14.6 Configuring Serial Communication Parameters for Athena
Plus Protocol
14.6.1 Introduction
The items that appear on the SerLSerL (serial) menu in controllers that support Athena Plus
protocol are different from the SerLSerL menu items displayed if the controller supports the
MODBUS protocol. The Multi-Comm User’s Guide contains more information about
configuring a controller to communicate with the Multi-Comm host over an RS-232 or
RS-485 network. We recommend that you consult that manual before setting up your
Multi-Comm network and configuring these communication parameters.

manual provided with the controller.
