This symbol indicates the presence of a potential RF hazard. MM-009804-001 1.2 REGULATORY 1.2.1 Maximum Permissible Exposure Limits DO NOT TRANSMIT with this base station and antenna when persons are within the MAXIMUM PERMISSIBLE EXPOSURE (MPE) Radius of the antenna. The MPE Radius is the minimum distance from the antenna axis that ALL persons should maintain in order to avoid RF exposure higher than the allowable MPE level set by the FCC. FAILURE TO OBSERVE THESE LIMITS MAY ALLOW ALL PERSONS WITHIN THE MPE RADIUS TO EXPERIENCE RF RADIATION ABSORPTION, WHICH EXCEEDS THE FCC MAXIMUM PERMISSIBLE EXPOSURE (MPE) LIMIT. IT IS THE RESPONSIBILITY OF THE BASE STATION LICENSEE TO ENSURE THAT THE MAXIMUM PERMISSIBLE EXPOSURE LIMITS ARE OBSERVED AT ALL TIMES DURING BASE STATION TRANSMISSION. THE BASE STATION LICENSEE IS TO ENSURE THAT NO BYSTANDERS ARE WITHIN THE RADIUS LIMITS. 1.2.2 Determining MPE Radius THE MAXIMUM PERMISSIBLE EXPOSURE RADIUS is unique for each site and is determined based on the complete installation environment (i.e. co-location, antenna type, transmit power level, etc.). Determination of the MPE distance is the responsibility of the VIDAMAX user. Calculation of the MPE radius is required as part of the installation. The Limit for Uncontrolled Exposure Power Density (Pd ) is 10 W/m2 for fixed mounted device. The M/A-COM 4.9 GHz VIDAMAX Base Station is a fixed mounted radio. After installation and commissioning, the safe distance from the 9 dBi omni-directional antenna is greater than 20 cm (8-inches). 1.2.2.1 MPE Calculation for omni-directional Antenna This MPE Minimum Distance Calculation is based on using a 9 dBi gain omni-directional antenna mounted directly to the base station RF port. Basic M/A-COM 4.9 GHz VIDAMAX Base Station specifications: P: Maximum Peak Conducted Power = 27 dBm G: Maximum Omni Antenna Gain = 9 dBi Frequency Range = 4.94 to 4.99 GHz R: Minimum Distance between User and Antenna = 0.2 m Equation from FCC: Pd = P * G / ( 4 * π * R 2 ) Pd = 0.5 W * 7.94 / (4 * 3.1415926 * 0.2 2) = 7.89 W / m2 < 10 W / m2 MM-009804-001 The calculation indicates that the minimum 0.2 meter distance between user and the omni-directional antenna (directly mounted to the base station RF port) is required when operating the M/A-COM 4.9 GHz VIDAMAX Base Station. 1.2.2.2 MPE Calculation for Directional Antenna This MPE Minimum Distance Calculation is based on using a directional antenna with more than 9 dBi antenna gain. Basic M/A-COM 4.9 GHz VIDAMAX Base Station specifications: P: Maximum Peak Conducted Power = 27 dBm; G: Maximum Omni Antenna Gain – Cable Loss = 27 dBi – 1 dB = 26 dBi; (Use numerical GN value for the calculation ): GN = 10 ^ (G /10)); For G = 26 dBi, GN = 10 ^ (26 /10) = 398 Frequency Range = 4.94 to 4.99 GHz; Rmin: Minimum Distance between user and antenna to comply with FCC MPE Level (10 W / m2 ); Equation from FCC: Pd = P * G / ( 4 * π * Rmin 2 ) Rmin = SQRT( 0.5 W * GN / (4 * 3.1415926 * 10 ) )= SQRT ( 3.9789E-3 * GN ) Rmin = 1.26 m, for G =26 (i.e., GN = 398 ) The calculation provides guidelines for users to estimate the minimum safe distance when a high gain antenna is connected to the M/A-COM 4.9 GHz VIDAMAX Base Station. The user should always keep a safe distance from antenna greater than 20 cm or SQRT (3.9789E-3 * GN).

M/A-COM’s new VIDAMAX broadband network applies the open standard IEEE-based wireless broadband communications protocol of 802.16 to the 4.9 GHz band, thereby providing true Quality-ofService (QoS) while operating on contention-free licensed frequencies. The VIDAMAX Base Station provides hardened, public safety grade base station infrastructure for M/ACOM’s 4.9 GHz VIDAMAX broadband network. 4.1 VIDAMAX SYSTEM OVERVIEW VIDAMAX provides integrated public safety grade wireless broadband video and data services for missioncritical applications. VIDAMAX combines the security of the licensed 4.9 GHz public safety frequency band with robust 802.16 technology to create a true public safety broadband network. With this state-ofthe-art network, public safety customers can implement applications such as streaming video, web applications, economical licensed LMR backhaul, and other bandwidth intensive applications. Since the network provides guaranteed Quality of Service (QOS), it is especially suited for applications such as video surveillance, perimeter control, and mobile command. VIDAMAX is integrated with M/A-COM’s VIDA network allowing seamless sharing of network management and administration. Figure 4-1: VIDAMAX Wireless Broadband Video and Data Services 4.2 THE VIDA NETWORK SOLUTION By leveraging advances in standards-based Information Technology, M/A-COM has developed a unique IP-based network solution to solve the many challenges that critical communications users are confronted with. These challenges include delivering different types of information reliably, ensuring technology does not become quickly obsolete, and being able to acquire equipment from multiple vendors. VIDAMAX addresses these challenges and is part of a total network solution called VIDA (Voice, Interoperability, Data, and Access). VIDAMAX is fast, secure and standards based and will allow critical communications customers to obtain access to information that its users need today and into the future. 