Puo darsi che il tuo non abbia bisogno di aggiornamenti (dipende dal lotto di produzione: l'ho dovuto specificare nella richiesta).
Comunque, ti allego l'intera procedura da eseguire (compreso il link... che sembra un url temporaneo però):
Instructions:
1/ download the file to your clean USB stick here:
http://data.marmitek.com/downloads/Vincent/cnc83xx.bin
2/ update firmware of RX and TX; RX first, TX later.
3/ plug this USB stick to its 'service port'. Pull the pvc plug on the back to get to the USB port.
4/ re-plug its power
5/ wait until you see the logo come out.
6/ take out the USB stick, later re-plug its power.
7/ after finishing update RX, pls repeat 3~ 6 steps for TX.
8/ make sure you see the logo comes out before you take out the USB stick.
9/ wait until you see the video; if no video comes out after 3 min, re-plug the power of RX and TX again.
10/done
