The National Instruments LV-222-555-555 is a PXI MIL-STD-1553 Interface Module designed to provide robust connectivity to avionics databuses. Featuring dual multifunction MIL-STD-1553 interface modules, this advanced avionics databus interface supports up to four channels, allowing simultaneous access to different avionics databuses through any compatible PXI chassis. The architecture consists of a carrier module that facilitates single-lane PCIe connectivity to the host system, and it can host two interface modules, providing flexibility in configuration. The default setup of the LV-222-555-555 incorporates four multifunction channels, which can be independently configured to function as Monitor (MON), Bus Controller (BC), and Remote Terminal (RT) channels. Users have the option to expand the channel count or enable interfacing with ARINC 429 communication protocols by swapping one interface module. The module is equipped with extensive error generation and detection capabilities, along with support for 16 open/GND avionics discrete I/O signals and up to 32 remote terminals. Constructed in a standard 3U form factor and weighing 3.5 lbs, the LV-222-555-555 comes with a user manual and maintenance manual available for download.
