Introduction
Crystal Vision
Installation
Silence warning and loss of input warning status are normally routed by default
to the GPI port for each channel. To prevent silence detection from raising
alarms via GPI lines please refer to the Using Card edge controls chapter.
GPI Connections
GPI lines 1 to 6 of each card are brought to one of the four remote connectors at
the rear of the FR2AV frame as follows:

Note:
Remote 1 and Remote 3 are 26 way high density ‘D’ type female
sockets and frame ground is pin 2 in each case.
Remote 2 and Remote 4 are 26 way high density ‘D’ type male plugs and
frame ground is pin 6 in each case.
Hardware configuration
This section deals with hardware jumper links to change channel gain and input
termination.
Setting channel gain
The DACA214 has four gain-set jumper links at the right hand (bottom half)
rear end of the PCB.
JL3 (Stereo 1 Left), JL4 (Stereo 1 Right), JL5 (Stereo 2 Left), and JL6 (Stereo 2 Right).
Move the links to the upward position for +18 dBu full-scale output, or to
the downward position for +24 dBu full-scale output. Other full-scale outputs
from +12 dBu to +28 dBu can be achieved by selection of these jumper links
together with adjustment of the gain calibration potentiometers, RV1 to RV4.
