//  node simpleReceiveValue.js channel                     //
//      channel: number from 1 - 48                        //
//                                                         //
//  node simpleReceiveValue.js ip channel                  //
//      ip: ip of the mixer e.g. 192.168.0.100             //
//      channel: number from 1 - 48                        //
