Hardware questions

Hi there,

I have an oven with the Micronova Mod0047 Evo control.

This has a D-Sub connector to the outside, 18V / 5V Serial / GND (source k3a.me)
And the 4-pin serial interface (CN9) is soldered onto the circuit board.

Does jamend know whether I can also pick up the signals with your circuit board layout at the D-Sub output?

Or should the internal connection be used?

Regards
Gerald

Hello
According to k3a.me here is the pinout of the DB9 connector. However, the fixed 5V is missing on its schematic, and it is necessary to have it. I would recommend you to use the internal connector (less pins, so much less possible errors), but you can try to find the fixed 5V on the DB9 connector (it should be easy to find, since we know the GND pin).

Hi there,

I once measured the 9-pin D-SUB socket and here is the pin assignment.
Maybe someone still needs them ;-)

I use an ITC Layma with a Micronova mod0047 EVO control-board.

Pin 7 & 6   | GND
Pin 1       | 5V
Pin 3       | 20V

Hello, thank you for your schematics! I will soon create a markdown page with all the information that may be useful, like this diagram.
