DVC GOLD HE10 Pinout and description accuracy

[Jean-Philippe@Fort]

Good day!

Here at The Fort, we have 2 DVC Gold units. I need to connect an emergency full-on lighting through the HE10 connector, linked to our security / evac system.

Available docs at the moment indicates 2 as GND, and 9, 8, 7, 6 as Ports 1, 2, 3, 4

Also, the present docs only represent 8 ports, like here :
https://www.daslight.com/manuals/#/en/d ... tact-ports

Which refers to Farnell 10-pins connectors:

The DVC Gold has a 20-pins connector, known to me as HE10xx20 like this :

But the pinout seems to be quite different:

In looking to close a dry contact, I was going nowhere between pins 2 and 9, 2 and 8 etc. Myself being of sufficient "mass", hitting Pin 1, 2, 3 etc with a non-insulated object did launch 1, 2, 3 ; digging further I found Pins 19 and 20 to be both grounded, and that jumping 20 and 1 launches 1, 20 and 2 gets 2 etc etc, 19 works the same. And we have 16 ports!


Am I crazy ? Is there a doc somewhere about this that I didn't find ? I really appreciate the logic of Pin 1 being Port 1 and so on btw, it is great.

Am I missing something ?

Thanks in advance.
