I'm checking the correct pinout for this cable, the default is RS232, the truth is that the UV-5R is not compatible, the TXD pin is inverted, tomorrow I will build a cable for testing.
I confirm that it has swapped TXD and RXD... What a mess!

Can you share the CPS, so I can at least try to make some use of my unit?

Thanks

Re: Baofeng 1801 not enter in upload mode

You would need to unsolder the antenna connector to take the PCB out. Right now I won't do it. I have to think about reselling it or keeping. If I'm keeping it I could go for a full disassembly. The pad names on that PCB look like the are for Serial / RS232 style data They could be for debugging pu...

Re: Baofeng 1801 not enter in upload mode

This what I was able to get right now. I don't have a soldering iron with me so I couldn't detach the speaker in order to remove completely open it an detach the main PCB.

Re: Baofeng 1801 not enter in upload mode

Can someone confirm whether these new DM1801 radios are DMR ? Someone posted that they are FM only. Mine is definitely DMR. It share the same exact menu structure of the "old" DM 1801.

Re: Baofeng 1801 not enter in upload mode

Unfortunately today I got a DM-1801 that is not entering download mode. Fortunately I got it for a reasonable price so I'm keeping it. However there is something that is not like others... I can't talk to it using a USB to Serial Cable. I don't have right now the "slim one", the "direct one", but I ...
