Sital Announces the Release of the 2nd Generation Avionics Bus Tester – the MultiComBox

Sital Technology, the world leader in Mil-Std-1553 IP cores and products, is expanding its product base with the release of the 2nd generation of its Mil-Std-1553 bus tester – MultiComBox™.

The MultiComBox™ unit provides two dual-redundant MIL-STD-1553 channels, as well as four (4) serial channels and a synchronization channel for synchronizing other test equipment with 1553 protocol data. MultiComBox™ enables full MIL-STD-1553B testing, simulation and bus analysis capability in a very compact and self-contained unit. The unit connects through a USB 2.0 interface to any host system and supports a concurrent Bus Controller (BC) and up to thirty-one Remote Terminals (RT) with Bus Monitor (MT). Full error injection capability’s available in RT & BC modes, with full error detection in MT, RT, and BC modes. The tester can handle real-time data, creating a unique option for a complete Mil-Std-1553 real bus simulation system.

Special care was taken with the unit’s power consumption in order to enable operation from the low-power USB port of any standard PC, including laptop computers, without any external power source.

MultiComBox™ is supplied with improved Windows GUI – MuxMonitor™ and MuxSim™ – which are user-friendly and intuitive software tools for traffic generation, monitoring and analysis of Mil-Std-1553 bus. Working in conjunction with the unit, MuxMonitor™ can monitor messages, frames and errors and analyze the status of each unit and frame on the bus. It’s providing filters and triggers for displaying and monitoring of recorded data. Also, recorded frames can be exported as CSV, XML and other file formats for future use or for interacting with other programs. MuxSim™ can manage and simulate all traffic on the bus. It can handle a large number of Mil-Std-1553 frames, which can be inserted by the user, recorded from the bus or imported from XML files. To facilitate the test, MuxSim™ is able to simulate 1553 RTs, thus allowing the user to test the full ICD (Interconnect Control Document) without needing to connect every LRU physically. The user easily can pick which units are to be simulated and which units are real.

“The new MultiComBox™ is a great step forward for Sital” said Duli Yariv, Sital’s vice president for marketing. “our proven 1535 IP cores technology enables us to create low-cost yet high-value products, and this tester is just the first of many solutions which we are about to release to the market” he added. Sital’s founder and chief engineer, Ofer Hofman, said: “utilizing IP cores, FPGA technology and our flexible analog transceiver design enables us to reduce the size, cost and power consumption of the unit. It also provides the flexibility which is required for supporting more features and bus protocols like H009, PP-194 and others.”
