Connections to the
VX-22d and DHD
Controller
Proceed as follows to connect the DHD Controller to the VX-22d, your video sources,
external controller(s) – if present – and AC power.
When connecting your equipment:
• Turn off all equipment before making any connections.
• Use the correct signal cables for each source.
• Ensure that the cables are securely connected. Tighten the thumbscrews on
connectors that have them.
Connector Panel Access To access the connector panel, pull firmly on the cable access cover to open it.
Connecting the DHD
Controller to the VX-22d
The VX-22d is designed to receive only digital input signals directly from the companion
DHD Controller/Processor. All signal sources should be connected to the appropriate
inputs on the rear panel of the controller. The signal from the controller is then output to
the VX-22d projector through a DVI-DL (dual-link) cable.
Use a Runco DVI Dual-Link (DVI-DL) cable to connect the output of the DHD Controller to
the input of the VX-22d; see
Figure 3-7.

You CANNOT connect a signal source with DVI output directly to
the VX-22d. It MUST be routed through the DHD Controller for
proper operation.
