Using its experience in designing ruggedized airborne data acquisition systems, ACRA CONTROL has developed a range of stand-alone IP recorders that capture Ethernet packets from onboard networks. These recorders are built using open industry standard setup protocols, storage media and file formats. They are compact and reliable with a simplified setup, a streamlined configuration and an operating range of -40 to 85°C. The open Ethernet protocol SNMP can be used for setup, status and control.
A PC sees the stored data as a FAT32 volume so the files can be accessed instantly and used without third party software. The files are in the popular open source PCAP file format that can be opened, viewed and post-processed using many third party software applications including Wireshark. They are all powered from standard 28V aircraft power and experience no start up delay due to their microprocessor free operation.
The IP recorder family utilizes different options to meet the needs of different applications. Logging speed is available from 64Mbps to 400Mbps and there are variants with different color and display/mounting configurations. Data is stored on a solid-state hard disk cartridge with a SATA interface or on CompactFlash® card. These can be read directly by a PC with standard connectors and off-the-shelf readers.
