1.1 INTRODUCTION
The AR-B1462 is a disk size industrial grade CPU card that has been designed to withstand continuous operation
in harsh environments. The total on-board memory for the AR-B1462 can be configured from 1MB to 128MB by
using all 72-pin type DRAM SIMM devices.
The 8 layers PCB CPU card is equipped with a IDE HDD interface, a floppy disk drive adapter, 1 parallel port, 4
serial ports and a watchdog timer. Its dimensions are as compact as 146mmX203mm. It highly condensed
features make it an ideal cost/performance solution for high-end commercial and industrial applications where CPU
speeding and mean time between failure is critical.
The AR-B1462 provides 2 bus interfaces, ISA bus and PC/104 compatible expansion bus. Based on the PC/104
expansion bus, you could easy install thousands of PC/104 module from hundreds venders around the world. You
could also directly connect the power supply to the AR-B1462 on-board power connector in standalone
applications.
A watchdog timer has a software programmable time-out interval, is also provided on this CPU card. It ensures
that the system does not hang-up if a program can not execute normally.
A super I/O chip (SMC37C669) is embedded in the AR-B1462 card. It combines functions of a floppy disk drive
adapter, a hard disk drive (IDE) adapter, four serial (with 16C550 UART) adapters and 1 parallel adapter. The I/O
port configurations can be done by set the BIOS setup program.
As an UART, the chip supports serial to parallel conversion on data characters received from a peripheral device
or a MODEM, and parallel to serial conversion on data character received from the CPU. The UART includes a
programmable baud rate generator, complete MODEM control capability and a processor interrupt system. As a
parallel port, the SMC37C669 provides the user with a fully bi-directional parallel centronics-type printer interface.
The special device is the AR-B1462 provides one audio connector, the sound system is built-in 16bit PnP sound
blaster with DOS and Windows drivers. In the same time the AR-B1462 provides network connectors that are 10M
bps NE2000 compatible. We designed the connectors for easily setup.
The super VGA controller supports CRT color monitor, STN, Dual-Scan, TFT, monochrome and colored panels. It
can be connected to create a compact video solution for the industrial environment. And provides the touch screen
header on the serial port 4 for multiple function.
Note: Just the AR-B1462A supported the audio function and supported 2MB on-board VRAM. The AR-B1462 only
supported 1MB on-board VRAM.
