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, as shown at right:
Tx to Tx
z
Rx to Rx
z
(ground) to
z
NOTE: For information about controlling display devices with RS-232 commands,
please refer to the user guide of that device.
IR signals
IR signals are one-way (from control device to the IR emitter that
broadcasts 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, as shown at right:
The Signal (S), from the control device to Tx of the transmitter.
z
The ground (G) of the control device is connected to the
z
ground ( ) of the transmitter.
The Tx of the receiver to the S of the IR emitter.
z
The ground ( ) of the receiver to the ground (G) of the IR emitter.
