The short answer is – I don’t know.
This looks more like the U.S. equivalent of a commercial grade LiftMaster opener rather than a residential garage opener. We’ve had a few users experiment with these types (see Medium Duty Logic MJ5011U not working) but so far no confirmed success. I think the wireline protocol used by the commercial grade products is different from those used by the residential line, despite using the same “Security+2.0” branding.
You are likely right that OPN, CLS, STP, COM are dry-contact inputs for the various directional controls. The GDO blaQ uses a serial data method of communication, so my best guess, if it were to work at all, would be via the D1 terminal and COM. But again, I’ve never tested with this model/brand so your guess is as good as mine.
