CONNECTION
The Simplicity®LINC has 2 ports, one for connection to the BAS network (BACnet) and one to the Simplicity® board (Modbus).
BACNET NETWORK
The only connection required in the field is to the BACnet (BAS) network.
NOTE: Proper termination and grounding of the shields must be observed.
DIP switches
A Device Instance (DE) Modifier is used by the Simplicity®LINC and defaulted to 230. The combination of the DE Modifier and the default DIP switch setting creates a default DE of 23001.
The default Unit Name is YORK_RTU.

MODBUS CONNECTION
The UP device communicates with the Simplicity®LINC using the Modbus RTU protocol on an RS485 connection. Connection and addressing of the UP product is completed at the factory. No further adjustment should be done.
The default Simplicity® board address is 1. Do not engage the Address button on the Simplicity® board. This changes the address and causes a Modbus communication failure.
If a problem arises with the Simplicity®LINC or a parameter not exposed by the Simplicity®LINC requires modification, the UP controller software can be manipulated using a Microsoft©
SOFTWARE SETUP
The control sequence is managed by the Simplicity® controller. The data points on these systems are mapped to standard AV and BV BACnet Objects. As a preconfigured application, no configuration is necessary in the Simplicity®LINC Gateway.
