1 1 About the HDX-1100 The KamelyonTM HDX-1100 high power digital microwave transmitter is a ruggedized unit designed to support high quality video and data transmission in airborne and mobile applications, where vibration, shock, humidity, and temperature swings are everyday occurrences. The HDX-1100 is compliant with aircraft industry mounting standards, making it perfectly suited for airborne or ground based mobile platforms. Typical applications include real time video for law enforcement, public safety, fire, utility, and other agency based surveillance tasks. The HDX-1100 includes an H.264/MPEG-4 encoder that provides standard or high definition (SD or HD) video on DVB-T/ COFDM, or Vislink RangeMasterTM single carrier modulation. An MPEG-2 encoder option is available to support legacy receivers. Video inputs may be configured for composite NTSC or PAL in standard analog formats, or digital video in SDI, HD-SDI, or ASI formats. Other inputs include two full range audio channels, and an RS-232 data channel. The transmitter RF output is 8W in high power mode, and about 4 W in low power mode. The HDX-1100 may be operated via the touch screen user interface (see Section 4), however it is typically controlled by an optional aircraft remote panel (RCU) (see Section 5). Initial HDX-1100 programming and presets should be configured via PC using the integrated web browser utility (see Section 6). 2 Operating in Safety Guidelines for safe operation are derived from OET bulletin 65, August 1997, as recommended by the Federal Communications Commission (FCC). WARNING High levels of RF power are present in the unit. Exposure to RF or microwave power can cause burns and may be harmful to health. Remove power from the unit before disconnecting any RF cables and before inspecting damaged cables and/or antennas. Avoid standing in front of high gain antennas (such as a dish antenna) and never look into the open end of a waveguide or cable where RF power may be present. The HDX-1100, operated without an antenna will not create RF energy exceeding 1.0 mW/cm2, the FCC limit for exposure. Connecting an antenna to the unit greatly enhances the potential for harmful exposure, and you must maintain a certain distance from the radiator. The following table shows the Maximum Permissible Exposure (MPE) safe distances from the antenna.

Observe all applicable state and federal regulations when using this transmitter. To perform calculations to understand the safe exposure margin (MPE), use the following formula suggested by OET 65. The calculations provided are for common antennas often used in the mobile microwave environment. Calculating MPE EIRP = P * (10 ^ (G / 10)) = (antilog of G/10) * P P = RF power delivered to the antenna in mW G = Power gain of the antenna in the direction of interest relative to an isotropic radiator R = distance to the center of radiation of the antenna in centimeters S = MPE in mW/cm² (milliwatts per square centimeters) Conversions dBi to numeric gain = Antilog (dBi/10) Feet to centimeters = Feet * 30.48 Centimeters to Feet = cm * .0328 4 π = 12.57 User Input RF power delivered to the antenna = Watts Antenna gain (referenced to isotropic antenna) = dBi Distance from the center of radiation = Feet Calculation steps: 1. [P] RF power input. Watts to milliwatts = Watts * 1000 2. [G] Antenna gain dBi. Numeric gain = Antilog (dBi/10) 3. [EIRP] Multiply P * G 4. [R] Centimeters to feet = Centimeters * .0328 5. Square R 6. Multiply R² * 4π 7. [S] Divide (R² * 4π) into EIRP S = Power Density in milliwatts per square centimeters. Note At frequencies above 1500 MHz, S must not be greater than 1.

