Local Control Network - building controls in perfection
communication parameter of this transponder type (transponder family), has been learnt in
the LCN-ULT. After this, all transponders of the same type will be recognised and their ID
numbers transferred to the I-port. The further distribution of authorizations or mappings
from building functions for single ID numbers of different transponders, is done over the
LCN Bus (transponder-codes) or in access control (LCN-GVSU).
If a master card is accidentally held too long (more than 5 sec.) in front of the card reader, it
will flash red and change into the “erase” mode. Please remove the card straight away and
wait until the transponder reader stops flashing and the blue LED lights up permanently
again. Then go back into the “learn” mode again.
Preparing for operation / learning new transponder types with several LCN-ULT´s
If there are there more than one LCN-ULT in the building, it is possible to transfer the new
transponder types over the LCN Bus. In this case, all transponder readers will learn the new
transponder types at the same time. To do this, hold the master card (as decribed above) for
a short time in front of any one of the LCN-ULT´s until the LED flashes slowly. Now hold the
card in front of the LCN-ULT once more until the blue LED flashes up in a slow rhythm. If a
card from one of the new transponder types is now held in front of the LCN-ULT, the LCN-
ULT will transfer the transponder type over the I-port to the module. The module transfers
this information to all modules within the LCN Bus. The LCN modules transfer the
information over the I-port to the other LCN-ULT´s, so they can also evaluate the new
transponder types.
