5.4 Cable Connections
The application ports on the MVI71-DNP module support RS-232, RS-422, and
RS-485 interfaces. Please look at the module to ensure that the jumpers are set
correctly to correspond with the type of interface you are using.
Note: When using RS-232 with radio modem applications, some radios or modems
require hardware handshaking (control and monitoring of modem signal lines). Enable
this in the configuration of the module by setting the UseCTS parameter to 1.
5.4.1 RS-232 Configuration/Debug Port
This port is physically an RJ45 connection. An RJ45 to DB-9 adapter cable is
included with the module. This port permits a PC based terminal emulation
program to view configuration and status data in the module and to control the
module. The cable for communications on this port is shown in the following
diagram:
Disabling the RSLinx Driver for the Com Port on the PC
The communication port driver in RSLinx can occasionally prevent other
applications from using the PC's COM port. If you are not able to connect to the
module's configuration/debug port using HyperTerminal or a similar terminal
emulator, follow these steps to disable the RSLinx Driver.
