Overview
The PCI-SynchroTM Series" product line are
full size PCI 2.2
compliant synchro,
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.
Differing converters
may be mixed to minimize
real estate of any type. Both industrial and COTS military grade (extended)
temperature range
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
noise, inductive
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
access.
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
particular application. |
 |
| The demonstration
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. |

Description
The PCI-SynchroTM cards
facilitate up to 8 isolated input chanels, and are 1-8 continuously
tracking synchro or resolver toIBM PC/ATTM card
converters, employing type 2 ratiometric tracking converters for high
performance applications.
They will accept any group of upto 8 individual, or 4 sets of paired
multispeed; 3-wire Synchro,
or 4-wire Resolver inputs, or
2-4 wire LVDT/RVDT inputs; over a frequency range of 50Hz.
to 10KHZ., and convert them into 10-16 bit words of natural binary
data.
Data is addressable in a long
word 32 bit format over
the IBM PC/ATTM backplane.
Data made available to the bus is continuously updated (tracking)
without interruption; output data
is accurate, monotonic, and always fresh up
to the maximum tracking rate of the converter.
When the address is applied, and normal bus variables are set; the
converters data bits are
latched simultaneously into separate buffered registers to prevent false
reads.
A Forced Self-test feature is optioned "-WS" that
allows on program command an internal disconnect of inputs to read a 30o fixed
analog test.
A
continuous Built-In Test (BIT) output representing the tracking mode,
Loss of signals, Loss of Reference, for
status report are provided for each input channel.
No external transformers, modules
or signal conditioners are required.
The synchro/resolver converters used featureinternal solid-state
or Transformer Isolated Scott
T's that accept direct
field voltage inputs.
Isolation
Transformer isolated units
are completely isolated
from each other and the backplane for
all the reference and signal lines.
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
loops, ground induced noise, differing potentials, ground interjected
spikes, and ghostly filed noise that so frequently takes down entire
systems.
Bus Powered
No external supplies required ! All
units are available as completely
bus powered via the PCI backplane or
as external inputs for the +12VDC
supplies. Power required is +12,
+3, and +5VDC, and the source is for the +12VDC
is strap selectable for power sourcing via the ISA backplane or as
external power via the I/O connector.
Options currently available include: DC velocity outputs, internal
reference supplies, quadrature pulse train outputs, high reliability and
mil-grade extended temperature range units. Units with on-board
DC-to-DC converters also available.
Additionally, PC/AT cards can be configured to meet
particular OEM requirements. Many perspective custom applications can
be configured with 100% standard product. |

Description
The PCI-SynchroTM output
channels are complete PCI
to Synchro and Resolver output
converters used for self-test, simulation, and control in
military and industrial applications.The PCI card is
populated by 1-3 Industry
Standard Digital to Synchro and/or Digital to Resolver
Converters, CT's or CDX's mixed
as specified for the application.
32 Bit long word level double buffered inputs are
provided on each
channel and
addressable via independent or successive address.
The true 32 Bit
architecture allows
the converters to be written to as single word writes, without any
ear of low-byte/high-byte ambiguities.
All of these converters feature virtually
indestructibel short-circuit proof outputs, overvoltage, and
transient protection, internal solid-plate heat sinks, and
automatic thermal cutoff.
Complete transformer isolation is porvided on all
reference inputs ad signal outputs to: eliminate ground loops,
differing potentials, and to keep any high voltage transients
from affecting the PCI backplane.
Both low cost
"DSL/DRL Series" and referenced powered "DSP Series" converters are
offered to drive on board loads
up to 4.5VA and
external "booster amplifiers" are available to drive loads
up to 150VA.
DSL/DRL TYPE CONVERTERS
The DSL/DRL series
are low cost
models that are
powered from either + 15VDC
or optionally +12VDC
supplies. The DC supply source may ve field selected as sourced
by and external input or Bus
Powered for the PC/AT backplane .
The power supplies should be verified as capable of providing
the required current.
Stadard +12VDC
units drive 1.2VA loads, and standard +15VDC
units drive 1.5VA loads. Higher drive models are available.
Frequencies of 400Hz. and higher require no external
components , and two different types of output transformers are
offered for 50-60Hz. units.
These units occupy one full size with a singlewidth slot.
Absolute value, vector units "active" Differentials, Dynamic
Rotators, & 2-10HZ. models are available as standards for motor
control apparatus and realtime simulators.
DSP TYPE CONVERTERS
DSP series 60Hz. units don't require any external
transformers, and drive all 50, 60, & 400 Hz. loads. |

The DSP
series derives the output power
from the reference (RH,RL) input
and requires no +15
or +12VDC
supplies. This series features a very efficient, internal pulsating
power supply that converts the reference input into a high-power,
angle-weighted, synchro output format.
400Hz. DSP units drive
up to a full 4.5VA load, and 60Hz. units drove a full 1.5VA load
direct without requiring external output transformers.
The DSP units occupy one full size doublewidth slot (DSP modules are
.8H).OTHER CONVERTERS
By looking at the model selection guide you will notice the PCI
Series models, allow the choice of both Read and Write type Converters.
Units with Isolated Digital to Analog, or LVDT converters, multispeed
conversion, Vector Generators, Control Transformers, and Differentials
etc...can be configured by requesting "IBB Series Extended Model
Selection Guide" from the factory. |
