How to Use External Control (cont.) 22

Using the MAKE/TRIG. system

The RS-485 IN terminal is configured as follows. You can assign the functions to each pin terminal by setting “REMOTE SYSTEM” (see “PORT F1 – PORT F5” on page 15).

	Pin No.	Pin name	Pin No.	Pin name
	1	PORT F1	5	PORT F5
	2	PORT F2	6	ENABLE
	3	PORT F3	7	NC
This is a female terminal.	4	PORT F4	8	GND

To assign the functions to the pin terminals

For the operation procedure, see page 12.

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	Opening	Short-circuiting
VIDEO	Changes the input to VIDEO.	Invalid	Valid
RGB	Changes the input to RGB.	Invalid	Valid
DVI	Changes the input to DVI.	Invalid	Valid
POWER	Turns on/off the monitor.	Power on	Power off (standby)
ASPECT	Changes the aspect ratio.	REGULAR	FULL
MUTING	Turns off or resumes the volume.	Muting off	Muting on
PIP	Turns on/off the PIP mode (see page 11).	Invalid	Valid
PBP	Turns on/off the PBP mode (see page 11).	Invalid	Valid
– – –	No function	—	—

NOTE

•You cannot assign the same function to different 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 changing input, only one terminal must be short-circuited. (Other terminals must be opened.)

•When switching PIP and PBP modes, open the mode which has been short-circuited before short-circuiting 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.
