DDTX/DDRX DVI • Installation

Description and Installation

Description

The Direct Digital Transmitter (DDTX) half of the DDTX/DDRX

DVI pair accepts a Digital Visual Interface (DVI) signal or a

Digital Flat Panel (DFP) signal (with a DFP-to-DVI adapter) from

any device that outputs digital video. The DDTX creates

proprietary digital signals, and outputs the signals over coaxial

cable to the Direct Digital Receiver (DDRX) half of the pair. The

transmitter also sends and receives the bidirectional Display Data

Channel (DDC) signals on a separate set of connectors. The

receiver converts the digital and DDC signals back to DVI video,

and outputs it for use by a compatible display device. The

maximum separation between the DDTX and DDRX depends on

the cables used:

• Maximum 150’ (45.72 meters) — This limit applies to systems

using cable of the quality of Extron High Resolution cable.

• Maximum 330’ (100.58 meters) — This limit applies to systems

using cable of the quality of Extron Super High Resolution

cable.

The DDTX is rack mountable and has an internal switching

power supply.

The DDRX comes with its own external desktop power supply

and a detachable bracket for mounting the unit to a projector

mount or other convenient surface. The DDRX is also through-

or under-desk mountable with optional mounting kits.

Installation

1. Power off the computer and its local monitor.

2. For optional rack mounting, mount the DDTX on one side

of a 19" 1U Universal Rack Shelf (Extron part #60-190-01)

(figure 1).

Installation 3. a. If feet were previously installed on the bottom of the case, remove them. b. Mount the DDTX on the rack shelf, using two 4-40 x 1/8 screws in opposite (diagonal) corners to secure the case to the shelf. For optional bracket mounting, attach the included mounting bracket to the DDRX using the 3 bracket screws. The DDRX can then be attached to a projector mount or some other secure surface by inserting the mounting screw through the bracket’s slotted hole (figure 2). 6.

Installation Comm-Link cable and two 3.5 mm captive screw connectors. Wire the connectors as shown in figure 5. Paired Set The DDTX and DDRX are a paired set, sharing a common serial number. Each half is specifically tailored to work with the other. Ensure that identically serialnumbered halves are kept together and are not intermixed with units from different sets. Units from different sets are not guaranteed to work together.

Installation Operation Troubleshooting DVI/DFP signals run at a very high frequency and are especially susceptible to bad video connections, too many adapters, or too long cables. To avoid the loss of an image or image jitter, follow these guidelines: • • • • Do not exceed 16.4 feet (5 meters) on the output of the DDRX. Use only cable designed for DVI signals. Limit or avoid the use of adapters. Use only approved DVI/DFP connectors. Enclosure type .............................. Enclosure dimensions ......
