOW setting...
LOW-LOW = (6,000 Widgets / 7,200 Widgets) * 100 = 83.3%
To summarize, the PPT registers need to be set as follows: PACE = 004.0 (Increment GOAL every 4.0 seconds)
ACTUAL-SCALE = 0001 (ACTUAL counter increments by 1 each count pulse) GOAL-SCALE = 0001 (GOAL counter increments by 1 each PACE seconds) HIGH-HIGH = 000.0 (Disable very high efficiency trip point, flashing red) HIGH = 125.0 (Activate red light for efficiency > 125.0%)
LOW = 000.0 (Disable low efficiency trip point, solid red) LOW-LOW = 083.3 (Active flashing red light for efficiency < 83.3%)
To set the PACE register, press the [F1] key once to select the PACE register. Use the [+] keys to select a PACE of 004.0 seconds. Then press the [F4] key to apply the new PACE settings.
To set the ACTUAL-SCALE (ASCL) register, press the [F1] key twice to select the ACTUAL-SCALE (ASCL)register. Use the [+] keys to select a scale factor of 0001 units. Then press the [F4] key to apply the new ACTUAL-SCALE (ASCL) setting.
To set the GOAL-SCALE (GSCL) register, press the [F1] key three times to select the GOAL-SCALE (GSCL) register. Use the [+] keys to select a scale factor of 0001 units. Then press the [F4] key to apply the new GOAL-SCALE (GSCL) setting.
To set the HIGH-HIGH (HIHI) register, press the [F1] key six times to select the HIGH-HIGH (HIHI) register. Use the [+] keys to select a very high efficiency trip point of of 000.0%. Then press the [F4] key to apply the new HIGH-HIGH (HIHI) setting.
To set the HIGH (HI) register, press the [F1] key seven times to select the HIGH (HI) register. Use the [+] keys to select a high efficiency trip point of of 125.0%. Then press the [F4] key to apply the new HIGH (HI) setting.

To set the LOW (LO) register, press the [F1] key eight times to select the LOW (LO) register. Use the [+] keys to select a low efficiency trip point of of 000.0%. Then press the [F4] key to apply the new LOW (LO) setting.
To set the LOW-LOW (LOLO) register, press the [F1] key nine times to select the LOW-LOW (LOLO) register. Use the [+] keys to select a very low efficiency trip point of 083.3%. Then press the [F4] key to apply the new LOW-LOW (LOLO) setting.
At the start of the day, the line supervisor should press the [TOP] key to reset the GOAL counter, press the [BOT] key to reset the ACTUAL counter, and then press the [RUN] key to start the GOAL counter.
When the employees go on break, the line supervisor should press the [HOLD] key to pause the GOAL counter during the break. When the employees return from break, the line supervisor should press the [RUN] key to release the GOAL counter from hold, allowing it to resume automatically counting up.
As the day progresses, the line supervisor and production employees should observe the GOAL and ACTUAL counts displayed on the PPT. By keeping the ACTUAL count as close as possible to the GOAL count throughout the day, the factory will produce the ideal number of widgets while simultaneously maximizing product consistency.
At the end of the shift, the line supervisor should press the [HOLD] key to pause the GOAL counter, and then record the end of day GOAL and ACTUAL totals in the production log.

To drive slave PPTs from a Master PPT, use RS-485 simplex wiring as shown below. RS-485 is rated to operate at distances up to 4000 cable feet, and the fan out characteristics of the RS-485 transceivers is better than RS-232. A three- conductor cable designed for serial communications will be needed. Signaworks suggests using Belden 9463 “Blue Hose” cable.
Connect the MASTER PPT to the slave PPT(s) as shown in the diagram below. The MASTER PPT RS-485 serial port can drive up to 63 RS-485 loads.
MASTER SLAVE #1 SLAVE #2
The PPT in MASTER mode is designed to be compatible with various slave marquees available from Signaworks. The PPT and slave marquees are shipped pre-configured from the factory if they are ordered together. The user must configure slave marquees if they are ordered separately. When in MASTER mode, the PPT sends numeric data to the slave marquees via ALI standard numeric sign protocol ([CTRL-B][address][numeric data][CTRL-C]) once each second at 19200bps baud.
GOAL data is sent to slave marquees with an address of “0” (30h). ACTUAL data is sent to slave marquees with an address of “1” (31h). DIFFERENCE data is sent to slave marquees with an address of “2” (32h). EFFICIENCY data is sent to slave marquees with an address of “3” (33h).
See the manual that came with the slave marquee for instructions on how to set the slave to an appropriate address and 19200bps baud.

The PPT serial port can be configured to accept commands from a central computer system. This is the COMMAND mode of operation. In this mode, the central computer system can issue commands to the PPT to read and write registers. PPT’s are addressable allowing commands to be directed at a specific PPT even when many are connected to the PC via an RS-485 communication link.
If a single PPT is being managed by a central computer, and the cable between the PPT and the computer will be no longer than fifty feet, RS-232 communication is preferable, otherwise RS-485 communications should be used.
When using RS-232, a three-conductor cable designed for serial communications will be needed. Signaworks suggests using Belden 9463 “Blue Hose” cable.
Typical wiring between an IBM PC compatible DB9 serial port and the PPT is illustrated below.

