CS120A and CS125 Visibility and Present Weather Sensors
36
5 User Alarm 2 Enabled 0-1 User alarm two activation state
0 = Alarm two disabled
1 = Alarm two enabled 0
6 User Alarm 2 Active 0-1 0 = Check if distance is less than ‘User alarm 2
Distance’
1 = Check if distance is
greater than ‘User alarm
2 Distance’
0
7 User Alarm 2 Distance 0-
60000 Distance value that alarm one will trigger against.
This value will correspond to metres or feet
depending upon which is selected in ‘Visibility
Unit’ 10000
8 Baud rate 0-6 Baud rate for the main RS-232/RS-485 interface
0 = 115200 bps
1 = 57600 bps
2 = 38400 bps
3 = 19200 bps
4 = 9600 bps
5 = 2400 bps
6 = 1200 bps 2
9 Serial number - Internal serial number for the sensor.

10 Visibility Unit M or F Unit the visibility value will be presented as
M = metres
F = feet M
11 Message Interval 1-3600 Interval in seconds between outputs in continuous
mode. This value has no effect if polled mode has
been selected in ‘Measurement mode’ 60
12 Measurement mode 0-1 Selects polled or continuous modes.
In continuous mode the sensor will output a string
in the format as set by ‘Message Format’ at
regular intervals as defined by ‘Continuous
Interval’.
0 = Continuous mode
1 = Polled mode 0
13 Message Format 0-12 Output message
0, 1 and 2 = Basic, partial or full visibility
messages
3, 4 and 5 = Basic, partial or full SYNOP
messages
6, 7 and 8 = Basic, partial or full METAR
messages
9, 10 and 11 = Generic basic, partial or full
SYNOP messages
12 = Custom message 5
14 Serial port protocol 0-1 Selects the physical serial interface
0 = RS-232 mode
1 = RS-485 mode 0
15 Averaging period 1 or 10 The period of time that the visibility measurement
is averaged over. Either one minute or ten. 1
16 Sample timing 1-60 Used to define the time interval between sampling
the volume. It is recommended that this value is
left at one except when very low power demands
are needed. For example:
1 = Sample every second
2 = Sample one second in every two
3 = Sample one second in every three etc. 1
