How to Use External Control
7 Using the MAKE/TRIG. system
The RS-485 IN terminal is confi gured as follows. You can assign the functions to each pin terminal by setting "REMOTE
SYSTEM" (see "PORT F1 – PORT F5" on page 25).
1 2 3 4 5 6 7 8
This is a female terminal.
To assign the functions to the pin terminals
For the operation procedure, see page 17.
1. Select "REMOTE SYSTEM" on the set-up menu.
2. Set "CNT. RJ45 IN" to "SET."
3. Select a pin name ("PORT F1" – "PORT F5") which you want to assign a function, and then select the function you
want to assign.
• For functions which can be assigned, see the table below.
Functions controlled by MAKE/TRIG. system
Display Functions to be controlled
INP. A Changes the input to Input A.
INP. B Changes the input to Input B.
INP. C Changes the input to Input C.
INP. D Changes the input to Input D.
INP. E Changes the input to Input E.
INP. F Changes the input to Input F.
POWER Turns on/off the monitor.
ASPECT Changes the aspect ratio.
MUTING Turns off or resumes the volume.
PIP Turns on/off the PIP mode (see page 16).
PBP Turns on/off the PBP mode (see page 16).
– – – No function
NOTE
• You cannot assign the same function to diff erent pin terminals.
• The TRIG. (trigger) system switches each function by short-circuiting for approx. 1 second.
Operation
1. Short-circuit the 6th pin terminal (External control) to the 8th pin terminal (GND) so that the monitor can be
controlled by the external control.
2. Set "CNT. RJ45 IN" of "REMOTE SYSTEM" to "MAKE" or "TRIG." on the set-up menu.
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 "TRIG." (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.
NOTE
• When controlling INP. A/B/C/D/E/F, only one terminal must be short-circuited. (Other terminals must be opened.)
• When switching PIP and PBP modes, open the mode which has been shortcircuited before shortcircuiting the mode you want to make valid.
• When selecting the "TRIG." (trigger) system, you can operate only one function at a time. Operate the functions one by one.
