Hey, so I connected the serial with the pcb plugged the regular way:
I can't get putty to open a serial connection for some reason (I tried on putty on w10 with the COM6 port, I check the speed and options).
I tried on a linux puppy, did a diff inside the /dev, the name are either:
serial
ttyUSB0
I can't get it to open the terminal for some reason either.
For the record I connected: rx->tx, tx->rx , gnd->gnd
But I can get things by doing a 'sudo cat /dev/ttyUSB0', so it is communicating.
The w10 was a laptop, and the linux puppy was on another one.
I am going to try to use the 2nd usb to rs232 I got, I also need to try with 9600 as baud rate (I was using 38400b/s).
EDIT: I am using a desktop aside to power the hdd (my nas stuck in the bios). I was worried about ground looping but it seems fine so far.
EDIT: btw the R led is blinking (on the USB to RS232 stick) when it is plugged and then goes pretty much 'quiet' blinking from time to time.
