Problem with the error at DIO port configuration

[Maruthi]

I am working on the design of a model of a computer controlled Fuel Injection system using Gasoline Direct Igniton technology. I am using PCI-6025E as my data card and SCB-100 Connector block. My application is to get the digital input from the shaft encoder and the solenoids[acting as Inlet and exhaust valves]get actuated according to the VI. When I am trying to run the program theres an error 10001 occured at DIO port configuration. The statement is as" The error occured at the input string, the arrangement or ordering of the characters in the string is not consistent with the expected ordering". I checked the shaft encoder[S5S-50]pin out connections using an oscillograph and the voltages are as expected. Please let me
know the possible areas where I can figure out the error.

Maruthi;

You are probably using VIs that are not supported by that DAQ device. That DAQ device of yours only allow unstrobed digital updates, meaning that the digital lines will be updated by Software calls.

Since you probably need high speed/accuracy on your digital updates, you would be better served by using the PCI-6534 instead.

Hope this helps.
