Introduction
1.3.8
Serial I/O
Two serial ports are supported on cPCI-6830.
The EIA232 drivers and
receivers reside on board. COM2 is a DB9 connector on the rear panel and
COM1 is available as a RJ45 connector on the front panel. Both ports will be
configured as DTE. Firmware will initialize the two serial ports as COM1 and
COM2 with ISA I/O base addresses of 3F8h and 2F8h respectively. This
default configuration also assigns COM1 to IRQ4 and COM2 to IRQ3. The
cPCI-6830 serial controller resides in the ITE IT8705F Super I/O
device.
1.3.9
IEEE-1284 Parallel Port/Printer Interface
The parallel I/O interface signals are routed to a DB25 connector on the rear
I/O module. This port supports the full IEEE-1284 specifications and
provides the basic printer interface.
Firmware will initialize the parallel port as LPT1 with ISA I/O base address of
378h. This default configuration also assigns the parallel port to IRQ7. The
printer interface mode (Normal, Extended, EPP, or ECP) is selectable
through the BIOS SETUP utility with the ITE IT8705F Super I/O device
managing the cPCI-6830’s parallel port.
1.3.10 Universal Serial Bus (USB)
The Universal Serial Bus (USB) provides a common interface to
slower-speed peripherals. Functions such as keyboard, serial ports,
printer port, and mouse ports can be consolidated into USB, simplifying the
cabling requirements of computers. The cPCI-6830 provides two USB ports
on the rear I/O module and is controlled by the VT8233 device.
1.3.11 IDE Controller and Floppy Interface Controller
The cPCI-6830 includes an IDE Controller (in the VT8233) and a Floppy Disk
Controller (in the IT8705). The IDE Controller provides support for internal or
external IDE drives. Signals are available at the IDE connectors CN5 and
CN6. IDE1 (CN6) can be connected to either a 40 or 44-pin pin header while
IDE2 is only available in a 40-pin connection. The FDD Controller provides
support for an external FDD drives. Signals are available at the FDD
connector CN8 and are routed to a 34-pin pin header.
1.3.12 Keyboard/Mouse Controller
The cPCI-6830 includes an on-board PC/AT keyboard and mouse
controller. The keyboard/mouse signals are available through the PS/2
circular DIN on the front panel. The cPCI-6830’s keyboard/mouse controller
resides in the ITE VT8233 device
