Motorpot remote controlMotor pots such as e.g. The ALPS RK27112MC can be remotely controlled with this module. Nearly all audio handset switches for Philips, Grundig, Marantz (RC5) or even a universal remote control can be used to control the function. For Logitech Harmonie, for example, the code for Marantz CD 63 of our CN handset.

After connecting the supplied infrared receiver, a 5V supply voltage is required. The motor of the motorpot is connected to PIN 4 and 6. Switching on reduces the volume for a moment.
The left port can control relays for up to 4 sources. The mute button on a remote control switches off all source relays, and when pressed again, re-activates the last known relay.
A relay for e.g. "Stand By" can be controlled with pin 15. With push buttons to ground / GND can also be controlled manually without remote control.
· Pin 3/4: Motorpot right / left-run
· Pin 13/14: Source selection up / down
With "reverse logic", the switching signal for the relays can be inverted during operation. Depending on the requirements in a pre-amplifier or integrated amplifier or relay cards, the module can provide the necessary signal without any changes to the existing circuit. Pin 16 is to connect to 5 volt for inverting.
Relays are always controlled via a shield and can not be connected directly to a microcontroller because of their current consumption. Such a shield consists of a transistor or opto-controller, which switches the coil voltage for the relay. Depending on the wiring, this shild requires a 5V "signal high" or a 0V (GND) "signal low" from the microcontroller.
