(Control to IR In of USB RX Cable) (Connect to IR Out of USB TX Cable)
IR blaster extension cable should plug in the IR port of USB TX cable,
and the IR receiver extension cable should plug in the IR port of USB RX
cable.
The emitter of IR blaster should as close as possible to the IR receiver
window of the signal source device.
The control signal will be better when your controller is pointed at the IR
receiver head directly.
When connected to control system, ensure the IR emitter is over against
the IR receiver’s raised side instead of its flat side.
