THIS VERSION OF THE FIRMWARE WILL CAUSE A CHECKSUM ERROR ON INITIAL START-UP AFTER LOADING. THIS IS BECAUSE THE EEPROM MAPPING HAS CHANGED. MAKE SURE YOU RECORD YOUR CALIBRATION AND CONFIGURATION DATA PRIOR TO LOADING. There are pages at the back of the User Manual set aside for this.

This version of the firmware adds the feature that allows adjustment of the Low-Voltage Pre-Limit warning setting. In previous versions this limit was set at 100mV above the final limit value, but there are times when this is somewhat too sensitive. This version now makes this alarm threshold user adjustable between +100mV and 800mV above the Low Voltage trip value. Note that if you change the Low Voltage final limit trip, then the Pre-Limit trip point will automatically follow. For example, if your original Final Limit was 11.00V, and the Pre-limit was set at 11.20V, then if you subsequently changed the Final Limit to 10.50V, the Pre-Limit will then be 10.70V, +200mV as it was with the original value. You can of course alter it as you wish.

Because this version uses an additional word of EEPROM in which to store the adjustable Pre-Limit value, this will cause a Checksum Error on first power-up after loading. This will only occur the first time. To avoid having to re-calibrate the transceiver, make a note of your calibration and configuration settings before loading this new version. There are pages at the back of the User Manual for this data. It can also be dumped using the Serial Test mode.

Even though the kits have been discontinued, I will continue to provide both technical and software support for the foreseeable future.
