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 t 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.
