Specification in useful bit - stop bit - parity format. Therefore, the frame always comprises 8 useful bits
and 1 stop bit. Only the parity is differentiated.

Sampling rates for digital sensors
with up to 2 digital sensors with baudrate = 9600
and generally with baud rate > 9600 baud
at baud rate = 9600 baud and more than 2 digital

Baud rates above 9600 are supported only by JUMO tecLine sensors and JUMO sensors with JUMO
digiLine electronics. JUMO ecoLine sensors support only a baud rate of 9600.
b
For JUMO ecoLine O-DO sensors, the sample rate can be adjusted (1 to 999 s).
