To use the analog remote control, connect a contact closure switch e.g., a light barrier or a push button.

Generate a switch that sends between +5 and +15 volts to pin 1 for the console to react to analog input number 1.

There are two ways to generate a switch:

1. Take the +5V voltage from pin 21-22.\
   -or-
2. Take an external voltage (+5V up to +15V), connect the ground of the external voltage source to the common ground pin of the grandMA2 console or MA onPC command wing.

Then connect the switch to one input pin 1-16 with a potential free contact (switcher, buzzer, motion detector, or any other switching device) in between.

To configure the remote see [Remote Controlling the System - Remote Input](/grandma2/key_remote_control_input/).

**Pin layout for grandMA2 consoles:**  \
The grandMA2 consoles have a 25 pin D-sub, enabling 16 remote inputs:\
Pin 1-16 = input\
Pin 21-22 = + 5V\
Pin 25 = common ground

**Pin layout for MA onPC command wings:**\
The MA onPC command wing has a 15 pin D-sub, enabling 12 remote inputs:\
Pin 1-6 = input channels 1,3,5,7,9,11\
Pin 9-14 = input channels 2,4,6,8,10,12\
Pin 7 = + 5V\
Pin 8 = common ground\
Pin 15 = not used

- Connect a D-sub plug to the DC remote control connector on the rear panel.

The analog remote control is connected to the DC remote control.
