1. INTRODUCTION
1.1. INTRODUCTION
Marquee Displays can display alphanumeric messages received from a host. The host may be a Marquee Controller (SM1000SMC), programmable logic controller, computer, or a master Allen-Bradley Bulletin 2706 Dataliner DL20 display. Either
RS232 or RS422/485 (multidrop) serial communication can be used. All message attributes and storage of messages is performed by the host.
Marquee Displays operate in a Slave mode. The slave mode allows up to 123 displays to have a unique address when using an RS422 network. Also, RS232 can be used. Serial commands are described later in this manual.

1.5. OPERATING TEMPERATURE
As listed above, the operating temperature of the display is 0
°
to 55
°
C. The display is capable of operating at these temperatures because of thermal management incorporated into its design. When operating at temperatures close to 55
°
C, the display will automatically dim itself to prevent it from overheating. If the internal temperature of the display exceeds 70
°
C, the unit will shut down and display OT at 5 second intervals until the internal temperature falls below 68
°
C. Since the dimming feature is based on the internal temperature of the display, the ambient temperature at which each stage of dimming occurs may vary between models. The dimming criteria is listed below.

At 75%, the dimming is very slight and hardly noticeable, however, as the internal temperature rises, the dimming becomes more noticeable. As the unit cools down, the display will automatically increase its brightness until back to 100%. A hysteresis is built into this feature to prevent any flickering effect.

2. INSTALLATION
2.1. INSTALLATION
Marquee Displays are fully inspected and tested before leaving the factory. They are packed in specially designed cartons to protect them from damage during shipment.
They should, however, be inspected upon receipt at the destination for visible or concealed damage. Claims for loss or damage should be filed with the carrier immediately. A claim for concealed damage is required when damage is not externally visible. Total Control Products will assist insofar as is practical in securing satisfactory adjustment of claims; however, all claims for loss and damage must be made by the purchaser to the carrier.
In the application of Total Control Products Marquee Displays, every precaution must be taken to provide a safe mechanical support system and proper electrical components for a safe electrical system. Local codes and ordinances governing wiring and installation practices must be observed.
In order to install your Marquee Display you must:
1. Survey the area where the display will be installed. Make sure that sunlight will not fall directly on the display surface since the LED characters will be washed out by direct sunlight. While the unit is rated as NEMA 12, it was not designed for continuous use under dripping liquids such as water pipes, condensation lines, or roof leaks.
2. Locate a source of 115VAC power and determine how you will route the power to the Marquee Display. Check the specifications tables for power requirements.
3. Decide if you will use RS232 or RS422 communications from the host and how you will route the cable to the Marquee Display.
2.2. MECHANICAL MOUNTING
This section describes the mechanical aspects of installing the Marquee Display. It is a good idea to test the display and set the dip switches before installing it. This can be done by installing a temporary power cord to the AC connections and attaching the host RS232/422 connections. Refer to the Section 3 for instructions on connecting AC power and host cables.
QUICKMARQUEE DISPLAY 7
2.3. MARQUEE DISPLAY MOUNTING HOLE
The Marquee Display system was designed to be mounted in several configurations.
There is a standard mounting hole in each end wall of the Marquee display. Each end wall is reinforced with a 4 inch square 12-gauge steel plate with a welded nut to accept a 3/8 - 16 inch bolt.

2.8. MULTIPLE UNIT BRACKETS
When you order a QM4204ROA Display, you will get two QM2204ROA units permanently stacked together. The display is hung using a stacked hanging bracket
(SM1001SHB). A back-to-back configuration of two QM4204ROA Displays is hung using a back-to-back stacked hanging bracket(SM1001BSB). These two brackets are
ONLY for hanging QM4204ROA Displays.

2.10. POWER CABLE/COMMUNICATIONS CABLE
ACCESS PLATE
The power cable/communications cable access plate cover should be removed and then punched to accept raceway fittings that will terminate your cable runs. If your local plant/electrical codes allow, this fitting will terminate a flexible whip from your rigid power/communications wire runs.
The power cable must be installed according to local codes. Make sure your power source can support the total electrical load connected to it. Provide proper circuit protection and mechanical raceways. To make installation easier, plan on using a flexible raceway for the last three feet or longer if allowed by code. Also, leave at least three feet of wire pulled past the final fitting to allow dressing when connecting to the Marquee display terminal.
To gain access to the connection terminals, there are two cover plates (a large one and a small one) on the top of the Marquee Display.

