We have a fountain installation consisting of four rings and one v structure with Pem e2100 dmx controllable lights and dmx relay controllers. There is a main controller supplying dmx512 to each ring and V structures using a dmx splitter with 5 output and 1 input.In each ring 1 relay controller (consuming 3 channels ) and 16 rgb lights (consuming 3×16=48 channels ) is connected in daisy chain with last light out terminated using 120 ohm resistor . This is same done for other rings and V structures.
The problem is when I started sending dmx signals after addressing all; the relay controllers are responding but the lights are like in a black out stage with no response.
The dmx master controller is dac quad from gilderfluke and Co, the relay controllers are pb dmx/24 relay controllers from gilder fluke,the lights are Pem e2100 rgb led lights.The splitter is opto 125 from gilderfluke,the software is Pc Mac from gilderfluke and Co.
