Operation
a) Display of the memory location numbers
The module has a two digit LED display for showing memory location numbers. The
last two digits of the memory number are represented by the two digits (00 ... 99).
The highest digit (0,1,2,3) for showing the full range of 000..399 are displayed by the
two dots on the top edge. The dot on the left side represents ‘+200’ and the dot on
the right side ‘+100’. Here are some examples for displayed numbers:
b) Clearing all 400 memory locations
Press down and keep down the key ‘program’ until the yellow LED marked ‘learn’ will
light up for the third time. Release the key while the LED is still lit. The ‘learn’ LED
will now ash quickly. Press the ‘program’ key again and keep it pressed for at least
1 second until the LED gets dark. The memory now is fully cleared.
If you enter clearing mode by accident and do not intend to erase the memory you
can exit while the LED is blinking by pressing the program key just shortly (less than
one second).
c) Learning and deleting ID tokens
The program key is pressed down and released right after the yellow ‘learn’ LED
turns on.
The number of the rst free memory location is shown on the display.
The ‘learn’ LED is dark to show the memory location is free. The memory location
number can be changed using the ‘up’ and ‘down’ keys. Used memory locations will
be indicated by lit yellow ‘learn’ LED.
After choosing any free or used memory location a new ID token can stored. If the
memory location was used before the ID number will be overwritten by the new
number. To do so, the new ID is read while the memory number is shown on the
display. The ‘learn’ led will ash quickly after a valid ID number was received.
If the new ID is already known, the display will show the memory location where this
ID is stored and the ‘learn’ LED will be lit to indicate the memory location is used.
This prevents that the same ID accidentaly gets stored in more than one memory
location.
To store the new ID on the selected memory location the program key is pressed for
at least one second.
To return to normal operation mode without saving any changes the program key is
pressed shortly (less than one second).
To delete a single memory location manually (for example if an ID token is reported
to be lost) the location is selected in learning mode and the programming key is
pressed for at least one second. The memory location is cleared and the module
returns to normal operation mode.
