The return character is the standard 13 decimal or 0x0D hex.
The numeric values for both the time and date commands must be in hexadecimal format as
shown below:
For example, to set the time to 23:56:00 send the following command:
!TIME 17 38 0 [return char]
To set the Date to 21 January 2006 send the following commands:
!DATE 1 15 6 [return char]
Connecting Multiple Units
If there is only one video processor in the system, then the commands may be issued without
the Unit ID prefix. This prefix is necessary if multiple video processors are connected in a
daisy chain configuration to allow communication from a single PC/Terminal (see Figure 2.2
above). You set this prefix in the SYSTEM SETTINGS menu by configuring the UNIT ID
parameter.
You can address a particular unit directly by using the !ID command followed by the UNIT ID
number followed by the command. The UNIT ID number must contain three digits, therefore
the UNIT ID for unit number 1 is 001 and the UNIT ID for unit number twenty is 020.
The format of the command in a multiple unit configuration is:
!ID XXX CMD YYY
where:
!ID
– is the Unit ID Address Command.
XXX
– is the UNIT ID for the appropriate unit. This number must have three digits to match
a valid UNIT ID.
CMD
– is the command for the unit.
YYY
– is the parameter for the preceding command, if necessary.
If a unit with a matching ID is found it replies with the “>” character followed by a return
message.
For example, to set the Date to 21 January 2006 on Unit 012 send the following command:
!ID 012 !DATE 1 15 6 [return char]
Displaying a UNIT ID
To display the Unit ID on screen send the command
!UI 1
. Use this command to debug
commands. To turn off the UNIT ID display send the command
!UI 0
.
Broadcasting Commands to all Video Processors
To send a broadcast to all units in the chain use the UNIT ID of
FFF
. For example, to set the
time on all units to 23:56:00:
!ID FFF !TIME 17 38 0 [return char]
Hours: 0x00 to 0x17
Minutes: 0x00 to 0x3B
Seconds: 0x00 to 0x3B
Month: 0x01 to 0x0C
Day: 0x1 to 0x1F
Year: 0x00 to 0x63 (2000 to 2099)
