Description
Channel assignments
AO0 delivers the threshold signal which can be set by the user within the
ASCO-DAQ2 software. It is connected to the analog threshold input of the
ASCO-P module. AO0 can be used to trigger the optocoupler output (pin 3
and pin 10 of connector J1) if the APK signal (before peak stretcher)
exceeds the defined threshold
AO1 is reserved for future usage and currently without function. The output
is available at pin 7 of connector J4.

USB driver LED
The LED next to the USB port at the rear panel indicates the status of the USB device. It will flash at a
frequency of 2Hz, if the DAQ2 module is properly detected by the PC (i.e. correctly enumerated, configured
and not suspended). A constantly on LED indicates that the USB device is not properly detected by the PC. In
this case see section 3.5 “Trouble Shooting”.