16 MM-009804-001 Figure 4-2: VIDA Network Solution Figure 4-2 depicts a picture of the VIDA Network Solution and how many different communications systems are built on the solid foundation of a wide-area IP network. This provides an open architecture for the integration of public safety voice and data airlink protocols including OpenSky, EDACS, and P25IP. This open architecture enables mission critical communications customers to have one integrated solution to meet numerous voice and data needs. 4.3 THE VIDAMAX NETWORK VIDAMAX is the broadband extension of VIDA and as a complete broadband distribution system, can serve as the airlink to the user, as well as a wireless extension of the core IP network upon which the VIDA network is based (Figure 4-2). VIDAMAX integrates the sophisticated Quality-of-Service (QoS) and solid security of the 802.16-2004 (WiMAX) protocol with the licensed protection of the 4.9 GHz public safety band to provide public safety grade wireless broadband data services for mission critical applications. 17 MM-009804-001 Figure 4-3: VIDAMAX Broadband Network Figure 4-3 illustrates a typical deployment scenario of the VIDAMAX 4.9 GHz broadband network. It provides secure, public safety grade broadband services to both fixed and mobile clients. Conceptually, the system can be seen as extending the enterprise WAN to remote locations using the licensed 4.9 GHz public safety band. Some common applications for this system include: 4.4 • Remote surveillance video • Mobile broadband access to vehicles (“Hot Spots”) • Connection of remote precincts to the enterprise and/or VIDA network • Backhaul of IP based LMR traffic VIDAMAX NETWORK COMPONENTS/FEATURES The basic architecture of the 4.9 GHz VIDAMAX network is a point-to-multipoint network. A system consists of one or more base station(s) and at least one client (Figure 4-3). There are two configurations of client devices; fixed and mobile. Fixed client devices are usually mounted outdoors with directional antennas and have a range of up to 10 miles. Mobile clients are vehicle mounted and use an omnidirectional antenna. The range of a mobile client to base station is a few hundred meters. 18 MM-009804-001 Figure 4-4: Network diagram of small VIDAMAX system The base station implements the 802.16-2004 protocol in a 5 MHz channel, delivering an over-the-air throughput from 4 to 19 Mbps. All communication over this channel is scheduled by the base station, with contention slots provided for subscriber stations to request bandwidth. This coordinated scheduling feature of the protocol provides significant advantages such as: • Minimizes contention between clients • Maximizes channel utilization • Maximizes ability to coordinate frequency usage among users • Enables guaranteed bandwidth services for critical multimedia applications. The use of a scheduling protocol also makes the network more resilient to simple denial of service attacks that can disable other broadband networks. To allow for great flexibility when designing a network, up to 16 “connections” can be established between the base station and each client, with a different QoS for each connection. Low priority processes (such as email) can be mapped to best effort services while high priority processes (such as 19 MM-009804-001 streaming video or LMR backhaul) can be mapped to Unsolicited Grant Services (UGS) to provide guaranteed throughput. 4.5 4.9 GHz VIDAMAX BASE STATION The VIDAMAX Base Station provides hardened, public safety grade base station infrastructure for M/ACOM’s 4.9 GHz VIDAMAX broadband network. The VIDAMAX base station implements the IEEE 802.162004 protocol to deliver an over-the-air throughput from 4 to 19 Mbps. All communication over the wireless channel is scheduled by the base station, with contention slots provided for subscriber stations to request bandwidth. Up to 16 “connections” can be established between the base station and each subscriber in the network, with different QoS for each connection, allowing for great flexibility when designing a network. Low priority processes (such as email) can be mapped to best effort services while high priority processes (such as streaming video or LMR backhaul) can be mapped to unsolicited grant services (UGS) which offer guaranteed throughput. Network convergence is provided in the form of 802.16 classifier rules that ensure network level QoS over the airlink. Base station configuration and management is provided via a browser interface to M/A-COM’s