ADLINK DAQe-2214 - Manual (Page 77)

Operation Theory 65
The trigger signal is generated when the analog trigger condition
is satisfied. There are five analog trigger conditions in the DAQ-/
DAQe-2213/2214 card. The DAQ-/DAQe-2213/2214 card uses
two threshold voltages, Low_Threshold and High_Threshold to
build these different trigger conditions. You can conveniently con-
figure the trigger conditions using a software application.
Trigger level digital setting Trigger voltage
0xFF 9.92V
0xFE 9.84V
0x81 0.08V
0x80 0
0x7F -0.08V
0x01 -9.92V
