OVERVIEW
®
The Simplicity
LINC Gateway operates as a Modbus® Client
providing an interface between a BACnet® MS/TP control system
and devices that communicate using the Modbus RTU protocol.
®
The Simplicity
LINC allows monitoring and control by a third-party
BACnet Building Automation System (BAS).
®
The Simplicity
LINC is preconfigured to provide an interface to UP
products equipped with Simplicity
4/2/2008 as well as prior Simplicity
Intelli-Comfort™ controllers.