Unified Administration System (UAS). The base station additionally supports localized SNMP management for single/limited site deployments. SNMP attributes are defined in the MIB II, the 802.16 and the M/ACOM using an open MIB. Base stations may optionally be configured as DHCP and/or TFTP servers. All subscriber station management can be performed over the air. The VIDAMAX base station provides strong protection against unauthorized network access through the use of certificates for subscriber authentication. Authentication keys are distributed using RSA Public Key encryption. The cryptographic methods provided by the security sub layer use DES, 3-DES, and AES algorithms. The VIDAMAX Base station is housed in a hardened, outdoor enclosure that satisfies IP66 requirements for outdoor deployments. The base station is designed with flexible mounting configuration to allow for both pole mount and fixed structure mounting. To provide for flexible RF deployment configurations, the base station provides options for (1) direct mounting of an omni-directional antenna on the base station (2) direct mounting of a directional antenna on the front face of the base station and (3) remote mounting of an antenna through the connection of an RF cable to the base station. The base station comes in two power/network configurations: one with 110 VAC power and RJ-45 Gigabit Ethernet configuration and one with +24 VDC power and 100-BaseFX fiber configuration. Figure 4-5: VIDAMAX Base Station 20 MM-009804-001 4.5.1 Summary of Key Features 4.5.1.1 Airlink Features The VIDAMAX Base Station implements the 802.16-2004 protocol to deliver an over-the-air throughput from 4 to 19 Mbps. All communication over the wireless channel is scheduled by the base station, with contention slots provided for the VIDAMAX Client to request bandwidth. A protocol with coordinated scheduling provides significant advantages such as: • minimizing contention between clients • maximizing channel utilization • enabling guaranteed bandwidth services for critical multimedia applications. The use of a scheduling protocol also makes the network more resilient to simple denial of service attacks that can disable other broadband networks. Up to 16 “connections” can be established between the base station and each client in the network, with different QoS for each connection, allowing for great flexibility when designing a network. Low priority processes (such as email) can be mapped to best effort services while high priority processes (such as streaming video or LMR backhaul) can be mapped to unsolicited grant services (UGS) which offer guaranteed throughput. 4.5.1.2 Network Features Network convergence is provided in the form of 802.16 classifier rules that ensure network level QoS over the airlink. Network management is provided via a browser interface to M/A-COM’s UAS. The base station additionally supports localized SNMP management using an open MIB. Base stations may optionally be configured as DHCP and/or TFTP servers. All VIDAMAX Client management can be performed over the air. 4.5.1.3 Security Features The VIDAMAX base station provides strong protection against unauthorized network access through the use of certificates for client authentication. Authentication keys are distributed using RSA Public Key encryption. The cryptographic methods provided by the security sublayer use DES, 3-DES, and AES algorithms. 21 MM-009804-001 4.6 VIDAMAX BASE STATION INTERFACES Figure 4-6: VIDAMAX Base Station Interface Diagram 4.6.1 Standard Base Station (AC Powered) RF Antenna Port: • Connector: N-type Female • Impedance: 50 Ohm 110 V AC Power Port: • Industrialized 3-Pin Connector (Conxall Part No. 4180-3PG-3XX) DATA Ports: • Two Industrialized RJ-45 Connectors • One port for Service only GPS Antenna Port: 22 • Connector: SMA Female • Impedance: 50 Ohm MM-009804-001 4.6.2 Special Hardened Base Station (DC Powered) RF Antenna Port: • Connector: N-type Female • Impedance: 50 Ohm • Internal Lightning Suppressor 24 V DC Power Port: • Industrialized 3-Pin Connector (Conxall Part No. 4180-3PG-3XX) • Internal Lightning Suppressor DATA Ports: • LC Industrialized Fiber Optic Connector • One port for Service only GPS Antenna Port: • Connector: SMA Female • Impedance: 50 Ohm • External Lightning Suppressor (optional) 23 MM-009804-001 4.7 VIDAMAX Base Station Antenna Options The VIDAMAX Base Station allows users to choose many different antenna types to meet their application requirements. Depending on the location and site planning, a directional antenna can significantly extend the effective coverage area of the base station. For example, one can choose a high gain directional antenna to effectively cover a long strip of highway, in the meantime avoiding the area further away from the highway (where coverage is no longer needed) to reduce the total number of base stations. Another example could