4.1 COMPUTER VIDEO INPUT (VGA-

COMPATIBLE 15-PIN HD CONNECTOR)

The two 15-pin HD inputs allow the connections
of two computers to the interface using cables
with a 15-pin HD connector on the interface end
and a matching connector on the computer end.
This 15-pin HD connector allows greater
flexibility and versatility from the VA6831FC. All
ID pins are passed through for proper boot up
mode. Several computers like the PC, MAC,
SUN, and SGI can be attached using the proper
cables as described in Section 8 - Accessories.

4.2 LOCAL MONITOR OUTPUT (15-PIN HD

CONNECTOR)

Each of the inputs has a local monitor output
through a 15-pin HD female connector. These
outputs allow the connections of a local monitor
up to 12 feet away from the interface.

These are fully buffered outputs, eliminating
reflections often caused by “Y” type monitor
breakout cables. It is not necessary to terminate
the unused output. The output is VGA
compatible, but can also be used to transmit
signals to other types of local monitors using the
provided Altinex adapter cables such as VGA,
MAC, SUN, SGI, or RGB.

PIN
