RJ-45/DB-9 splitter cable pinout
The MediaPort 7000 series and the ChannelPort modules ship with one integrated RJ-45 to DB-9
(Female) splitter cable. RS-422 connections for both channels A and B on the MediaPort 7000 series are
on one RJ-45 port. This cable splits the two sets of signals out to two DB-9 connectors.
Use the Harmonic RJ45/DB-9 splitter cable to interface with controllers (or cables) using standard
SMPTE/EBU ES bus wiring connections. This adapter converts the RJ45 connections on the back of the
MediaPorts to standard SMPTE/EBU ES Bus.
