Si certo tenendo presente che se apri e modifichi ti assumi tutte le responsabilità in caso di malfunzionamenti,
cmq questa è la procedura
Generally, the upgrading process is easy but it still need somebody have common sense on electronics engineering. The following are the instructions, please make yourself confident on doing below steps. Thanks.
1, Remove the screws from the enclosure and then take the enclousre off the main board.
2, Short connected two pins(GND and the one next to it, near J4) on J2 on the board(see image attached,double check this step before moving to the next!). Make sure doing this step without powering up! You can use tweezers or any metal things to short connect these two pins.
3, Use a USB cable to connect with a computer.
4, Power up the module with 12V(through Seatalk port).
5, You should see a disk drive named as 'STM32' on your computer.
6, Copy the new firmware(.bin file, down load by clicking the following link) to this disk drive.
https://www.quark-elec.com/doc/A027_V1.1...5_D348.zip
Make sure the full file has been coped to this driver before doing the next step! Nomally, it takes 5 to 8 seconds.
7, Turn off 12V power supply.
8, Remove USB cable.
9, Remove the jumper on J2. Makes sure you done this! Some customers reported they have issues but in fact they just forgot to remove this jumper!
10, Job done! Put the main board carefully back into the enclosure.
caricata l ultima versione lo strumento funziona perfettamente e traduce i dati seatalk correttamente.
