PCA-6144V User's Manual
Introduction
The PCA-6144V is an all-in-one single board 486 computer that includes
an on-board SVGA controller. It packs all the functions of an industrial
computer, including display capabilities, on a single half-size card. The
PCA-6144V is fully PC/AT compatible, so your software will run without
modifications.
The on-board VL-bus SVGA controller uses the Trident TGUI 9440
chipset with 1 MB video memory. This chipset, used with the local bus,
enables 32-bit graphic throughput at up to 33 MHz. The TGUI 9440 also
offers Windows graphics acceleration. These features are excellent for
display-intensive applications.
Another feature of the PCA-6144V is the inclusion of a fast VL bus
enhanced IDE controller. This controller supports mode 4, which enables
data transfer rates in excess of 16 MB/second. Up to two 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 high-speed serial ports with 16C550
UARTs, one bidirectional SPP/EPP/ECP parallel port and a floppy drive
controller. In addition to the 486's 8 KB of on-chip cache memory, the
PCA-6144V includes an extra 128 KB of second level cache memory on-
board.
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
timer interval of the watchdog timer is set by software, eliminating jumper
switch setting.
The PCA-6144V provides two 72-pin SIMM (Single In-line Memory
Module) sockets for its on-board system DRAM. These sockets give you
the flexibility to configure your system from 1 MB to 64 MB of DRAM
using the most economical combination of SIMMs.
