Applying Power to the Transmitters
Each DTV-TX-03-US Transmitter receives 12 VDC power via the 12VDC POWER
connector on the rear panel (FIG. 4).
Note
: This connector is intended to be used only with the provided power supply.
Connecting TV Sources to the Transmitter
DTV-TX03-US Transmitters receive QAM/ATSC digital TV broadcasts, and connect to a
cable outlet via the TUNER IN (RCA) connector. In order to use the TUNER IN connector
with coax cable, you must first install the included RCA-to-Coax adapter (FIG. 5):
Connecting a Digital Cable TV Source to DTV-TX03-US Transmitters
To connect from cable to the DTV-TX03-US, use coax cable with an F-type connector
(FIG. 6):
Recommended Signal Levels
AMX TDS Transmitters require good quality input signals. The recommended signal levels
are specified below.
ATSC:
•
Signal level: > 45 dB
µ
V and < 70 dB
µ
V
•
Signal to noise ratio (SNR): > 26dB
•
Bit Error Rate (BER): < 2E-04
QAM:
•
Signal to noise ratio (SNR): > 7 - 9 dB
•
Bit error rate (BER): < 2E-04
Connecting the Transmitters to the Network
Use the ETHERNET 10/100 Port on the front panel of the DTV-TX-03-US Transmitter to
connect each Transmitter to the network, via Cat5/5e/6 UTP network cable (FIG. 7).
•
DTV-TX03-US Transmitters require a Layer 3 Gigabit Switch with multicast support,
IGMP Querier/Snooping and PIM.
•
Network Configuration for the Transmitters is done via the TDS Configuration
Manager (see the
Transmitter Setup - Network Settings
section of the
AMX TDS
Television Delivery System (ClearQAM / ATSC) Operation Reference Guide
for
information).
•
By default, DTV-TX03-US Transmitters are set to
DHCP
.
Setting the Transmitter’s IP Address via the RS232 Port
In most cases, all setup and configuration for both Transmitters and Receivers is done via
the Digital TV Configuration Manager. However, the Transmitter’s IP Address can also be
specified via serial command, using the RS232 port on the rear panel (see FIG. 1).
In order to configure the network settings via the RS232 port, the Transmitter must be
placed in command mode. To place the Transmitter in command mode, pres “Enter” while
the unit is booting up.
To reboot, re-cycle power by disconnecting and re-connecting the 12VDC POWER
connector on the rear panel.
Note
: The default baud rate is
115200
.
Use the
setip lan
serial command to configure the network settings:
Note
: All DTV Transmitters and Receivers must have an assigned
IP
Address
,
Network
Mask
, and
Gateway
Address
in order for the DTV system to work correctly. This applies to
units that utilize DHCP and to units that have been assigned Static IP addresses. If you are
using DHCP, verify that these address assignments are provided by the DHCP Server.
Configuring DTV-TX03-US Transmitters
DTV Transmitters are configured via the Digital TV Configuration Manager (see below).
Digital TV Configuration Manager
The DTV-MA01 TDS Management Appliance features a built-in web console called the
Digital TV Configuration Manager
. The Digital TV Configuration Manager allows you to
configure the Receiver and all Transmitters in the TDS solution via a web browser on any
PC that has access to the DTV-MA01 in the TDS system.
These instructions assume that the TDS System has been installed, and that the
DTV-MA01 and a PC is connected to the LAN.
Accessing the Digital TV Configuration Manager
1.
On any PC that has access to the LAN to which the DTV-MA01 is connected, open a
web browser and enter the following default URL to access the TDS Configuration
Pages (on the DTV-MA01):
http://
<
IP Address assigned to the DTV-MA01
>
:8080/TDS/web/TxNetworkPage.xml
2.
Press enter to be prompted for the default
User Name
and
Password
for the DTV-
MA01:
•
Default
User Name
: “
amxdtv
” (case-sensitive)
•
Default
Password
: “
admin
”
(case-sensitive)
Note
: The User Name and Password can be changed via options in the System
Setup page (in the Digital TV Configuration Manager). See the AMX TDS Operation
Reference Guide for details.
3.
Press
OK
to proceed to the Digital TV Configuration Manager. The initial view is of
the
Transmitter Setup
page (FIG. 8). .
The command buttons along the top of the page provide access to the main areas of the
Digital TV Configuration Manager:
•
Tx Setup
- Click to configure DTV Transmitters
•
Rx Setup
- Click to configure DTV Receivers
•
External AV
- Click to add and configure external AV devices to be included in the
TDS system
•