be using a 90-degree sectional antenna to effectively cover a town-center area while avoiding rural regions where no coverage is required. The user can directly mount an omni-directional antenna to base station RF antenna port. Additionally, four mounting holes are provided on the VIDAMAX Base Station chassis to allow a directional antenna to be mounted on an optional bracket. Finally, the user can choose other industry means for mounting a directional or omni-directional antenna separate from base station. In this case, however, the total length of cable should not exceed 5 feet. Choose high quality 50-Ohm cable with the lowest loss at 5 GHz. CAUTION The four antenna mounting holes on VIDAMAX base station can sustain a pulling force of 100 mph (160 km/h) sustained wind and survive wind gusts to 136 mph (220 km/h). It is the user’s responsibility to estimate the force induced by antenna to ensure the integrity of the product. Basic Antenna Requirements: Omni Antenna: Vertical Polarization 9 dBi Maximum Gain Directional Antenna: Linear Vertical 26 dBi Maximum Gain (Reduction of Transmitter Power is required if the Effective Maximum Antenna Gain is greater than 26 dBi.)

It is recommended that this antenna be installed with a minimum of 10 feet of LMR-400-UF antenna feeder cable (Cable Loss = 1.1 dB at 5 GHz). The effective Antenna Gain in this case will thereby be less than 26 dBi. Also, due to its size, the MT-466003 needs to be individually mounted on the pole. 25 MM-009804-001 UNPACKING AND CHECKING EQUIPMENT Before unpacking, installing or operating the VIDAMAX equipment, read this section of the manual thoroughly. It contains detailed unpacking and handling instructions, and safety precautions to protect users and equipment. 5.1 UNPACKING EQUIPMENT The VIDAMAX equipment may be shipped in separate transit packages. The associated cabling and accessories for each unit, if any, may also be shipped in separate containers. When unpacking the equipment, check the contents against the packing list. Contact your M/A-COM VIDAMAX equipment representative and the carrier if any discrepancies are noted. Save the shipping cartons and packing materials in case the equipment needs to be shipped back to the M/A-COM for service. There are no user serviceable components within the VIDAMAX radio equipment assemblies. These assemblies contain ESD sensitive components and should only be serviced by M/A-COM qualified personnel. 5.2 INSPECTING AND INVENTORYING EQUIPMENT Carefully unpack the equipment and examine each item. If there is any damage to the equipment, contact the carrier immediately and have their representative verify the damage. If you fail to report the shipping damages immediately, you may forfeit any claim against the carrier. CAUTION 26 After removal from the carton, examine the VIDAMAX equipment for broken, damaged, loose, or missing parts. Examine the RF connector(s), circular power connector and ground lug for cracks, bent or damaged threads, or damage to any paint or seals. If any are noted, contact the M/A-COM Customer Resource Center immediately. Any unauthorized attempts to repair or modify this equipment will void the warranty and could create a safety hazard. MM-009804-001 PLANNING THE INSTALLATION 6.1 ENVIRONMENTAL EVALUATION Before installing the VIDAMAX Base Station, the System Engineer and installer should plan the site selection before attempting to install the base station. Since high frequencies do not readily pass through trees or buildings, consideration should be given to the following: 6.2 • Ensure there are no obstructions (such as buildings or trees) in the radio path between base station and fixed client units • Ensure the any future building construction or tree growth will not obstruct the radio path • Ensure there is sufficient clearance around the Fresnel Zone so there is minimal interference from obstacles along the radio propagation path • Ensure the installation adheres to any local building codes and permits • Ensure sufficient electrical power is available at the installation site • When using directional antennas, align the base station antenna to maximize the received signal strength indication (RSSI) • Ensure area around an omni-directional antenna is clear (at least 30 inches) so as not to distort the RF pattern • Locate the base station away from any sources of interference that could degrade the performance of the base station • Ensure the base station and fixed clients are within maximum coverage range of reception • Maximum standard CAT-5 cable length connecting the base station to the Ethernet LAN is 100 meters and maximum antenna cable length is 5-feet POLE-MOUNT INSTALLATIONS The VIDAMAX Base Station is designed to accommodate pole mounting. Typically, pole mounting means mounting the base station on a light post (horizontally) or telephone pole (vertically) as shown in Figure 6-1. A kit containing two mounting brackets and hardware for attaching the base station to a pole can be optionally purchased. The bracket accommodates mounting on a pole with a diameter in the range of one (1) to six (6) inches. The installer must provide straps necessary to secure the base station brackets to the pole. CAUTION When mounting the base station on a pole, the installer must ensure the mounting bands are strong enough (resistance to rotation) so the base station can withstand 100 mph (160 km/h) sustained wind and survive 136 mph (220 km/h) wind gusts. 