PWR Connector
The PWR connector (Figure D-6) supplies both positive and negative bias
power as well as multi-function signals to the DR3e Driver/Receiver Board if
the external front power option is purchased. The DR3e does not require front
panel power.
Figure D-6: Front Panel Optional DR3e PWR Connector
When installing the DR3e Driver/Receiver Board with the front panel power
option, be sure that the correctly marked power cable (inside the module) is
connected to its specific board – the cable marked DRA for the DRA board
and marked DRB for the DRB board.
