Select the unipolar (0 to 5 V) input configuration by using the same 
setting as the 

 

±

 

5 V range setting shown in Figure C-5. You can use this 

setting because the ADC is 12-bit. Therefore, 12-bit resolution data is 
obtained in both the 0 to +5 V signal range and the 0 to -5 V signal 
range while keeping the input configuration for 

 

±

 

5 V input range. The 

jumper configuration for the 0 to 5 V and 

 

±

 

5 V input signal ranges is 

the same. The software handles the distinction between the two ranges.

 

You can install the PC-LPM-16 in any available 8-bit or 16-bit 
expansion slot in your computer. To optimize the board noise 
performance, install the board away from the video card and leave a slot 
vacant on each side of the PC-LPM-16, if possible. After you make any 
necessary changes with the jumper and switch settings, you are ready to 
install the PC-LPM-16.
