APPENDIX C: UDB Settings

Appendix C. UDB Settings

The single-port serial transmitters and single-port and dual daisychainable serial
receivers contain an internal Universal Digital Board (UDB) that can be
reconfigured from its simplex operation default setting for bidirectional 
operation.  

The UDB hardware configuration is done via jumper settings. These jumpers are
used to route signals to the interface port(s) for the DB9 connector and to
configure the transceiver for RS-485 operation.

To access the UDB on these transmitter and receivers:

1. Make sure the unit is powered OFF. 

2. If necessary, unplug all cables to the unit.

3. Unscrew the top screw as well as the two set screws in the DB9 connector. Lift

the cover off. 

For reference Table C-1 shows the input/output jumper configuration for the DB9
connector as it’s currently pinned on the board.
