4.5 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. 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.
