Comrex BRIC-Link Product Manual page 15

To use AES3, the front panel DIP switches must be set appropriately. AES3 input connections can be at 32, 44.1 or
48 kHz. The front panel DIP switches must be set appropriately. On the BRIC-Link, the output audio sample rate
automatically locks to the input sampling rate. If analog input is used, (or AES3 input configured and unconnected),
AES3 output is always 48 kHz.
Because BRIC-Link can encode and/or decode in stereo and mono modes, it's important to understand how the
audio inputs and outputs are handled in each mode.
InPuts
In mono encode modes, BRIC-Link uses the left channel of the stereo input for delivery to the mono encoder.
outPuts
In stereo decoder modes, left and right channels are delivered to the output connectors separately. In mono
decoder modes, mono audio is delivered to both left and right output connectors.
PInouts - seRIaL PoRt
The Serial Port is pinned to match serial connections on older Macintosh computers, so commercially available
adapter cables should have the proper pinning.
PInouts - ContaCt CLosuRes
Contact closures are available via the 9-pin mini-DIN connector on the rear panel of the BRIC-Link. Inputs are
triggered by shorting the respective input to Pin 9. Outputs consist of an open collector circuit which, when
inactive, will offer a high-impedance path to Pin 9 and, when active, will offer a low impedance path to Pin 9. These
outputs are capable of sinking up to 200 mA at a voltage up to 12 V.
