Special applications and procedures
10.7.1
Triggering the Teach-in match code 1 and activating the code comparison via
the "Sensor 2" switching input
Code comparison functions
In Reading mode, the ICR845-2 compares up to two defined match codes with the codes it
recorded in the reading pulse. The result status of the code comparison is indicated by the
corresponding functional assignment via the "Result 1" and "Result 2" ("Result" LED) switch-
ing outputs and the beeper, depending on configuration.
The match codes can also be used as output filters for the host interface on Good read:
Without output filter the ICR845-2 outputs all recorded codes.
With output filter, the ICR845-2 only outputs those codes that have the same code ty-
pe, code length, and data content as the match code(s).
Definition of the match codes as base of the code comparison and activation of the code
comparison can be done in different ways.
Table 10-5
lists an general overview about the functions of ICR845-2 which are interrelated
to the code comparison for both match codes:
