Your port information should be in "system Information" if your using XP.
Go to:- Start-
           Programs-
           Accessories-
           System Tools-
           System Information-
           Components-
           Ports-
           Parallel.
You should then find the port address

Thanks Jim, I found the info there thats looks much more like the info that i needed, 9c00 address, I changed it in Mach but i have no way to test the port tonight, i brought the computer home because i thought i was in for a long night. Unless you guys have some way to test it otherwise. Thanks to both you and Hood for your Help on this matter.

Best Jp

Hood,
I tried what you suggested and it didn't work. One of the problems I'm had was the number I put into the port setting was not what you showed. What I have under resources type (I/O range setting (FCF8-FCFF) I am using a Quatech SPPXP-100 Express card in the LPT3 port. As you can see all I have is letters basicly... any help would be appreciated... Thanks
John

John, I have sent you a personal message.

 Brett has probably got you sorted but if not then you want to put FCF8 as your port address.

 You could put a voltmeter on one of the pins to ground and set it up in ports and pins and toggle it High/Low and you should see the voltage change.

My Next mach Project is going to be a cinnn Mill 160 v with a 21 position rotary tool  changer. Im sure i will be back on soon.
