I am using a ECG P-12 for 2811 strips. The 12 outputs are split between two separate 350W power supplies. One of the power supplies will control six outputs connected to six separate strips connected to my house. The second power supply will control 4 outlets controlling 4 cut up vertical 2811 strips on a fence. These 4 strips will be at least 40 feet from the Power supply and controller. I know I'll likely need to inject power to overcome voltage loss, however, how do I ensure the data signal does not degrade as it travels the 40 feet from the controller to each of the four strips? Will I need to add null pixels? How many would be needed?
