8 PCM-3521 User's Manual
• Be sure that the CPU card is operating correctly.
• See if no other devices, such as a Flash/RAM/ROM
disk, CPU card, or DA&C card occupy the same I/O
address as the PCM-3521. If this is the case, consult
the device's manual to set it to an alternative address.
The PCM-3521 uses I/O addresses from 3BCH, 3BDH
and 3BEH which are reserved by the system for its
parallel ports.
If the problem persists, please refer to your flat-panel
display manual
