b) outputs: pin 2 to PWM whites, pin 2 to PWM for blues and pin 6 as ground
c) I use two Mean Well CLG-150 power supplies and power supplies ground is connected to pin6 ground
Should I use pull-up resistors 10k between power supplies +20V and PWM outputs? When I measure PWM without connecting to CAT 4101 driver I measure 5V and when L1/L2 is set to 10V, but when I connect PWM output pins 2,3 to CAT4101 drivers, PWM drops to 0V. Any advice?
Due to the fact, that the LEDControl can only switch between high resistance and zero, you need pull-ups at the outputs. The Arduino uses internal pull-ups. But be careful, your CAT4101 only accepts up to 6V at the PWM-Pin. So you have to connect the resistors to the 5V and not to the 20V.
