Description
CMBn
&|
Sets the Baud Rate:
1200 if n=0
2400 if n=1
4800 if n=2
9600 if n=3
19200 if n=4
38400 if n=5
57600 if n=6
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.

Description
CRLRn
&|
Sets the resolution with which the percentage of dry
sensitive surface of the sensor is detected:
1% if n=0
0.1% if n=1
Default
: 1% (n=0)
RRLR
& n|
Reads the resolution with which the percentage of dry
sensitive surface of the sensor is detected.
CRTn
&|
Sets the precipitation detection threshold to n value,
where n is the percentage of dry sensitive surface of the
sensor below which the instrument indicates that a
precipitation is in progress.
If the 0.1% resolution is set, the value must be ex-
pressed in tenths (for example, write 950 to indicate
95.0%).
Default
: 95 (=95% with 1% default resolution)
RRT
& n|
Reads the setting of the precipitation detection thresh-
old.
