| Name | Direction | Range | Description |
| chan | input | 0-(N-1) (N is the maximum channel number and depends on the hardware. ) | The target channel. From a minimum of zero for the first AI channel to its maximum AI channel number minus one. For example, the range is from 0 to (N-1) on a device with N AI channels. |
| gain | input | Depends on the hardware. | GainCode. Refer to the hardware manual. |
| TrigMode | input | 0: internal 1: external |
The triggering mode. |
| voltage | output | Depends on the input range. | The return voltage value. |
