DATA INTERFACE REMOVAL
Disconnect the AC power source from the UDC-RDS and disconnect the users data cables
from the Data Interface Module(DIM). Located on back panel of the UDC-RDS are
PORT A
and
PORT B
. Each DIM is plugged into and out of these ports through mating connectors.
Remove the top cover using a phillips screwdriver, then remove the top two screws of the
DIM. Gently pull the module from the UDC-RDS housing. It may be easier to hold the edges
of the DIM and rock the DIM back and forth as you pull the DIM out of the socket.
