Features
• Transformer and Direct-coupled
• Up to 4 Channels per Quadraplex Card
• Up to 60 Channels per System
• Timing Accuracy’s to 20 microseconds
Introduction
The 1553 Input and Output modules support the full 50,000 word/second data rates of MIL-STD-1553, A and B. The 1553 daughterboard interface cards plug into the Quadraplex board in both the airborne and laboratory chassis. Full software support is provided for both transformer-coupled and direct-coupled interfaces to the bus.
The MIL-STD-1553 input and output interface boards also support short-stub and long-stub coupling as well as the ability to filter data with subaddress and remote terminal-level label selection.
Up to 60 channels of MIL-STD-1553B with 20 microsecond timing accuracy are supported with the system architecture.