3. ELECTRICAL
3.1. GROUNDING
IMPORTANT!
When connecting a host device to one or more Marquee Displays it is very important to have each device connected to a common ground and common power supply.
Good grounding cannot be over stressed. A complex system must have only one ground point for common power supplies and signal returns to prevent ground loops.
We recommend Belden 9463 wire or other quality 22 gauge twisted shielded pair wire and connecting the shields to common ground at both ends of the wire.
Proper grounding of the Display System will prevent symptoms that appear as malfunctions during normal "RUN" operation.
3.2. WIRE RUNS AND WIRING
DO NOT route control or data wires with power or high voltage wires other than
Marquee power. Always use twisted shielded pair wire or Belden 9463 which provides a very effective shield against electrostatic and magnetic coupling.
3.3. ELECTRICAL CONNECTIONS
This section describes the electrical connections to the Marquee Display. The display should be tested prior to installing it in a permanent location. The following drawing shows the bracket containing the terminals and dip switches. This bracket if found inside the display, under the large terminal cover plate.

Use the information in this section to connect AC Power and host interface. Make the appropriate switch settings for the address, baud rate and character size. Once you
15
are sure all connections and settings are correct, turn on the power and watch the unit go through the self test cycle. When the self test has completed, the display will go blank and wait for commands from the host device.
3.4. CONNECTING AC POWER (TERMINALS L, G, N)
Connect the 115VAC hot lead to Terminal L. The neutral lead should be connected to Terminal N. Terminal G earth ground must be connected to a reliable low impedance path to protect the display from electrical noise. This ground connection will also protect personnel from electrical shock in case of equipment failure. The terminal strip is shown below.

3.6. RS232 CONNECTIONS (TERMINALS 1-3)
RS232 is the most common interface specification among controllers supporting serial communication. This specification allows connection of only one Marquee display, with a maximum recommended cable length of 50 feet. Consider using
RS422/485 for applications that exceed these limitations. If you are connecting the
Marquee Display to a Marquee Controller, the RS422 protocol will be used.

3.8. OPEN COLLECTOR OUTPUT
The Marquee Display is capable of controlling an open collector circuit that can drive a relay with up to 150 ma. at 24 VDC. A two position pluggable terminal strip is used to facilitate the connection. The relay should be connected to the terminal strip at terminal 1. A ground connection is provided at terminal 2 to establish a common ground with the power supply driving the relay.

3.9. DISPLAY CONFIGURATION (Switch A)
On power up, the Marquee Display will perform a number of functions in order to properly configure itself. The Marquee starts by displaying "AUTO
CONFIGURING", at which point it is determining the number of displays that make up the complete sign. For example, a QM4204ROA is made up of 4 individual displays or lines. Further configuration is done through DIP switches labeled A and
B:

3.11. CHARACTER SIZE SELECTION (Switch A)
Four different character size settings exist for the Marquee. Unless you are using a multilined Marquee such as a QM4204ROA, the default setting (2.1" and 4.8" characters) should be selected. The character size settings are shown below.

Why different character size settings? Their are two reasons for providing this feature. First, depending on the character size requirements of the application, the
2.1" ONLY and 4.8" ONLY settings may simplify the programming in the host device. Second, the different character size settings allow specific models of marquee displays to be compatible with specific devices. For example, when slaving a
QM4204ROA marquee from a 4 line SMART SIM/MC or ALLEN BRADLEY
DL20/DL40, it is necessary for the 4.8" ONLY character size setting to be selected.
Each character size setting affects the way the line number field in the slave protocol is interpreted. Below is a table containing these differences. See also the communications section of this manual.

3.14. ADDRESS SELECTION (Switch B)
Upon power up, the Marquee Display will read the address selected by switch B and display that address during the power up display cycle.
The Marquee display address can be set from 1 to 127. Note that addresses: 0, 6, 10,
13, and 18 are reserved and would be interpreted as address 127:
Marquee display address 127 is a special slave address that will display all slave messages regardless of their address. Marquee display addresses need not be unique, a Marquee Display network may have two or more units with the same address as in the case of back to back units that display the same message on both sides.
The display label showing the address select table is shown below. Starting at address
1, the switch settings are selected using a binary format, with switch 7 being the most significant digit. Switch 8 is not currently used.

