5.8 Cable
Connections
The application ports on the MVI56-DNP module support RS-232, RS-422, and
RS-485 interfaces. Please ensure that the jumpers are set correctly for the type
of interface you are using.
Note for modules with RS-232 connection to a radio or modem:
Some radios or modems
require hardware handshaking (control and monitoring of modem signal lines) on the RTS and CTS
lines of an RS-232 connection. Enable this by setting the
UseCTS
parameter in the module
configuration to
1
.
5.8.1 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 pinout for communications on this port is shown in the
following diagram.
5.8.2 RS-232
Application
Port(s)
When the RS-232 interface is selected, the use of hardware handshaking
(control and monitoring of modem signal lines) is user definable. If no hardware
handshaking will be used, here are the cable pinouts to connect to the port.
