WIRING
In addition to control using the included IR remote control, you can use either an external
switch or your computer to control the screen. A convenient RJ45 connector allows you to
easily wire your switch or computer to the screen.
For a wall switch, wire the switch (not included) to pins 4-5 and 7-8 of an RJ45 plug (not
included). For RS-232 or RS-485 control, wire a DB-9 plug (not included) to pins 1 and 2 an
RJ45 plug (not included). The following table and images illustrate the proper connections.
Note that you should not wire both a switch and a DB-9 plug to the same RJ45 plug.
