Introduction
The card index value of the PCIe-8154 can be set with a DIP
switch to a value between 0 and 15. This is useful for machine
makers if the whole control system is very huge.
2. Emergency Input
An emergency input pin can be wired to an emergency button
to stop sending pulse output once activated.
3. Software’s Security Protection
To secure applications, a 16-bit value can be set in the
EEPROM to prevent copying of custom programs.
