1.3.2 Cardfile and Plug-In Components
The GENISYS II cardfile is designed to house standard 6UX220 Eurocard plug-in printed circuit
boards. Most GENISYS II printed circuit boards are equipped with integral status indicator LEDs
on the board’s front panel.
In most applications, the cardfile will be equipped with a local control panel (LCP) that takes up
several cardfile slots. The LCP is interfaced to the cardfile circuitry and to the external inputs
through a dedicated non-vital I/O printed circuit board that occupies a cardfile slot directly
behind the LCP. Any unused slots in the cardfile are covered with blank shield panels. These
panels come in single slot and multi-slot widths. Each circuit board/panel is attached to the
cardfile frame with slotted-head machine screws. Two extraction levers are provided on each
board to make board removal easier. The GENISYS II cardfile can be wall- or shelf-mounted and
can be easily installed in a standard 19” equipment rack.
External wiring is connected to each circuit board through a 48-pin or 96-pin connector. Each
connector attaches directly to the board’s upper-edge connector at the rear of the card file.
Connector housings for I/O circuit boards incorporate a DIP switch that is used to set the
electrical address for the associated circuit board. The CPU connector housing has an internal
EEPROM that is used to store site-specific configuration data. Even if the CPU board is
replaced, the configuration data remains intact within the CPU connector’s EEPROM.
The GENISYS II cardfile plug-in components covered in this manual are listed in Table 1-2. See
Service Manual SM-6900A for a detailed description of each circuit board type.