3.15. FINAL CHECKS
After all the connections are made, including power and communications, the power should be applied and the unit tested for proper operation. If you change any switch setting, the power must be cycled in order for the new setting to be read.
Once proper operation has been established, the display is ready to install in a permanent location. See Section 2 for mechanical installation details.
The terminal cover plate should be securely fastened to the top of the Marquee
Display to re-establish its NEMA 12/4 rating.
When the display is mounted in a permanent location, turn on the power and view the display. As part of the Marquee Display start-up, it will light up all display segments
22 QUICKMARQUEE DISPLAY
and execute a self test. The display will show which switch setting are selected. It will then go blank and wait for commands from the host device.
A sample self test is shown below.

4. COMMUNICATION
4.1. INTRODUCTION
This section of the manual covers the slave protocol. The information in this section is presented using conventions that are defined as follows.
1. The “/” character is used to separate the fields of the protocol for the purpose of presenting the information and is not actually part of the protocol.
2. Words contained within the “<“ and “>“ symbols are not part of the protocol but references to the actual information to be substituted in place of the word and the symbols. For example, in place of <text>, one would put the actual message to be displayed.
3. The ASCII code for Control (CTRL) characters, Carriage Return and the
ESCAPE character can be found in the Appendix section of this manual.
Wherever ESCAPE or Control is used in the protocol, the equivalent ASCII code should be used. Do not use the characters that make up the word ESCAPE or Control.
4. Whenever applicable, the decimal representation of the ASCII code is provided in parenthesis. For example: A (65). The Appendix section of this manual contains a complete ASCII code table.
QUICKMARQUEE DISPLAY 25
4.2. SLAVE PROTOCOL FORMAT
All the information that creates a message must be formatted and sent by the host computer or programmable logic controller. Restrictions for the various fields are listed in each section.

The following AUTO REPEAT MODE allows messages to be downloaded into the
Marquee and then left to run continuously. There is room for approximately 5000 bytes of message storage.
Control S - This command followed by a slave address, a don't care byte and a CR, will clear out the auto repeat buffer and if it is in the auto repeat mode, it will stop. It is a good idea to always start out with this command before downloading a new sequence of messages.
/CTRL S / <slave address> / <don't care> / carriage return
* Don't care bytes cannot be a CR, CTRL R, or CTRL F. We suggest sending the address again.
Control Y - This command will tell the slave marquee to add the following text field and mode control information to it's auto repeat memory. This string can be no longer than 255 bytes and also must be terminated with a slave number, a don't care byte, and a CR. (This is part of the 255 byte limitation.) A particular message can also be added to the buffer without breaking up the display flow, this is particularly useful for long scroll mode messages. The format is:
/CTRL Y / <text field> / <slave address> / <don't care> / carriage return
Control W - This command will enable the AUTO REPEAT mode. There are three modifiers that are associated with this command:
ASCII
0

2
DECIMAL DEFINITION
48 Resume where stopped, even if its in the middle of a message. The message must be a
49
50 line type message, not a roll or smooth scroll.
Resume at the beginning of a message run previous to stopping.
Start at the beginning of the buffer.
No modifier with this command is the same as using a 2 modifier. Again the message must contain an address, don't care byte, and a carriage return. The format is:
/ CTRL W / <modifier> / <slave address> / <don't care> / carriage return
This command can be used in conjunction with the stop command that is discussed next.
Control X - This command will stop the auto repeat mode without destroying the buffer's content, which will allow the unit to start up using CTRL W. This command is useful when an alarm message is to be posted. The auto repeat can be stopped and
QUICKMARQUEE DISPLAY 27
28
a regular message can be sent via the standard protocol. Then the auto repeat mode can be restarted. The format is:
/ CTRL X / <slave address> / <don't care> / carriage return
4.3.1. AUTO REPEAT - TEXT FIELD FORMAT
/CTRL Y / <text field> / <slave address> / <don't care> / carriage return
The text field that is sent to the display has it's own format to allow the display mode, line number and wait times to be changed throughout the message program. If the user simply sends text without any mode control codes, the display will default to line mode, line 1 and wait time of one second. To change the modes the following sequence must be sent before the text string in the text field;
1. An ESC (Escape) code and a ASCII T will tell the slave that the following data is meant to be a text string with attributes.
2. The line number will tell the slave what line the text is to be displayed on.
Line number is an ASCII character in the range of "0" (49) to "<" (60) and "O" (79).

