3 Installing an HDX-1100 Transmitter The HDX-1100 is built in an ARINC compliant 3/8 ATR housing, and was designed primarily for aircraft operation. It is also suitable for general mobile applications, including terrestrial vehicles. The transmitter and its remote control panel (RCU) have been tested and certified to be compliant with RTCA DO-160F, as recognized by the FAA and other global agencies that regulate aircraft operation and safety.

ENCODER WEB BROWSER MANAGEMENT (Ethernet) DC CIRCUIT BREAKER RF OUTPUT HDX-1100 REAR PANEL The following electrical connections must be made to place the HDX-1100 in service.
NOTE: There is a 10 AMP DC circuit breaker on front panel of HDX-1100. If the power to this breaker is fed from another circuit breaker in the aircraft, the HDX-1100 breaker should be left in the on position. To operate the breaker: push in = ON, pull out = OFF, a manual reset is required after the breaker trips.
HDX-1100 installed in optional 3/8 ATR mounting tray with spacers The optional 9000372 3/8 ATR mount includes a set of spacers that may be installed if clearance is not sufficient to allow the clamps to disengage. The spacers would not be needed if the mounting plate is attached to a shelf within the airframe, as shown below.
4 Controlling the HDX-1100 with the Touch Panel The touch panel screen on the front of the unit lets you perform routine setup and maintenance functions and control the HDX-1100 directly as described in the following sections. NOTE: To use the HDX-1100 front panel controls, the RCU panel must be turned off or disconnected prior to turning the HDX-1100 on. 4.1 Selecting a Preset or a Channel The HDX-1100 recalls the most recently saved preset and channel when it is powered up.
5 Setting the HDX-1100 with the Aircraft Remote Panel You can install the Aircraft remote control unit (RCU) up to 50 feet from the HDX-1100 using a 3-wire serial interconnection and a power source. The following figure shows the RCU. Remote Control Unit – Part Number 907621-6 When the remote panel and HDX-1100 are powered up at the same time, the remote takes priority and the HDX-1100 local touch screen will not have any menu items shown, and will appear as the in the photo below.
Function Push Buttons Name RF ON/OFF BRIGHTNESS LED Displays Rotary Switches LCD Display Description Switches the transmitter RF output between standby (STBY) and transmit (XMIT) conditions. In STBY, the RF output is zero. Sets the display brightness to high (H), low (L), or automatic (A; light sensing). STBY Indicates the HDX-1100 is in standby mode (No RF output; unit is powered but not transmitting). XMIT Indicates the HDX-1100 is in transmit mode.
6 Configuring the internal HDX-1100 with a PC The HDX-1100 is based on the ultra-portable Vislink HDT-1000 transmitter that has been integrated with additional components and subsystems needed to provide a high performance airborne or mobile transmission system. Presets numbers 6 through 9 of HDT-1000 module are programmed with factory defaults representing typical video settings that may be used as they are, or modified to suit your specific operating requirements.
prevent unauthorized access. The new user name and password should be recorded and stored in a safe place. 6.1 MAIN SCREEN: After the login procedure is complete, the browser will open to the MAIN SCREEN, providing a view of operating conditions for the currently active pre-set. A drop down menu on the pre-set line allows you to change to any available pre-set and review the parameters for each pre-set. Changes to pre-sets CANNOT be made from this screen of the browser.
To view, click on ―Status‖ in the bar at the top of the screen, and a drop down section will appear. Select which of the status items you wish to review and all of the viewable parameters will be summarized in a column on the left side of the screen.

These should be changed to match your speci fic network requirements. Changes are accomplished by entering the new values in the dialog boxes then clicking on the submit button.
6.4 CONFIGURING PRESETS For maximum flexibility, a complete set of parameters must be defined for each preset that is programmed into the HDX -1100. To begin the process, select Preset from the drop-down menu in the bar at the top of the display, and the screen shown below will appear. PRESET SCREEN The Preset Text box accepts user input to identify each preset is. Text is entered by the user for each preset, and saved with the Submit button.
Submit button when you are satisfied with the result. Next, click on the Modulation button in the menu bar at the top of the screen. M O D U L AT I O N S E T U P S C R E E N Modulation setup determines the bit rate that the transmitter can send to the receiving station for each preset. Lower bit rates will work better in situations where extreme fades, interference, or multipath are present. Higher bit rates are not as robust; however, they may be required for highest quality HD transmission .

6 . 6 C H AN N E L S E T U P Normally, a customer specified channel plan is set up at the factory when the HDX-1100 is built, however, additional channels may be added at any time, or existing channels may be redefined if necessary. These changes can only be made by qualified technical service personnel. CHANNEL PLAN SETUP SCREEN For each channel to be added or set up, enter the correct frequency information in the dialog box on the right-hand side of the screen corresponding to the desired channel number.
6.7 Recalling a Preset Configuration from a PC 1. Select Preset from the Radio drop down menu. 2. Select the preset number and click Load. The relevant parameters will be populated under Video and Radio. 3. Select ―save‖ to change to the active preset. Note The Encryption code will not display. Click Logout to finish setting up the HDX-1100 Once this procedure has been completed, the pre-sets that were established may be recalled using the aircraft remote panel.
MAIN SCREEN OPERATION When operating the HDX-1100 transmitter in local mode (touch screen active), the main screen will be displayed first. The current preset and channel selections are controlled by touching the up and down buttons below the respective sections of the display. For example, to move to a lower channel, touch the down arrow below the CHANNEL bar in the main screen.
change to the screen shown above. To access the channel assignment menu, first touch the SET FREQUENCY button on the screen. You will notice that one of the digits in the FREQUENCY bar will now have a black, blinking cursor. Using the left and right arrows below the FREQUENCY bar, navigate the blinking cursor to the digit that will be changed first. In the screen shot above for example, the current frequency of channel 2 is 6438.000 MHz, however you want to change this to 6455.000.
