ASD interface

I was hoping to do section control on a Muller Spraylight which has an rs232 ASD interface. I found an existing interface from CoffeeTrac ;

Does any one know if this will still work with the latest versions of AOG, or have any other suggestions.


Rauch controller was made by Mueller elektronik in germany.

So i think it is the same comunication protocol. it is RS232.

I think you need only three wires TX, RX, GND

But you need to connect in this way

TX of mueller = > RX of MAX3232
RX of mueller => TX of MAX3232
GND of mueller => GND on MAX3232


Thankyou for the pinout diagram that is very helpful. Have you done this yourself? Does the Coffeetrac esp32 program still talk to the AOG, it looks to me as though the sentences for section control sent to the ESP32 may have changed ?

I find the schematic on google.

The ESP32 is connected to pc by usb connection.

In the version 5, the comunication is managed by AGIO.

I do not know how AGIO works and if there are some difference with old software version.

For the cable, you can buy a DB9 rs232 serial null modem cable

Do you have cable connection diagram for amados plus?

There is an ASD adapter cable harness. (Code NL394)


yes this cabel you have its internal connections
