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). This is a female terminal. Pin No. 1 2 3 4 Pin name PORT F1 PORT F2 PORT F3 PORT F4 Pin No. 5 6 7 8 Pin name PORT F5 ENABLE NC 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. 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. Functions controlled by MAKE/TRIG. system Display Functions to be controlled VIDEO Changes the input to VIDEO. RGB Changes the input to RGB. DVI Changes the input to DVI. 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 11). PBP Turns on/off the PBP mode (see page 11). - - - No function Opening Invalid Invalid Invalid Power on REGULAR Muting off Invalid Invalid - Short-circuiting Valid Valid Valid Power off (standby) FULL Muting on Valid Valid - 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.
