DATA ACQUISITIONReliable AcquisitionKAM-500 data acquisition is based on a simple and robust concept – the ‘acquisition cycle’. Finite state machinesare implemented on fixed function FPGAs (Field Programmable Gate Arrays), not software dependentmicroprocessors. The FPGA is configured to repeatedly perform the same set of actions so that hardware performsreliably 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)

The hardware has been designed for reliability

� No potentiometers, jumpers or relays� No SIMS (programmable filters)

High PerformanceThe 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 integrityas

� Every analog channel has its own antialiasing filter, instrumentation amp at least 16 bit ADC andprogrammable digital filter

� Digital filtering is applied using FIR and IIR techniques for a wider choice of sampling rates, more accuracyand 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

Compact, Low PowerThe compact size and low power requirements of the KAM-500 make it a perfect fit for the majority of airborneapplications. The all-digital system-level design and well-proven, stable and mature backplane architecture, togetherwith the availability of a wide range of module-level core logic, combine to ensure that no challenge is too greatwhere the program merits the customization of COTS technology and the schedule can accommodate thecorresponding lead-times.

* design concepts

Modular, Future ProofA key concept behind KAM-500 is “any module, any chassis, in any combination”. Modules or chassis can be addedto the system or individually replaced. There are over a hundred modules and variants available and chassis can bebuilt with any mixture of modules – analog, digital, bus etc. – to meet the specific needs of a program. Thismodularity means inventory requirements are minimized and it is easy to modify or upgrade a system by simplyreplacing 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 workwith the same KAM-500 chassis. This is reinforced with the proven, easy migration path to new networking andsensor technologies such as smart and wireless sensor networks.

DATA ACQUISITIONOpenACRA 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.

RuggedACRA 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 MonitorsThe avionics busses ARINC-429 and high speed MIL-STD-1553 have been joined by commercial standards such asEthernet, CAN-bus and FireWire. ACRA CONTROL provides ‘Parsers’, ‘Snarfers’ and ‘Packetizers’ to monitor a widerange busses in a standardized manner without interfering with the busses operation.

PRODUCT GUIDE

TransmittersACRA 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 thattransmission occurs independently of data acquisition.Ethernet transmitters with aperiodic packet support do not transmit empty IP packets. PCM encoders designed forPCMoIP applications have aperiodic packet support and behave very like CCSDS encoders except that any group ofwords in the PCM frames can be allocated to a Packetizer.

1 requires external device

� Parser - Extracts specific data from abus and places it into defined wordsalong with status information. Data istriple buffered to ensure the data remainscoherent. A MIL-STD-1553 parser issometimes referred to as IRIG-106Chapter 4 monitor.

� Snarfer – Places traffic and tags, alongwith content identifiers, into a FIFO thatensures data is not lost if read fastenough. For MIL-STD-1553 snarfing issometimes referred to as Chapter 8 orAll-bus monitoring.

� Packetizer – Coherently embedsmultiple whole messages / frames /packets of various lengths in an IP packet.Because traffic and tags can be inferredfrom the location in the packet payload,content identifiers are not required andtherefore less overhead / bandwidth isrequired. There are also overhead savingswith respect to time and statusinformation which can be IP packet wide.

DATA ACQUISITIONNetwork NativeACRA 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.
