4.3.20 INTERACT HARDWARE KEY
The INTERACT hardware key can be used in all PROVIT 4000 Industrial PCs. The controller revision must be
taken into consideration:
Controller INTERACT Hardware Key
Rev. < 10.xx For controllers with a rev. < 10.xx, the INTERACT hardware key cannot operate on LPT1 alone. The
operation of an INTERACT hardware key internally in the device in conjunction with the LPT1
parallel interface is not supported. That means, the INTERACT hardware key can only be
operated internally.
Furthermore, software package such as e.g. Lap Link which normally use the parallel interface as
the communication port cannot be operated on LPT1!
Rev.
≥
10.xx For controllers with a rev.
≥
10.xx, the INTERACT hardware key is operated by the LPT2 interface
which is not available for the user. That means, the operation takes place via the I/O addresses 278 -
27F. An IRQ is not triggered. The INTERACT hardware key can be operated externally (LPT1) and
also internally (in the key slot). Both can be used together for maintenance work.
The limitations stated above concerning the use of software packages are not valid for these
controllers!
