The other main function of the FDU is to communicate with the locks to program them to
recognize the correct keycards for the door on which they are installed, to set the lock's
internal clock, or to download the audit information stored in the lock.
Most properties operate with more than one FDU to ensure there are sufficient units
available at all times for issuing keycards to guests, and to provide a backup in case one
of the FDUs requires servicing or is in use programming or auditing locks. All of the
FDUs on a property are equivalent, and can be used interchangeably by using one FDU to
synchronize all other FDUs on a regular basis by transferring data between units (refer to
Section 3.5.4 – Transferring Data to Another FDU). Up to 64 FDUs can be used on a
single property.
The portability, compact size and low weight of the FDU, plus the fact that it requires no
database or computer network, makes it an extremely versatile and reliable tool.
2.4 Communication Cable
The FDU can be connected to the lock for programming or auditing using the
communication cable, which has an infrared transceiver at the lock end. The transceiver
end is constructed differently for each lock model, so that the transceiver is correctly
positioned in front of the lock transceiver located behind the indicator light. The other
end connects to Serial Port A on the rear of the FDU.
