The ACRA CONTROL Difference<br />
ACRA CONTROL’s KAM-500 data acquisition units (DAUs) are driven by hardwired finite state machines making<br />
them extremely reliable. Their compact, low power design makes them ideal for installing in locations that have<br />
limited space. ACRA CONTROL’s DAUs operate in the harshest environments thanks to their MIL-SPEC<br />
environmental ruggedness.<br />
There are over a hundred modules available that support advanced signal conditioning, avionics bus monitoring,<br />
video/audio compression, integrated data logging and multiple output formats; all of which adhere to the “any<br />
module, any chassis, in any combination” rule. This has many benefits including a simple upgrade path and<br />
enabling highly customized systems to be built using COTS product.<br />
The KAM-500 was designed to be ‘network native’ and gathers data with precision synchronization even across<br />
a large distributed system. It can operate in many industry-standard topologies, such as Ethernet, PCM and<br />
CAIS. The KAM-500’s well-proven backplane uses a 100% digital architecture to support a throughput of up to<br />
64Mbps (4Msps with 16 bits per sample) per chassis, aggregating up to gigabit per second throughput for a<br />
network distributed system.<br />
The KAM-500 is based on open and mature standards and protocols for transmission, system synchronization,<br />
management and configuration. The chassis’ modularity yields an exceptionally long useful life with a direct<br />
upgrade path to new technologies that ensures the solution is future proof.<br />
A complete suite of setup and management software that significantly improves setup times completes the<br />
solution by providing integrated tools and an intuitive display environment.<br />

CONTROL benefit aircraft usage monitoring<br />
applications with their flexible interface support and<br />
optional built-in test and solid-state recording. Open<br />
data formats facilitate easy data export to data<br />
analysis software.<br />
Remote Data Concentrator<br />
The KAM-500’s rugged construction and high channel<br />
count to size ratio makes it perfect for acquiring data<br />
from remote locations for delivery to a central point<br />
over a single cable yielding savings in cable weight<br />
and reducing installation design complexity.<br />
Launch Vehicle <strong>Instrumentation</strong><br />
The KAM-500 has proven its reliability and<br />
performance on launch vehicle applications such as<br />
United Launch Alliance’s Delta II and SpaceX’s Falcon<br />
9. Its design is suitable due to its small size, high<br />
channel density and launcher specific benefits such as<br />
transmission black-out buffers for delayed data<br />
transmission.<br />
Flight Data <strong>Acquisition</strong> for Crash Recorders<br />
The KAM-500’s high reliability, live on power-up<br />
functionality and flexible interface support ensures<br />
highly configured systems can be built and later<br />
modified using off the shelf modules that remove the<br />
cost of bespoke designs.<br />
Communications Interface Unit (CIU) for<br />
Unmanned Aerial Vehicles (UAVs)<br />
The KAM-500 can act as a CIU, interfacing between<br />
the Air Data Terminal (ADT) and a host of platform<br />
and payload electronics. Data translation, signal<br />
processing and conditioning, encoding / decoding and<br />
recording can all be delivered in a single, adaptable<br />
unit.<br />

<strong>DATA</strong> ACQUISITION<br />
Reliable <strong>Acquisition</strong><br />
KAM-500 data acquisition is based on a simple and robust concept – the ‘acquisition cycle’. Finite state machines<br />
are implemented on fixed function FPGAs (Field Programmable Gate Arrays), not software dependent<br />
microprocessors. The FPGA is configured to repeatedly perform the same set of actions so that hardware performs<br />
reliably and in a completely deterministic manner– ‘works once, works always’.<br />

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

Compact, Low Power<br />
The compact size and low power requirements of the KAM-500 make it a perfect fit for the majority of airborne<br />
applications. The all-digital system-level design and well-proven, stable and mature backplane architecture, together<br />
with the availability of a wide range of module-level core logic, combine to ensure that no challenge is too great<br />
where the program merits the customization of COTS technology and the schedule can accommodate the<br />

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

<strong>DATA</strong> ACQUISITION<br />
Open<br />
ACRA CONTROL’s product design is based on the iNET-X framework which leverages<br />
open standards for systems management, time synchronization, Data <strong>Acquisition</strong> Unit<br />
(DAU) configuration and data transmission. It is a complete framework that has been<br />
developed around the core recommendations and technologies outlined in the CTEIP<br />
Integrated Network Enhanced Telemetry (iNET) standard ensuring interoperability for<br />
instrumentation networks. In essence iNET-X<br />

eXcels at providing ease of set-up and management for networked DAS<br />
eXceptionally comprehensive statement on protocols and standards<br />
ensuring a future proof system<br />
eXtremely reliable and rugged hardware specification<br />
One key aspect of the iNET-X framework is the metadata layer which is defined as XidML. This is an open XML<br />
metadata standard for the aerospace community that has been developed and published by ACRA CONTROL in<br />
cooperation with industry partners. It provides a vendor-neutral hardware configuration platform that describes how<br />
data is acquired, processed and packaged for transmission, storage or reproduction and facilitates device<br />
interoperability.<br />
Rugged<br />
ACRA CONTROL’s products are designed to operate in the harshest environments for example rotor hubs, engine<br />
casings, fast jet wings and solid rocket boosters. The modules are rugged by design e.g. their small form factor is<br />
inherently vibration resistant. The chassis are fully environmentally qualified for the aerospace environment – please<br />
refer to the environmental specifications section for details. A limited set of modules and chassis are available to<br />
operate in extreme temperatures between -55 to 105ºC, for example on engine casings or launch vehicles.<br />

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

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

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