Firstly I'll start with some questions regarding Instacal: Is Instical only used as a communication bridge between the PC and the interface box? Is there any extended info/manual available for it? I noticed the test area. And what gets me is that my term-lab fails both the analogue and digital tests?? Also I'm assuming Instical isn't an inhouse application? As I'd think it would be more user friendly to integrate it into Term-Lab? As well as removing the calibration button that causes so much problems. But getting back on track: Is there any use from the added functionality in Instical? And if so is there any documentation around it?
Not being funny but I'd apreciate a nudge in the right direction regarding these USB issues, I'd just like some further info on it. I'm unfortionate enough to have just replaced my motherboard with an SIS one (against my better judgement) and now seemingly have to dish out for the extra PCI card. I just find it odd that windows sees the usb unit and installs the HID drivers and that Instical picks up the interface box and under the configuration I click on "flash LED" and the LED on the box flashes, showing that there is two way communication. I'm asuming the low voltage variance of the meter is just too low to ensure communication back to the PC? So I'll be hunting for a PCI card tomorrow. But would still appreciate some info around this. Can I also assume that the symptoms mentioned for the above problem don't all need to be present? While I dont have any reading or the actual rate of 512 showing when started. I do have the constant green light and actual rate of 0. And I have yet to see the LED switch off while connected to the PC.
Another question before I go... The required voltage shown on the back of the interface box is between 14 and 25V DC. What kind of an influence would running it at 12V DC have on the system? Measurement wise? I'm hunting for a 14V transformer, would just like to know if I should worry about readings.
Thanks in advance

Instacal is used to tell the Term-LAB software what type of hardware is being used for data acquistion. There is no additional functionality offered.
The problem with the ALI and SIS chipsets has to do with the way "packets" of data are handled. I don't remember the specifics but high-speed data transfers are where the problems arise. I found the info on Microsoft's website about a year ago. Unfortunately, I don't remember where. There is no way to make Term-LAB work with these chipsets.
Term-LAB internally regulates to 12 volts DC. An input voltage of 14 VDC or more is required for regulation to take place. Term-LAB may be used with an input voltage of 12 VDC but be advised that this voltage should be very steady (such as a battery) for best results.

Thanks for the info. I'll move up my acquiring of a better power supply a notch.
