Communication command system and method

摘要

A communication command system controls communications between equipment having sub-devices for outputting different types of communications. A bus with different channels is connected to the input/output ports of the equipment to send communications back and forth between the equipment. A switch switches the connection between the sub-devices and the bus channels. A command master commands the switch to switch a particular sub-device to a particular bus channel and, in this manner, communications are set up between sub-devices of different equipment.
