DESCRIPTION  
OVERVIEW  
The CM9760 master distribution amplifier (CM9760-MDA), version 2.05 or higher, is a  
16-channel video distribution amplifier that distributes video to multiple devices without  
image degradation. As illustrated in Figure 1, each of the 16 channels (video inputs) has  
four independent video outputs. Each of the video outputs can be connected to any of the  
following devices:  
Monitor  
Video printer  
Video cassette recorder (VCR)  
Digital video recorder (DVR)  
Multiplexer  
Matrix switcher

Figure 1. System Configuration (Rear Panel View)  
The MDA can be programmed using a PC or a CM9760-KBD, KBD200A, or KBD300A  
keyboard. Each of the 16 video inputs can be individually programmed to insert time/date  
and title information on each video output, and each video output is selectable to include or  
exclude time/date and title generation. Character positions are adjustable horizontally and  
vertically on-screen with digital brightness control. Programming also includes cable  
compensation for up to 1,500 feet (457 m) of RG59/U coaxial cable.  
The MDA can act as a stand-alone time/date and title generator or can be synchronized to  
a System 9740/System 9760® as a matrix time/date and title generator:  
As a stand-alone unit, an MDA can be addressed to provide the master time and date  
for up to 63 MDA slave units.  
NOTE: Up to 16 MDA units  
can be daisy-chained. If  
more than 16 MDAs are  
required, a CM9760-CDU-T  
must be used.  
When connected to a System 9740/System 9760 CC1 port, up to 64 MDAs can accept  
the master time and date from the 9740/9760.  
In addition, note the following about the MDA:  
Using the RS-232 or RS-422 communication standard, the MDA can accept text  
messages from third-party equipment. A message can contain up to 24 characters. Up  
to five lines of messages can be displayed simultaneously. The messages can be  
inserted onto any video channel independently. For additional information, refer to the  
Set Message Text section of this manual.  
All video inputs are individually ground isolated to prevent ground loops, eliminating  
the need for ground loop isolation transformers.  
Battery backup protects programming information for a minimum of one year.  
The MDA does not pass Coaxitron® signals; however, the MDA can be used with  
Coaxitron products such as the CM6700, CM6800, and the CM9760-CXTA.

MODELS  
CM9760-MDA  
Master distribution amplifier with time and date and title, 120 VAC,  
60 Hz (FCC)  
CM9760-MDA-X  
Same as CM9760-MDA except 230 VAC, 50 Hz (CE)  
MOUNTING  
Install the MDA in a standard 19-inch (48.26 cm) equipment rack using standard mounting  
hardware. The MDA occupies 5.25 inches (13.34 cm) of vertical space, or three RU (rack  
units).  
VERY IMPORTANT: If  
you are going to use RS-232  
communication, you must  
open the case to set the DIP  
switches—do so BEFORE  
mounting the MDA unit in  
the rack. See the section on  
Communication Ports Setup  
and the section on Connect-  
ing the MDA to an External  
PC for information.

COMMUNICATION  
Communication between MDA units, System 9760 CC1 (controller), System 9740 CC1 (con-  
troller), KBD200A or KBD300A keyboard, or a host PC is accomplished using serial RS-232,  
RS-422, or RS-485 transceivers that can be configured by DIP switches on the PCB (printed  
circuit board). The factory default for both COM 1 and COM 2 ports is RS-422.

COMMUNICATION PORTS SETUP  
NOTE: COM 1 is config-  
ured at the factory for  
RS-422 communication. To  
communicate via RS-232,  
you must open the case and  
change an internal DIP  
switch.  
There are two sets of DIP switches inside the MDA for selecting the type of interface for the  
communication ports (COM 1 and COM 2).  
The unit comes from the factory configured for RS-422. If your communication scheme is  
RS-422 and you intend to program the MDA(s) through a CM9760-KBD, KBD200A or  
KBD300A keyboard, leave the settings alone.  
However, if the communication scheme is different than RS-422, or you are going to  
program the MDA through a PC (which requires RS-232), do the following to change  
settings. (Generally, programming through a PC is easier than programming through a  
System 9760 keyboard. For more information, refer to the Programming section.)  
1. Remove the 10 screws on the top cover and lift it off.  
2. Refer to Figure 2 for the location of the switches for COM 1 and COM 2. Refer to  
Table A for the switch settings.  
3. Replace the cover.

