PCI-DAS6000 Series

That driver is written by The Mathworks. After looking at their list of supported models, the PCIM-DAS1602/16 model seems like the best alternative.

Hello - For MCC PCI boards, if the same model board is swapped into the same PCI slot, the PC should not know the difference. As you have described in your case, your PC does detect a difference. Thus the conclusion is that one PCI board is bad. Field repair is not possible. If you are outside of the USA, you must contact the MCC distributor in your country, for RMA assistance. A list of our Distributors may be found at: http://www.mccdaq.com/contact2.aspx.

Assuming you have ruled out mechanical fit/mating between the board and the PCI bus, then the other two possible causes are: Having the incorrect driver, or that the board requires repair. In the case of the driver, install InstaCal before plugging in the board. Version 6.10 or later is required for Win7. If the board shows up as an unknown device in the device manager of Windows, delete the device from the device manager, and then reboot the PC.

The calibration constants are stored on the board itself, and are not known to be lost when powered down. If you are using any of our Windows software, you should not need to re-calibrate. Perhaps you are not talking about measurement accuracy (calibration), but instead are talking about needed to run the device discovery/configuration program that is named InstaCal? That may be a “write rights” issue, for the folder location where InstaCal stores the CB.CFG text file that it creates. There is an FAQ on our knowledgebase that may be helpful: http://kb.mccdaq.com/KnowledgebaseArticle50250.aspx

There is no added protection for the digital output on the PCI-DAS6025. The 82C55 interfaces directly to the outside world. An accidental connection of a digital output bit to a 5 volt source could cause irreparable damage to the 82C55 chip.

Hello Camilo - Our current MCCDAQ CD download, and the InstaCal download, both have the Windows 7, 32-bit drivers. You can download them from the following link: http://www.mccdaq.com/software.aspx

Hello The factory calibration of a PCI-DAS6000 board involves three steps: 1.) Measure on-board references, and store their values in the board’s EEPROM 2.) Run the InstaCal self-calibration, which takes the on-board references and routes them into channel 0, resulting in gain & offset correction factors being stored for each range into the board’s EEPROM. This is a “hands-free” step, requiring no external equipment or signals. 3.) Accuracy is verified by connecting known signals. Later, in the field, if InstaCal’s self-calibration is run, the gain & offset correction factors will be adjusted slightly. The self-calibration effectively adjusts slightly for the environment temperature, and is not needed to meet spec for the period of time covered by the cal cert. In your case, it sounds like the board is number of years old, and its original cal cert has expired. You could have the board returned to our factory for re-calibration for a fee. You could also perform step B (after full warm-up) and then check the accuracy yourself (step C) to determine if the accuracy on the range(s) you use still meet your accuracy needs.
