4 General Description

The intention of the DC-2/MC-1 serial port and protocol communication is for an external connected HOST to control and obtain status from the DC-2/MC-1. The protocol has been designed to focus on two specific goals. The first, is HOST uploading and downloading of DC-2/MC-1 configuration, and system/effect setups. The second, is HOST control of basic user adjustable parameters.(i.e. input, volume, balance…)