ADDRESS SETUP FOR DAISY CHAINING  
NOTE: When upgrading  
CM9760-MDA units in a  
daisy chain to version 2.xx,  
version 2.xx units must be  
the first units in the daisy  
chain. Any CM9760-MDA  
version 1.xx units must be  
connected in the chain fol-  
lowing all version 2.xx units.  
CAUTION: Switch 7 clears all entered data from memory.

SETTING UP A UNIT AS THE MASTER CLOCK  
You can synchronize several CM9760-MDAs even when connecting them without a  
CM9760 switching system. The master clock can be any unit ID as long as it is the first unit  
of the chain. Make it the master clock by turning on switch 8 of the unit ID DIP switch on the  
rear panel. This unit will synchronize the time and date of all units connected to it. Only one  
unit can be a master clock. The remaining units are the slave units (unit ID DIP switch 8 is  
in the OFF position, which is the default setting). A single MDA unit can provide the master  
time and date for up to 63 slave units.  
RESETTING TO FACTORY DEFAULTS  
CAUTION:  
Switch 7 clears all  
entered data from  
memory.  
You can reset the CM9760-MDA to factory defaults by turning on switch 7 of the UNIT ID  
DIP switch located on the rear panel. Do this before powering up the unit. Now, turn on the  
CM9760-MDA. This will clear all data stored in memory, such as titles and port configura-  
tions and resets them to the defaults as shipped from the factory. Then turn off the  
CM9760-MDA and turn switch 7 off.  
DO NOT turn off the  
MDA before the reset  
process finishes. This  
can lock up the MDA and  
render it useless. The  
length of time to leave  
power on can vary from a  
few seconds to several min-  
utes (for systems with a lot  
of equipment). To determine  
when the process finishes,  
look at the monitor outputs  
as resetting puts everything  
back to default status.

CLEARING TITLE/TIME/DATE TEXT DISPLAY ON ALL CHANNELS  
You can clear title/time/date text on all CM9760-MDA channels using a DIP switch method.  
To do so, proceed as follows:  
1. Turn off the MDA.  
2. Set the MDA to unit ID 33:  
a. Set DIP switches 1, 2, 3, 4, and 5 to the OFF position.  
b. Set DIP switch 6 to the ON position.  
3. Turn on the MDA.  
A 30-second timer starts.  
4. Before the 30 seconds elapses, change the unit ID to a setting other than unit ID 33  
using the appropriate DIP switch settings.  
After 30 seconds have elapsed, the MDA checks whether the unit ID is different from  
the initial setting of 33. If the unit ID has changed, the MDA title/time/date text display  
is cleared.  
Note the following:  
The title/time/date text can be programmed again using the PC or a CM9760-KBD,  
KBD200A, or KBD300A keyboard.  
If the MDA must be set back to unit ID 33, set the unit ID after the title/time/date text  
has cleared.

1. Connect the remote video sources to the input BNC connectors on the rear panel of  
the MDA (refer to Figure 33). Refer to Table C for video coaxial wiring distances. (Note  
that when wiring inputs it is good installation practice to label each video input in case  
troubleshooting is required.)  
2. Connect cables from the output BNC connectors on the MDA’s rear panel to the input  
connectors of monitors, VCRs, switchers, etc. (refer to Figure 33). Refer to Table C for  
video coaxial wiring distances.  
Although the MDA does not pass Coaxitron signals, it can be used with Coaxitron products  
—such as the CM6700, CM6800, and CM9760-CXTA—by installing the MDA after the  
Coaxitron equipment (refer to Figure 45 and to Figure 46).

