I have a Raspberry Pi that I want to hook up to a serial (RS232) cable. I've found and read some information about this, so I know what pins on my RPi are Rx/Tx/3.3V/Gnd...
Now the cable I'm hooking it up to has a standard RS232 connector on one end, the other end is just four female header connectors. I do not know which if the 4 connectors is which Pin for the RS232.
Will I cause any trouble if I "guess" which pin on the RPi should be connected to which of the header connectors? I'm thinking it just won't work right until I get the combination right, but I'd hate to screw up the board because I guessed wrong.
The cable has been around for a while, there's no documentation or anything. It has HAURTIAN E164535 and I bunch of other stuff printed on it, but when I searched for that it just showed a standard RS232-RS232 cable, not what I have. Also I can't seem to find this "HAURTIAN" company to check for documentation there.
