Network Integration 

The controller in this unit can easily be integrated into a BACnet MS/TP 
Building Management System. The controller will automatically detect the 
baud rate of the network it is connected to after a power cycle, and will 
automatically begin communications.  

The MAC Address is set via the dip switches on the front of the controller. 
When shipped, each unit will have a factory default MAC address with 
multiple units for the same project having incremented MAC addresses. 
The dip switches are numbered 1 through 8, with 1 being the LSB. The 
numbering is standard binary format (switches 1 and 3 ON equals an 
address of 5). 

The Network Instance Number (device instance) is automatically 
configured based on the MAC Address setting. The network instance 
number will always be 3640+(MAC Address). For example, if the MAC 
address is set to 25 the network instance number would be 364025. In the 
event of a duplicate instance number on the network, simply change the 
MAC address to change the instance number. 

The following page has a complete listing of the BACnet points with their 
descriptions.
