National Instruments 784798-01

The National Instruments part number 784798-01 corresponds to the LV-222-511-511 PXI MIL-STD-1553 Interface Module, designed for robust communication protocols in military and commercial environments. This module supports the MIL-STD-1553 digital data bus protocol, which is characterized by its command-response architecture and time-division multiplexing. The 784798-01 features a single-function, four-channel interface capable of operating as a Bus Controller, Remote Terminal, and Bus Monitor, with user-configurable Remote Terminal (RT) response times adjustable through software settings. The configurable response time, which can be set in increments of hundreds of nanoseconds up to 819 microseconds, allows precise measurement from mid-bit zero crossing of the parity bit to the status word sync. However, users should note that when utilizing error checking, the minimum response time may be influenced by specific requirements for MIL-STD-1553A and MIL-STD-1553B variants. Additionally, this 3U sized module includes 16 TTL-compatible discrete I/O channels and supports application development environments such as NI LabVIEW, eliminating the need for an external power supply by drawing power directly from the PXI host system. The modular design facilitates easy addition, removal, and swapping of modules, promoting efficient system configuration. While the 784798-01 supports essential monitoring features like address filtering, its family counterparts may offer advanced capabilities such as multi-terminal simulation and protocol error injection features.
