NeuroWorks can also insert annotations during recording for each trigger.
Configuration of the trigger inputs is available in EDIT – SETTINGS – ACQUISITION – ADVANCED:
In Free Running mode, every change on the 8 inputs generates an event in the NeuroWorks study. This
mode is typically used when trigger pulses arrive at different timing on each of the 8 input ports. Resulting
in the following trigger values:
 Trigger on TRIG 1 input → generates a square wave and annotation with value 1
 Trigger on TRIG 2 input → generates a square wave and annotation with value 2
 Trigger on TRIG 3 input → generates a square wave and annotation with value 4
 Trigger on TRIG 4 input → generates a square wave and annotation with value 8
 Trigger on TRIG 5 input → generates a square wave and annotation with value 16
 Trigger on TRIG 6 input → generates a square wave and annotation with value 32
 Trigger on TRIG 7 input → generates a square wave and annotation with value 64
 Trigger on TRIG 8 input → generates a square wave and annotation with value 128
In Latch mode, the status of all 8 inputs is recorded as an 8-bit value, but only when a trigger pulse is
applied to the Latch input. An event is also inserted in the NeuroWorks study. For example:

wave and annotation with value 3 (= 1 + 2)

square wave and annotation with value 134 (= 2 + 4 + 128)
