EtherNet/IP to CIP Serial
Use Modems with
Micro800 Controllers
Serial modems can be used with the Micro830 and Micro850 controllers.
Making a DF1 Point-to-Point Connection
You can connect the Micro830 and Micro850 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 adapter is
equivalent to a modem cable. The recommended protocol for this configuration
is CIP Serial.

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