Notes on IR Carrier Signals
When an IR carrier frequency is passed through from the Sender unit to the Receiver unit,
or from the Receiver unit to the Sender unit, the carrier signal is not renewed. Any carrier
frequency between 30 kHz and 60 kHz is natively passed through.
If the IR carrier signal is stripped at the Sender unit and added at the Receiver unit (or vice
versa), then the carrier signal can be set to 38 kHz, 47 kHz, or 56 kHz.
To set the carrier signal frequency on the Sender unit, use DIP switches 9 and 10 on the
Sender unit. To set the carrier signal frequency on the Receiver unit, use DIP switches 5
and 6 on the Receiver unit.
Stripping the IR carrier signal is commonly used when directly connecting an IR cable from
the output of one device to the input on another IR device.
