JVC GM-F420S, GM-F470S, GM-F520S How to Use External Control

This is a female terminal.

How to Use External Control (cont.)

The RS-485 IN terminal is configured as follows. You can assign the functions to each pin ter minal by setting

“REMOTE SYSTEM” (see “PORT F1 – PORT F5” on page 15).

Pin No. Pin name Pin No. Pin name

1PORT F1 5PORT F5

2PORT F2 6ENABLE

3PORT F3 7NC

4PORT F4 8GND

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.

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.
