Corporation NetLinx Integrated Controllers Hardware Reference Guide

Introduction

NI-2100, NI-3100, NI-4100 Hardware Reference Guide
These NI Controllers use a combination lithium battery and clock crystal package called a Timekeeper.
Only one Timekeeper unit is installed within a given NI controller. The battery can be expected to have
up to 3 years of usable life under very adverse conditions. Actual life is appreciably longer under normal
operating conditions.
 This calculation is based on storing the unit without power in 50° C (120° F) temperature until
battery levels are no longer acceptable.
 The part number for a replacement battery is 57-0032.
NI-2100 Specifications
The NI-2100 (FIG. 1) provides support for 3 RS-232/RS-422/RS-485 Ports, 4 IR/Serial Output ports, 4
Digital Input/Output ports, and 4 Relays. The NI-2100 can be upgraded to provide
1 ICSHub and 2 ICSNet ports by either installing the optional ICSNet daughter card (FG2105-10) or
purchasing this upgrade as an included feature of the NI-2100 Kit (FG2105-14).
