Introduction, cont’d
IN1508 Scaling Presentation Switcher • Introduction1-4
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:
Resolution Recommended maximum cable length
1024 x 768 75 feet
1280 x 1024 60 feet
1600 x 1200 35 feet
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
3.5 mm 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.
