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 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.
