READ BEFORE OPERATING
All individuals who have or will have the responsibility of using, maintaining, or
servicing this product must carefully read this manual. The product will perform as
designed only if it is used, maintained, and serviced in accordance with the
manufacturer’s instructions.
The B5C is a state-of-the-art transmitter that can operate as an independent, stand-alone
system or as part of an integrated system. Setup procedures are simplified with user
friendly push buttons and LCD menus.
The B5C is the Q5C gas transmitter with BACnet® MS/TP master protocol. Therefore,
the B5C does not support the 4-20mA and VDC analog output.
BACnet MS/TP protocol is a peer-to-peer, multiple master protocol based on token
passing. Only master nodes are allowed to send and receive tokens on the MSTP
network. Passive slave nodes on the other hand may only transmit data frames on the
network in response to a request from a master node. Passing the token represents
overhead in the sense that the messages used for managing the token do not carry data
that is useful to automation or monitoring.
The B5C can be set to be a Master Node or a Slave Node in the field. Factory default is
master node.
