Overview

The FP-1001 is a network module for the FieldPoint system. It
provides connection to an RS-485 network using a simple ASCII
protocol.

This document provides a quick guide to installing and configuring
the FP-1001 network module. For more detailed information on
using the network module, refer to the FP-1000/1001 user manual.
For information on the ASCII protocol used by the network
module, refer to the FP-1000/1001 programmer reference manual.

DIN Rail Mounting

NOTE: Terminal bases must be connected to the network
module before applying power to the module. Do not connect
or disconnect terminal bases while power is applied to the
network module.
