JUMA TRX-2 Version 5.0a Build 7

This version improves the mode selection for the RS-232 port. In all previous versions the port was essentially active all the time in one mode or another, even if nothing was physically connected to the port. In certain, admittedly very rare, circumstances with a lead connected to the port and the transceiver connected to a computer then it was possible for stray characters to confuse the operating system. This version now has an additional 'DISABLED' mode selection so that even if stray characters are received they will be discarded and ignored.

This version can be safely loaded over a previous version 5, but as with all firmware updates it is a wise precaution to make a note of your existing calibration and configuration settings prior to installing this update.

After installing this version, remember to enter the User Configuration mode and reset the RS-232 port mode. As an additional mode value has been introduced, your previous setting will be incorrect.

If updating from an earlier version as the EEPROM mapping is different then on initial power up you will receive a 'Checksum Error!' message and the calibration and configuration defaults will be installed. This only occurs the very first time. Again, make a note of your setting prior to updating and reset them afterwards. If updating from an original version then as the measurement system is completely different you will have to re-calibrate your transceiver.
