The Couplers with cables attached are known as In-line Data bus Couplers.
Compupower provides In-line Data Bus Couplers with Single and Dual Stubs. These Couplers are available with and without internal terminations and are for use in applications where mounting can be accomplished by wiring the Coupler into the harness.
Data Bus Couplers can be supplied with a variety of connectors and cables (10614-9 or MIL-C-17/176-00002) or without connectors for splicing or integrating into harnesses.
Couplers can be ordered with custom cable lengths and a variety of connectors for direct installation on any system. Using In-line Couplers in Harness/Network reduces the number of connectors which significantly improves the reliability.
All resistors are 1Watt per MIL-R-39007 and mounted away from the transformer to minimize heating effects. The transformers are manufactured to MIL-T-21038.
All Couplers are 100% tested and certified. For maximum system reliability, several Couplers can be connected in series (chain linked) as harness with no splices.
