Connecting an External IR
Receiver to the DHD
Controller
If infrared signals from the remote control cannot reach the DHD Controller due to
excessive distance or obstructions such as walls or cabinet doors, you can connect an
external IR receiver to the WIRED REMOTE input on the DHD Controller to extend the
range of the remote control. See
Figure 3-15.

When an external IR receiver is connected to the wired IR input, the
built-in IR sensor on the DHD Controller is disabled.