27 MM-009804-001 Figure 6-1: Pole Mounting the VIDAMAX Base Station 6.3 ELECTRICAL POWER There are two configurations of the base station. The AC version is configured to accept 110 VAC power from standard U.S. utility power distribution. The DC Hardened version of the base station accepts +24 VDC (negative ground) power from a power supply or battery. 6.3.1 AC Power An AC powered VIDAMAX base station requires at least 2 amperes of electrical service: 6.3.2 DC Power A DC powered base station requires a +24-volt (nominal) DC power source. This source must have a continuous-duty current rating of at least 3 amperes. Refer to Section 2, Specifications for additional information. 6.4 SITE GROUNDING Installers should review the recommended grounding procedures in the Site Grounding and Lightning Protection Guidelines manual, AE/LZT 123 4618/1 and ensure a suitable ground is installed between the base station ground lug and earth ground. Grounding must also be in compliance with any local and national electrical codes. 28 MM-009804-001 INSTALLATION The VIDAMAX Base Station resides in a Die Casting Metal Chassis to meet tough environmental conditions. The user can choose different antenna types (omni-directional or directional) depending on the application. It is preferred that the user specifies 50-Ohm low loss (@5GHz) cable with minimum length (5-feet maximum) between the antenna connector and antenna port on the base station to avoid further loss of RF power. The base station is available as either as +24 VDC (hardened) or 110 VAC version. The total power consumption is less than 60 Watts. For the AC version, the radio uses weatherproof RJ-45 for connector as data and network connections. M/A-COM recommends using the DC hardened version of the VIDAMAX base station in the areas that experience frequent thunderstorms. In this version, weatherproof LC fiber-optic connections are employed, and lightning protection is internally provided within the base station for the RF antenna and DC power ports. Additional external lightning protection for the GPS antenna port may optionally be installed. Both the RJ-45 and LC fiber-optic connectors achieve weatherproof properties only when properly mated with M/A-COM approved cabling. For the Service port, the dust cap is to be installed in normal operation. 7.1 TOOLS AND TEST EQUIPMENT REQUIRED The following tools and test equipment are recommended for installing and testing the VIDAMAX Base Station: • Common hand tools, including screwdrivers, wire cutters, pliers, etc. • Modular Plug Tool, 3-231652-0 (Tyco/Electronics-AMP) Includes; Hand Tool, 2-231652-0 and Die Set, 1-853400-0 • Digital Voltmeter (DVM), capable of measuring AC and DC voltage • Agilent E4440A, PSA series high-performance spectrum analyzer • Laptop Computer • 7.2 Linux operating system CUSTOMER SUPPLIED MATERIALS The customer or designated installer must provide the following: • Ethernet Cable, length as required, not to exceed 100 ft. (refer to Section 11.1.1 for cable specifications) • RF coaxial cable (directional or remotely mounted antenna), i.e. LMR-400 Low loss coaxial cable 29 MM-009804-001 7.3 • Pole mounting straps, i.e. Band-It® bands and buckles • Power source (110 VAC 50/60 Hz or 24 VDC) • Ethernet connection to network BEFORE BEGINNING THE INSTALLATION Before beginning the installation, collect information from the Site Deployment Order (SDO) specific to the site access such as: • Permission to access the site • Important contact names and telephone numbers • Location of and directions to the site • Keys and/or lock combinations to access the site and equipment shelter (if any), or points of contact to obtain them • Site entry alarm system pass-codes and/or disable keys • Information about work practices needed to work safely at the site Other important information that may or may not be included on the SDO includes: 7.4 • Type of mounting—metal pole, wooden pole, tower base, exterior wall, etc. • Drawing or description of each site showing how the equipment is to be installed • Applicable inspections completed (pole installation, electrical, local build code, etc.) MOUNTING THE BASE STATION As shown in Figure 7-1, pole-mounting brackets can be installed onto the mounting surface of the base station so it to be mounted (a) horizontally, for instance, on the arm of a light post, or on a vertical (b) post. In both cases, two metal straps (not included) are inserted into slots on the brackets and tightened to the pole using industry strapping equipment. It is important to mount the base station so that its fins are positioned vertically, as shown in Figure 7-1 (a) and (b). This gives the base station the best thermal performance, allowing air to move naturally through the fins Mounting the base station with the fins vertically also allows the RF antenna port to be in the best position for mounting the omni-directional antenna, as shown in Figure 7-1. 