Installation Guide

DTV-TX03-US 

Digital TV Transmitter QAM/ATSC

Overview

The DTV-TX03-US Digital TV Transmitter (

FG1410-03

) 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-TX03-US receives incoming ClearQAM or ATSC digital TV signals, and sends the 
digital TV content to the DTV Receiver located at the display (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. 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

Note

: The USB Port on the front panel is not used at this time.

Status LEDs

The two status LEDs are located on the front panel, directly beneath the AMX logo

Rear Panel Components

TUNER IN

The TUNER IN (RCA) connector accepts incoming QAM/ATSC TV signals via coax cable 
(FIG. 2). 

In order to use the TUNER IN (RCA) connector with coax cable, you must first install the 
included Coax-to-RCA adapter (see FIG. 5).

10/100 Port

The 10/100 (RJ45) port on the rear 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.

Default IP Address

By default, DTV Transmitters are set to 

DHCP

.

Network Switch Requirements

DTV-TX03-US Transmitters require a Layer 3 Gigabit Switch with multicast support, IGMP 
Querier/Snooping and PIM.

RS-232 Port 

The RS-232 Port on the rear panel provides a serial interface that provides basic diagnostics 
and the ability to change the IP address, via a standard DB9 connector.

Use a standard DB9 programming cable such as the CC-232 (FG10-752-04, not 

included) to connect to a PC for Terminal control. 

Supported terminal commands are listed in the 

AMX TDS Operation/Reference Guide

.
