The Mn664-2000L includes an ARINC-664 bus interface module, a processor, power supply, and an IEEE 1588 time and Ethernet interface module that also functions as an overhead card (MGPI-500-1).
The Mn664-2000L is a miniature networked encoding unit that timestamps and processes incoming ARINC-664 data and sends packetized data to designated nodes on an Ethernet network. Its ARINC-664 (AFDX) data bus interface module receives data from an ARINC-664 avionic switch.
Each fiber optic interface transmits and receives using different wavelengths on the same physical fiber (Note: the transmit path on the Mn664-2000L is permanently disabled). The interface performs integrity and management per ARINC-664 part 7 and all incoming messages are time-tagged with IEEE 1588 time using hardware at the interface. Integrity and redundancy filtering capability can be disabled.
The Mn664-2000L outputs up to 50 Mbps of data or 50,000 data packets (whichever is slower) through its 100BASE-T Ethernet output interface.
