The PCI-SynchroTM Series" product line are
full size PCI 2.2
resolver, and LVDT I/O cards, and resolver-sensor card sets are used as
absolute encoder systems.
These cards are ideally suited for both industrial and COTS
military concerns using any PCI bus compatible computer for simulation,
ATE, "Absolute" position sensing and motion control, coordinates &
process control, navigation, GPS, data acquisition, radar, ships speed
indicators, antenna & targetting applications.
The PCI-SynchroTM Series
converters provide up to 4 and 8
channels of Isolated
Synchro/Resolver LVDT/RVDT orabsolute
encoder interface on a
single, standard full size 2 PCI printed circuit card.
Computer Conversions' full line of standard, proven "whole" Synchro/Resolver
input and output type converters, CT's
and CDX's etc ... are
used to populate the same standard PCI compliant CCA's.
may be mixed to minimize
real estate of any type. Both industrial and COTS military grade (extended)
versions are available.
100% Transformer Isolation is
offered for all AC I/O,
and various Isolated DC converters are available as standard product,eliminating concerns
for ground-loops, ground
interjected (intermittent and ghostly) field
surges, differing potentials, and high
voltage field transients from effecting the
card itself, the sensitive
PCI bus backplaneand any
other device or system
sharing these signals.
Maximum versatility has
been employed on all PCI-SynchroTM products
to assure the universal compatibility in adressing, timing, system, and
specific computer hardware,
software, and backplane independence.
All PCI-SynchroTM cards
are configured with full plug and play capabilities, and are ideally
suited to real-time applications because there is no PCI-Bus latency.
The interface is a solidly-reliable / high-speed, true 32
bit "Long-Word-Level" register
Status registers are
provided for various levels of fault
indication, Built-in-Test (where
applicable), and configuration criteria.
A sample demonstration program written in Visual C++ is provided with
source code, which may be easily modified by the user for his/her
program (with source code) is provided for Out-Of-The-Box
testing, without any user programming required.
All cards may be
user configured completely
Bus-Powered, with no
external power supplies required. Power souirce jumpers are provided
to select the +/- 12vdc power source as "Bus-Powered" or as external
inputs via the onboard terminal block.
The use of "proven whole converter" modules assures the user of
garunteed systen accuracy and dynamics ability, long term conversion
integrity and stability.
All wiring is made through standard or 50 pin "D" style connectors.
Isolated D-A/A-D Converters, Digital Modulators, Demodulators, AC
Referencs Supplies, & related function converters may be used with these
cards The availability of synchro/resolver I/O on the PCI Bus, allows
the user to configure his systems with resident test ability, switched
manual or automatic self test, and simulation type programs.

This completely isolates the card and effectively the whole
computer from all field wiring, and especially from any other device
sharing these signals: eliminating concerns over; troublesome ground
