Texecom Speech Dialler To Texecom Panel

[Ben6279]

I'm just installing a Texecom Veritas Excel panel along with the Texecom speech dialer. Reading the installation manuals of the two, neither really cover connecting devices of their own brand together, more of if connecting different brands to each other.
The choice I have I hope someone can advise me on is on the panel it has a dedicated "Communicator Interface" which the panel manual states to supply the communicators power from using the unfused 12v connection.
The Speech dialers manual states "12v & 0v must be connected to the 12v aux psu of the control panel" which this is obviously fused.
Which should I use?

Also the Speech dialler, the TNV connections requires an earth. Is this mains earth, earth as in 0v on the panel & where should I supply this earth from?

Thanks.

Use the aux dc.
Mains Earth.

Page 16 shows how to connect.

Use the aux dc.
Mains Earth.

Page 16 shows how to connect.

The wiring example for a communicator it shows on page 16 is the bank of terminals at the top of the board marked "Communicator Interface" where as the aux dc is along the bottom edge of the board???

Use the Aux DC and the communicator bank for signals.

As I said.
