*Newbie* Trying to setup RS232 port..

[niggle21]

Hi, i've got a Keyence KV-24T PLC and can't seem to get it to talk to the computer.. I've got the software installed fine but don't know if there's any settings i need to setup or what?


Can someone point me in the right direction please



Thanks,
Nigel.

Sorry, Keyence requires heavy duty registration for documentation accesss. Can't help. Life's too short for registration forms.

RS232 is on pins 2 and 3 and 5
Hardware?
Is it a db9?
DB9
Pin 2 Rx/TX
Pin 3 Rx/Tx
Pin 5 singal ground
Do you need flow control? probably not
Do you need hardware handshaking? probably not
check under device manager for these settings on your computer.

If you have a way to null modem your cable that is usually most of the problems with RS232, which is swap pins 2 and 3.

Also make sure that your computer is talking same baud rate, etc. The usual setting is "9600baud, 8N1"
8 = data width
N = no parity
1 = check bit