The PPT has many registers that can be written and read in real time via the serial port. Accesses to the PPT registers are provided via the COMMAND mode protocol which this manual section will describe in some detail.
Each PPT has a single character (byte) address ranging from space (20h) to “~” (7Eh) which is set on dip-switch SW1. Each unit’s address in a communications network must be unique or collisions will occur on the network. There is an ASCII chart detailing the correspondence between characters and the hexadecimal ASCII code numbers for that character.
All PPT commands begin with a CTRL-B character followed by the address of the PPT the command is directed too. All commands end with a CTRL-C character. The PPT uses the CTRL-B and CTRL-C characters to find the beginning and the end of command packets within the serial data stream.
Each PPT has the following serial port accessible registers:
Register Name | Register Code | Register Description |
GOAL | GO | 4 Digit GOAL Value, 0000 to 9999 |
ACTUAL | AC | 4 Digit ACTUAL Value, 0000 to 9999 |
PACE | PA | 4 Digit PACE Value, 0001 to 9999 |
GSCALE | GS | 4 Digit GOAL Scale Value, 0001 to 9999 |
ASCALE | AS | 4 Digit ACTUAL Scale Value, 0001 to 9999 |
HIGH-HIGH | VH | 4 Digit HIGH-HIGH Value, 0000 to 9999 |
HIGH | HI | 4 Digit High Value 0000, to 9999 |
LOW | LO | 4 Digit Low Value 0000, to 9999 |
LOW-LOW | VL | 4 Digit LOW-LOW Value, 0000 to 9999 |
KHOLD | KH | 1 Digit Keyboard Hold Flag, 0 to 1 (1 = HOLD) |
KDISABLE | KD | 1 Digit Keyboard Disable Flag, 0 to 1 (1 = Disabled) |
Any of the above registers can be read or written, in real time. The operation (Read or Write) and the register selected is specified by a 3-character opcode.
The first character in an opcode is an “R” character for a READ operation or a “W” character for a WRITE operation. The second and third characters of the opcode specify a PPT register. See the “Register Code” column in the table above for the two character codes that specify PPT registers.
Write opcodes are followed by numeric data as appropriate for the command. The numeric data must be fixed width, and cannot contain spaces or decimal points.

For example, to write “1” to the PACE register, the data section of the command must be “0001”. If the PPT time base is set to 1/10th second, “0001” is interpreted as 0.1 seconds. If the PPT time base is set to 1 second, “0001” is interpreted as 1 second.
When writing to the efficiency trip point registers (HIGH-HIGH, HIGH, LOW, LOW-LOW) the four digit value is interpreted by the PPT as a percentage in xxx.x format. For example, writing the value “1234” to the HIGH-HIGH register sets the very high efficiency trip point to 123.4%.
To write “1234” to the ACTUAL register of PPT “A”, use the opcode “WAC” (Write ACTUAL) with data “1234” as shown below.
STX | ADDR | OPCODE | DATA | ETX | |||||
CTRL B | A | W | A | C | 1 | 2 | 3 | 4 | CTRL C |
02h | 41h | 57h | 41h | 43h | 31h | 32h | 33h | 34h | 03h |
If the command is accepted, the PPT will respond with a single ACK character (CTRL-F, 06h).
To read the GOAL register of PPT “B” use the opcode “RGO” (Read GOAL) as shown below:
STX | ADDR | OPCODE | ETX | ||
CTRL B | B | R | G | O | CTRL C |
02h | 42h | 52h | 47h | 4Fh | 03h |
If the command is accepted, the PPT will respond with the requested data followed by an ACK character.
DATA | ACK | |||
1 | 2 | 3 | 4 | CTRL F |
31h | 32h | 33h | 34h | 06h |
If the PPT cannot interpret the command, it will respond with a NAK character (CTRL-U, 15h).

Before contacting ALI for technical support, please review the manual sections covering installation and operation.
If the marquee does not power up, check the power indicator lamp on LED1. This indicator. is connected directly to the PPT 5VDC power supply. If it does not light the 120VAC power wiring is probably incorrect.
If the PPT does not respond to the logic inputs, please observe the input indicator lamps on LED2 and LED3 while attempting to operate the PPT. When an input is activated, the corresponding lamp will light. The T-RST and B-RST inputs are asynchronous and will prevent GOAL and ACTUAL from counting as long as they are activated. Activating the HOLD input prevents the GOAL timer from running, even if the [RUN] button is pressed on the front panel.
If the PPT basic configuration operates, but the PPT serial port is not working, first check all serial port wiring and dip-switch settings. There are several indicator lamps on the PPT circuit board to help troubleshoot serial communications problems.
LED1 - ENB Lights when the RS-485 transmitter is active. LED1 - TXD Lights when the PPT is transmitting serial data. LED1 - RXD Lights when the PPT is receiving serial data.
The above LED’s should “flash” during serial communications because they only light during the transmission or reception of a character. When the serial data line is idle, all three LED’s should remain off.
If RS-232 echo is on (SW1 switch 8) then LED1 - ENB should never light because the RS-485 transmitter is disabled.
If RS-485 communications are being used, and LED1 - RXD remains on even though the serial data line is idle, the 485+ and 485- wires are probably reversed.
TJ1, the self-test jumper can be installed to check the numeric LED display and erase the PPT memory. When the PPT starts, if TJ1 is installed, additional startup code is executed. This code first performs a LAMP TEST, then the baud rate and address are displayed, and finally the PPT memory is erased which has the side effect of resetting all PPT registers to default values.
