The DFS4000 LED unit comprises a metal base, a PCB assembly and screws to fasten the two parts together. The metal base is manufactured from anodised aluminium with a black finish. The PCB assembly comprises decoding circuitry to recover the combined power and data information, LED drive circutry and the LEDs. The LEDs are driven with true constant current not PWM. This gives excellent visibility even when viewed with a camera. The system provides full 8 bit independent control of the red, green and blue LEDS. There are six RGB LEDs which give a total output of approximately 4500mCD.
Up to 100 LED units can be attached to a common two conductor standard speaker cable. The cable cross section is just 6mm x 3mm. Connecting the LED unit to the cable is very simply achieved by just placing the cable into the aluminium base fitting the PCB assembly on top and then screwing this down with two small M2.5 screws which are provided. The PCB assembly incorporates cable piercing pins which cut the cables insulation to automatically form a connection.
Up to 100 LED units can be placed at any spacing along the cable up to a maximum length of 50M.
Once the units are fitted in place they are each given a unique address using the hand programmer described below. This operates over a short range infra red link.
