FUNCTIONAL
DESCRIPTION
This
is a 96 line digital input/output card with counter/timer
capabilities designed for use in high I/O density application
requirements. I/O connections are made via four 50-pin header
connectors. The card is 12.25 inches long (312 mm) and may
be installed in any full-length 5V PCI-bus (or PCI-X bus)
slot in X86 type PC's.
The card contains four type 8255-5 Programmable Peripheral
Interface (PPI) chips. They can be programmed to accept
inputs or to provide outputs on three 8-bit ports: designated
Ports A, B, and C. Port C can be further divided into two
4-bit ports.
Each* I/O line is buffered by a type ABT245 tristate buffer
transceiver capable of sourcing 32 mA or sinking 64 mA.
The buffers are configured under program control for input
or output use according to direction control signals from
the control register inside the PPI. 10K Pull-ups (to +5
VDC) on the card assure that there are no erroneous outputs
at power-up until the card is initialized by system software.
*For operation in 8255 Mode 1, no buffers are installed
on port C Hi or Lo
COUNTER/TIMERS
There
are three 16-bit down counters with each I/O pin brought
to the connector can be field configured by on board jumpers
in a variety of useful ways to measure frequency, count
pulses, measure pulse width, generate frequencies, etc.
UTILITY
SOFTWARE
DLL's,
Windows setup programs, and a suite of sample programs
are provided on CD with the purchase of the card.
