APPLICATION GUIDE

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

®

 controllers manufactured after 

4/2/2008 as well as prior 

Simplicity

®

Elite™ and 

Simplicity

®

 with 

Intelli-Comfort™ controllers.

The 

Simplicity

®

LINC mounts inside the control panel of the UP 

unit and utilizes 24 VAC power from the unit’s control transformer. 
One port is connected to the UP controller. The other port must be 
connected to the BACnet MS/TP network.

The 

Simplicity

®

LINC Gateway is preconfigured to obtain 

operational data points from the controller and expose them on a 
BACnet MS/TP network.

NOTE: 

Not all 

Simplicity

®

 operating parameters are controlled/

monitored by the 

Simplicity

®

LINC.
