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.
