The USB-2404-UI supports the following features:
Functions
UL: cbAIn32(), cbAInScan(), cbALoadQueue(), cbVIn32()
UL for .NET: AIn32(), AInScan(), ALoadQueue(), VIn32()
Python for Windows: a_in(), a_in_scan(), a_load_queue(), v_in_32()
Options
BACKGROUND, CONTINUOUS, BLOCKIO, HIGHRESRATE, SCALEDATA
HighChan
0 to 3
Count
When using input scanning, Count must be an integer multiple of the number of channels in the scan.
Rate
No channels configured in TC mode:
One or more channels configured in TC mode:
Range
| Voltage mode: | |
| BIP60VOLTS (±60 volts) | |
| BIP15VOLTS (±15 volts) | |
| BIP4VOLTS (±4 volts) | |
| BIP1VOLTS (±1 volts) | |
| BIPPT125VOLTS (±0.125 volts) | |
The Range argument is ignored when channels are configured for other input modes.

Only use cbVIn32()/VIn32()/v_in_32() when the channel type is set to Voltage. Using this method with other channel types will return a BADADCHAN error.
Specify this scan option with cbAInScan()/AInScan to acquire data at a high resolution rate. When specified, the rate at which samples are acquired is in "samples per 1000 seconds per channel".
Since these are high resolution devices, use cbWinBufAlloc32()/WinBufAlloc32Ex()/win_buf_alloc_32() to specify the buffer size when scanning data. To retrieve data from the buffer, call cbWinBufToArray32()/WinBufToArray32()win_buf_to_array_32().
