The VM1553 is an IEEE1386 compatible PMC offering up to four channels of STANAG 3838 or MIL-STD-1553 compatible connectivity. The VM1553’s compact, modular form factor gives it many uses for embedded solutions in both air and conduction cooled environments and, combined with a Varisys PMC carrier can be easily used in a laboratory. The module is compliant with MIL-STD-1553A, MIL-STD-1553B and STANAG 3838 protocols. Each channel can be individually configured for Bus Controller (BC), Remote Terminal (RT), Bus Monitor (BM) operations or Extended RT/BM. Varisys’ flexible design approach means that the VM1553 can be configured for direct or transformer coupled interface via the same pins on the P14 connector. The PCI interface is flexible with either 3.3 or 5V signaling. The Varisys design has given the VM1553 a low power requirement of less than 2W for a single 1553 channel.
The VM1553’s ability to operate from -40°C to +85°C make it ideal for use in data recording, monitoring and display either in black box systems or embedded mission computers. Typical applications for the VM1553 include Avionics, Radar, Sonar, Data Recording in hard real time environments such as aerospace, naval or land based platforms.
The VM1553 is fully supported with an advanced high level Core Library Application Programming Interface (Core Library API) providing a flexible, cost saving solution. The design concept of the Core Library API is that it provides a consistent interface across all Operating Systems and hardware architectures. The Core Library API facilitates the porting of applications to new hardware solutions with very minimal changes. The software support that we offer provides full device and board level Built In Test (BIT) functionality as well as full Endian management, hardware interrupt support, and chipset management. The Core API provides an optional high speed data offload engine, designed to gather bus monitor or remote terminal data from chipset memory to a host storage area.
