3.2.2 RS-232
Configuration/Debug Port
This port is physically a Mini-DIN connection. A Mini-DIN 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:
3.2.3 RS-485
The RS-485 interface requires a single two or three wire cable. The Common
connection is optional and dependent on the RS-485 network. The cable required
for this interface is shown below:
Note:
Terminating resistors are generally not required on the RS-485 network, unless you are
experiencing communication problems that can be attributed to signal echoes or reflections. In this
case, install a 120-ohm terminating resistor on the RS-485 line.
