Stand-alone IP recorders from ACRA Control capture ethernet packets from onboard networks. The compact recorders feature a simplified setup, streamlined configuration, and operating range of -40 to +85°C. The open ethernet protocol SNMP can be used for setup, status, and control. Data are stored on a solid-state hard disk cartridge with a SATA interface or on a Compact Flash card formatted as a regular FAT32 volume. The files can be accessed instantly and used without custom software via a PC with standard connectors and off-the-shelf readers. The files are in the open-source PCAP file format that can be opened, viewed, and post-processed using various third-party software applications including Wireshark. They are powered from standard 28-V aircraft power and experience no start-up delay.
