MIL-STD-1553 Coupler
Couplers for MIL-STD-1553 Data Bus
Sital’s MIL-STD-1553 coupler is a dual, three-stub coupler.
Each three-stub coupler includes an optional internal bus termination.
The coupler’s made to provide three stubs with termination for bus A and another 3 stubs for B. Alternatively, the two 3-stub couplers may be combined to provide a single 6-stub coupler for one data bus.
The coupler can be provided with optional mounting accessories to fit in a 3U or 6U PCI or cPCI/PXI chases allowing for dense and optimized organization of rack-mounted and portable test systems.
This option is enabling denser as well as the optimized organization of rack mounted testers.
Every connections and termination are enabled via a standard D-Type 25 connector.
When the termination is connected during live messaging, an LED lights up, reflecting bus activity & utilization.
