Daisy-chain up to 32 units on a single SPI output of your <a href=\"\/lec-3\/\">LEC 3<\/a> or <a href=\"\/spi-matrix\/\">SPI MATRIX<\/a> controller, and every hanging lamp, strip segment or object gets its own independent SPI LED output.<\/p>\n<h2>Why an SPI signal splitter instead of more controllers?<\/h2>\n<p>Lighting a hundred hanging lamps usually forces one of two bad choices: buy more controllers for more physical SPI outputs, or push raw SPI data from one object to the next and watch the signal fall apart after a few metres.<\/p>\n<p>Between SPI LAMP 2 units the data runs as a differential LSS strip 2 signal at 2.5 Mbps over ordinary Cat5e cable, so units can sit up to 100 metres apart without signal loss. Those RJ-45 sockets carry our protocol only \u2014 never plug one into a computer network.<\/p>\n<h2>Setup on the device, in two minutes<\/h2>\n<p>The display and four buttons turn commissioning into a two-minute job on site. Choose the IC type, set how many pixels this unit consumes, then read back input voltage, frame rate and firmware version. Built-in test patterns prove the strip works before anyone calls it a fault. The same settings can be pushed from a SpiLamp2.cfg file on the controller&#8217;s SD card, and firmware updates arrive the same way \u2014 the <a href=\"\/download\/spilamp2usermanual.pdf\">user manual<\/a> walks through both.<\/p>\n<h2>Which controllers work with this SPI signal splitter?<\/h2>\n<p>LEC 3 and SPI MATRIX only.
