Extended temp interfaces for PC/104 systems from SBS Technologies

Two versions of extended temperature MIL-STD-1553 interface cards for a PC/104 backplane have recently been introduced by SBS Technologies Inc.—each based on an advanced, high-speed digital signal processor (DSP).


ABI-PC104-2 (shown) and ASF-PC104-2 interface boards include host processor device drivers and application programming interfaces.

Two versions of extended temperature MIL-STD-1553 interface cards for a PC/104 backplane have recently been introduced by SBS Technologies Inc .—each based on an advanced, high-speed digital signal processor (DSP). Advanced Bus Interface ABI-PC104-2 interface card offers flexible, full-function dual-channel and redundant architecture, operating in a -40 to 85

ABI-PC104-2 interface card provides a PC/104 bus system with a 1553 interface, which includes 1553A/1553B selections, pointer-driven transmit/receive buffers, and extensive programmable-event interrupts. ABI architecture allows developers to configure this card as a Bus Controller (BC), Bus Monitor (BM), or Remote Terminal (RT)– concurrently or independently, depending on the application, says SBS Technologies. For applications that require only one of the BC-to-RT, RT-to-BC, or RT-to-RT functions, ASF-PC104-2 interface card gives embedded developers a more economical choice. The card’s 128 KB dual port RAM allowshost processor access to set up, monitor, and change 1553 interface data structures at any time.

"We added extended temperature robustness to our basic PC/104 platform to meet the needs of today's demanding 1553 applications," says Dave Wessing, vice president of SBS Technologies Avionics Group. [MIL-STD-1553 refers to a widely used standard of military origin that defines electrical and protocol characteristics for a data bus. It is analogous to LAN (local area network) protocols in the PC and industrial automation world.]

ABI-PC104-2 and ASF-PC104-2 extended temperature interfaces are available now. Consult the manufacturer for pricing, which depends on configuration and quantity.
