Telex ADAM Zeus RJ-45 Wiring Standard
Keypanel RJ-45 to DB-9M Adapter Schematic

The Telex Matrix-Type intercom Products use either a DB-9 or an RJ-12 connector.
Since both of these connectors are not as usable as an RJ-45, due to its wide acceptance in the data networking industry, it was deamned necessary to adapt to this more common connector. The other analog wiring scheme used by Clear-Com Intercom Systems "Matrix-3" was adapted as the model to use in the ADAM type systems due to the desired interchangeabliity of existing adapters and accessories.
