RS-232 signals
RS-232 signals are bidirectional – signals
pass from the control device and
replies return from the remote device.
To connect the control device to the
transmitter or the receiver to the remote
device, make the following connections:
Tx is connected to Tx. •
Rx is connected to Rx. •
Ground ( • ) is connected to ground.
N For information about controlling display devices with
RS-232 commands, please refer to the user's manual of
that device.
IR signals
IR signals are one-way (from control device
to the IR emitter bug that will broadcast the
IR signal remotely). There are no responses
and no requirement for a reverse pathway.
To connect the control device to the
transmitter or the receiver to the IR emitter,
make the following connections:
The Signal (S), from the control device, is •
connected to Tx of the transmitter.
The ground (G) of the control device is
•
connected to the ground ( ) of the transmitter.
The Tx of the receiver is connected to the S of the IR emitter.
•
The ground of the receiver is connected to the ground of the •
IR emitter.
