Connecting an External IR 
Receiver to the VX-22i
If infrared signals from the remote control cannot reach the projector 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 VX-22i to extend the range of the remote 
control. See Figure 3-17. 
Figure 3-17. External IR Receiver Connection
Connecting to AC Power
Projector: Plug the female end of one power cord into the AC receptacle on the rear of 
the VX-22i (AC 100V ~ 240V). Then, connect the other end to your AC power source. 
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 VX-22i is disabled.
