transmitted.PVvalueistransmittedasrstmeasuredvalue,SVasseconedmeasuredvalue.
Information:
The max. value for the PV to be transmitted is 999.99 inches (cor-
responds to approx. 25.4 m).
If the temperature should be transmitted in the Levelmaster protocol, then TV must be set in the
sensor to temperature.
PV, SV and TV can be adjusted via the sensor DTM.

Set Baud Rate
Parameter Length Code/Data
Request: Set Baud Rate 8 (12) characters ASCII UuuBbbbb[b][pds]
Bbbbb[b] = 1200, 9600 (default)
pds = parity, data length, stop bit (optional)
parity: none = 81, even = 71 (default),
odd = 71
Response: Set Baud Rate 11 characters ASCII
Example: U01B9600E71
Change instrument on address 1 to baudrate 9600, parity even, 7 data bits, 1 stop bit
