<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 />