30 MM-009804-001 a. Horizontal Mounting b. Vertical Mounting Figure 7-1: Mounting the VIDAMAX Base Station on Horizontal or Vertical Poles 7.4.1 Attaching the Mounting Bracket 1. Orient the brackets so when the base station is mounted on a pole, the fins are vertical. This position provides the best thermal convection (vertical fins) and shields the multiple connectors from rain. 2. Attach mounting brackets to base station using the flat washer, lock washer, and hex head bolt included with the brackets. (Ensure lock washer is closest to the bolt’s head.) Figure 7-2: Brackets attached to the VIDAMAX Base Station (vertical pole mounting) 31 MM-009804-001 3. The preferable mounting scheme is to have omni-directional antenna pointing straight up. 7.4.2 Attaching the Base Station to a Pole Strap the base station to pole using Band-It bands and buckles (not supplied). Follow the manufacturer’s guidelines for proper equipment and techniques. 7.5 POWER CABLES Power is supplied to the base station through a 3-pin connector. Both AC and DC base stations use the same power connector, although they require different cables, available for purchase through M/A-COM. The mating connector is Conxall Multi-Con-X® 3-pin connector #4180-3SG-3xx). 7.5.1 AC Power The AC powered VIDAMAX Base Station requires 110 VAC, 50-60 Hz power applied to the following contacts. Connection 7.5.2 Pin Wire Color Ground Green Neutral White/Grey Hot Black VIDAMAX Base Station Connector DC Power A DC powered VIDAMAX requires 24 ±3 VDC applied to the following contacts: 7.6 Connection Pin Wire Color +24 VDC (PWR+) Red Return (PWR-) Black VIDAMAX Base Station Connector GROUNDING STUDS Mounting studs for grounding the base station are located on two sides of the base station. For safety purposes, earth ground and lightning protection electrical connections should be made at either location. 32 MM-009804-001 7.7 NETWORK/DATA CONNECTION The AC version of the base station connects to the network using standard Ethernet RJ-45 protocol. The DC hardened version connects to the network through a standard LC multimode fiber optic connector. The proper connection in both cases is on the port that does not have the dust cap installed. Recommended Ethernet mating connectors: For AC powered VIDAMAX base station: • Tyco/Electronics, Industrial Circular Ethernet Connector Part number: 1738607-2 For DC powered VIDAMAX base station: • Tyco/Electronics, LC multimode fiber optic connector Part number: 1828618-1 All connections are weatherproof, and the service port has a dust cap which is normally installed to provide the sealing. Sealing of all other ports on the base station is provided through mandatory usage connections. 7.8 ANTENNA CONNECTIONS The omni-directional antenna should be mounted vertically directly onto the antenna port. There is also a mounting feature on the base station to support the mounting a directional antenna. 7.8.1 Installing an omni-directional antenna The omni-directional antenna can be mounted directly to the base station using the following procedure: 1. Connect an N-type male to male RF adapter (not included) to the omni-directional antenna. Hand tighten the connector. Recommend using Amphenol 82-100 or RF Industries RFN-1014-1. 2. For the AC version of the base station, if external lightning protection is required, connect the optional lightning suppressor to the antenna assembly as shown in Figure 7-3. Recommend using M/A-COM # PT-009560. 3. Connect the completed antenna assembly to the base station antenna connector. 33 MM-009804-001 Figure 7-3: VIDAMAX Base Station Antenna with External Lightning Protection 7.8.2 Installing a Directional Antenna The directional antenna (weight less than 5 lb and size less than 350x350 mm^2) can be mounted on the base station using the universal mounting bracket. This mounting bracket is located on the antenna mounting face (cover) of the base station. The universal mounting bracket can then be adjusted to point the beam of the antenna in the direction needed for network connectivity. An antenna weighing more than 5 lb cannot be mounted directly on the base station. A separated mounting bracket is required to mount the antenna directly on the pole while an antenna feeder cable connects the base station to the antenna. A low loss RF cable (not included) is needed to connect between the base station antenna connector and the Directional Antenna. To mount the directional antenna to the base station: 1. Using the four bolts, lock washers and flat washers included in the optional antenna mounting kit, attach the universal antenna mounting bracket to the base station as shown in Figure 7-4. 