Hardware features
 8 analog input channels, numbered 0-7.
 Analog input mode is configurable for single-ended (8 channels) or differential (4 channels).
Gain ranges:
o ±20V (differential mode)
o ±10V (differential or single–ended mode)
o ±5V (differential mode)
o ±4V (differential mode)
o ±2.5V (differential mode)
o ±2V (differential mode)
o ±1.25V (differential mode)
o ±1V (differential mode)
 2 analog output channels, numbered 0 to 1.
Analog output range is 0 to 4.096 V, 1 mV per LSB
 2 digital ports. Each port is individually configurable as input or output.
 External trigger input
 External pacer input/output
This feature allows multiple devices 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
"ENABLE/GSLAVE."
o When set to ENABLE/SLAVE, the first clock pulse after setting up the scan is ignored to ensure
adequate setup time for the first conversion. Use this mode when the device is paced from a
continuous clock source.
