OVERVIEW1.1 INTRODUCTIONTroll System’s Linkbox is an airborne communications and data link that operates SkyLink Antenna systems and related equipment. Available in standard ATR units it features a built-in touchscreen monitor and a graphical user interface (GUI) that enables the user to configure and control the aircraft’s entire microwave transmission system including transmitting radios, tracking antennas, stabilized cameras, sensor payloads, Ethernet routing, power distribution, mapping and control settings.  2. SAFETYThe following safety considerations are intended as a guide for safe usage of this system per FCC guidelines and the manufacturer. Review the following information for safe usage of this product.2.1 GENERAL SAFETY PRECAUTIONSThe following safety requirements, as well as local site requirements and regulations, must be observed by personnel operating and maintaining the equipment described in this manual to ensure awareness of potential hazards. This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy. If not installed and used in accordance with this manual as well as federal and state regulatory requirements, it may cause harmful interference to radio communications. It is the responsibility of the owner of operator of this equipments to ensure proper and safe usage of this equipment in accordance to the state and federal regulatory requirements. Troll Systems Corp cannot be held responsible for any harm or injury resulting from the use of this equipment. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.The following general safety precautions are not related to any specific procedures and therefore do not appear elsewhere in this publication. They are, however, precautions that personnel need to understand and apply when operating or repairing equipment. Installation, operation, and maintenance should be performed only by qualified personnel.
User Manual 6.5 GHz RF Linkbox for Tracking Antenna - Troll Systems Corporation 6 Document 200610D - 7/11/17 2.1.1 Know and Comply with Local, State, and Federal Safety RequirementsAll personnel handling and using this equipment should be familiar with all local, state, and federal safety requirements applicable to the equipment, processes, and materials you use during maintenance. Before using any substances or materials marked toxic or hazardous, always refer to the Material Safety Data Sheets (MSDS) for that substance/material for any special protective equipment, handling, and/or disposal requirements.2.1.2 Do Not Service or Adjust AloneDo not start a maintenance or adjustment procedure if that procedure requires more than one technician to be safely performed. It is particularly important that such work not be performed in a remote area away from other qualified personnel who may be needed to render assistance. When a maintenance task requires two or more personnel to be safely accomplished, delay the task until qualified personnel are available to assist you.2.2 RF SAFETY CONSIDERATIONS AND PRECAUTIONSThe guidelines for safe operation herein are derived from OET bulletin 65, August 1997, as recommended by the Federal Communications Commission (FCC).When this system is operated without an antenna, it will not create RF energy exceeding 1.0 mW/cm2, which is the FCC limit for exposure. Connecting an antenna to the unit greatly increases the potential for harmful exposure to microwave radiation and all personnel must maintain a minimum distance from the radiator per the amount of radiation emanating from the transmitter and the antenna.CAUTION: Any modifications made to the LinkBox not approved by Troll Systems Corporation will void the user’s authority to operate this equipment.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 prior to 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.
 RF SAFETY CONSIDERATIONS AND PRECAUTIONS6.5 GHz RF Linkbox for Tracking Antenna - Troll Systems CorporationDocument 200610D - 7/11/17 72.2.1 Applicable Safe Distances to Active RFThe Maximum Permissible Exposure (MPE) safe distances from the antenna with a gain of 12 dBi is as follows:• The safe distance measured in centimeters (cm) is: 109.748 cm• The safe distance measured in inches (in) is: 43.208 inTo calculate safe distances is situations where paragraph 2.2.1 is not applicable, use the following formula suggested by OET65. The calculations provided are for common antennas often used in the mobile microwave environment.2.2.1.1 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 centimeter)• Conversions— dBi to numeric gain = Antilog (dBi/10) — Feet to centimeters = Feet * 30.48— Centimeters to Feet = cm*.0328—4=12.57• User Input— RF power delivered to the antenna = Watts — Antenna gain (referenced to isotropic antenna) = dBi— Distance from the center of radiation = FeetNOTE: Hazardous RF radiation limits and recommended distances may vary by country. Observe all applicable state and federal regulations when using this transmitter.

