Connectors +


LED Ethernet Controller supports most common connectors such as RJ-45, XLR in/out and SPI connectors for your LEDs. You can also find a slot for SD-Card, DIP switch and buttons for control in stand-alone mode.

LED Strip Studio software license is included with every LED Ethernet Controller 3. In case you would like to control LEC 3 over Art-Net or DMX, you can also use third-party hardware and software.

2 x RJ-45

Allows you to control LEDs via LSS software and Art-Net. Daisy chain is available.

XLR In/Out

Allows you to control LEDs via DMX. DMX daisy chain is available.

SD-Card slot

Allows you to play effects and animations without additional equipment in stand-alone mode.

DIP switch

An easy way to setup IP Address, DMX address and default animation from SD-Card.

All Your LED Controllers

Daisy chaining more devices to share LSS or Art-Net signal through Ethernet cables with an RJ-45 connector. To one LED Ethernet Controller 3 and POWERED you can connect another device and create one line of devices sharing the signal.


See the basic schemes how to correctly daisy chain more devices.



You can use standard 3 pin XLR connectors to share DMX signal or even RJ-45 connector (In user manual, you will find scheme how to do connector with RJ-45 and XLR).
