an RS-232C cable.
Or, using a CAT5 cable, connect the RS-232C connector of the computer to the CAT5 IN connector of the Master monitor via
the CAT5 Tx BOX.
2. Assign a monitor ID to each multi-connected MDT421S using MONITOR ID. (See step 2 on page 33.)

By connecting multiple MDT421S monitors using RS-232C cables, you can control any one monitor or all the monitors by one
remote controller.
1. Assign arbitrary ID number to each of multi-connected MDT421S monitors using MONITOR ID.
ID numbers 1 to 26 are selectable.
It is recommended to assign sequential ID numbers from 1 and up.
2. The remote control mode of the fi rst MDT421S monitor is set to PRIMARY and those of the other monitors are set to
SECONDARY.
3. When you direct the remote controller at the remote control signal sensor of the PRIMARY monitor and press the DISPLAY
button on the remote controller, the ID selection OSD appears at the upper left of the screen.

ID No. :2
Select the ID number of the monitor you want to control using the +/- button
on the remote controller.
The ID of the monitor you want to control is displayed at the upper left of its screen.
By selecting ALL, you can control all the multi-connected monitors.

4. Direct the remote controller at the remote control signal sensor of the PRIMARY monitor.
OSD appears on the monitor having the ID number you selected.
NOTE:
When the ID selection OSD is being displayed on the PRIMARY monitor, press the DISPLAY button on the remote controller
again to cancel the ID selection OSD and then control the monitor you selected.
NOTE:
If you set the remote control mode wrongly and remote control operation becomes unavailable, press any button on the control
panel of the monitor to display the OSD screen and change the remote control mode using ADVANCED OPTION. By pressing
and holding down the DISPLAY button on the remote control for 5 seconds or longer, the remote control mode is initialized to
