need help with parallel port

hi, i want to use paralel port to control some instrument device. i already read help tutorial for configure this port. but why error result always appear when use comand: daqhwinfo ? and why "winio"-drivers not appear when open device manager non plug and play device (i already use show hidden devices)? i use HP laptop with serial and parallel port installed, windows XP, matlab R2006a, and log in as a administrator.

many thanks agung

What error shows up when you use daqhwinfo ?

daqhwinfo is part of the Data Acquisition Toolkit. Do you have that toolkit installed and licensed?

[agung]

yup, i have.

sorry, for not captured that firs time trial. i will try again and capture the error.

can u explain about activated parallel port from device manager?

in help file that explain to chnge activated from demanded to boot? and why i cant see/found "winio" even i log in as administrator?

thanks for urs respons

To cross-check: do you happen to be using the 64 bit version of XP? The parallel ports are only supported on the 32 bit version of XP.

I suggest that you discuss this matter with Mathworks Support as an "installation issue" (there is free support for insallation issues.)

I do not have the windows experience to know about parallel port issues (other than to know that they can be difficult to solve.)

i already tried for some instruction, and still not working.

finally i do re-install windows OS with the same one on that machine and istall again mathlab r2006a. and magicaly thats work very well.

hehehehe.......

so i think previous case is a windows OS corupt or somethink.

but thanks for yours answer and respons
