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 3-18.
Figure 3-18. External IR Receiver Connection
Connecting to AC Power Projector/DHD Controller: Plug the female end of one power cord into the AC
receptacle on the rear of the VX-22d (AC 100V ~ 240V). Then, connect the other end to
your AC power source.
Similarly connect the DHD Controller to a nearby AC outlet.
AutoScope Lens Motor: With AutoScope-equipped projectors, an additional power
cord is provided for the lens motor. Plug the female end of the AC power cord into the AC
input on the rear of the lens motor assembly. Connect the other end to a 110
VAC power
source.
➤
When an external IR receiver is connected to the wired IR input, the
built-in IR sensor on the DHD Controller is disabled.
