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.
