ENTTEC ODE MK2を使ってNode-REDからsACNでDMX機器を操作するメモ2（改良版）
全チャンネルの値を配列でmsg.payloadで送る
公式サイトにでているfull universeに配列でデータを送る方法です。
このフローでは、Injectノードから調光レベル(dimLevel)を数値でおくり、その後のfunctionノードで、器具台数分の全チャンネルにdimLevelを書き込み、ENTTEC ODE MK2に送っています。
var dimLevel = msg.payload;
var fixtureNumber = 50;
var DMXValues =[];
for(i=0; i<(50*3); i++){
DMXValues[i]= dimLevel;
}
// globalに器具のDMXValuesをセットする
global.set('DMXValues',DMXValues);
msg.topic = "1/1";
// (string: Universe/Channel)
msg.payload = DMXValues;
// DMX values
//msg.payload = value;
return msg;

msg.payloadで１chづつ送る
こちらの方法です。
transitionも入れることができます。
msg.payloadで送る際、まずは、配列でDMXチャンネル分のdimLevelをDMXValuesで準備。
あとは1chづつmsg.payloadでDMXのレベルを送るようにしています。
var dimLevel = 255;
var fixtureNumber;
var DMXValues = global.get('DMXValues');
var channel = msg.counter+1;
msg.payload = {
"universe": 1,
"channel": channel,
"value": DMXValues[channel]
}
msg.counter = msg.counter +1;
return msg;
