National Instruments 784801-01 Interface Module

Part number 784801-01 from National Instruments is the descriptive part number for the LV-222-555-555 Interface Module. Boasting 2 core I/O sites, this Avionics Databus Interface Module supports the MIL-STD-1553 protocol, which is specifically designed for military and commercial applications. Each core of the 784801-01 boasts 64 MB of memory and is equipped with 8 bidirectional TTL discrete I/O. In addition, these cores are each equipped with 2 LED indicators that are user controlled- providing visual insight into the status of the module at a glance.

The power requirements for the device depend on the power rail and whether or not both cores are being used. When both cores are active, the 784801-01 has a typical power draw of 5.9 W for +3.3 V and a typical current of 7.7 W for +12 V.

Since the 784801-01 is designed specifically to support the MIL-STD-1553 protocol, it boasts a few model-dependent features. These include amplitude controls, playback (with errors), hardware controlled transmit scheduling, and more. The 784801-01 is capable of sequential monitoring and time stamping- allowing the user to quickly visualize and analyze data with in-depth time stamps.

Designed with a standard 3U PXIe size, the 784801-01 weighs just 3.5 lbs. (1.6 kg). Built to withstand diverse environmental conditions, the device should only be operated within temperatures ranging from -40 to 85° C. When not being used, the 784801-01 can be safely stored in temperatures spanning from -55 to 100° C. When either operational or not in use, the module should be kept in conditions where the noncondensing humidity stays within the range of 0 to 95%.
