NOTE: Do not exceed the supply voltage at the beginning of your data line/at your first LED
product.
2. Re-supply voltage at some point (where the voltage drop measured is significant)
before the faulty LEDs are visible (e.g. in the middle of the line) or at the end of the
line.
NOTE: Note that resupplying power must be done from the same power supply or
if another power supply is being used, all grounds of of all power supplies must be
connected in order to balance the ground potential.
Tip: Do not use excessive wire gauges to transfer data from the DiGidot C4 to the LED-
products, this will only increase the risk of failures. Typically we recommend to use wire
gauges for the data signal of 0.3-0.5 mm2 (20-22 AWG).
