Description
What can LEC 3 actually drive?
Every pixel installation starts with one question. What will actually drive the LEDs? LEC 3 answers it for four SPI lines at once.
The controller handles up to 4096 addressable RGB pixels. In RGBW mode the limit is 3072. Each of the four powered outputs runs 1024 RGB pixels.
Need more? Add LSS Distributors and one controller reaches 8096 pixels. Moreover, several LEC 3 units share a single Ethernet switch. As a result, installations of 50 000 pixels and more stay on one network.
Four ways to run the show
First, Ethernet. LED Strip Studio software sends video, live stream and generated effects in real time. You can also build a full show on a timeline and sync it to music.
Second, Art-Net™. LEC 3 works as a direct pixel output for Madrix, MadMapper or MA Grand consoles. Each output accepts up to seven universes.
Third, DMX512. The 3-pin XLR input and output work in pixel mode. Alternatively, DMX simply triggers animations stored on the card.
Finally, stand-alone. The controller plays up to 255 animations from the micro SD card, or a 16-step playlist. You switch files by buttons, DIP switch or web interface.
How do digital and analogue lights share one timeline?
DMX Out runs in Out and Through mode. Therefore the same controller also feeds analogue strips, PARs and other DMX fixtures. Digital and analogue lighting stay on one timeline.
Setup and testing in a browser
Type the device IP into any browser. By default it is 192.168.1.147. Then set LED IC type, colour order, brightness ceiling, universes and playlists. A phone works just as well as a laptop.
Built-in test patterns confirm wiring before the strips go up. Firmware updates arrive from the SD card, or through the web interface.
Power, protection and mounting
The 5–24 V DC input matches your strip voltage. Each output carries up to 5 A. Above that, a resettable polyfuse protects the board instead of letting it burn.
Two RJ-45 ports share an internal switch. Consequently, controllers daisy-chain without extra hardware.
The body measures 142 × 69 × 44 mm, or 207.2 mm across the brackets. L-brackets and a DIN rail mount are included. Designed for indoor use.
