National Instruments 784800-01 PXI Interface Module

The 784800-01 from National Instruments is the identifying part number for the LV-222-555-000 PXI Interface Module. As part of the OmniBus2 product line from Astronics Ballard Technology, the model name for this module is the MIL-STD-1553 interface module. Ideal for military and aerospace applications, the rugged 784800-01 facilitates connection from a PXI chassis to the MIL-STD-1553 databus even in harsh environmental conditions. The module features 2 core I/O sites which are each supported by 64 MB of memory, allowing for plenty of space for a variety of configurations. The power draw of the device is +3.3 and +12 VDC.

Each core of the 784800-01 is equipped with 8 bidirectional TTL discrete I/O lines, allowing it to both transmit and receive signals. In addition, each core features an LED indicator that is user-controlled, providing insight into the status of various settings with just a glance. The interfaces supported by the module include BC/RT/MON functions, message filtering, time stamping, and more. The 784800-01 module is capable of hardware-controlled transmit scheduling, and is able to support up to 2 dual-redundant channels for each core.

The 784800-01 is compatible with various software options such as Windows CoPilot and the BTIDriver API. Physically, the device has a standard 3U form factor, measuring (100 x 160 mm). It weighs in at an easily portable 3.5 lbs. (1.6 kg). Built to last even in harsh environments, the 784800-01 has a wide operating temperature range of -40 to 85° C. When in storage, it can withstand and even wider range of temperatures, spanning from -55 to 100° C. For both operating and nonoperating conditions, the module has a noncondensing humidity tolerance ranging from 0 to 95%.