DATA CONNECTIONS  
The MDA can be connected to an external device via RS-232/422/485 standards. The  
distance at which it can be installed away from another device depends on the communica-  
tion type and the wire size of the cable. Maximum cable distance for RS-232 serial data for  
18-24 AWG is 50 feet (15.24 m) while the maximum for RS-422 and RS-485 with 24-gauge  
wire is 4,000 feet (1,219 m). For longer distances, junction boxes and heavier cable can be  
used. Pelco recommends using shielded twisted pair, such as Belden 9843 or similar cable,  
meeting or exceeding the basic requirements for EIA RS-422/485 applications. Decide  
where the MDA will be located and follow the mounting and connection instructions.  
CONNECTING THE MDA TO A SYSTEM 9740/9760  
CONTROLLER  
The rear panel of the MDA contains two RJ-45 modular connectors for external data  
communication using RS-232, RS-422, or RS-485 standards. Connect the COM 1 port on  
the MDA’s rear panel to the next available RJ-45 output connector on the System 9740/9760  
controller (refer to Figure 4 for an illustration of MDA connection to a System 9760 control-  
ler.) The System 9740/9760 controller port to which the MDA is connected must be  
programmed for proper communication with an MDA. Refer to the System CM9760-CC1  
manual or to the System CM9740-CC1 manual for information about selecting and  
configuring the RJ-45 ports on the System 9740/9760 controller.

CONNECTING THE MDA TO AN EXTERNAL PC  
Perform this step if you are going to program your CM9760-MDA unit using a PC (personal  
computer).  
NOTE: The CM9760-MDA  
is configured at the factory  
for RS-422 communication.  
To communicate via RS-232,  
an internal DIP switch must  
be changed. Refer to the  
Communication Ports Setup  
section.  
Refer to Figure 5 and make a cable to connect the MDA to the PC. The figure shows a  
typical nine-pin sub “D” connector for the PC’s COM 1/COM 2 serial port. Computers may  
differ regarding connector types and pin-outs. Therefore, always refer to the computer’s  
manual to determine proper pin-outs.  
If more than one MDA is to be programmed using a PC, note the following:  
A maximum of 16 MDA units can be daisy-chained. To daisy-chain up to 16 MDA units,  
connect the RS-422 output of the first MDA unit to the RS-422 input of the second  
MDA unit and continue this method until the last MDA unit is connected (refer to Table  
D and to Figure 39).  
If more than 16 MDAs are to be connected to a PC, a CM9760-CDU-T must be used.  
Refer to Figure 40 for an example of connecting over 16 MDAs to a PC. Note that a  
maximum of 64 MDA units can be connected to a PC for programming.

SET MESSAGE TEXT  
The CM9760-MDA accepts message text to meet the needs of applications that require  
real-time information overlaid on the video being viewed. Up to five lines of message text  
can be sent to the MDA simultaneously. Each line can contain up to 24 alphanumeric  
characters. The message text can be inserted onto any MDA channel independently.  
NOTE: A list of characters  
supported by the MDA for  
display of message text is  
provided in Appendix B.  
The CM9760-MDA Setup program provides a tool that demonstrates support of the  
message text feature of the MDA. The program allows message text to be sent from the PC  
to an MDA or to an MDA daisy chain. The PC application is designed as an example of  
message text operation for third parties who wish to develop their own message text  
interface to the MDA. (Refer to the Applications section of this manual for an application  
diagram and to Appendix C for a listing of the message text insertion commands supported  
by the MDA.)  
To set message text using the CM9760-MDA Setup program, proceed as follows:  
1. Open the Position Text dialog box and do the following:  
a. Position the title/time/date text in the top or middle of the screen (the text should  
not be positioned at the bottom of the screen).  
NOTE: Positioning the title/  
time/date text in the top or  
middle of the screen in the  
Position Text dialog box  
ensures that you will be able  
to view the message text  
that is displayed on a moni-  
tor. (For information about  
the Position Text dialog box,  
refer to the Set Display  
b. Close the Position Text dialog box.  
2. Open the Message Text Editing dialog box by clicking Edit on the CM9760-MDA  
SETUP dialog box and then clicking Message Text. The Message Text Editing dialog  
box, Figure 31, appears.  
section of this manual.)  
Figure 31. Message Text Editing Dialog Box  
3. Enter the Unit ID number (1-64) of the MDA unit for which you want to set message  
text, and then press Return. Note that all subsequent changes using the  
CM9760-MDA Setup program will be applied to the unit ID number that was entered.  
4. Enter the channel (camera) number (1-16) for which you want to set message text,  
and then press Return. Note that all subsequent changes using the CM9760-MDA  
Setup program will be applied to the channel number that was entered.

