RS-232C IN, OUT, and LAN

In this example, the host PC is connected to the rst display via LAN. Subsequent displays are connected together using

RS232 daisy-chaining. Each display on a daisy-chain must have a unique MONITOR ID.

Important: The rst display is congured to use LAN as the EXTERNAL CONTROL on the OSD. The other displays are

congured to use RS232 as the EXTERNAL CONTROL on the OSD. The RS232 OUT on the rst display is connected to the

RS232 IN on the next display.

Since communications to all of the displays is routed through the rst display, the software uses only the IP address of

the rst display. The rst display then translates commands received via LAN to the RS232 OUT to be received by the

other displays in the video wall.
