Mackin. A MIL-STD multiplex data bus system consists of a Bus Controller (BC) controlling multiple Remote Terminals (RT) all connected together by a data bus providing a single data path between the Bus Controller and all the associated Remote Terminals.
Phoenix Logistics provides MIL-STDB multi-coupler harnesses for virtually every major US Military Aerospace data bus requirement. These harnesses combine multiple variations of one, two, three, four, five, and six stub couplers.
In addition, these harnesses employ a variety of connectors and contacts. MIL-STD is a military standard that defines the electrical and protocol characteristics for a data bus. A data bus is used to provide a medium for the exchange of data and information between various systems.
