
Pulse-Width or Period Measurement
–
Each counter can be
configured to measure pulse-width or waveform period. In addition, an
interrupt can be generated upon measurement complete.

One-Shot and Repetitive One-Shot
– A one-shot pulse waveform may
also be generated by each counter. The duration of the pulse and the
delay until the pulse goes active is user programmable. A repetitive
one-shot can be initiated with repetitive trigger pulses.

Programmable Interface Polarity
– The polarities of the counter’s
external trigger, input, and output pins are programmable for active high
or low operation.

Internal or External Triggering
–
A software or hardware trigger is
selectable to initiate quadrature position measurement, pulse width
modulation, watchdog countdown, event counting, frequency
measurement, pulse-width measurement, period measurement, or one
shot.

Digital I/O
–
The IP482 has 6 TTL outputs and 2 TTL inputs available
for use.

High density - Single-size, industry-standard, IP module footprint. Up
to four units may be mounted on a 6U VMEbus carrier board or five
units may be mounted on a PCI carrier board.

Local ID - Each IP module has its own 8-bit ID information which is
accessed via data transfers in the "ID Read" space.

16-bit & 8-bit I/O - Channel register Read/Write is performed through
D16 or D08 (EO) data transfer cycles in the IP module I/O space.

High Speed - Access times for all data transfer cycles are described in
terms of "wait" states. For the supplied IP module example, wait states
are utilized for all read and write operations (see specifications for
detailed information).

8 and 32 MHz Clock Support
– Module supports IP operating clocks of
8 and 32 MHz.
This IP module will mate directly to any industry standard IP carrier
board (including Acromag’s AVME9630/60/70/75 VMEbus, APC8620/21
PCI bus, and ACPC8625/30/35 Compact PCI bus non-intelligent carrier
boards). A wide range of other Acromag IP modules are also available to
serve your signal conditioning and interface needs.
The cables and termination panels, described in the following
paragraphs, represent some of the accessories available from Acromag.
Each Acromag carrier has its own unique accessories. They are not all
listed in this document. Consult your carrier board documentation for the
correct interface product part numbers to ensure compatibility with your
carrier board.
