It also supports RDM (Remote Device Management), which adds two-way communication so you can change the DMX start address or adjust settings remotely.\u003c\/p\u003e\u003ch2\u003eRJ45 in and out\u003c\/h2\u003e\u003cp\u003eDedicated RJ45 input and output ports carry the DMX signal over standard network cable with plug-in connections, so installs are quicker and tidier. Daisy-chain several decoders on one DMX line. With more than 32 decoders on a line, add a signal amplifier, and fit a terminal resistor at the end of the line for a stable signal.\u003c\/p\u003e\u003ch2\u003eSet up on the unit\u003c\/h2\u003e\u003cp\u003eA digital display and buttons let you set the DMX start address on the decoder itself. It uses four DMX addresses, with 1, 2 or 4 channel output modes to suit the fittings.\u003c\/p\u003e\u003ch2\u003eOutput\u003c\/h2\u003e\u003cp\u003eThe decoder runs on 12-48V DC. At 12V and 24V each channel gives up to 8A; at 36V and 48V each gives up to 6A, for up to 1152w in total at 48V. Use it only with constant voltage LED products and a suitable constant voltage power supply, never with constant current fittings.\u003c\/p\u003e\u003ch2\u003eSmooth, flicker-free dimming\u003c\/h2\u003e\u003cp\u003eChoose a PWM frequency from 250Hz to 32kHz; higher settings cut visible flicker for cameras, shops, showrooms and exhibitions. 8-bit or 16-bit dimming gives 256 or 65,536 levels for smoother fades, with logarithmic or linear dimming curves.\u003c\/p\u003e\u003ch2\u003eSelf-test and protection\u003c\/h2\u003e\u003cp\u003eIf the DMX signal is lost, a self-test function starts, with five modes (L-1 to L-5) for commissioning and fault-finding. Overheat, overload, short-circuit and reverse-polarity protection are built in, with automatic recovery. The iron case has a built-in heat sink.\u003c\/p\u003e\u003ch2\u003eWhere to fit it\u003c\/h2\u003e\u003cp\u003eThe case is 175 x 46 x 32mm, so it fits in control cabinets and equipment enclosures. It is rated IP20 for dry indoor locations and works from -30°C to 55°C.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eType: 4 channel DMX512 and RDM decoder, constant voltage\u003c\/li\u003e\n\u003cli\u003eDMX ports: RJ45 in and out\u003c\/li\u003e\n\u003cli\u003eInput: 12-48V DC\u003c\/li\u003e\n\u003cli\u003eOutput: 4 channels, 12-48V DC\u003c\/li\u003e\n\u003cli\u003eOutput current: 8A per channel at 12-24V, 6A per channel at 36-48V\u003c\/li\u003e\n\u003cli\u003eMaximum output: 1152w at 48V\u003c\/li\u003e\n\u003cli\u003eDMX addresses: 4, with 1, 2 or 4 channel modes\u003c\/li\u003e\n\u003cli\u003ePWM frequency: 250Hz to 32kHz\u003c\/li\u003e\n\u003cli\u003eDimming: 8-bit or 16-bit, logarithmic or linear curve\u003c\/li\u003e\n\u003cli\u003eSelf-test: 5 modes\u003c\/li\u003e\n\u003cli\u003eProtection: overheat, overload, short-circuit, reverse polarity\u003c\/li\u003e\n\u003cli\u003eCase: iron, black, 175 x 46 x 32mm\u003c\/li\u003e\n\u003cli\u003eWorking temperature: -30°C to 55°C\u003c\/li\u003e\n\u003cli\u003eIP rating: IP20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LED Supplier","offers":[{"title":"Default Title","offer_id":57688463212917,"sku":"D4-E","price":38.09,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/9772\/5645\/files\/D4-E.png?v=1792702404","url":"https:\/\/ledsupplier.co.uk\/products\/4-channel-dmx512-rdm-led-decoder-rj45-constant-voltage-12-48v","provider":"LED Supplier UK","version":"1.0","type":"link"}
