How can I set the programable gain on my AT-MIO-16L-9 so I can calibrate?

[SEMi1o1]

 I have been trying the follow the instructions in the AT-MIO-16 manual to do a calibration. The instructions require me to set the gain to different levels before tuning the trim pots. As of now my only means of software control of the DAQ is with the NI-DAQ configuration utility version 6.10. The card is runing in an old 98se system. Any hints on how I can set my programable gains would be greatly appreciated.

Hello,

I am assuming that the “NI-DAQ configuration utility version 6.10” you referred to is in fact the NI-DAQ driver, which is now more commonly referred to as the Traditional NI-DAQ (Legacy) driver.  The last version of this driver that works with non-E series AT devices (includes the AT-MIO-16L-9) is the 6.1 version of Traditional DAQ.  This driver is posted on the web with related documentation. 

I also looked into the specific section titled calibration procedures in the AT-MIO-16 manual.  This section states “To calibrate this offset, you must ground the analog input, read it at two different gain settings, and adjust a trimpot until the readings match at the two different gain settings.” under the Analog Input Calibration sub section.  You can change the gain by using programming functions in one of the supported languages of this driver version. These languages are listed in the NI-DAQ User Manual for PC Compatibles linked below.  LabVIEW, CVI, Microsoft Visual C++ 2.x, 4.x, or 5.0, Visual Basic 4.0 (32-bit) or 5.0, and Borland C++ 5.x are the listed languages.  There are command such as AI_Setup and AI_VScale that can be used to set the gain in one of the programming languages listed above.  Support documentation that downloads with the driver will have proper documentation of this function calls.
