Configuration Port Connector
The configuration port is the 9-pin D-Subminiature female connector on the end
of the Anybus-X. The connector has a standard RS-232 DTE pin configuration.
The connections to be made are shown in Figure 1..
The Anybus-X 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 Anybus-X’s Receive line, and the PC’s Receive line is connected
to the Anybus-X’s Transmit line.
Note:
The Anybus-X 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.
