Introduction

The PCA-6277-B Series all-in-one industrial grade dual CPU card
uses Intel's highly acclaimed Pentium
VIA Apollo Pro133A chipset. The card works with standard ISA or
PCI/ISA-bus passive backplanes.
The CPU provides 256/512 KB on-CPU L2 cache, eliminating the
need for external SRAM chips. It has two PCI EIDE interfaces (for
up to four devices) and a floppy disk drive interface (for up to two
devices). Other features include two RS-232 serial ports (16C550
UARTs with 16-byte FIFO or compatible), one enhanced parallel port
(supports EPP/ECP) and four USB (Universal Serial Bus) ports. The
PCI enhanced IDE controller supports Ultra DMA 33/66/100 and PIO
Mode 4 operation. This provides data transfer rates of up to 33/66/
100 MB/sec. System BIOS supports boot-up from an IDE CD-ROM,
SCSI CD-ROM, LS-120, IDE HDD, SCSI HDD, ZIP-100, LAN, and
FDD.
A backup of CMOS data is stored in the Flash memory, which
protects data even after a battery failure. Also included is a 63-level
watchdog timer, which resets the CPU or generates an interrupt if a
program cannot be executed normally. This enables reliable operation
in unattended environments.
The PCA-6277-B Series offers several impressive industrial features
such as a VGA (AGP) controller, an ultra 160 SCSI controller, dual
10/100 Base-T networking controller, four DIMM slots for a total of 2
GB RAM memory, and an ISA High Drive. All these make it an ideal
choice for applications that require both high performance and full
functionality.
The remote management interface enables the PCA-6277-B to be
managed through Ethernet when it is connected to the SNMP-1000
Remote HTTP/SNMP System Manager.
