Configuring Device Communications

3.3.1 Confirm the Device and ProtoNode COM Settings Match

•
Any connected serial devices MUST have the same baud rate, data bits, stop bits, and
parity settings as the ProtoNode.
•
Figure 4 specifies the device serial port settings required to communicate with the ProtoNode.

3.3.2 Set Node-ID for Any Device Attached to the ProtoNode

•
Set Node-ID for any device attached to ProtoNode. The Node-ID needs to be uniquely assigned
between 1 and 255.
•
Document the Node-ID that is assigned. The Node-ID assigned is used for deriving the Device
Instance for BACnet/IP and BACnet MS/TP. (Section 7)
NOTE: The Metasys N2 and Modbus TCP/IP field protocol Node-ID is automatically set to be the
same value as the Node-ID of the device.
