Proceed as follows to connect the VHD Controller to the Vision 120, 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.

Connecting the VHD
Controller to the Vision 120
The Vision 120 is designed to receive only digital input signals directly from the companion
VHD 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 Vision
120 projector through a DVI-DL (dual-link) cable.
Use a Vidikron DVI Dual-Link (DVI-DL) cable to connect the output of the VHD Controller to
the input of the Vision 120; see Figure 3-7.
Figure 3-10. Connecting the Vision 120 to the VHD Controller
You CANNOT connect a signal source with DVI output directly to the
Vision 120. It MUST be routed through the VHD Controller for proper
operation.
