I have been trying to work out how I can get the Alarm port of an SBP connected to teh Digital Input on a Cerbo GX and haven't been able to work it out.
Has anyone got any guidance on this?

Cerbo Digital Input from SBP
What have you tried so far and at what point do you have the problem? What do you want to achieve with that?

@Matthias Lange - DE, When the SBP switches off, due to Low or High Voltage, I want it to trigger an alert on the Cerbo. I know that the Cerbo has a Positive or Data side and a Ground. What I can't work out is how to get the Alarm PIN wired to the Cerbo.
Is it possible to take a positive feed from say the battery to the positive side of the Cerbo and the Negative on the Alarm pin of the SBP to the ground on the Cerbo. My assumption is that the SBP is acting like a switch and will break the circuit, causing a loss of signal to the Cerbo.
Many Thanks
"If a logical low input (0V) should be considered a positive condition, set Inverted alarm logic to on."
Also have in mind that the SBP gives you the alarm 12sec after the low voltage is reached and it will turn off after 90 sec.
Maybe it is easier to just connect the load output of the SBP to the input of the cerbo.
