• Modbus:  Modbus enhancements and bug fixes
• Log format:  Support Sutron CSV log output format
• 4-20ma output:  Factory calibration added to 4-20ma output

Bug Fixes:

• SDRCommPC/PPC:  Use "SDR" as a default prefix when naming export files and the station name is blank
• Dual sensor:  Bug fix - Daily stage incorrect if second stage is enabled (Missing readings flag set)

Ditchmaster changes/bug fixes:

• DitchMaster:  Change 'target' to 'target flow' or 'target level' depending on user setting
• DitchMaster:  Added Volume Delivered to DitchMaster
• DitchMaster:  Added switch for DitchMaster diagnostics
• DitchMaster:  Allow user to set 'gate stuck limit'
• DitchMaster:  Display gate position with 2 right digits

Bug Fixes:

• 4-20mA input:  24V was not turned on at start of warmup
• 4-20mA output:  Output failed at hot temperatures
• Communication:  Warmup of 10 seconds and longer caused problems when talking to SDRComm
• SDRCommPPC:  App would crash if rating table was defined
• SDRCommPC/PPC:  Assignment of sdi-12 to device w/o analog resulted in analog selection

SDR 3.09 and SDRComm 3.0.4 (Feb 2008)

Major new features

• Dual Sensor:  setup SDR to measure a second stage using an analog* or SDI-12 sensor
• Rating Table: compute discharge using a rating table with up to 50 points
• Averaging:  stage can be computed by averaging multiple samples over a user-set period
• 4-20mA output:*    output stage or discharge using the 4-20mA circuit

*requires SDR w/ analog option SDR-0001-3 or -4

Other changes

• SDR now computes daily discharge
• Changed analog differential readings to report voltage rather than percent of full scale
• Added local time offset for use with GPS
• LCD Backlight is now on whenever the LCD is on
• SDI-12 communications improved
• Log can be searched by date via the front panel
