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

specic 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

congured to operate at the specied 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 congured to

“auto” detect the Baud rate of the network. In this conguration, 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 eld. The photos and table below

show the Baud rate dipswitch settings.
