7.4.1 Code Verifier
If the barcode scanner is used as a Code Verifier, the verifier code can be configured in software through the GeniusPlus
configuration program. However it is also possible to use one of the inputs to trigger when the scanner should store a code
read as the verifier code.
To read the verifier code:
1. Enable the Code Verifier parameter, and
2. Save the configuration parameters to allow correct Code Type reading to the scanner.
When the selected input is activated, the next read code is stored as the verifier code in the scanner's non-volatile (Flash)
memory. For more details see the Verifier Parameters in the TCNM-AD/EX/SP Family Software Configuration Parameter
Guide help file.

Power Reference Outputs
The meaning of Output 1 and Output 2 can be defined by the user (No Read, Right, Wrong, etc.). By default, Output 1 is
associated with the No Read event, which activates when the code signaled by the external trigger is not decoded. Output
2 is associated with the Complete Read event, which activates when all the selected codes are correctly decoded.
The output signals are fully programmable being determined by the configuration of Activation/Deactivation events,
Deactivation Timeout or a combination of the two.