5. Determine whether you wish to apply message formatting changes to all channels.  
(Changes to message formatting involve programming the Format, Rows to Display,  
Rows of Separation, and Display Time settings that are provided in the lower right-  
hand corner of the Message Text Editing dialog box. Information about setting  
message formatting is provided in step 7 below.)  
To apply message formatting changes to all channels, select the Global checkbox  
option.  
6. Determine whether you wish to display the command transactions between the MDA  
and the PC in hexadecimal and ASCII formats. (For additional information about the  
command transactions that are displayed, refer to the Showing Commands section  
later in this manual.)  
To display the command transactions, do the following:  
a. Select the Show Commands checkbox. The Command Data window, Figure 32,  
appears in front of the Message Text Editing dialog box.  
Figure 32. Command Data Window  
b. Do either of the following:  
Move the Message Text Editing dialog box in front of the Command Data  
window by clicking the Message Text Editing dialog box. Each time a  
command is sent from the PC to the MDA, the Command Data window  
appears. After viewing the command transactions, move the Message Text  
Editing dialog box in front of the Command Data window again.  
Minimize the Command Data window. Whenever you wish to view a  
command transaction in the Command Data window, click the Command  
Data button in the taskbar on the Windows desktop. Then minimize the  
Command Data window again.

7. Set the message text format characteristics in the lower right-hand corner of the  
Message Text Editing dialog box by programming the following information:  
Format—Specifies the positioning of title/time/date text and message text. Select  
the desired setting in the list box using the up or down button:  
Titles on Top specifies that title/time/date text is to be positioned above  
message text (default setting).  
Messages on Top specifies that message text is to be positioned above title/  
time/date text.  
Rows to Display—Specifies the number of rows (lines) of message text to be  
displayed. In addition, the Rows to Display field also specifies the number of  
rows of text that can be scrolled (for information about scrolling text, refer to the  
Scrolling Message Text section later in this manual). Select the desired setting in  
the list box using the up or down button. The range is 0-5 rows. The default  
setting is 0, which disables the message text feature.  
Rows of Separation—Specifies the number of blank rows to be set between the  
title/time/date text and the message text displays. Select the desired setting in  
the list box using the up or down button. The range is 0-28 rows. The default  
setting is 0.  
Display Time—Specifies the number of seconds that message text is to be  
displayed. Enter a value ranging from 0-9999 seconds. The default setting is 0,  
which allows the message text to be displayed for an indefinite period of time or  
until the message text is overwritten.  
8. Send the formatting changes set in step 7 above to the selected unit and channel(s)  
by clicking the Send Current Formatting button, which is located below the Sample  
Display screen.  
The Sample Display screen then displays the current formatting determined by the  
Format, Rows to Display, and Rows of Separation settings selected in step 7. In  
addition, the default message text for each row to be displayed appears. The default  
message text for rows 1-5 is as follows: Row 1 Message, Row 2 Message, Row 3  
Message, Row 4 Message, and Row 5 Message.  
Figure 33 provides an example of a Sample Display screen and the associated  
formatting settings (titles on top, three rows to display, and two rows of separation).  
Note that the Sample Display does not show the actual position of the title/time/date  
and message text on the monitor on which the text is to be displayed but rather shows  
the position of the title/time/date text in relation to the message text. The actual  
positioning of the text is shown in the Position Text dialog box:  
If message text is set and Titles on Top is set as the format, the Position Text  
dialog box shows the positioning of the title/time/date text.  
If message text is set and Messages on Top is set as the format, the Position  
Text dialog box shows the positioning of the message text.  
(For additional information about the Position Text dialog box, refer to the Set Display  
section of this manual.)