2. Attach the antenna panel bracket assembly to the antenna panel. 3. Attach the two bracket assemblies together with the universal knuckle. 34 MM-009804-001 4. Attach the short RF cable between the antenna and the base station antenna port. Recommend using < 5 ft. long LMR-400 Low loss coaxial cable with field installable N Type Male connectors, M/A-COM # MAMROS0095. Figure 7-4: Mounting a Directional Antenna to the VIDAMAX Base Station 7.9 GPS Antenna The Base Station performs time synchronization through GPS. An external GPS antenna connection is required. Various antennas are available in the marketplace. One offered by M/A-COM can be mounted directly onto the base station, or alternatively attached to the pole. 7.9.1 Installing Optional GPS Antenna To connect GPS cable to base station: Connect the SMA-type plug of the GPS antenna cable to the SMA receptacle on the base station. Route the cable to the GPS antenna location. This will be a temporary connection until the installation is complete. To install the GPS Antenna: The GPS antenna kit (M/A-COM # MAMROS0023) includes the GPS antenna (part number ANPC185B-Y-180-SM) and various mounts. Based on how the base station is physically positioned, the mounting location that is uppermost is where the antenna can be mounted in order to have best access to the satellites in the sky. Connection to the antenna port is made through the SMA female connector on the base station. Optionally, for lightning protection, a protection device can be externally installed. After installing the antenna, dress and secure the cable. 35 MM-009804-001 7.10 RADIO CHASSIS AND CABLING 7.10.1 Attaching Base Station Cables To connect power to Base Station 1.

Modify the “Setup.txt” file with the IP address of the new base station. 38 MM-009804-001 TROUBLESHOOTING AND SERVICING 9.1 TUNING AND CALIBRATION PROCEDURE Every VIDAMAX Base Station is fully calibrated for frequency and power before shipment to ensure compliance with FCC requirements. No further tuning is required by the customer or installer during the installation process. 9.1.1 Transmit Frequency Accuracy Calibration The accurate frequency setting is a key parameter for VIDAMAX Base Station. Base station frequency accuracy is guaranteed by a Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO) with 1.5 ppm frequency drift over full temperature range. The factory calibration procedures calibrate the default VCTCXO setting to minimize the frequency error. This minimizes the frequency variation from base station to base station. The base station will automatically use default value after each reboot. 9.1.2 Transmit Power Level Calibration The power level calibration is performed at CH1, CH5, CH10 (lowest, middle, and highest) to ensure the over-band performance. An Agilent PSA E4440A under spectrum emission mask mode is used to perform the calibration. A standard baseband OFDM QPSK 3/4 Signal (Downlink Burst, 50% duty, 10 msec. frame) is used for the calibration. The on board 30 dB/ 1 dB step attenuator is used to adjust power level. The cable loss (radio antenna port to PSA input) is calibrated out so the PSA can measure channel power at the antenna port. After the TX power level calibration step, the FCC emission mask is used to check TX spectrum at CH1, CH5 and CH10 to ensure the compliance. After calibration, the base station uses the calibrated TX power as a default value to initialize the radio. 39 MM-009804-001 10 40 RADIO CHASSIS MM-009804-001 11 CABLE FABRICATION 11.1 ETHERNET CABLE PLUG KIT For the AC version of the base station, the Ethernet cable connected to the base station uses a RJ-45 connector protected by an Industrial Circular Ethernet plug assembly that protects the RJ-45 connector from the elements. The Stranded Wire Plug Kit (Tyco Electronics # 1738607-2), shown in Figure 11-1, consists of an 8-position Category 5e RJ-45 plug, load bar, and plug assembly. The load bar is used to hold the cable wires for insertion into the RJ-45 plug. The RJ-45 plug must be terminated and then installed into the plug assembly. The RJ-45 plug is held in the plug assembly by the locking tab. The cable fitting holds the RJ-45 plug in the plug assembly and seals the plug at the cable end. When engaged, the connectors are held together by a locking mechanism (coupling ring and bayonet lock), which prevents accidental disconnection. The engaged connectors are sealed by the interfacial seal. Figure 11-1: Tyco/Electronics Industrial Circular Ethernet Connector Plug Kit (1738607-2) 11.1.1 