Application #1 — Commissioning BACnet MS/TP using a Laptop Computer
Some BAS commissioning software was developed
for a BACnet/IP environment but could be used to
commission BACnet MS/TP devices if the proper
connection is made. The BAS Portable Router is a
perfect fit for this application. The BACnet/IP port on
the portable router connects to the laptop’s Ethernet
port using CAT5 cable while the MS/TP port connects
to the target BACnet MS/TP network. Power for the
portable router is derived from one of the laptop’s USB
ports using a USB cable. However, no communication
occurs over the USB port. Using the portable router’s
web page, the baud rate of the MS/TP port is set to
correspond to the baud rate of the MS/TP network.
There is no auto-bauding option with the portable router.
The target MS/TP must be assigned a unique BACnet
network address from that of the BACnet/IP network
created with the laptop connection. There is nothing to
preclude the use of multiple BASrouters on the same
MS/TP network as long as unique BACnet network
assignments are made to each created network.
