7.2.1 Activation modes for status LED
Two operation types result by the setting of the parameter dwLedCon-
trolMode for the signaling of the Kemro UserID modules through the
status LED:
z Operation type 0 (status on delivery)
The device driver controls the status LED according to the schema
shown below. The read/write functions on the status LED from the ap-
plication remain without effect.
LED signals Designation / description
LED green (continuous) Default behavior if valid module detected
LED green (blinking, max. 3
sec.)
Readable transponder detected
The status LED blinks green as long as the trans-
ponder is within reading range (max. 3 sec.)
LED red (blinking, max. 3 sec.) Transponder could not be read; unsupported trans-
ponder type
The status LED blinks red as long as the transponder
is within reading range (max. 3 sec.)
Information
The signaling via the status LED merely provides information about
whether a transponder was able to be read correctly. Whether the stored
used on the transponder can actually be logged in on the system is not sig-
naled in this operating mode.
z Operating mode 1
status LED is controlled by the application. In this was, the LED can be
arbitrarily set by the application via the corresponding read/write func-
tions. An individual formation of the acknowledgement can thus be real-
ized through the status LED.
Information
The data basis for the user data is stored in the control or visualization sys-
tem and is retrievable by the associated application. Thus, the validity of
user data can be checked in the application and signaled via driver inter-
face through the status LED of the Kemro UserID module.
