Configuration Port Connector
The configuration port is the 9-pin D-Subminiature male connector on the end of
the BridgeWay. The connector has a standard RS-232 DTE pin configuration. The
connections to be made as shown below.
The BridgeWay is connected to a PC for configuration using a null-modem cable.
A null-modem cable has pins 2 and 3 swapped so that the PC’s Transmit line is
connected to the BridgeWay’s Receive line, and the PC’s Receive line is con-
nected to the BridgeWay’s Transmit line.
Note: The BridgeWay does not make use of the modem control signals specified
for a DTE connector. Connecting the module through devices, such as isolation
modules, which assume control of these lines may cause the BWConfig commu-
nications to be unreliable.
