ABOUT EXTERNAL CONTROL

This multi-format monitor has two external control terminals. One is the MAKE terminal, which controls the monitor by connecting the terminals with many functions to the ground (GND) terminal. The other is the RS-232C terminal, which allows the monitor to be controlled by a PC via serial communication.

Control priority is in the following order; the MAKE terminal > the RS-232C terminal > the buttons on the front panel.

Connections

Connect (short-circuit) the 15th terminal (GND) to each of the 1st through 14th terminals in the 3-lines 15-pins D-sub connector. The functions of each terminal are listed below.

*1 : OFF stands for disconnection, and ON stands for short-circuit.

*2 : Selects the area marker size from AREA MARKER (setting on the main unit) or AREA MARKER-R (setting on the remote control) setting.

*3 : The STATUS function is activated when the connection to the STATUS terminal is changed (ON to OFF, or OFF to ON). The monitor’s status is displayed for 3 seconds.

*4 : Setting REMOTE ENABLE to ON enables remote control from the MAKE terminal.

Operation

1.Set REMOTE ENABLE to ON.

2.Short-circuit or disconnect the desired terminal. Changing the Signal Input.

Changing the Signal Input

1.Set REMOTE ENABLE to ON.

2.Short-circuit the desired INPUT terminal.

3.Disconnect the INPUT terminal selected above. The signal input is actually changed after the disconnection has been completed.

NOTE : When more than two terminals are selected (short-circuited) from INPUT A through INPUT F, the signal input is not changed.

To control INPUT A through INPUT F, we recommend using the interlock switch, which turns off a switch when another switch is turned on.
