NOTE:
The new OS must be sent using xmodem protocol using Tera Term. See
Terminal mode
commands general (p. 26).
To load a new operating system:
Enter terminal mode by typing
Open 0
(for a sensor with the default ID 0)
This will return the prompt: CS136>
Type the command:
LOADOS
The SkyVUE 8 will respond:
Load OS into DSP
DO NOT REMOVE POWER DURING OS UPDATE!!!
Waiting for xmodem
At this point, use your terminal emulator to send the appropriate file. Loading the OS could take
a few minutes.
When the process is complete the SkyVUE 8 will return the message:
Updating DSP OS, please wait....PASS
Updating TOP OS, please wait....PASS
Updating PSU OS, please wait....PASS
Wait 40 sec for OS to restart
Afterwards, the SkyVUE 8 will resume operation according to the previously set operating
parameters. It will no longer be in terminal mode.
5.1.10 Stratocumulus backscatter calibration
The
SCCAL
command allows a simple stratocumulus backscatter calibration of the scatter
coefficient measurements. This requires a human observer to confirm a stable Stratocumulus
cloud layer between 250 m (820 ft) to 2500 m (8202 ft) without holes, precipitation or reduced
visibility, and has been stable for at least 10 minutes prior to running this command.
Set the Measurement_Period to 10 (see Table 5-1 (p. 28)).
A detailed description of this technique is given in: Ewan J. O’Connor, Anthony J. Illingworth, and
Robin J. Hogan, 2004: A Technique for Autocalibration of Cloud Lidar.

and Ocean Technology , 21, pp 777 – 786.
