Appendix 68
Firmware version Description Released
0.723 1. NetCDF bugfix to avoid problems in ctrl process
2. support for new processor board (2015)
3. last Jenoptik release
Mar 2014
0.730 1. updated cloud algorithm during precipitation events
2. telegram over Ethernet support, now using port 11000
3. aerosol layer detection less sensitive in lower range to avoid
artefacts
4. range parameter in webinterface and command interface
implemented (RAR, RAS, RAE,RHD)
5. cloud detection is using new flexible range resolution to enable
precise post processing
6. Range2DIM in RangeHRDim renamed and max. set to 600 data
points
7. serial numbers of various components in EEPROM (opticconfig)
added
8. new serial number of mainboard (2015 edition)
Dec 2014
0.732 1. small adjustments to the cloud algorithm (lower false alarm rate
below 100m; signal smoothing changes)
2. first averaging starts at 3 km instead of 2.2 km,+ better
corresponds to met service requirements
3. DeviceName is preserved at reset settings to factory defaults.
4. Apply settings to factory defaults removed in web-interface (will
be redesigned and reintegrated in future)
May 2015
0.733 1. mainboard revision and processor board revision shown on web
interface
2. status code bit 12 (laser controller temperature) combined with
bit 13 (laser interlock) as new bit 13!
3. test firmware update for compatibility with processor board (error
on status code bit 12)
4. decrease valid Laser optical unit temperature from 62°C to 55°C
5. tolerance for APD temperature warning (status code bit 26)
increased, now 24°C < x < 28°C
Jul 2015
0.735 1. Settable altitude range enlarged to [-999m, 9999m], negative
values accepted now)
2. Settable range for RangeStart and RangeEnd changed
(RangeStart from [5,3000] to [5,1000]; RangeEnd from
[8000,15400] to [5500,15400])
3. show corrected laser life time (with LaserInstallTime) on web
interface and chmsettings.txt (same as in NetCDF file)
4. new telegrams predefined: #4 (correspond to #2) and #5
(correspond to #1) with the difference that the fan and heating
activities are shown at the end of the telegram and the altitude has
no positive sign to allow a larger altitude range
