1.5 BACnet MS/TP BAUD RATE, BIASING & TERMINATION
1.5.1 Baud Rate
Every ONICON Btu meter is individually programmed at the factory with application
specific data provided by the customer during the process of ordering the meter, and this
normally includes the Baud rate setting. If the Baud rate was provided, the meter will be
configured to operate at the specified rate. The standard Baud rate settings are 9600,
19200, 38400 and 76800 Baud.
If the Baud rate setting was not provided to ONICON, the System-10 will be configured to
“auto” detect the Baud rate of the network. In this configuration, the meter should detect
and automatically adjust to the proper rate when it is connected to the network.
The Baud rate setting can be manually changed in the field. The photos and table below
show the Baud rate dipswitch settings.
