Input cable lengths
To obtain the highest transmission rate of 330 MHz (dual link) or
165 MHz (single link), the maximum input cable length for the
DVI DL 101 is 200' (61 m). Longer cables may be used at lower
rates. High quality cable can increase the distance and rate of
transmission. However, the achievable distance and speed are
also contingent on the sensitivity of the input source and the
display device.
Dual and single link modes
The DVI DL 101 can operate in dual link mode or single link
mode; dual link DVI is backwards compatible with single link
DVI.
N Operation in dual link mode requires that both the source
and the display support dual link DVI signals. If they
do not, the DVI DL 101 can operate in only single link
mode.
The table below shows the maximum cable lengths
recommended for each resolution, in dual link mode and single
link mode.
N Avoid using couplers and adapters between cables, as
this can result in signal degradation.

DVI output connector — Plug the cable from a DVI output
device into this female dual link DVI-I connector, following
the pin configuration shown in the table on page 2-12. Output
signals will be digital only. The maximum output cable length is
16.4' (5 m). Pin 14 provides +5 VDC power.
N Dual link DVI cables must be used for dual link DVI
signals. If a single link DVI cable is used, only single
link DVI signals are possible.
d
Power connector — Plug the external 12 V power supply
(provided with the unit) into this 2-pole captive screw connector.
The figure on the next page shows how to wire the connector.
