5) Ethernet: 1000Base-T connection for network connections.
At a minimum, BRIC-Link II needs a source of power, an
audio connection, and a network connection.
Audio connections on the XLR jacks are wired in the
following fashion:
1 Ground
2 Balanced Audio +
3 Balanced Audio -
With a nominal input level of 0dBu (+20 dBu full scale).
You may apply AES3 digital audio to the left I/O connectors
if dip switch #1 (Input) and #2 (output) are up.

6) Contact Closures: Four sets of contact closure Inputs
and Outputs are available on this port. Inputs can be
used to send signals to the far end of the link or trigger
connections. Outputs can be used to trigger remote
control gear like automation equipment.
7) Serial: Connection for asynchronous ancillary data.
8) Power: 4 Pin connector for attachment of Comrex
approved DC power adapter. Requires 24V DC @ 1A.
9) USB: Used to attach a USB to Ethernet adapter, for
using dual networks via CrossLock.
Audio inputs should be
applied and levels checked
with dip switch #4 down. If
the audio indicators are
showing red, it indicates
the level is approaching
or reaching clipping stage.
It is OK for audio levels to
reach the yellow stage often.
The Ethernet connector is a standard 1000Base-T.
A normal patch cord, such as used for a computer,
should be connected here.
