I have a few problems with my GT31 / firmware v1.4 B0315c
My GT31 seems to miss some functionality in the 'Misc' menu for example: delete all and also the setting to activate 'looping' of 2s max/max run etc. in the my display.
To solve problem 1, my solution would be new firmware. But even with Tom Chalko's manual: no succes.
Every time I execute the GT31 Update I get the message: Frimware update failed: exit code:1. I just can't seem to get the firmware on the GT31. Any help is appreciated.
Btw: In my windows7 control panel, the device is listed under COM5 and I've selected COM5. So that should be ok
With the NavilinkII software I can make a connection through COM5 with my GT31. I can read data, but I cannot write date. For example I tried to write Tom's default setting, but I get an error: Error:ERROR_PORT
Hope someone can help me out
