Important: Only Series C or later MicroLogix 1000 discrete controllers and
all MicroLogix 1000 analog controllers support DH-485
network connections. In order to access the DH-485
functionality of the Series C or later MicroLogix 1000 discrete
and MicroLogix 1000 analog controllers, you must configure
your program to operate with these controllers. See page 18–18
for more information.

Recommended Tools
To connect a DH-485 network, you need tools to strip the shielded cable and
to attach the cable and terminators to the AIC+ Advanced Interface
Converter. We recommend the following equipment (or equivalent):
Description Part Number Manufacturer
Shielded Twisted Pair Cable #3106A or #9842 Belden
Stripping Tool 45-164 Ideal Industries
1/8 ” Slotted Screwdriver Not Applicable Not Applicable
DH-485 Communication Cable
The suggested DH-485 communication cable is either Belden #3106A or
#9842. The cable is jacketed and shielded with one or two twisted wire pairs
and a drain wire.
One pair provides a balanced signal line, and one additional wire is used for
a common reference line between all nodes on the network. The shield
reduces the effect of electrostatic noise from the industrial environment on
network communication.
