    BIOS Supported Display Types The littleMONSTER supports a vast variety of panels all configured by a dedicated cable for each panel. There is no jumper setting or software setup required. Since practically all LCDs have different connectors, pinout or LCD voltages, this is the easiest and safest way to configure different panels.

  • Page 33: Power Supply

    TFT Color 1024x600 Power Supply The grafic controller on the littleMONSTER board needs +5V only to supply attached displays. On board 3.3V-circuitry and low-voltage panels are powered by their own voltage regulators, placed on the cables itself. If the used backlight converter needs +12V, supply system with +12V also.
  • Page 34 This converter usually generates between 60 and 1000 Volts AC and has to be put as close as possible to the backlight to avoid capacitive loss on long cables. littleMONSTER uses a MOSFET to switch backlight on or off via software control. The configuration on the display adapter decides whether to switch +5V or +12V to the backlight converter.
  • Page 35 SW_BACK switched backlight converter supply voltage from MOS switch +12V only available if supplied via the PCI bus ground N.C. Do not make connections to this pin BACK_SRC backlight converter supply voltage input to MOS switch N.C. Do not make connections to this pin N.C.
  • Page 36 Onboard I/O, Printer-Port The Centronics printer interface on the littleMONSTER can be programmed via the system setup menu. The user can program the base I/O-address 378h, 278h, 3BCh or disable the interface. The parallel port is completely compatible with the parallel port implementation used in the IBM PS-II-Parallel Adapter.
  • Page 37 (*) If bit7 of the line control registers is 1 If the line control register bit7 is 0, data will be written to the TX- buffer. A read command from this port transfers data from RX-buffer. If the line control register bit7 is 1 the LSB of the divisor latch is enabled on I/O- address x0 and the MSB at address x1.

    ISA Bus Buffer In order to drive large backplanes, all ISA output signals on the littleMONSTER board are buffered via bus drivers. If external ISA-Cards are used, it’s strictly recommended to avoid address conflicts with onboard devices, otherwise the littleMONSTER board or the ISA card could be damaged.
