3. Product Overview
3.3. Electrical Connections
3.3.1. DVI-I Connector
DA2DVI-DL provides 29 pole „digital only" DVI-I Dual-Link connectors
(only digital pins are internally connected). This way, users can plug in
any DVI connector, but keep in mind that analog signals (such as VGA
or RGBHV) are not processed.
Always use high quality DVI cable for connecting sources and displays.

DVI-DL Output
Monitor hotplug is detected on the DVI-DL OUTPUT 1 (HPD LED lights
green). After a hotplug event, the DA2DVI-DL tries to read the EDID of
the connected device.
No output reclocking is provided. If a long DVI cable is connected then
equalization and reclocking may be necessary at the receiver end of
the cable.
Fiber Cable Powering
As a special feature, the device is able to supply 500 mA current on
DDC +5V output (pin 14 on the output connectors) to power fiber
optical DVI transmitters. Standard DVI outputs or VGA cards supply
only 55 mA current on +5V output, thus unable to power directly a fiber
optical cable.
INFO: The device does not check if the connected sink (monitor,
projector or other equipment) supports hotplug or EDID signals but
outputs the input signal directly.
DVI-DL Input

The input has Dual-Link disable option, which ensures Single-Link

compatibility. Devices supporting Dual-Link output can confuse
C5
Single-Link inputs; disabling the Dual-Link TMDS channel distribution
solves this problem. For more information see
section.

Hot Plug Detect
DA2DVI-DL has no built-in cable equalization circuit. Be sure to use no
TMDS Data0-
longer than 5m cable. If there is more distance needs to be covered,