9. Enter and send message text to the selected unit and channel for the desired number  
of rows (as determined by the Rows to Display value set in step 7 above). For each  
row, the message text can contain a maximum number of 24 alphanumeric characters.  
If the desired number of rows is 1, enter the message text into the Row 1  
message text entry box and then click the Send Row 1 button.  
If the desired number of rows is more than one, you can enter and send the  
message text for each row individually or you can enter the message text for all  
rows and then send the message text for all rows at one time:  
To send the message text individually for each row, click the Send Row x  
button (x = 1, 2, 3, 4, or 5) as appropriate.  
To send the message text for all rows at one time, click the Send Messages  
button.  
The desired message text is displayed on the number of rows selected to display  
message text on the current MDA channel.

The following sections provide additional information about functions that can be performed  
from the Message Text Editing dialog box.  
Showing Commands: You can display command transactions between the PC and the  
MDA by selecting the Show Commands checkbox in the Message Text Editing dialog box.  
The Command Data window displays the command sent to the MDA and the response sent  
from the MDA each time you click a command button in the Message Text Editing dialog  
box. The command transaction is displayed in hexadecimal format and in ASCII format.  
Figure 34 provides a sample of a Command Data window. The message Hello World was  
sent from the PC to the MDA using the Send Row 1 command button.  
Figure 34. Sample Command Data Window  
Note the following:  
The ASCII equivalent of hexadecimal data 00 to 1F and hexadecimal data 80 and  
beyond is represented as dots.  
When the MDA acknowledges the command that was sent to it, the MDA responds by  
sending A2 as shown in Figure 34. If the MDA does not acknowledge the command  
that was sent to it, the MDA responds by sending AA.  
For additional information about message text commands, refer to Appendix C in this  
manual.  
Scrolling Message Text: If you have set message text on a selected unit and channel for  
a specified number of rows, the MDA allows you to scroll message text to allow a new  
message to be displayed.  
To scroll message text, do the following:  
1. In the Rows to Display formatting list box, specify the number of text rows that can be  
scrolled and displayed.  
2. Send the formatting to the selected unit and channel(s) by clicking the Send Current  
Formatting button.  
3. In the Scroll Text entry box, enter the desired message text and then click the Scroll  
Text button.  
Message text scrolls as follows. Each row that is scrolled moves upward one row. As a  
result, the first row of message text is overwritten. The new message is displayed in the  
bottom row, which is determined by the number of rows specified in the Rows to Display  
formatting setting.

An example of message text scrolling is as follows. If the Rows to Display field specifies  
that three rows can be scrolled, the following occurs when message text is scrolled:  
Message text on row 2 moves up to row 1. The message text that previously appeared  
on row 1 is overwritten.  
Message text on row 3 moves up to row 2.  
The new message to be displayed (scroll message) appears on message row 3.  
Note that you can view the scrolled text in the message text entry boxes by clicking the Get  
Messages button.  
Loading Default Message Text: You can display the default message text in the message  
text entry boxes by clicking the Load Default Messages button. Default message text  
appears as follows:

Display, Rows of Separation, and Display Time fields by clicking the Load Default Format  
button. The following default settings are displayed:  
In the Format list box, Titles on Top is displayed and is highlighted. Titles on Top  
specifies that title/time/date text is to appear above message text.  
In the Rows to Display list box, 0 is displayed and is highlighted. The value of 0  
disables the display of message text.  
In the Rows of Separation list box, 0 is displayed and is highlighted. The value of 0  
prevents the two text displays, date/time/title text and message text, from being  
separated by blank rows.  
In the Display Time text entry box, 0 is displayed. The value of 0 allows the message  
text to be displayed for an indefinite period of time or until it is overwritten.  
Retrieving Current Formatting: If the current formatting settings are not displayed in the  
Sample Display screen and are not shown in the Format, Rows To Display, Rows of

