• Enter the appropriate data to “xx” or “x.”
• “Cr” is 0Dh.
Using the serial communication
You can control the monitor from external control equipment (a personal computer or a dedicated controller)
via the RS-485 or RS-232C terminal.
<Communication specifications>
Input terminal Cable Terminal
specification
Communication specifications
RS-485 A straight LAN cable
See below.
Baud Rate: 4800 bps
Data Bits: 8 bits
Parity: No parity
Stop Bits: 1 bit
Flow Control: No control
Communication Code: ASCII Code
RS-232C A straight cable with a RS-232C
connector (male for the monitor,
female for the external control
equipment)
<Command outline>
When the monitor is turned on, the external control is not ready.
To start communication, send the connection command from the external control equipment.
To terminate the communication, send the termination command from the external control equipment.
Example of communication procedures:
External control
equipment
1 Starting the communication: connection
command (!00BCN1Cr)
3 Selecting the Input VIDEO (!00BINACr)
5 Terminating the communication: termination
command (!00BCN0Cr)
6 Monitor’s status (@00BOKCr)
4 Monitor’s status (@00BOKCr)
2 Monitor’s status (@00BOKCr)
• Commands starting with “!” are operation commands from the external control equipment. For details, see
<Basic command list> on the right.
• Commands starting with “@” are status returns from the monitor.
