Cerbo Gx digital input internal wiring

Dear All,

I wish to trigger the GX dig input with an opto.

Should I connect the opto out gnd to BOTH the GX power gnd AND the dig input lower pin (opto out signal to dig input higher pin + some resistor if needed), or the dig in lower is anyway connected to the Gx pwr gnd internally?

(As the whole high/low is programable concerning the dig inputs, naturally the dig in lower or higher is interchangable).


Thx,

Tibor
