1.5 RS485 BAUD RATE, BIASING AND TERMINATION
1.5.1 Baud Rate
Every ONICON System-10 is individually programmed at the factory with application
specific data provided by the customer during the process of ordering the Btu meter. This
normally includes the Baud rate setting. If the Baud rate was provided, the Btu meter will
be configured to operate at the specified rate. The available Baud rate settings are listed in
the table below.
If the Baud rate setting was not provided to ONICON, the Btu meter will be configured
to 9600.
The Baud rate setting can be manually changed in the field. The drawing and table
below show the Baud rate dipswitch settings.
