Having problems with TTL on Vista
Hello everyone, I am a graduate student from Taiwan. My english is not very well (or poor, I think). But I'll try to express my questions clear :)
I've been working on MediaLab to let it synchronize with Biopac MP150 (with UIM100C), but have confronted great troubles.........
Computers bought these years seem not having parellel port at all, so I bought one PCI I/O card (with parallel port) and successfully installed it 7 hours ago. By the way, the OS of my computer is Vista 32-bit.
However, when I downloaded the patched IOTest from this forum and started to test it, in the Port Address field it always showed "LPT1: Error", "LPT2: Error", "LPT3: Error". I've tried to type the decimal values of the port (the hex value is DC00-DC07; D480-D487) and set the byte value and time to 255/50, but there were changes in Monitor field, the value remains 0.
At first, I thought this was the problem of the I/O card, so I went out and bought another one. However, both of them are made with Moschip's chip, so I think they are the same. And result is the same as well (sigh....)
Then, I thought this might be the problem of Vista, so I used the IOTest program on the other computer with XP. The result was a bit of different, this time, Port Address field showed "LPT1 Absent" rather than "LPT1: Error". This was rather convincing, because this computer surely has no parallel ports.
Can anyone gives me some suggestions and hints? Without letting MediaLab synchronize with Biopac, I can not graduate :( .....
Thanks for your watching, hope my extremely poor english didn't make the questions more difficult to understand.
Best regards
