This board is an adapter for the Daniels chassis backplane to allow using external repeater controllers such as our PI-REPEATER-2X dual port controller system.
The board mates directly with the system interface as shown and is held in place with the connector and 2 screws/spacers to prevent creating a lever arm that could break the connectors.
The high density connector is brought out to 2@ DSUB-9 connectors that follow a common pinout so all you will need is basic 9/10 conductor DSUB-9 cables with a 1:1 pinout to connect up to your desired controller.
A 14 pin Header allows selection of a number of audio configurations for both transmit and receive audio on each port. Please refer to the schematic for details.
