Use Modems with Micro800
Controllers
Serial modems can be used with the Micro830, Micro850, and Micro870
controllers.
Making a DF1 Point-to-Point Connection
You can connect the Micro830, Micro850, and Micro870 programmable
controller to your serial modem using an Allen-Bradley null modem serial
cable (1761-CBL-PM02) to the controller’s embedded serial port together with a
9-pin null modem adapter – a null modem with a null modem ad
apter is
equivalent to a modem cable. The recommended protocol for this
configuration i
s CIP Serial.
Construct Your Own Modem Cable
If you construct your own modem cable, the maximum cable length is 15.24 m
(50 ft) with a 25-pin or 9-pin connector. See the following typical pinout for
constructing a straight-through cable:

Micro850 controller
with

(Address 0)
CompactBlock LDX I/O
(Address 2)
The user can use Connected Components Workbench software to configure
the PowerFlex drives.

IMPORTANT
Micro800 controllers do not support more than one hop (for example, from
EtherNet/IP CIP Serial EtherNet/IP).
