Compupower Private Limited manufactures In-Line Four Stub Data Bus Couplers with Termination. In-Line Four Stub Data Bus Couplers with Termination is the electronic module where the connection[s] between the Stub[s]/ Node[s] and the Data Bus are made. It consists of Bus In, Bus out connections and at least one stub connection. The stub connection is made using a coupling transformer and two fault isolation resistors on the Data Bus end. The Couplers with cables attached are known as In-line Data bus Couplers. The purpose of the Data Bus Couplers is to prevent a short on a single stub from shorting the main Data Bus i.E. To isolate the main Bus from the terminals, to reduce reflections and maintain signal impedance levels.
Compupower Private Limited is the supplier of Data Bus Couplers and Interface Transformers for MIL-STD-1553B applications. In-Line Four Stub Data Bus Couplers with Termination 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.
