err=DaqWriteSerialNumber(DeviceIndex
USB-1208FS: Write a new serial number (an 8-character string) to the
device. The serial number consists of 8 bytes, typically ASCII numeric or
hexadecimal digits (i.e. ‘00000001’.) The new serial number will be
programmed but not used until hardware reset. As far as I know, the only
use of the serial number is to distinguish multiple USB-1208FS devices
attached to the same computer.
