connect, set channel 1 to 255, disconnect.
var options =host: '172.16.23.15'var artnet = options;// set channel 1 to 255 and disconnect afterwards.artnet;
The set method can set multiple channels at once:
Use an array to set subsequent channels...
// set channel 100 to 10, channel 101 to 20 and channel 102 to 30artnet;
...if you want to keep certain channels unchanged set them to null
// set channel 50 to 255 and channel 52 to 127artnet;
you can omit the channel, it defaults to 1
// Set channel 1 to 255 and channel 2 to 127:artnet;
Additionally, you can send trigger macros to devices.
// Send key 3, subkey 1 to all devices.artnet;// Send key 2, subkey 71 (the letter 'G') to ArtNet Devices responding to 0x6A6B.artnet;
This lib throttles the maximum send rate to ~40Hz. Unchanged data is refreshed every ~4s.
- host (Default
- port (Default
- refresh (millisecond interval for sending unchanged data to the Art-Net node. Default
- iface (optional string IP address - bind udp socket to specific network interface)
- sendAll (sends always the full DMX universe instead of only changed values. Default
set( [ [ uint15 universe , ] uint9 channel , ] uint8 value [ , function(err, res) callback ] )
set( [ [ uint15 universe , ] uint9 channel , ] array[uint8] values [ , function(err, res) callback ] )
Every parameter except the value(s) is optional. If you supply a universe you need to supply the channel also. Defaults: universe = 0, channel = 1
Callback is called with (error, response) params. If error and response are null data remained unchanged and therefore nothing has been sent.
trigger( [ [ uint15 oem , ] uint9 subkey , ] uint8 key [ , function(err, res) callback ] )
Sends an ArtNet ArtTrigger packet. ArtTriggers are typically device specific and perform functions like starting and stopping shows.
Every parameter except the
key is optional. If you supply an
oem, you need to supply a
Callback is called with
(error, response) params.
triggers are NEVER throttled, as they are time sensitive. They are always sent immediately upon processing.
Closes the connection and stops the send interval.
setHost( string host )
Change the Art-Net hostname/address after initialization
setPort( number port )
Change the Art-Net port after initialization.
Does not work when using the broadcast address
