This disclosure describes a system that implements a multi-channel command and data processing device for multichannel data processing and transmission systems that are designed to connect to different types of data sources and sinks and describes a device configured to implement a novel endpoint parameter management architecture for generic devices. The system uses a multi-channel command and data processing device with one or more inputs and one or more outputs, with a processor and a memory, in communication with a data storage that manages endpoint parameters of one or more input devices and one or more output devices. The system further includes a data terminal and a plurality of endpoints.
