1.8.2 CONTROLLER
The controller employs RA2K architecture, which allows the board to control all
applications, including copier, printer, scanner, and fax applications. To add the
optional printer, scanner, or fax applications, ROM DIMMs must be installed on the
controller. The fax option, however, requires FCU and NCU installation also.
The following systems and application software can be downloaded from the
controller’s IC Card slot.
