Re: Trouble shooting digtal I/O



Right questions.
24V is not a problem: use a voltage divider to run to TTL levels. If you HAVE a logic analyzer, use that!
If this is low-budget, use a parallel port or two.

Four inputs and four outputs, from plc/pc. (that would be 8 inputs for whichever analyser i use) Since one device is a PLC it will take at least 1~2 mili sec for a scan. So i probably need 1 mili sec resolution. I do not need real time infor. just need relative time between switching.
Any inofo on how to use parrlel port for this aplication? or any i/o card and software that i can use?

Have you looked at the Ant8 http://www.rockylogic.com/ ? The memory depth is about 3000 samples; might be sufficient. It's not very expensive and is small enough to live in the laptop case.

Try something from www.datataker.com You hire them from companies like Tech Rentals if you only need it for a bit of troubleshooting.
AFAIK, the entire range can give you an output in the format you require.
