AT-OPUS-810M
IR
4-pin captive screw connectors have been
included for IR routing. Each 4-pin connect
will provide connection for 2 IR ports. All IR
ports will use a Ground ( ) and signal (S)
wire.
Pin out will be determined by the
RS-232 cable and connect as
RX (receive), TX (transmit) and
(Ground).
A 5-pin captive screw connector for control has been included. The first three terminals are RS-
232 control, the last two terminals are for IR.
IR IN is connected by a ground and
signal wire. Use with 3rd party control
systems. For easy termination, Atlona
recommends using the 2 meter IR
cable AT-LC-CS-IR-2M.