Tools Required • Modular Plug Hand Tool, 3-231652-0 (Tyco/Electronics-AMP) Includes; Hand Tool, 2-231652-0 and Die Set, 1-853400-0 41 MM-009804-001 11.1.2 Cable Selection The RJ-45 plug will accept Category 5e, 100–ohm unshielded round cable with the following specifications: • Cable type: 8–conductor • Conductor size: 24 AWG • Conductor type: 7–strand copper • Conductor insulation diameter: 0.039 in. (0.99 cm) maximum • Cable jacket diameter range: RJ-45 plug accepts: 0.190 through 0.220 in. (4.83 through 5.59 cm) OD (single jacket) Cable fitting accepts: 0.18 through 0.31 in. (4.6 through 7.9 cm) OD (double jacket) 11.1.3 Cable Preparation Prepare the cable using the following procedure: CAUTION Reasonable care must be taken not to scrape or nick any part of the cable during the stripping operation. 1. Slide the plug assembly (cable fitting end first) onto the cable. See Figure 11-2, Detail A. 2. Proper strip length is necessary to insert the conductors into the contact slots. The recommended strip length is given in Figure 11-2, Detail B. 42 MM-009804-001 Insulation of individual conductors must not be cut or removed. This could result in shorted or open connections. Figure 11-2: Cable Preparation 3. Conductor pairs must be oriented side–by–side in the order shown in Figure 11-3, Detail A. The end of the cable jacket must be flattened so that the conductor pairs lay side–by–side. 4. Properly sequenced conductor pairs should extend into the cable jacket to the dimension given in Figure 11-3, Detail B, creating an oblong shape. 5. The conductor tips must be trimmed evenly to the dimension shown in Figure 11-3, Detail C. Proper orientation of conductors must be maintained. 6. The conductor pairs must be untwisted and arranged according to EIA/TIA T568A or T568B (defined in Figure 11-3, Detail D). IT IS CRITICAL that the pairs are NOT untwisted inside the cable jacket. When arranging conductor pairs, IT IS IMPORTANT that Conductor 6 be crossed over Conductors 4 and 5 as shown in Figure 11-3, Detail C. 43 MM-009804-001 Figure 11-3: Cable Preparation Continued 44 MM-009804-001 11.1.4 Termination Terminate the RJ-45 plug to the cable end using the following procedure: 1. The conductors (maintaining arrangement) must be inserted into the load bar (oriented so that the cable notch will align with the contacts) until the cable jacket rests against the cable notch. The conductor twist must not enter the front of the load bar. The conductors must be trimmed evenly and square with the front edge of the load bar to the dimension given in Figure 11-4, Detail A. Figure 11-4: Termination Requirements 45 MM-009804-001 2. The conductors must be retracted from the load bar so that the conductors protrude from the end of the load bar to the dimension given in Figure 11-4, Detail B. The top of the load bar must not be deformed. If the load bar is deformed, the conductor twist entered the front of the load bar 3. The load bar (oriented so that the cable notch is aligned with the contacts) must be inserted into the RJ-45 plug until it butts against the mating feature of the RJ-45 plug, and the conductors are bottomed on the wire circuits. The cable jacket must be against the cable notch after the load bar is fully seated. The conductors must not be exposed between the cable jacket and cable notch. The ends of the conductors must be clearly visible through the front of the RJ-45 plug. See Figure 11-4, Detail C. If the conductors do not bottom on the wire circuits, they must be re-trimmed (after removing the load bar/cable assembly from the RJ-45 plug), and re-inserted into the RJ-45 plug. If the conductors are too short, the cable must be re-stripped. 4. The RJ-45 plug must be terminated to the cable according to the instructions included with the tooling. 11.1.5 Assembly Assemble the RJ-45 connector into the plug assembly using the following procedures: 1. Align the locking tab of the RJ-45 plug with the wide slot at the front (end opposite the cable fitting) of the plug assembly. See Figure 11-5, Detail A. 2. Depress the locking tab, and insert the RJ-45 plug into the plug assembly. Gently pull the cable until the RJ-45 plug is fully seated. There should be approximately 12.7 mm [.50 in.] of the RJ-45 plug protruding from the front of the plug assembly. See Figure 11-5, Detail B. CAUTION To avoid damage to the connection, the cable must be pulled GENTLY when seating the RJ-45 plug. 3. While holding the RJ-45 plug in position, rotate the cable fitting as shown in Figure 11-5, Detail B until tightened to a torque of 1.13 N–m [10 lbf–in.]. The given torque must be met in order for the cable fitting to seal the plug at the cable end. 46 MM-009804-001 Figure 11-5: Assembly Detail 47 M/A-COM Wireless Systems 221 Jefferson Ridge Parkway Lynchburg, Virginia 24501 (Outside USA, 434-385-2400) Toll Free 800-528-7711 www.macom-wireless.com Printed in U.S.A.
