RS232 Machine Link Cable

[User_123]

How do you check that the PC has the right port enabled? It only has three ports; 9 pin male (connecting to Denford), 9 pin female (connecting to screen) and parallel port (not used). I need to make sure the PC is right for the machine!

Thanks for your help but I think I'll just resale the machine and computer without the cable. My knowledge of electronics is too limited.

Stuart I don't think you have a 9 pin port to your monitor that is most likely VGA 15 pins.

I am not saying connect different to the drawing. I was trying to point out that besides the pins 2,3,7 there are other pins for handshaking etc.

The pc would normally have the port enable by default. But you could check in the bios to be sure.

Are you sure you are not getting mixed up with the pin numbering as you have a female on the pc


Did you look at this link by Peter http://www.denfordata.com/bb/viewtop...BI01812A#p8630 But I see you have posted there.