4. Wait time will tell the slave how long, in seconds, it should wait before starting the next message or the time between updating the display for multiple display messages.
Wait time is a ASCII two digit number that gives the delay time between updates of a line in a single line mode or all lines in all line mode. It can range from 0 (48) / 0
(48), to 9 (57) / 9 (57) seconds.
The format of the text field data is:
ESCAPE / T / line number / display mode / two byte wait time / text...../
The text is any printable ASCII character or variable field. The color switch is also allowed for use with the tricolor displays. In line mode, the lines of text will automatically be broken up and centered. Remember, this is the format for the text field, and is included as part of the whole message string.
QUICKMARQUEE DISPLAY 29
4.3.2. AUTO REPEAT - TEXT FIELD VARIABLE
The text field may also have an escape sequence embedded in it to signal that a variable is to be inserted there. The sequence is a ESCAPE (27) to tell the slave there is a field coming up, a V (86) to tell the slave a variable number is to follow, and an
ASCII number from 0 (48) to 9 (57), which is the actual variable number that will be inserted at this point in the message program. The format is:
/ ESCAPE/ V / <ASCII digit 0 to 9> /
Where 0 to 9 is the variable number. The slave marquee variable can be a string of 32 displayable ASCII characters. There can be up to ten variables. If the message is being displayed that is to have a variable embedded but no variable exists, then nothing will appear in its place. The slave can be loaded with these variables independent of the auto repeat mode. To send over a variable, the sequence is as follows:
/CTRL V / <variable number (ASCII 0 to 9)> / <Text (up to 32 characters)>/
<address> / <don't care> / carriage return /
The variable feature allows users to send over messages that should remain constant but embedded with a message(s) that can change, i.e., time of day, temperature, parts count, etc.

This field can contain up to 250 viewable characters. Any valid ASCII character, upper or lower case, can be sent. Control codes do not apply except for Control F
Control R and Control U.
Control F will cause the characters of the entire string to flash. A second Control F will cancel the flash mode.
Control R is interpreted as a reset command and all data registers in the Marquee
Display are cleared and you will be required to transmit new characters for display.
In other words, if you were to send 10 characters, then a Control R, your previous 10 characters are lost and any following characters would be accepted by the Marquee
Display. Control R also resets the flash status to not flashing. It is recommended that a Control R be sent to all Marquee displays when the host controller powers up, because when a serial port powers up it may inadvertently transmit erroneous data.
Control U has been added to allow changing the text color for tricolor displays. The format is as follows:
/Control U/ <color character>/ where,
<color character > = R (82) for red, G (71) for green and Y (89) for yellow.
The default color is red. This command can be used multiple times within the same text string.

This is a one byte ASCII character ranging anywhere from 1 through 127 decimal (1 through 7F Hex). It should be noted that addresses 0, 6, 10, 13, and 18 are illegal addresses. Any Marquee display addressed as 127 will understand any data that is transmitted regardless of what the address is in the packet. In addition, any packet containing the address 127 is understood by all Marquee displays regardless of their addresses. This allows you to efficiently route a message to all displays. Multiple
Marquee displays on an RS422/485 communication line can have the same address and they will all respond to a message sent to that address.
Remember, this field must be a ASCII character, not a decimal number. For example:

5. APPLICATIONS
5.1. HOST DEVICES
The Marquee Display can be a slave to many different host devices. In general, any device capable of formatting an ASCII character string that has either an RS232 or
RS422 port is a suitable host device. Host devices can be divided into two categories, devices already designed to communicate with the Marquee Display and devices requiring additional programming.
An example of a device that would require programming to allow it to communicate with a Marquee Display is a personal computer or PC. A PC has the hardware necessary for communicating to a Marquee Display but lacks the user program to format and send the text strings. With a PC, a user is required to write a program in a language such as BASIC or C using the information provided in the Communications section of this manual.
Devices currently available that are capable of communication with the Marquee
Display are listed below.
1) MARQUEE CONTROLLER: This product is design specifically for the Marquee
Display and may be used with all models of Marquees.
2) SMART MC & SMART SIM Series Displays: These are panel mount displays that are capable of sending messages to a Marquee Display. Only certain models of the Marquee Displays may be used with these products.
3) ALLEN BRADLEY DL20 & DL40 Series Displays: These Allen-Bradley products are very similar to the SMART MC and SMART SIM products. Only certain models of Marquee Displays may be used with these products.
These devices are mainly designed for interfacing to PLCs (programmable logic controllers). The advantage to these devices is that they handle formatting and sending the text string to be displayed on the Marquee. All the user has to do is enter the messages into the unit and trigger it when required. Since these devices handle communications to the display, the user can skip the Communication section of this manual but must be sure to setup the display correctly as indicated in Electrical section. Specific applications involving this equipment are covered below.

Many users choose to slave one or more Marquees from a host computer. Typical host computers are PCs, main frame systems or PLCs with a BASIC module or
ASCII module. When slaving a Marquee from a host computer, it is required that the host computer store and format the messages to be displayed on the Marquee. To do this, a computer program must be created using the information presented in the
Communications section of this manual. Depending on how elaborate the application, this may be accomplished with a simple BASIC program or may require a complex program in a more powerful programming language. Below is a sample basic program for displaying messages on a Marquee display.

Marquee displays can be connected to the Total Control Products host device called a Marquee Controller (SM1000SMC). The Marquee Controller stores up to 1022 unique messages each with their own unique message attributes in its 31K of user memory.
The Marquee display(s) will be connected to the SMC- and SMC+ terminals of the
Marquee Controller. Up to 32 Marquee Displays can be connected to the SMC- and
SMC+ terminals with a maximum distance of 10,000 feet without the use of in line amplification. Using in-line RS422 amplification allows up to 123 separately addressable Marquee Displays to be connected to the SMC-, SMC+ terminals.

5.4. ALLEN-BRADLEY DL20 & DL40 COMPATIBILITY
Marquee Displays can be connected to the Allen-Bradley Bulletin 2706 DL20 or
DL40 Data Liner displays serial RS232 or RS422 port. Up to 32 Marquee Displays can be connected to the RS422 output port of the DL20 display at a maximum distance of 10,000 feet without the use of in-line amplification. Using in-line RS422 amplification allows up to 111 separately addressable Marquee Displays to be connected to the RS422 output of the Allen-Bradley DL20 without distance limitations.
Connect the Marquee Display to the RS422 output of the DL20 using a 100% shielded twisted pair cable with drain wire. Marquee address and baud rates must match those selected on the DL20 hardware and the ``out to slave" and correct
``slave number" must be programmed as message attributes. Also, be sure to select the correct character height on the Marquee. See the chart at the end of this section for setting the character mode.

Note that it is also possible to use the RS232 output of the DL20 to connect to one
Marquee Display, however, the distance limitation is 50 feet.
When slaving a Marquee Display from a DL20 or DL40, Marquee selection is very important. Below is a chart showing which Marquee can be used for each Dataliner configuration.

When using the Dataliner displays with a Marquee, avoid using scroll mode since this tends to slow the update time to the Marquee Display.
5.5. SMART SIM & SMART MC COMPATIBILITY
Marquee Displays can be connected to the SMART SIM or SMART MC displays serial RS232 or RS422 on port 3. Up to 32 Marquee Displays can be connected to the RS422 output port of the display at a maximum distance of 10,000 feet without the use of in-line amplification. Using in-line RS422 amplification allows up to 111 separately addressable Marquee Displays to be connected to the RS422 output without distance limitations.
Connect the Marquee Display to the port 3 RS422 output using a 100% shielded twisted pair cable with drain wire. Marquee address and baud rates must match those selected in the host display and the ``out to slave" and correct ``slave number" must be programmed as message attributes. Also, be sure to select the correct character height on the Marquee. See the chart at the end of this section for setting the character mode.
