Serial control connections for a MediaPort 7000 and a
ChannelPort
The MediaPort 7000 and the ChannelPort modules include an RJ-45 port for RS-422 serial control
connections with an automation system.
NOTE:
Because manufacturer specifications for cables, connectors and adapters
can change, always consult with your control system vendor first for the most current
information on interface equipment and peripherals.
NOTE:
Depending on the MediaPort, there can be between one and six serial control
ports, each of which controls an independent DVB/ASI output. You are not required to use
all available ports.
On both the MediaPort 7000 and the ChannelPort, the left-most RJ-45 connector is wired for two
channels (Ch 0 and Ch 1). Harmonic supplies an RJ-45/ DB-9 splitter cable, which provides the Channel
0 on one DB-9 and the Channel 1 signals on the other.
Pinout assignments for the RS-422 port on the MediaPort 7000 and the ChannelPort modules is shown in
the following diagram. The connector type is RJ-45 (female)
