 ⚡DMXin / DMXout call offline dmx file :

How to do ?
1: You need to make a offline playlist file first, In box Offline page, it is easy to create playlist files by dragging and dropping the file name.
2: In BoxSetup page you can change PORT3 to DMXin mode and enable DMXin->Offline or enable DMXout->Offline, You can only choose 1 of 2 between DMXin->Offline and DMXout->Offline function, and set Box DMXAddress to you want, that mean SL04 Box like a lighting fixture.
3: In Offline page make a dmx playlist file and disable AutoPlay.
4: SL04 Box like a lighting fixture, have 3 channels, channels mean:
CH1: value 0-9 Stop, 10-249 Play a dmx file from playlist index with loop, 250-255 loop Play All playlist file.
CH2: value 0-255 = dmx file index in playlist, max 256 files.
CH3: value 0-255 = loop number

About DMXout->Offline: DMXout->Offline like DMXin->Offline, DMXin->Offline used hardware PORT3 interface get dmx data, DMXout->Offline not use box hardware PORT, it's used Artnet universe software PORT get dmx data, support by any software and consoler out Artnet dmx data to call TF card offline dmx files, when enable this function, SL04 box will add one artnet PORT for DMXout offline, now box have 5 Artnet PORT.

For Example:
1: If box dmx address set=1, You want play dmx file in playlist index=3, loop 5 times:
 In your dmx consoler, patch 3 channels fixture light library to dmx address=1, then channel3 push to 5, channel2 push to 3, channel1 push to 11 (10-249 any value), SL04 box then will play index=3 dmx file loop 5 times.
2: Next time, If you want play dmx file in playlist index=7, loop 0 times:
 In your dmx consoler, channel3 push to 0, channel2 push to 7, channel1 push to 10-249 value, like 20, the new value cannot be equal to the old value(11), SL04 box then will play index=7 dmx file once.
3: Next time, If you want play all dmx file in playlist, loop 200 times:
 In your dmx consoler, channel3 push to 200, channel2=start play file's index value, if this value above playlist file index, will play from the first dmx file, channel1 push to 255, SL04 box then will play all dmx file in playlist loop 200 times.
4: If you want stop the playing:
 In your dmx consoler, channel3 not care, channel2 not care, channel1 push to 0-9 value, like 0, SL04 box then will stop playing.
5: Please note: For any different operation, channel 1 must change the current value, and the new value cannot be equal to the old value, the time for any different operation cannot be less than 500ms, so the dmx value does not need to be set to the FADE value.

 ⚡Web SDK, If you can do web pages, then you can develop dmx app, it's so easy!

How to do ?
Way 1:
1: Make your own html, js, css file, copy to TF card root directory.
2: In your html file include our sdk.js like this <script src="../sdk.js"></script>
3: In your js or html call our web sdk.js function senddmx(PORT, buf), send 512 byte dmxdata to box. PORT=0,1,2,3, buf=each port 512 byte dmxdata buf[512]
4: Browse http://2.0.0.44/tf/your.html

Way1 Example source code, web files save in box's TF card:
your.html source code:
<html>
 <head>
 <script src="../sdk.js"></script>
 <script src="./your.js"></script>
 </head>
<body>
This is a WebSDK for test! files save in remote box's TF card.
<button onclick="test()"> Send to Box </button>
</body>
</html>

your.js source code:
var dmxdata = [new Uint8Array(512), new Uint8Array(512),new Uint8Array(512),new Uint8Array(512)]; //4 PORT dmx buf;
function test(){
 for(var n=0; n<4; n++){ //box have 4 PORT
  for(var i=0; i<512; i++){ //each PORT have 512 channels
    dmxdata[n][i] = i; //(byte) all dmx channels value loop to 0-255
   }
   senddmx(n, dmxdata[n]); //call box SDK function send to box
 }
}

Way 2:
SL04 Box as a web server, can supports web cross-domain requests, so you can make beautiful touch webui or web APP on your own tablet or computer or mobile phone, all web files not save in box's TF card, it's save in your local device, In your js or html remote call our web sdk.js function http_senddmx(http_link, PORT, buf), send 512 byte RAW dmxdata to box, or can let your touch webui or APP call TF card offline dmx file through our http API, which can be very powerful.
Web files all save in local device, so you only open local html file then will succeed.
Tips: Copy the contents of the following two files to Notepad, save them as your.html and your.js file names respectively, and then open the your.html with a browser to see the effect.
Way2 Example source code, web files in local device, remote call box web API:
your.html source code:
<html>
 <head>
 <script src="http://2.0.0.44/sdk.js"></script>
 <script src="./your.js"></script>
 </head>
<body>
This is a WebSDK for test! files save in local device.<br>
<button onclick="test()"> Send to Box </button>
<button onclick="set_data(0)"> AllZero </button>
<button onclick="set_data(255)"> All255 </button>
</body>
</html>

your.js source code:
var dmxdata = new Uint8Array(512);
var ht=0;
var port_count=0;
function add(){
 for(var i=0; i<512; i++)
  dmxdata[i] +=2;
 var port = (port_count++)%4; //for change each PORT0,1,2,3
 http_senddmx("http://2.0.0.44", port , dmxdata);
}
function test(){
 if (ht) {
  clearInterval(ht);
  ht = 0;
 }else {
  ht = setInterval("add()",55);//55ms auto add
 }
}
function set_data(data){
 if (ht) {
  clearInterval(ht);
  ht = 0;
 }
 for(var i=0; i<512; i++)
  dmxdata[i] = data;
 for(var i=0; i<4; i++)
  http_senddmx("http://2.0.0.44", i , dmxdata);
}

Please note:
Because the SL04 box has a lot of things to deal with, it is recommended that when calling the box web API, the time interval should be greater than 50ms to send a package, not too often, and leave some free time for the box to process other things.
Tips: RJ45 LAN port uses the DMA function, and the processing speed is faster than that of USB virtual network card, Therefore, it is better to use the LAN network port as much as possible.
