5.5.1 Code
Verifier
If the DS4800 is used as a Code Verifier, the verifier code can be configured in software
through the Genius™ 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.
The Code Verifier parameter must be enabled, and the configuration parameters to allow
correct Code Type reading must be saved to the scanner in order to read the verifier code.
When the selected input is activated, the next read code will be stored as the verifier code in
the scanner's non-volatile (Flash) memory.
For more details see the Verifier Parameters in the "2K/4K Family Software Configuration
Parameter Guide” Help file".
5.6 OUTPUTS

Power Reference - Outputs
The meaning of the two outputs Output 1 and Output 2 can be defined by the user (No Read,
Right, Wrong, etc.). Refer to the Genius™ Help On Line.
By default, Output 1 is associated with the No Read event, which activates when the code
signaled by the external trigger is not decoded, and 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 configured
Activation/Deactivation events, Deactivation Timeout or a combination of the two.
