It does work when creating arb on the PC. TTSource sends it to the HDG directly. But you can save your arb in an ASCII file (.hfw), put it on a usb stick or microSD and open it on the HDG... and this doesn't work for me.  I could also create a new arb on the HDG, edit points but could not play them.. :-// I will try it again later on but editing an arb point by point on the HDG ... |O
At least you should be able to load a file created by TTSource so that you can work without the PC.

Alright, that sounds... not super bad I guess. Can't have it all for such cheap price. But damn you guys, I just had to order one of these so I'll see for my self!

Mine should be in the mail in the day or so ;)   I will of course void the "warranty" as soon as I can. If you want me to look for/at anything in particular let me know.

Just connect your USB to TTL interface to the board (the one you used for your Hantek MSO/DSO hack, and yes on the same pins), start your console (Kitty or whatever you like) and power up! Go to /etc, edit system.inf and replace HDG2002B with HDG2102C, save, reboot (do not switch off, type “reboot” or it will not work)… and that’s it.

noob question; does this mean the change is then persistant or the reason you have to type reboot is that a cold boot reloads the system.inf file and so you have to do this manually every time you turn on the system? If the latter how do you manage this on a day-to-day basis; wire in the USB link "permanently"?

also - from top photo - is the UART header the one near the USB jack??

... I had just ordered a HDG2002B, was regretting I had not ordered a faster model -  and then found this posting after the fact. So I've some USB 2 RS232/TTL devices on way from Aliexpress and will be keen to apply your advice...  :-+

You have to reboot manually just once after you have modified system.inf. Then the mode will be persistent. If you don't, you will lose your system.inf modification after switch OFF/ switch ON.
In fact I lost the mod once after the lan upgrade... I modified again system.inf and now it's persistent again.

Yes. Four pins were already soldered on it. Starting from the USB side and not counting the first one you don't need, you have RX, TX, GND and 3.3V