APPENDIX A – APPLICATIONS  
The MDA can be used in several different applications. Note that, as illustrated in some of  
the applications below, a maximum of 16 MDAs can be daisy-chained. When more than 16  
MDAs are required, a CM9760-CDU-T must be used.  
Figure 37 illustrates a simple system configuration of the MDA.  
Figure 38 illustrates a master MDA unit, MDA 1, connected to 63 MDA slave units:  
MDA 2 to MDA 64. The slave units accept the master time and date from MDA 1,  
which functions as the master clock. (An MDA functions as the master clock when unit  
ID DIP switch 8 is set to the ON position. An MDA functions in slave mode when unit  
ID DIP switch 8 is in the OFF position, which is the default setting.)  
As illustrated in Figure 38, the CM9760-CDU-T must be used when an MDA functions  
as the master clock time and date generator for more than 16 MDAs. In the illustration,  
note the following:  
The RS-422 COM 1 port of the master MDA unit (MDA 1) connects to the RS-422  
IN data port of the CM9760-CDU-T.  
The first RS-422 output of the CDU-T connects to the RS-422 COM 1 port of the  
first MDA in a chain of 16 MDAs (MDA 2 to MDA 17).  
The second output of the CDU-T connects to the second chain of 16 MDAs  
(MDA 18 to MDA 33).  
The third output of the CDU-T connects to the third chain of 16 MDAs (MDA 34 to  
MDA 49).  
The fourth output of the CDU-T connects to a chain of 15 MDAs (MDA 50 to  
MDA 64).  
In addition, note that RS-422 shielded twisted pair cable is used to connect each  
output of the CDU-T to a wall block for connection to the COM 1 port of the first MDA  
in each chain.  
Figure 39 illustrates a PC connected to a chain of 16 MDA units (MDA 1 to MDA 16).  
In this application, the PC is used to program the 16 MDA units.  
Figure 40 illustrates a PC connected to 64 MDA units: MDA 1 to MDA 64. In this  
application, the PC is used to program the 64 MDA units. The Pelco PV130  
RS-232/422 converter provides an electrical interface between RS-232 and RS-422  
data ports. In Figure 40, the PV130 interfaces the DB9 RS-232 port of the PC to a wall  
block for connection to the RS-422 IN port of the CM9760-CDU-T. (Note that the  
PV130 RS-232/422 converter eliminates the need to change the internal DIP switch  
settings of the MDA COM port to RS-232 for communication with the PC.) A plug-in  
power supply allows the PV130 to communicate serial port data over wire pairs for  
distances up to 4,000 feet (1,219 m) on the RS-422 side.  
Each of the first four outputs of the CDU-T connects to a chain of 16 MDAs (MDA 1 to  
MDA 16, MDA 17 to MDA 32, MDA 33 to MDA 48, and MDA 49 to MDA 64).  
Figure 41 illustrates a CM9760-CC1 connected to a chain of 16 MDA units (MDA 1 to  
MDA 16). An RS-422 output of the CC1 connects to the RS-422 COM 1 port of the first  
MDA in the chain. MDA 1 to MDA 16 accept the master time and date from the  
CM9760-CC1; therefore, the MDAs must be set to slave mode.  
Figure 42 illustrates a CM9760-CC1 connected to 64 MDA units: MDA 1 to MDA 64.  
An RS-422 output of the CC1 connects to the RS-422 IN data port of the CM9760-  
CDU-T. Each of the first four outputs of the CDU-T connects to a chain of 16 MDAs  
(MDA 1 to MDA 16, MDA 17 to MDA 32, MDA 33 to MDA 48, and MDA 49 to MDA 64).  
MDA 1 to MDA 64 accept the master time and date from the CM9760-CC1; therefore,  
the MDAs must be set to slave mode.  
Figure 43 illustrates an MDA connected to multiplexers.

