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.

RE: *Newbie* Trying to setup RS232 port..

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

RE: *Newbie* Trying to setup RS232 port..

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
