Setup and Adjustments
Setting the Device Addresses
Use the local display or MAP Gateway to set up device addresses. Verasys field controllers are devices on MS/TP
Sensor buses. Before operating field controllers on a bus, you must
set a valid and unique device address for each
controller on the bus through the local display or MAP gateway. Device addresses 4 through 127 are the valid
addresses for these controllers.
Refer to the Verasys® BACnet® MS/TP Communications Bus Technical Bulletin (LIT-12012362) for more
information on field controller device addresses and how to set them on MS/TP buses.
