The CPLR1553STL-06 is a dual, three stub MIL-STD-1553 coupler with optional internal termination. The coupler is designed to provide 3 stubs with termination for bus A, another for B, or concatenated to a single 6 stub coupler for a single bus. The coupler offers a unique, innovative low profile mechanical structure that supports panel mounting, as well as installation in PCI or 3U cPCI (PXI) enclosures. This feature enables denser and optimized organization of rack mounted testers. All connections and termination are enabled via a standard DB25F connector. When termination is engaged, an LED lights up during live messaging, reflecting bus activity and utilization.
The dual 3-stub coupler connects via the pins of the single DB25F connector. The upper row, pins 1 through 13, connect to the high-side of the MIL-STD-1553 wires. The lower row connects with the complementary wires of the MIL-STD-1553 bus. If a single 6-stub coupler is required, use a jumper to connect pins 6 and 8, as well as pins 19 and 20. For all configurations, only one termination is required at the end of the coupler for proper MIL-STD-1553.
This coupler is mounted to a standard 3U bracket for integration inside a cPCI or PXI enclosure. The coupler only utilizes a back panel location and does not interface with internal system slots. The coupler is also available mounted to a standard PC bracket (Item# CPLR1553STL-06-PC), or as a base model, ready for panel mounting (Item# CPLR1553STL-06-PNL).
