DATA ACQUISITION
Reliable Acquisition
KAM-500 data acquisition is based on a simple and robust concept – the ‘acquisition cycle’. Finite state machines
are implemented on fixed function FPGAs (Field Programmable Gate Arrays), not software dependent
microprocessors. The FPGA is configured to repeatedly perform the same set of actions so that hardware performs
reliably and in a completely deterministic manner– ‘works once, works always’.
No software, stack or microprocessor
No real-time decisions or interrupts
No operating system (no boot up time)
No analog multiplexers =
simultaneous sampling + no crosstalk
The hardware has been designed for reliability
No potentiometers, jumpers or relays
No SIMS (programmable filters)

High Performance
The KAM-500’s high performance is achieved using an all-digital backplane with a throughput of up to 64Mbps
(4Msps with 16 bits per sample). The KAM-500 supports hundreds of analog channels in a single, stand-alone chassis.
For distributed systems the number of channels increases to thousands. All analog modules have high data integrity
as
Every analog channel has its own antialiasing filter, instrumentation amp at least 16 bit ADC and
programmable digital filter
Digital filtering is applied using FIR and IIR techniques for a wider choice of sampling rates, more accuracy
and repeatability as well as immunity to temperature drifts
All parameters are sampled independently of transmission
Time correlation of sampled data is straightforward as parameters sampled at the same rate are sampled at
exactly the same point in time
Simultaneous sampling occurs across the complete system in every card in every chassis making it
unnecessary to realign or interpolate samples during analysis

Modular, Future Proof
A key concept behind KAM-500 is “any module, any chassis, in any combination”. Modules or chassis can be added
to the system or individually replaced. There are over a hundred modules and variants available and chassis can be
built with any mixture of modules – analog, digital, bus etc. – to meet the specific needs of a program. This
modularity means inventory requirements are minimized and it is easy to modify or upgrade a system by simply
replacing modules that interface to
Sensors
Avionics buses
Audio / video
Serial / parallel data
The ACRA CONTROL solution is highly future proof with new modules added continuously every year that work
with the same KAM-500 chassis. This is reinforced with the proven, easy migration path to new networking and
sensor technologies such as smart and wireless sensor networks.

DATA ACQUISITION
Open
ACRA CONTROL’s product design is based on the iNET-X framework which leverages
open standards for systems management, time synchronization, Data Acquisition Unit
(DAU) configuration and data transmission. It is a complete framework that has been
developed around the core recommendations and technologies outlined in the CTEIP
Integrated Network Enhanced Telemetry (iNET) standard ensuring interoperability for
instrumentation networks. In essence iNET-X
eXtends iNET to ensure high performance and network coherency
eXcels at providing ease of set-up and management for networked DAS
eXceptionally comprehensive statement on protocols and standards
ensuring a future proof system
eXtremely reliable and rugged hardware specification
One key aspect of the iNET-X framework is the metadata layer which is defined as XidML. This is an open XML
metadata standard for the aerospace community that has been developed and published by ACRA CONTROL in
cooperation with industry partners. It provides a vendor-neutral hardware configuration platform that describes how
data is acquired, processed and packaged for transmission, storage or reproduction and facilitates device
interoperability.
Rugged
ACRA CONTROL’s products are designed to operate in the harshest environments for example rotor hubs, engine
casings, fast jet wings and solid rocket boosters. The modules are rugged by design e.g. their small form factor is
inherently vibration resistant. The chassis are fully environmentally qualified for the aerospace environment – please
refer to the environmental specifications section for details. A limited set of modules and chassis are available to
operate in extreme temperatures between -55 to 105ºC, for example on engine casings or launch vehicles.

Bus Monitors
The avionics busses ARINC-429 and high speed MIL-STD-1553 have been joined by commercial standards such as
Ethernet, CAN-bus and FireWire. ACRA CONTROL provides ‘Parsers’, ‘Snarfers’ and ‘Packetizers’ to monitor a wide
range busses in a standardized manner without interfering with the busses operation.

AFDX
Parser - Extracts specific data from a
bus and places it into defined words
ARINC-429
along with status information. Data is

information which can be IP packet wide.
STANAG-3910
TTP bus
Transmitters
ACRA CONTROL’s transmitter modules encode data into a format suitable for transmitting to an external source e.g.
another DAU, a recorder or an RF transmitter. Any chassis can transmit one or more of the following standards:
ARINC-429 / 573 / 717, CAIS, Ethernet, IRIG 106 PCM, MIL-STD-1553, RS-232/422/485. Our compiler ensures that
transmission occurs independently of data acquisition.
Ethernet transmitters with aperiodic packet support do not transmit empty IP packets. PCM encoders designed for
PCMoIP applications have aperiodic packet support and behave very like CCSDS encoders except that any group of
words in the PCM frames can be allocated to a Packetizer.

DATA ACQUISITION
Network Native
ACRA CONTROL has developed reliable high performance Ethernet interface modules and rugged aggregators and
switches that allow the ‘network native’ KAM-500 to be interconnected in an Ethernet network. In such a network,
setup, data acquisition and synchronization occurs over a single Ethernet connection, leading to significant savings in
wiring complexity and weight.
Standard protocols are used for programming (TFTP), health status monitoring (SNMP) and synchronization (IEEE
1588). The managed switches transmit IEEE 1588 PTP packets to synchronize a system to better than 100ns, even
across large distributed systems. There is no adaptive or dynamic switch behavior as the Ethernet data output of the
DAU is predictable and known in advance. This deterministic acquisition and transmission facilitates coherency.
Data from an Ethernet KAM-500 is optimally packetized for Ethernet transmission and recording but can be also be
converted in many other industry standard protocols. This facilitates hybrid system e.g. PCM DAUs can be integrated
into an Ethernet system or Ethernet data can be converted to PCM for telemetering.
