Product Code Number Description
MS-FIT100-0 The Field Inspection Tool or (FIT) is a portable handheld device with a user
interface that is used to test and troubleshoot the BACnet protocol MS/TP RS-485
communications bus that connects supervisory controllers and equipment
controllers to field point interfaces.
The FIT can be used to check out the wiring of the MS/TP RS-485 bus as well
as verify proper communications of supervisory controllers and equipment
controllers connected to the bus. The FIT can be used on both the FC Bus and SA
Bus.
TL-BRTRP-0 Portable BACnet/IP to MS/TP Router
