Node Usage
sACN in
This node can be used to read one or multiple universes send by sACN.
Parameters:
| Paremeter | Description | Possible Values | Default Value | Mandatory |
|---|---|---|---|---|
| universe | The universe that is meant to be observed. | \d+ (1 to 63999) |
1 |
yes |
| mode | Defines whether the node returns the values of every read sACN package (passthrough mode), or merged values using HTP or LTP. | passthrough, htp, ltp |
htp |
yes |
| output | Defines wether the node sends only changed values or the whole universe. | full, changes |
full |
yes |
| IP-address | IP-Address of the network-interface that should be used for reading from sACN. | \d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\ (any valid ip-address) |
empty | no |
| port | The network port which should be used for reading sACN. | \d+ |
empty (defaults to 5568) |
no |
Output for direct-mode:
| Property | Description |
|---|---|
sequence |
sACN packets are given a packet sequence number so that the receiver can keep the sequence of packets from a given sender. (1 to 255) |
source |
IP-Address of the sender. |
priority |
Priority of the sender. (1 to 200) |
universe |
Id of the universe the package is addressed to. |
payload |
array containing the dmx values as percentage by dmx channel. DMX-Channel 1 starts at key 1, not 0. (Array<number, number>) |
Output for merging-modes (HTP or LTP):
| Property | Description |
|---|---|
universe |
Id of the universe the package is addressed to. |
payload |
array containing the dmx values as percentage by dmx channel. DMX-Channel 1 starts at key 1, not 0. (Array<number, number>) |
sACN out
This node can be used to send one universe using sACN.

1 |
yes |
| source-name | The name for the sACN-sender that should be displayed within the network. | any string below 50 characters | Node-RED |
yes |
| speed | Defines the frequency for sending sACN-packages | once (0Hz), 24Hz, 27Hz, 30Hz, 40Hz, 44Hz |
0Hz |
yes |
| priority | The priority that should be used for the sACN-sender. | \d+ (1 to 200) |
100 |
yes |
| IP-address | IP-Address of the network-interface that should be used for sending sACN. | \d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\ (any valid ip-address) |
empty | no |
| port | The network port which should be used for reading sACN. | \d+ |
empty (defaults to 5568) |
no |
Expected input:
| Property | Description |
|---|---|
payload |
array containing the dmx values as percentage by dmx channel. DMX-Channel 1 starts at key 1, not 0. (Array<number, number>) |
Scene-Controller
This node can be used to record scenes and play them afterwards.
Parameters:
| Paremeter | Description | Possible Values | Default Value | Mandatory |
