Single IP LAN with daisy-chained RS232

In this example, the host PC is connected to the first display via LAN. Subsequent displays are connected together
using RS232 daisy-chaining. Each display on a daisy-chain must have a unique MONITOR ID.
The first display is configured to use LAN as the EXTERNAL CONTROL on the OSD. The other displays are
configured to use RS232 as the EXTERNAL CONTROL on the OSD. The RS232 OUT on the first display is
connected to the RS232 IN on the next display.
Since communications to all of the displays is routed through the first display, the software is configured to use the
IP address of the first display for each display. The first display will translate commands via LAN to the RS232 OUT
to be received by the other displays in the video wall.
