Installation Guide
DTV-TX01-DVB-T
Digital Video Broadcasting, Terrestrial, dual tuner transmitter
Overview
The DTV-TX01-DVB-T Transmitter is one component of an AMX TDS Television Delivery
System. The AMX TDS system delivers digital TV and video signals across a privately
provided IP network infrastructure. The DTV-TX01-DVB-T Transmitter (
FG1410-01
) supports
DVB-T (terrestrial)
signals, and features RF 1/2 OUT output connectors to allow multiple
streams for maximum channel coverage (FIG. 1).
Product Specifications
AMX TDS System Description
The AMX TDS system can be deployed in any installation where digital A/V broadcast over
IP is desired, and delivers Digital TV and other encoded A/V signals to a number of TV sets,
or desktop PC's.
System Components
The AMX TDS system consists of several components, including a DTV-MA01 TDS
Management Appliance, Receiver (and IR Remote Controller), and Transmitter modules.
There are two Transmitter units available, to accommodate Terrestrial and Satellite digital TV
broadcasts. See the
AMX TDS Operation/Reference Guide
for details.
Network Considerations
Because of the high bandwidth associated with A/V distribution, the TDS system is typically
managed via a separate IT infrastructure. However, content may be streamed over the main
network if desired. Consult your IT representative to determine the proper network
configuration for the TDS system.
The AMX TDS system transmits audio/video using IP multicast. In order for this to work
satisfactorily, it is vital that the network switches are multicast-enabled in order to prevent
unwanted flooding of traffic on the network.
•
Within the context of AMX TDS documentation. the term “Multicast-enabled” means
that all network switches carry out IGMP snooping, and one switch must function as
the IGMP querier.
•
AMX Digital TV supports version 2 of IGMP.
Front Panel Components
ETHERNET 10/100 Port
The ETHERNET 10/100 (RJ45) port on the front panel provides 10/100 BaseT network
connectivity.
Network Port Pinouts and Signals
The following table lists the pinouts, signals, and pairing for the NETWORK port.
Consult the Network Administrator for correct cabling from the DTV-TX Transmitter onto the
network. For remote connectivity, the Firewall may have to be configured to open port
2008
for remote connectivity over UDP. Ports
5000
and
5001
are required for the Transmitters as
well as any ports used for the TDS Multicast stream.Ports
5002
and
5003
are fixed as the
multicast stream output ports.
Ethernet LEDs
Status LEDs
There are three LEDs on the front panel to indicate various types of device status:
•
Power Status
(
yellow
): Lights to indicate that the Transmitter is receiving power and is
functional. If the LED fails to light, check your 12VDC Power connection.
•
Network Connectivity Status
(
green
): Lights to indicate that the Transmitter is
connected to the network.
•
Streaming Status
(
yellow
): Flashes if only one tuner is streaming. Steady on if both
tuners are streaming.
Default IP Address
By default, DTV Transmitters are set to
DHCP
. See the
Setting the Transmitter’s IP Address
via the CONSOLE Port
section (below).