NOTE: As illustrated in  
Figures 45 and 46, the MDA  
can be used with Coaxitron  
products such as the  
Figure 44 illustrates a non-Coaxitron setup that includes an MDA connected to a 9760  
keyboard, CM9760-CC1 CPU, and CM9760-MXB matrix bay. The MDA accepts the  
master time and date from the CM9760-CC1; therefore, the MDA must be set to slave  
mode.  
CM9760-CXTA, CM6800,  
and CM6700. Note that the  
MDA must be placed after  
the Coaxitron equipment. If  
the MDA is placed incor-  
rectly, camera control may  
be adversely affected.  
Figure 45 illustrates a Coaxitron setup that includes a System 9760 connected to an  
MDA. The MDA accepts the master time and date from the CM9760-CC1; therefore,  
the MDA must be set to slave mode.  
Figure 46 illustrates a CM6800 connected to an MDA. The MDA accepts the master  
time and date from the CM6800; therefore, the MDA must be set to slave mode. (The  
MDA can also accept the master time and date from the CM6700.)  
Figure 47 illustrates an MDA that accepts message text from third-party equipment.  
The third-party equipment connects to a COM port (COM 1 or COM 2) of the MDA  
using the RS-232 or RS-422 communication standard. For cabling requirements, refer  
to the Data Connections section of this manual. For information about COM port DIP  
switch settings required for RS-232 and RS-422 communication, refer to the Commu-  
nication Ports Setup section of this manual. For a wiring diagram of the MDA using  
RS-232 communication, refer to the Connecting the MDA to an External PC section of  
this manual. For information about MDA COM port pinouts using RS-422 communica-  
tion, refer to Table D in this manual. Note that when connecting the MDA to third-party  
equipment using RS-422 communication, TX+ must connect to RX+ and TX- must  
connect to RX-. For information about support of message text insertion by the MDA,  
refer to the Set Message Text section of this manual and to Appendix C.

APPENDIX B – SUPPORTED TITLE AND MESSAGE TEXT  
CHARACTERS  
The CM9760-MDA supports the characters listed in Table G for display of title and message  
text. If a character is not supported, the CM9760-MDA PC Setup program on a PC blocks  
entry of the character in title and message lines. If you enter a title in the CM9760-MDA  
SETUP dialog box or enter a message in the Message Text Editing dialog box and type a  
character that is not supported, the CM9760-MDA PC Setup program prevents entry of the  
character.

[A0][CB][09][Unit ID][Channel][Message Text (1-24  
characters)][AF][Checksum]  
*The MDA response to the message text query command is the command using function  
byte 01.  
The MDA response to the message format query command is the command using  
function byte 06.  
Note the following about the commands shown in Table H:  
Data within brackets is expressed as hexadecimal data. Brackets are not part of the  
commands—the brackets are used to separate the various parts of the command to  
provide ease of readability.  
First four bytes of each command are as follows:  
[A0][CB][function byte][Unit ID]  
where:  
[A0] and [CB] = 2-byte header information  
[function byte] = [00] to [09], which determines the command function  
[Unit ID] = [00] to [63] in packed binary code decimal (BCD) format, which defines  
the Unit ID number of the MDA

Optional command parameters depend on the function byte ([00] to [09]) and include  
the following:  
[Channel] = [00] to [15] in packed BCD format, which defines the channel number  
of the MDA unit  
[Row] = [01] to [05] in packed BCD format, which defines the row number in  
which message text is to be set or cleared  
[Message Text] = specifies the message text to be displayed:  
1 to 24 characters for one line of message text  
4 to 124 characters, where:  
Minimum = 4 message separator bytes ([7F][7F][7F][7F]) and no message  
text  
Maximum = 124 bytes: 5 messages containing 24 characters each (120  
message bytes) plus 4 message separator bytes ([7F][7F][7F][7F])  
[Format] = [00] or [01], where:  
[00] = displays message text below the title/time/date text  
[01] = displays message text above the title/time/date text  
[Row-Separation] = [00] to [28], which defines the number of blank rows  
separating the title/time/date text and the message text displays  
[Rows-to-Display/Scroll] = [00] to [05], which defines the number of message text  
lines to be displayed. Also defines the number of message text lines to be  
scrolled.  
[High Message Time][Low Message Time] = Message time bytes that are  
transmitted and received in packed BCD format. The message time bytes define  
the number of seconds that the message text is to be displayed. The maximum  
display time-out is 9,999 seconds. A display time-out of 0 seconds allows the text  
to be displayed indefinitely or until overwritten.  
Last two bytes of each command are as follows:  
[AF][Checksum]  
where:  
[AF] = signals end of the command  
[Checksum] = exclusive-or of all other bytes in the command
