Command protocol
9-17
?SNS
This query command
#LR?SNS*
requests data from the environmental sensor.
The reply, in the format
SNS=T;H;P
provides:
•
T: Temperature, in Celsius degrees (°C)
•
H: Relative Humidity in percentage (%)
•
P: Atmospgeric Pressure (hPa)
Example of reply:
SNS=23.9;38.8;1013.6
?SST
This query command
#LR?SST*
requests the level of the signal for the wireless channel.
The reply is in the format:
SST=l where l is the RSSI value, expressed in dBm, for the wireless network which the unit
is connected to.
When no network is detected, or the unit is disconnected, it returns SST=ERR
Example of reply:
SST=-67
?STA
This query command
#LR?STA*
requests the alarms status, regardless of the MSK setting.
The reply provides a string showing the following labels:
STA=AWUVPTCawvp
•
W: Warning level exceeded;
•
A= ALARM threshold exceeded;
•
w= end of Warning situation;
•
a= end of Alarm situation;
•
P= Probe failure ALARM;
•
p= end of Probe Alarm;
•
V= Low Battery ALARM;
•
v= end of Low Battery Alarm;
•
T= OverTemperature ALARM;
•
U= USB Connection Warning;
•
C= Relative Humidity ALARM
Note: each alarm is replaced by dash “-“ when not active.
Note: when an EHP-2B-xx probe is connected, "A" refers to the alarm in field E while "W"
refers to the alarm in field H.
Please, refer to ?MSK command for alarm masking.
Example of reply:
STA=-W-V-------
which means that the alarms for Field level Warning
and for Low Battery voltage are active. The probe has just detected a level exceeding the
warning threshold and the battery voltage is lower than 3.0 V, that is to say it is almost
exhausted.
