How to Use External Control
(cont.)
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 the right.
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:
1
Starting the communication: connection
command (!00BCN1Cr)
3
Selecting the Input A (!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 <Command list> on the right.
• Commands starting with “@” are status returns from the monitor.
