Introduction
The Cat. No. 1403-NSC Smart Communications Card is
a microprocessor-controlled dual-port communication
plug-in accessory to the Powermonitor II Master Module.
This accessory provides the Powermonitor II with two
active communication ports which can be used at the
same time. Required configuration parameters (R I/O
rack address, baud rates, etc.) are provided by
configuring the Master Module. One port is dedicated to
the Allen-Bradley PLC

R I/O network and the other
port is software configurable for either EIA Standards
RS-232C or RS-485. (There are no hardware options to
configure when the card is installed.)
