Command Reply Description
CMBn &| Sets the Baud Rate:

1200 if n=0
▪
19200 if n=4

2400 if n=1
▪
38400 if n=5

4800 if n=2
▪
57600 if n=6

9600 if n=3
▪
115200 if n=7
Default
: 19200 (n=4)
RMB & n| Reads Baud Rate setting
CMPn &| Sets parity and stop bits:

8N1 if n=0 [No parity, 1 stop bit]

8N2 if n=1 [No parity, 2 stop bits]

8E1 if n=2 [Even parity, 1 stop bit]

8E2 if n=3 [Even parity, 2 stop bits]

8O1 if n=4 [Odd parity, 1 stop bit]

8O2 if n=5 [Odd parity, 2 stop bits]
The number of data bits is fixed to 8.
Default : 8E1 (n=2)
RMP & n| Reads the setting of parity and stop bits.
CMWn &| Sets waiting time after transmission with MODBUS-RTU
protocol:

Immediate reception if n=0 (violates protocol)

Waiting 3.5 characters if n=1 (respects protocol)
Default
: Immediate reception (n=0)
RMW & n| Reads the setting of waiting time after transmission with
MODBUS-RTU protocol.
Measurements reading:
Command Reply Description
S0 &| Disables the sending of the measurements enabled with S1.
S1 &| Enables the sending of the measurements at regular inter-
vals. To set the sending interval, use the command MT.
S2 &
Measurements
Prints the measurements in the following sequence:

Pressure

Power supply voltage

Internal temperature

Measurement error:
0 = no error
1 = pressure error
2 = internal temperature error
3 = pressure and internal temperature error
The measurements are expressed in the set units of
measurement.
MTn &| Sets the measurement interval to n seconds (1…30 s).
Default : 1
NT & n| Reads the measurements sending interval.
