Standard DVI cable

DVI/DFP signals run at a very high frequency and are especially prone to bad video connections, too many adapters, or excessive cable length. To avoid the loss of an image or jitter, follow these guidelines:

Do not exceed 16.4 feet (5 meters) on the switcher’s input when using standard DVI cables.

Extron’s IN9700 extension cable can be used to extend the length of the input cable. See “IN9700 cable”, below.

Only use an input cable specifically designed for DVI signals.

Limit or avoid the use of adapters.

Use only approved DVI/HDMI connectors.

Use only cables specifically intended for DVI or HDMI interfaces. Use of non-DVI or non-HDMI cables or modified cables can cause the switcher to be unable to receive the DVI input.

IN9700 cable

Extron’s IN9700 extension cable can be used to stretch the length of the input cable, so long as no adapters are used in the cable run. Use the following lengths as a guideline:

Features

Inputs —

Video inputs — The switcher switches among:

Two fully-configurable RGB video inputs on 15-pin HD connectors

One HDTV component video, interlaced component video, or progressive scan video on three BNC connectors

Two S-video inputs on 4-pin mini-DIN connectors

Two composite video inputs on single BNC connectors.

One single link of DVI-D on a DVI connector with EDID emulation

Audio inputs — The switcher switches among eight unbalanced stereo audio inputs, five inputs on left and right RCA connectors and three inputs on

3.5mm mini stereo jacks. Inputs can come from sources such as a VCR, DVD player, computer audio card, or other audio device that outputs a stereo line-level signal.

Outputs —

Video outputs — The IN1508 outputs scaled video signals as progressive RGBHV, RGBS, RGsB, or component video, from 640 x 480 (VGA) up to 1600 x 1200 (UXGA), to match the optimum or native resolution of virtually any display device, on a 15-pin HD connector.

The output refresh rate is selectable as desired through the on-screen display menu. When used with LCD or DLA displays, Extron recommends the 60 Hz setting. Higher output refresh rates can be used with CRT displays to reduce flicker.
