Hardware features
 One digital port. All bits are individually configurable as input or output.
 Eight analog input channels, numbered 0 to 7. Possible gain ranges:
o ±10V
o ±5V
o ±2V
o ±1V
 External trigger input
 External pacer input / output. This feature allows multiple devices on a single USB to acquire
synchronized samples. One master device is used to drive the signal. Additional devices must be
configured as slave devices using the "AISCAN:EXTPACER=value" message. Value may be
"ENABLE[/MASTER]", "ENABLE[/SLAVE]" or "DISABLE".
 1,024 bytes of nonvolatile EEPROM memory; used for storing configuration information, calibration
data, and user data.
 RATE takes a float value. If the input scan rate requested is less than the slowest rate supported by
the device, the device is set to the slowest rate supported by the device. If the input scan rate
requested is greater than the fastest rate supported by the device, the device is set to the fastest
rate supported by the device.
 BURSTIO mode: the maximum sampling rate is an aggregate rate. The total acquisition rate is
200 kS/s divided by the number of channels. The maximum rate is 50 kS/s per channel for one,
two, or four channels, and 25 kS/s per channel for 8 channels.
When performing a finite BURSTIO scan, the maximum count is ≤32,768.
If a CONTROL IN message is sent or a CONTROL OUT message is received during a BURSTIO scan,
AINSCAN:STATUS:INTERRUPTED is returned. This property is not returned with BLOCKIO or
SINGLEIO scans.
