Campbell Scientific PWS100 Present Weather Sensor - Manual (Page 76)

Section 7. Operation
7.5.3 Viewing Data Output on the Command Line
A number of records (defined by the number n) of uncollected historic m data
(message data) can be output to the command line in ASCII text format in
exactly the same format as defined in the messages. To do this type:
HMDATA n ↵
If the parameter n is omitted then all uncollected data is output. Any output
message of either interval or polled are stored in a large final output buffer and
any uncollected data can be collected using this command. See Section 7.5.4
for the preferred method of collecting this data.
7.5.4 Collection of Data in Text File Format
A number of records (defined by the number n) of uncollected historic m data
(message data) can be collected using Xmodem 1 k protocol. To do this type
the following on the command line:
XHMDATA n ↵
If the parameter n is omitted then all uncollected data is collected. Any output
message of either interval or polled are stored in a large final output buffer and
any uncollected data can be collected using this command. This command
would normally be used for scheduled collection using a computer. The file
downloaded is a text file with messages in exactly the same format as defined
in the messages.
7.6 Weather Related Commands
7.6.1 Setting and Viewing Weather Parameters
Visibility alarm limit parameters, a snow water content parameter and a mixed
precipitation threshold parameter can be viewed using the SETPARAM
command. To view these parameters, type:
SETPARAM ↵
The PWS100 will then display three visibility alarm limit parameters, the snow
water content parameter and the mixed precipitation threshold parameter (four
total) on screen in the following format:
vislim1 vislim2 vislim3 snowwater mixthreshold
vislim1 = visibility limit alarm 1 limit (Default 5 km).
vislim2 = visibility limit alarm 2 limit (Default 1.5 km).
vislim3 = visibility limit alarm 3 limit (Default 0.5 km).
snowwater = snow water content (Default 0.5)
mixthreshold = mixed precipitation threshold (Default 0.5)
