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, connects 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 is the base dual 3-Stub coupler, ready for panel mounting. To mount the coupler, secure it via either the four mounting holes or the DB25F jack screws. The coupler is also available mounted to a standard PC bracket (Item# CPLR1553STL-06-PC) or mounted to a standard 3U bracket (Item# CPLR1553STL-06-PXI) for integration inside a cPCI or PXI enclosure. The coupler only utilizes a back panel location and does not interface with internal system slots.
