Electronic Key Interface (P33)
The printer is prepared to use up to three different electronic keys.
In addition to the electronic key fitted in P34 on the CPU board (see
chapter 15.3), one or two keys can be inserted through a slot in the
printer's rear plate and thus be connected to P33 on the CPU board.
The electronic keys are Dallas touch memory circuits with built-in
battery backup that can be programmed to add or lock out function-
ality in the printer or the installed software. The expected life of the
backup battery is at least 10 years.
There are a number of different types of keys with different
properties. Some have a non-volatile memory, which can be read
from or written to, some have a run-time clock with expiration
capabilities, while others have special password-protected memory
areas.
A key may contain up to 16 different key items. There are two types
of functions:
• Lock, which locks or unlocks specified features in the printer or
in the software. For example, a key may be required to unlock
a custom-made application program (copy-protection). If com-
bined with a run-time clock, it could e.g. allow use of a demo
program for a limited period of time.
• Storage, which is used to store short files of data.
Electronic keys for various purposes can be ordered from Intermec.