6 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 MECHANICAL OUTLINE There are two possible mounting configurations, which should provide an installer with enough flexibility to work in most situations: 1) For situations where the transmitter will be mounted on a flat surface, four captive nuts have been installed in the transmitter side plate. 2) An optional aircraft mounting kit (part # 9000372) may be ordered. The kit includes an ARINC compliant low profile tray with quick release clamps, and removable spacers. Optional 9000372 3/8 ATR mounting kit with removable spacers
7 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. HDX-1100 in optional 3/8 ATR tray installed on existing shelf without spacers
8 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. You can select from up to nine preset configurations. The last four are configured as factory defaults, but may be changed to suit your needs. Up to 15 RF channels may be configured To select a preset, do the following: 1. Press the UP or DOWN buttons below the PRESET bar in the display 2. The new PRESET selection will remain so until it is changed. 3. Press the UP or DOWN buttons below the CHANNEL bar in the display 4. The new CHANNEL selection will remain so until it is changed. 4.2 Selecting the RF Output Level The HDX-1100 recalls the most recently saved RF output power level when it is powered up. To select between high or low power for the RF output level, do the following: 1. Press PA HIGH/LOW key to toggle between HIGH or LOW RF output level. 2. Press the PA ON/OFF button to toggle between RF on and RF off. NOTE: When changing channels, the PA will automatically shut off to avoid interference with other users, as the frequency changes. It must be manually turned on again once the frequency change is complete (the display will change to new channel selection). Please refer to section 8 for complete information on using the local touch screen controller
9 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. The following table provides detailed descriptions of the functionality of each push button and rotary switch, plus an explanation of each LED. Presets and channel numbers are both shown in LCD window displays.
10 Function Name Description Push Buttons RF ON/OFF Switches the transmitter RF output between standby (STBY) and transmit (XMIT) conditions. In STBY, the RF output is zero. BRIGHTNESS Sets the display brightness to high (H), low (L), or automatic (A; light sensing). LED Displays 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. DC OK Indicates DC Power is applied to the Remote Control Panel and transmitting. FAULT Indicates an error condition in the HDX-1100 transmitter. HI Indicates the HDX-1100 is in high RF output mode. LO Indicates the HDX-1100 is in low RF output mode. ENCRYPTION Indicates the HDX-1100 is transmitting an encrypted signal VIDEO Indicates the presence of a video signal at the HDX input Rotary Switches RF HI/LOW Sets the HDX-1100 to high (HI) or low (LO) RF power output mode. PRESET Select from 1 to 9 presets. CHANNEL Select from 1 to 15 channels LCD Display PRESET Displays the current preset number. CHANNEL Displays the current channel number. Use a 9-pin RS-232 null-modem cable to connect the communication path between the RCU and the HDX-1100. A receptacle at the rear of the controller supplies DC power to the RCU. Vislink provides the 2-pin Weidmuller connector (Part # 52104-2) to connect to the power receptacle at the rear of the controller. The required power range is from +10—+50 Vdc (negative ground only). NOTE: During initial power up, the RCU will display a C until the HDX-1100 processor completes a boot up and self check sequence; this is normal. If the C does not disappear within one to two minutes, the HDX-1100 has lost power or a communications error has occurred; check the circuit breakers, and power and serial cable connections. To facilitate updating or servicing an HDX-1100 transmitter, we recommend that the transmitter and RCU panel are fed from different circuit breakers. In normal operation, power should be applied to the RCU first, or to both units simultaneously. To use local (front panel) control of the HDX-1100 transmitter, the RCU should be off (not powered) when the transmitter is first powered up. The RCU always has priority, and will assume control if power is applied while the transmitter is on and in local control mode. At the same time, the front panel will freeze and be non-responsive even though the RCU is functioning perfectly. To return to local control, turn both units off, and re-boot only the transmitter.
11 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. A list of factory default presets is included in Appendix 1 at the end of the manual. WARNING: Do not attempt to modify, delete, or create new pre-sets until you have a complete understanding of the video set-up menus described below. If you have any questions in this regard, please contact Vislink customer service. To set up the HDX-1100 transmitter with a PC, do the following: 1.

17 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. To initiate programming or make a change, click on Preset Number and choose the preset you wish to program or change from the drop down menu. Enter the new text in the Preset Text dialog box, and click the
18 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. MODULATION SETUP SCREEN 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. The maximum available bit rate is directly related to the modulation type and the channel bandwidth. The following tables provide a complete summary of modulation settings for both 6 and 8 MHz DVB-T bandwidths as a function of bit rate. In order to comply with FCC emission standards, a 6 MHz DVB-T bandwidth is the maximum allowed in an 8 MHz wide RF channel, while an 8 MHz DVB-T bandwidth can be used in a 10 MHz or wider RF channel. A 10 MHz DVB-T bandwidth can support a total bit rate 33% higher than an 8 MHz channel, if all other factors are equal.

