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
BACnet Objects. As a preconfigured application, no
configuration is necessary in the
Simplicity
®
LINC Gateway.
FLASH MEMORY MANAGEMENT
The Flash Memory chip used in the
Simplicity
®
controllers has
a 1,000,000 write cycle rating.
To prevent premature failure of the flash memory, it should not
be written to more often than once every 10 minutes, on
average.
The default
Simplicity
®
board address is 1 and must
remain on address 1 to correctly communicate with
Simplicity
®
LINC. To change the address to 1, press the
Com/Setup button 3 times in succession.
Under unusual circumstances it could take up to two
minutes for newly updated data to be seen.
This product has been
tested at a qualified BACnet
testing laboratory and
found to comply with all the
necessary interoperability
requirements.
