I assembled the K8074 kit to control the VM151 RGB led controller.
The software is correctly installed, com port 5 is automatically assigned, and accepted by
the program after pressing the connect button.
LED4 ( ON) is on.
LED3 (RX/TX) lights shortly when TEST buttun is pressed.
LED1&2 (USB) are pulsing rithmically to each other.
Nothing changes to the LED’s when making any changes in the control program.
The VM151 does not repond to any signal. (I guess there is no signal?)
The VM151 is functioning perfectly with the VM130T remote.
What could be wrong?
