NetLinx Integrated Controllers
Introduction
NetLinx Integrated Master Controllers can be programmed to control RS-232/422/485, Relay, IR/
Serial, and Input/Output devices through the use of both the NetLinx programming language and
the NetLinx Studio application (version 2.2 or higher). Another key feature of this products is the
ability to easily access the configuration switches without having to remove a
cover plate.
The NI series of 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.