[G] Antenna gain dBi. Numeric gain = Antilog (dBi/10)3. [EIRP] Multiply P * G2.3 ELECTRICAL POWER / SHOCK HAZARDSAlways verify that electrical power is disconnected and that applicable safety procedures have been followed before doing maintenance on any electrical/electronic equipment. High voltage electrical energy is stored in some electrical equipment (electrolytic capacitors, UPS batteries, etc.) even after the source of primary external power has been disconnected. Always remove external power, deactivate equipment, or discharge the potential to ground (when applicable) before working on the equipment.If a high-potential insulation test is required, follow the procedures and precautions outlined in the appropriate National Electrical Manufacturing Association (NEMA) standards. Check with the area supervisor if unfamiliar with these standards, specific equipment, or procedures.When troubleshooting a system with electrical power applied, first verify that all personnel in the hazard area are advised, that the equipment is tagged, and/or that an assistant is posted at the point of power control.WARNING: Potentially lethal voltage/current is present throughout many electrical installations. Maintenance personnel shall employ positive power lockout devices and post all required warning tags/signs when applicable to ensure that no unauthorized application of power can occur during maintenance. Failure to heed this warning could result in serious injury or death by electrocution.
 ELECTRICAL POWER / SHOCK HAZARDS6.5 GHz RF Linkbox for Tracking Antenna - Troll Systems CorporationDocument 200610D - 7/11/17 92.3.1 Electrostatic Discharge Sensitive (ESDS) ComponentsComputers, microprocessors, and other solid state components (circuit cards, I/O boards, etc.) which are not clearly marked with the ESDS symbol will be handled as ESD sensitive components until determined otherwise. Retain protective ESDS packing and shipping bags, containers, non-conductive foam pads, etc. (see Figure 2–1) for use in the return of repairable components.Figure 2–1.  Electrostatic Discharge PrecautionsCAUTION: Beware of electrostatic buildup. Delicate solid-state Integrated Circuits (ICs) can be damaged by improper handling procedures. Use proper electrostatic safeguards when installing/removing circuit cards and handling ESD sensitive assemblies. As required, wear a grounded wrist strap, use anti-static floor and table mats, and minimize the handling of sensitive solid-state devices. Keep all ESD sensitive components in their original containers until ready for use. Always discharge personal static before handling ESD sensitive components and do not slide solid state devices over any surface. Handle plug-in card assemblies only by their non-conductive edges.Minimize Handling Keep parts in original containers until ready for use.Discharge personal static before handling devices.Handle each device by the devices’ body, not the contacts Use anti-static containers for handling and transportDo not slide devices over any surfaceAvoid plastic, vinyl and Styrofoam in work areaWhen removing plug-in assemblies, handle only by non-conductive edges. Never touch open edge connectors except at static-free work stations. Placing shorting strips on edge connector usually provides protection to installed devices.Handle devices only at a static-free work station.Only anti-static type solder suckers should be used.Only grounded tip soldering irons should be used.

If the coding rate is set to 1/2,then half of the available data rate is being used for error correction and the remaining available data for video. NOTE: a code rate of 1/2 consumes most of the bandwidth for error correction, but also provides the highest degree of protection against video interference.** Guard Interval: The guard interval provides resistance to multipath and co-channel interference. Longer guard intervals are used in areas where high levels of multipath are found such as dense metro areas. A guard interval of 1/4 is the longest while, conversely, a guard interval 1/32 is the shortest1/2 13.063 14.515 15.369 15.8342/3 17.418 19.353 20.491 21.11264-QAM 3/4 19.595 21.772 23.053 23.7515/6 21.772 24.191 25.614 26.3907/8 22.861 25.401 26.895 27.710Table 5–4.
