I have a random device: GT MEDIA V8 Finder Pro. I would like to communicate over its console port.
Here are some pictures of its mainboard. Here is the area around the console connector:
I have no idea if I should connect my RS232 adapter or my TTL USB adapter to it. I know that their previous model V8 Finder used RS232 levels, and also all their other boxes (Freesat V7, Freesat V7 MAX, Freesat V7Combo, V8 Series) use that, but am not sure about this one. I realy don't want to eather fry my TTL adapter or my Finder if I assume wrongly. Is there a good way to check?
I did check the TX pin with a multimeter, but it hardly moved, not much to see.
Now, if I knew what chipset this device uses it would be easier, but the only thing I know is that it's probably made by Ali
I know it's not an M3602, because my box can decode H265 and supports DVB-S2/S2X so it has to be a recent chipset (but because the heatsink is in the way, I can't check).
