Older versions
V 040203 DL850 270.EXE
V 040303 DL850 270.exeSW-D009 4.03.03
Software with corrected diagnostic features and correction for the occasional white screen problem. See forum or data bullitins for more info.
V 040304 DL850 270.850SW-D009 4.03.04 DL850 270
Version with many improvements and some new features including remote trip reset.
V 040307 DL850 270.EXESW-D009 4.03.07 DL850N/D27 software for DL850 270 kHz
1 Bug fix, a missing ; in code meant that after production an error could occur that maid the gain curve wrong in bottom track mode. This could cause problems in some cases and can be seen by almost continuous flashing of LED800 on PV271 receiver card. Now fixed 2 Bug fix, During production the WT gain is changed, this was not updating in this version, now fixed

1 Made NMEA output work at 1 second (previously went faster) 2 On upgrade, the Trip is correct.(previously changed to negative number over a certain value) 3 Standby and reboot fix to make this go quicker. (It slowed down in 4.03.03) 4 Fix of white area in diagnostic screen in night screen (June) 5 Bug fix of introduced problem with bootup with NMEA on input 6 Position from GPS. N-E swapped

1 Correction of Speed limit settings, The settings are now saved through a system restart.
V 040401 DL850 270.EXESW-D009 4.04.01 DL850N/D27 (Build August) software for DL850 270 kHz version
1 Addition of diagnostic for lost STW; 2 Addition of method to remove a single beam with error; 3 Removal of Low and high speed Alarms; 4 div. screen updates; For diagnostic information see databullitin SDB_DL850_19 Beam failure causing STW Error
V 040402 DL850 270.EXESW-D009 4.04.02 for DL850 270
1. Temperature instability bug fix 2. Delay between WT samples is increased 2x times for three shallowest ranges. ("Screen scope","Menu","WT min" is actually 300ms on all depth ranges when display showing 150ms) 3. The number of the channel, which is excluded from calculations is indicated on the status screen 4. Digitizing error fix. Digitizing was enabled at startup. Now it is disabled.
V 040403 DL850 270.EXESW-D009 4.04.03 for DL850 270
version, bug fix in trip counter.
V 040405 DL850 270.EXESW-D009 4.04.05 for DL850 270
Temperature compensation mechanism has been changed. 1. Removed all old switches, which were never used. 2. Implemented New button at Screen calibration, Menu 4, two beeps. [Temp comp] On/Off 3. When [Temp comp] On, both speed of sound in the water and in polyurethane are recalculated based on the present temperature. 4. When [Temp comp] Off, both speed of sound in the water and polyurethane are fixed and can be changed from the softkeys. 5. Two separate calibration tables are implemented and will be used according to the setting of the Temp comp parameter. 6. After upgrading the old calibration table will be saved, but the [Temp comp] will be forced ON with empty calibration table. 7. Note. There is no automatic detection of the temperature sensor malfunction. If this is a case, the [Temp comp] must be switched OFF.
V 040406 DL850 270.zip SW-D009 4.04.06 release notes. - Implemented New button at Screen calibration, Menu 4, two beeps. [Temp comp] On/Off - After upgrading the old calibration table will be saved, but the [Temp comp] will be forced ON with empty calibration table.
V 040408 DL850 270.EXE SW-D009 4.04.08 release notes 14 MAR 2019
Temperature compensation mechanism has been changed.
1. Fixed error of second calibration table memorizing.
2. Minor bug fixes
