Operation
1
Set "PARA REMO SEL" of "REMOTE SETTING" to "MAKE" or "TRIGGER" in the set-up menu.
2
Short-circuit the 7th pin terminal (external control) to the 8th pin terminal (GND) so that the monitor can be
controlled by the external control.
3
When selecting "MAKE" (make contact) system: Operate each function by short-circuiting the corresponding pin
terminal to the 8th pin terminal (GND) or opening it.
When selecting "TRIGGER" system: Operate each function by pulse control, that is short-circuiting the
corresponding pin terminal to the 8th pin terminal (GND) for about 1 second and opening it.
NOTE
• When changing the input with MAKE (make contact) system, only one pin terminal must be short-circuited. (Other pin terminals
must be opened.)
• When selecting the "TRIGGER" system, you can operate only one function at a time. Operate the functions one by one.
7 Using the serial communication
You can control the monitor from a personal computer etc. via RS-485 or RS-232C terminal.
<Communication specifications>

Cable
RS-485
A straight LAN cable
RS-232C
A straight cable with a D-sub 9-pin
connector (male for the monitor,
female for the personal computer
etc.)
<Command outline>
• To start communication, send the connection command from the personal computer etc.
• To terminate the communication, send the termination command from the personal computer etc.
Example of communication procedures
1
Starting the communication: connection command (!00BCN1Cr)
2
Monitor's status (@00BOKCr)
3
Selecting "SDI 1" input (!00BINACr)
Personal computer
4
Monitor's status (@00BOKCr)
etc.
5
Terminating the communication: termination command (!00BCN0Cr)
6
Monitor's status (@00BOKCr)
• Commands starting with "!" are operation commands from the personal computer etc. For details, see <Command list> on the
right.
• Character strings starting with "@" are status returns from the monitor.
