Using the LCD with RS-232C
This LCD monitor can be controlled via personal computer
or wireless remote control using an RS-232C connection.
MONITOR ID and IR CONTROL
Using one PC or one infra-red wireless controller, up to 26
individual SC40/SC46 monitors can be controlled through a
daisy chain via RS-232C connection.
1. Connect PC and SC40/SC46.
Connect a PC’s RS-232C control output to the SC40/
SC46’s RS-232C input. You can then connect the
RS-232C output from the SC40/SC46 to another
SC40/SC46’s RS-232C input. Up to 26 monitors can be
connected using RS-232C.
2. Set Monitor ID and IR Control mode.
For proper operation, the Monitor ID should be set in
the OSD menu of each monitor that is in the chain. The
Monitor ID can be set under the “MULTI DISPLAY”
menu in the OSD. The Monitor ID number can be
set within a range from 1 to 26. No two monitors
should share the same Monitor ID number. It is
recommended to number each monitor in a daisy
chain sequentially from 1. The first monitor in the daisy
chain is designated as the primary monitor. Subsequent
monitors with the chain are secondary monitors.
In the “MULTI DISPLAY” menu on the first monitor
in the RS-232C daisy chain, set the “IR CONTROL” to
“PRIMARY”.
Set the “IR CONTROL” to “SECONDARY” on all other
monitors.
