Reprogramming The Security Key
The security key on the PSA3 controller board can be reprogrammed
with a Software Program Exchange (SPX) module. The SPX is an
intelligent module that plugs into the debug port on the back of printers
equipped with the PSA3 “Hurricane” controller board. The SPX is used
only once; it automatically overwrites itself after successfully
reprogramming a security key. This allows the end user or a service
technician to enable features such as new emulations without having to
remove covers and install a new security key on the controller board.
The SPX is used at power-up only and is not left in the printer during
normal operation. Because it is a single-use disposable item the user is
not required to return it to the vendor or manufacturer.
How To Program The Security Key
1. Power off the printer.
2. On cabinet models, open the rear door. On pedestal models, refer
to Figure 25 to locate the debug port at the rear of the printer.
3. Insert the SPX into the debug port as shown.
