Portable Programmer
The Portable Programmer, commonly called the PP, is used to carry information
between the lock and the front desk equipment. It can also be used to open a
guestroom and to test the operation of a lock.
When the locks are first installed, the PP is used to initialize each lock to a particular
room number, load its table of room codes, and set the internal clock.
Note: Since the PP can be used to unlock a door, it should be secured when not in
use.
If you are unable to secure the PP, remove and reinstall one battery after use. This
will clear the memory and require that the PP be connected to the console before it
can be used again. Connection to the console requires a management level password;
therefore, proper security is maintained.
Batteries – Portable Programmer
The PP uses 4 AA batteries which are expected to provide about 50 hours of use. If
the display is not visible, the batteries must be replaced.
Connecting the PP to the Lock
The PP is connected to the lock with the plug on the attached cable. On the bottom of
the lock, to the right, you will see a hole (called a jack). Insert the end of the cable
(the plug) into the jack. Before you connect the PP to the lock, however, you may
first need to connect it to the console. This generally depends upon the operation you
wish to perform. In fact, the PP may inform you if it needs to be connected to the
console first. The reasons for this will become clear as you read further in this
section.
