host configuration
The Remote Terminal Unit needs to be configured to communicate and correctly interpret
data when reading input registers from the Rosemount 5300 Level Transmitter.
Baud rate
The specified Baud Rates below are recommendations. If other Baud Rates are used, make
sure the Rosemount 5300 Level Transmitter and the RTU are configured for the same
communication speed.