20 NOTE: External encoder required for bit rates in yellow highlight. Other factors that impact the total available bit rate are the code rate and the guard interval settings. Coding Rate Setting: This setting determines the amount of forwa rd error correction used to reduce video data loss under adverse conditions . If the code rate is set to ½, this means that half of the available data rate is being used for error correction, while the rest is available for video. A code rate of 1/2 uses the most bandwidth for error correction, but provides the highest degree of protection against video breakup. Guard Interval: The primary purpose of the guard interval is to provide resistance to multipath and co-channel interference. Longer guard intervals are used in dense metro areas, where high levels of multipath are expected. A guard interval of 1/4 is the longest, while 1/32 is the shortest. NOTE: W hen programming an HDX-1100, a good rule of thumb is to program several presets with varying amounts o f error correction to be able to quickly switch quickly from a very robust, low data rate setting, to a less robust but higher-speed setting. 6.5 VIDEO AND AUDIO INPUT SETUP The video and audio inputs must be configured for each preset. To initiate this procedure, click on MPEG-2 or MPEG-4 in the bar at the top of the screen, and then click on Video on the left side of the screen. Two dialogue boxes will appear: Video In, and, Encryption. See next graphic for details. IMPORTANT: When equipped with the MPEG-2 encoding option, HDX-1100 presets may be programmed all in MPEG-2 mode, all in H.264/MPEG-4 mode, or as a mix of the two. For example, the first five presets may be programmed for MPEG-2 encoding, while the remaining four are programmed for H.264/MPEG-4 encoding. Video Settings: Click on Video In and select the desired parameters from the drop down table. Available parameters include the input configuration, such as composite or SDI, as well as video resolution. MPEG-2 settings differ from MPEG-4 settings, and require additional choices to be made, including NOTE: Input A is the normal video input and must always be set up. When using the
21 DoubleVision option, Input B must also be set up. Video and Encryption Mode set-up Screen If encryption is to be used, select Encryption from the Video drop down menu, and configure the encryption mode and key as required for encrypted preset, and click Submit.. Note: For 128-bit encryption, enter 32 hexadecimal characters. For 256-bit encryption, enter 64 hexadecimal characters.
22 6.6 CHANNEL SETUP 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. Once you have completed and checked the frequency entry, click the submit button and the new frequencies will appear in the dialog boxes on the left side of the screen.
23 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.

The touch screen provides the ability to recall and review and/or change the frequency of channel presets, turn the power amplifier on and on, switch between high power and low power modes, and gives visual feedback to maintenance personnel for each of the described actions. Future software updates will provide additional set-up capability, including the ability to set modulation constellation, guard interval, and Forward Error Correction, and will support saving any changes to a selected or new preset. NOTE: The HDX-1100 touch screen will allow local control only when the remote control (RCU) panel is disconnected, or powered down. If the RCU panel is turned on or connected while the HDX-1100 is powered on, the RCU will take priority for as long as the units are powered on. The local touch screen will continue to display the last setting, but will not longer control transmission parameters. To regain local control, the HDX-1100 must be powered down, and the RCU must be turned off or disconnected, before powering up the HDX-1100 again. Once the boot-up sequence is completed in local control mode, the main screen will be shown, as illustrated in 8.1 below.

32 Appendix 1 The table and chart below summarizes the FCC channel plan for the 6.5 GHz band, as specified in part 101 of the commission’s rules and regulations. Please note the restrictions on modulation bandwidth for the 8 MHz channels, as well as use of offsets within the 25 MHz channels. For US domestic applications, this is the default channel plan that is loaded into an HDX 1000 prior to shipment. This plan may be modified by the user to suit specific requirements. For application outside of the United States, consult with your local regulatory agencies.
