System Features
This chapter describes features of the processor board used by the
6180 Industrial Computer.
The onboard I/O controller (National Semiconductor 306B)
integrates the functions for the serial ports, parallel port, diskette
drives, RTC and keyboard. This component provides:
•
Multi-mode bi-directional parallel port
– Standard mode; IBM and Centronics compatible
– Enhanced Parallel Port (EPP) with BIOS/Driver support
– High-speed mode; Extended Capabilities Port (ECP)
compatible
•
Integrated real time clock with an accuracy of
13 minutes/year
•
Integrated 8042 compatible keyboard controller
•
Industry standard diskette driver controller with 16 byte data
FIFO (2.88 MB floppy support)
•
Support for IrDA-compliant (version 2.0) infrared interface. The
infrared interface supports data transfer rates of up to 115 Kbaud
with either half- or full-duplex operation. In full-duplex mode,
both the transmitter and receiver are enabled simultaneously for
faster throughput.
•
A 242-byte battery backed CMOS RAM
•
Two NS16C550-compatible UARTs with send/receive byte FIFO
The system BIOS provides ISA and PCI compatibility. The BIOS is
stored in Flash EEPROM on the processor board. The BIOS
provides the power-on self test (POST), the system Setup program,
the PCI and IDE configuration utility, the Windows 95 Plug and Play
and the BIOS recovery code.
The system BIOS supports shadowing, which allows the BIOS to be
executed from 64-bit onboard DRAM.
