2 Johnson Controls Unitary Products
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 A0-A7 on the Simplicity ® LINC board allow
selection of the MAC Address. The MAC Address identifies the
Simplicity
® LINC to other devices and must be between 1 and
99. The default DIP switch setting is 1.
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.
FIGURE 2: MAC ADDRESS EXAMPLES
DIP switches B0-B3 on the Simplicity
®
LINC board allow for
selection of the BACnet transfer speed.The default speed is set
at 38.4k baud. Other speeds can be chosen as shown in Table
1.
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.
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
©
Windows-based PC with the Simplicity
®
PC software
(downloadable from the UP website). To connect the PC to the
UP controller, a FREEnet USB adaptor (Part No.
S103101967000), which is an RS232 to RS485 adapter, and
FREEnet adapter cable (S102538682000) are required and
available through SOURCE1 (Toll-free at 1-800-536-6112).
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.
