DMP TV Control Connections
Cisco StadiumVision Director controls what is displayed on the TVs and also
controls the TV settings (e.g., turning the TV on or off, setting volume level, etc.).
Cisco StadiumVision Director sends commands over the IP network to the DMP.
The DMP then sends those commands to the TV via the RS-232 port of the DMP.
There are two primary ways to transmit those commands to the TV: a direct RS-232
cable connection or an Infrared connection. The infrared option requires the addition
of an RS-232-to-Infrared (IR) adapter to make the command signal conversion from
RS-232 to IR.

Note: As another alternative for TVs that do not provide an RS-232 port, certain
commands (such as volume and mute) can be issued directly to the DMP using the
DMP Sigma commands.

Using a Direct RS-232 Connection
Making a direct RS-232 connection between the TV’s RS-232 port and the DMP’s
RS-232 port provides the simplest and most reliable way to remotely control the TV.
RS-232 is typically provided on commercial-grade displays that are recommended
for the Cisco StadiumVision solution.

The DMP 4310G uses a 3.5 mm audio jack for the RS-232 connection. The DMP
has three 3.5 mm audio jacks side by side, so be sure to connect the correct one.
The DMP 4310G ships with a 3.5 mm to 9-pin female DCE cable that connects to
this port. The default RS232 configuration is 9600/8/N/1 with no flow control, which
also matches the default settings of most TVs.

Guidelines for RS-232 Cables
Careful consideration must be made before buying RS-232 cables for connecting
the DMP to the TV. Things to note are the gender and type of connector on the TV
and wiring configuration for the connector. The TV might have either a DB-9 or RJ-
45 connector and be wired as a straight or null modem cable (for example, TX and
RX pins are swapped). Check with the manufacturer of the TVs manual for this
information before purchasing cables.
