National Instruments 784797-01 PXI MIL-STD-1553 Interface Module
Part Number 784797-01 is the identifying part number for the National Instruments LV-222-511-000 PXI MIL-STD-1553 Interface Module. MIL-STD-1553 is a digital, command-response, time-division multiplexing data bus protocol that is used in military aircraft and other military and commercial applications. This protocol also maintains bus activity logs in a sequential record file that can be analyzed by the user later.
The 784797-01 is a single-function, dual-channel interface module that provides a Bus Controller, Remote Terminal and Bus Monitor operation, and user-configurable RT response time. The user-configurable RT response time allows the user to measure the response from the mid-bit zero crossing of the parity bit to the mid-bit zero crossing of the status word sync. This can be set with the help of software and the value is an integer representing the response time in hundreds of ns up to 819 μs. Note that when error checking is used, the minimum response time can get affected by 3.7 μs for MIL-STD-1553A and 7.7 μs for MIL-STD-1553B. The default value for all the modules is 9 μs. Likewise, the monitoring feature provides filtering for terminal addresses, subaddresses, and concurrent monitoring.
The 784797-01 is a 3U size module that comes with 16 TTL-compatible discrete I/O. Likewise, it features software that helps users install and configure the module. Similarly, it supports application development environments (ADEs) like the NI LabVIEW. Because the module draws power from the host, it does not require an external power source. Also, the modular structure of the module allows addition, removal, and interchanging of the modules easier. Some of the modules in this family, in addition to the 784797-01, include more sophisticated features including protocol error injection (word, gap, and message faults) and multi-terminal simulation (up to 32) with concurrent monitoring. Likewise, they also provide variable transmit amplitude and zero-crossing distortion.
