Web Browser User Interface
In addition to the front panel, the user may control and monitor the unit using the rear-panel Ethernet connection. Before using the
Ethernet connection, the appropriate IP address, netmask, and gateway must be selected via the front-panel interface. There are two
basic methods of using the Ethernet connection – with a directly connected PC or with a LAN connection.
Locally connected PC –
Connect the DTV744 Ethernet connection to the Ethernet network connector on the PC using a crossover RJ-45 cable (8 pins).
Set the DTV744 IP Setup as follows: IP Address: 172.016.100.020 Netmask: 255.255.000.000
Gateway: 000.000.000.000
Set the PC IP address as follows:
Connect to the DTV742 using the web browser instructions below.
LAN Connection –
Connect the DTV742 Ethernet connection to the LAN using a normal RJ-45 cable (8 pins). Set the DTV744 IP Address, Netmask,
and Gateway as directed by your network administrator. Use any PC on the LAN to connect to the DTV744 using the web browser
instructions below.
1
IP Address: 172.016.100.001 Subnet Mask: 255.255.000.000

To change the PC IP address, go to the Settings, Control Panel and double click on the Network icon. Select Configuration, TCP/IP protocol, and click on the
Properties box. Click on Specify IP Address and set the IP Address and Subnet Mask as indicated. Click OK to restart the PC with the new values.

Using the Web Browser –
Using the web browser of your choice, set the Address to http://nnn.nnn.nnn.nnn where nnn.nnn.nnn.nnn is the IP address of
the unit to be controlled. Each unit on the network must have a unique address. You should see the pages below when connected
to the unit. (Be sure that your screen resolution is set to at least 1024x768 so that all items are visible. Lower resolutions will
prevent you from viewing all the available tabs.) You may select which page to view by clicking on the Control and Status, Stream
Information, Unit Configuration, Config In, Config Out (1, 2, 3, or 4), or Q&A/Help tabs.
The Control and Status tab (shown below) allows you to select the channel number for the RF input. The status section provides
signal status.

The Stream Information tab below shows input and output status. No user inputs are located on this screen.
The Unit Configuration tab below shows the current configuration in use and allows storage and loading of 10 separate
configurations. A configuration is the set of all user settable items (inputs and outputs) in the unit.

Elevated Operating Ambient
If equipment is installed in a closed or multi-unit rack assembly, the operating ambient of the rack may be greater than the room ambient. Therefore, considerations
should be given to the TMRA, or Temperature inside the Mounting Rack, and not just inside the room.
Reduced Air Flow
Installation of the equipment in a rack should be such that the amount of airflow required for safe operation of the equipment is not compromised.
Mechanical Loading
Mounting of equipment in a rack should be such that a hazardous condition is not achieved due to uneven loading. This unit is not very heavy, but total rack loading
should be considered.

Circuit Overloading
Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of circuits could have on over-current protection
and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
Reliable Earthing
Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connection to the
Branch (use of power strips).
Desktop Installation
To set up the DTV735 in a desktop environment, place it on a flat surface where it will not be subject to being hit or pushed, and will not have anything spilled or
dropped on it. Also, the cables connected to the unit should be routed so they are not hit or pulled, which might cause damage to the connectors or to the unit itself.
Additionally, there should be sufficient flow of cool air so the unit stays within its operating parameters.
Rack Installation
When installed in an equipment rack, it is best that the DTV735 be supported by angle brackets or cross supports. These should be screwed or bolted securely to the
equipment rack, and be capable of supporting the unit and its connecting cables. Do NOT install the unit if you have doubts about the unit being safely supported. There
are also 4 holes in the front brackets, which are designed to accept screws for further anchoring. It is also essential that these brackets be used so the unit cannot be
moved forward and fall from the rack. It is always best to install the angle brackets or cross-members before setting the unit in place. Then, prior to installing cables,
put anchored screws or bolts-and-nuts into place on the front brackets. Failure to do this can lead to pushing the unit out the front of the rack in later steps.
