2 PCA-6155 User's Manual
Introduction
The PCA-6155 packs all the functions of an industrial computer,
including IDE, FDD controller, RS-232 ports and a parallel port onto a
half-size card. This PICMG-compliant, all-in-one board supports Intel
Pentium and Cyrix 6x86 processors and can be used with PCIMG-
compliant PCI/ISA passive backplanes.
The PCA-6155's two PCI-bus enhanced IDE ports support PIO mode
4 and DMA bus master IDE transfer, enabling data transfer rates in
excess of 16 MB/second. Up to four IDE devices can be connected,
including large hard disks (up to 8 GB), CD-ROM drives, tape backup
drives, or other enhanced IDE devices.
On-board features also include two RS-232 ports with 16C550 UARTs
(one of which can also function as an infrared port) and one bidirec-
tional SPP/EPP/ECP parallel port. It provides COAST (Cache On A
STick) pipeline burst synchronous cache RAM. The PCA-6155 can
pack up to 128 MB of memory, using normal DRAM or EDO RAM.
If program execution is halted by a program bug or EMI, the board's
63-level watchdog timer can automatically reset the CPU or generate
an interrupt. This ensures reliability in unmanned or standalone
systems. The watchdog timer interval is set by software and can be
changed during runtime, eliminating jumper switch setting.
