COUNT
 Get the number of samples per channel that have been acquired by the AISCAN operation.
Message
"?AISCAN:COUNT"
Response "AISCAN:COUNT=value"
value The number of samples per channel acquired.
Example "AISCAN:COUNT=64"
Note This message is processed by the DAQFlex Software library, and is not sent to the
device.
EXTPACER
 Set the configuration of the device's external pacer pin.
Message
"AISCAN:EXTPACER=value"
Response "AISCAN:EXTPACER"
value ENABLE (for most devices), DISABLE
Example "AISCAN:EXTPACER= ENABLE"
Note  Some devices support ENABLE/MASTER, ENABLE/SLAVE, or ENABLE/GSLAVE.
 For devices which do not support a master and slave configuration, the /MASTER and
/SLAVE designation is ignored.
 For devices which do not support disabling of the pacer or SYNC input (for example,
the terminal is always enabled as either input or output), the DISABLE designation is
invalid.
 Set to ENABLE if the device is paced using a continuous clock source, such as a
generator. In this mode, the first clock pulse after setting up the scan is ignored in
order to ensure adequate setup time for the first conversion.
 Set to ENABLE/GSLAVE if the device is paced from a DAQFlex supported device. In
this mode, the first clock pulse after setting up the scan is held off to ensure
adequate setup time for the first conversion. No pulses are ignored.
 When the external pacer is enabled, the AISCAN:RATE property should be set to
approximately what the external pacer rate will be, because internal transfer sizes
are calculated using the rate and channel count.
 When not specified, the default is DISABLE.
 Get the configuration of the device's external pacer pin.
Message
"?AISCAN:EXTPACER"
Response "AISCAN:EXTPACER=value"
ch The channel number.
value ENABLE (for most devices).
Note Some devices support ENABLE/MASTER, ENABLE/SLAVE, ENABLE/GSLAVE,
DISABLE/MASTER, or DISABLE/SLAVE.
