The overall accuracy listed above is expressed as percentages of the full
scale value of this AI module.
The response time listed above does not include the delay time of the
input filter.
The cable connected to each channel is one that is shielded either
separately from or together with the cables connected to the other
channels.
This AI module can only be used with the station's number-of-points setting set to 16.
If it is set to any other value (32 to 128), the module will not function.
The module supports only the value 16.
