Wiring the DB25/RJ45 adapter
This chapter provides instructions for wiring the provided DB25‐to‐dual‐RJ45 adapter for Dolby Digital
cinema playback systems that output 16‐channel audio via a DB25 connecter.
Instructions are provided for the Dolby DSS200 (equipped with a CAT862 media block (MB)), and the
Dolby DCP‑2000 and Dolby DCP‑2K4 (equipped with a Dolphin MB).
Note: Dolby DSS playback systems provide two MB options, the CAT862 and CAT745. The
CAT745 option outputs 16‐channel audio via RJ45 Ethernet connections and does not
require an adapter.
Warning: To avoid exposure to dangerous voltages and to avoid damage to the unit, do
not connect the rear‐panel RJ45 ports to telephone circuits.
