SAFETY SSPB-K20 (SSPBM-K16-CSF) In addition to this section, included by reference are the following pertinent sections of the International Standard IEC-215, ‘Safety requirements for radio transmitting equipment’: Appendix D, ‘GUIDANCE ON ASSESSING THE COMPETENCE OF PERSONNEL FOR DESIGNATION AS SKILLED’ and also Sub-clause 3.1 of the Standard. Appendix E, ‘GUIDANCE ON SAFETY PRECAUTIONS TO BE OBSERVED BY PERSONNEL WORKING ON RADIO TRANSMITTING EQUIPMENT’, also Sub-clauses 3.2, 3.7 and 22.1 of the Standard. To prevent the risk of personal injury or loss related to equipment malfunction Advantech Wireless uses the following symbols for safety related information. For your own safety, please read the information carefully BEFORE operating the equipment. Symbols used in this manual: WARNING! Indicates a hazardous procedure that may result in serious injury or death, if not performed properly. CAUTION! Indicates a dangerous procedure that may result in light-to-severe injury or loss related to equipment malfunction, if proper precautions are not taken. Page 6 SSPB-K20 (SSPBM-K16-CSF) -------------------------------------------- WARNING --------------------------------------------- The operator cannot repair this unit. DO NOT attempt to remove the top cover or disassemble the internal components. Only qualified service technicians should service this unit. There is a risk of damaging the precision components. ----------------------------------------------- WARNING ------------------------------------------ ALWAYS TERMINATE THE OUTPUT WAVEGUIDE OF THE UNIT WITH AN RF LOAD CAPABLE OF DISSIPATING FULL CW RF POWER. SIMILARLY TERMINATE THE RF INPUT PORT TO AVOID THE POSSIBILITY OF THE UNIT BEING DRIVEN BY STRAY LEAKAGE SIGNALS. Incorporate the terminations prior to applying prime power to the unit. This procedure prevents self-oscillation and irradiation from and into the local environment. If an RF source is not connected to the RF input port, the unit may go into a self-induced mode and generate high levels of RF energy. Destruction caused by an excessive load voltage standing wave ratio (VSWR) will void the warranty. ----------------------------------------------- WARNING ------------------------------------------- DO NOT LOOK INTO THE RF OUTPUT PORT OF THE POWERED BLOCK UP-CONVERTER! Handle the powered SSPB with extreme care. Keep in mind that the levels of microwave radiation, which do not induce immediate physical discomfort in most individuals, can be sufficiently high to induce long term effects. The eyes are the most vulnerable parts of the body. The maximum permissible levels of exposure are quite low in comparison to the power levels produced by the equipment built by Advantech Wireless (e.g. less than 10 mW versus 4 to 700 W delivered by the different units). The maximum permissible levels are currently being studied by a number of organizations. In the past the U.S. Safety Code established a dosage rate of 10 mW/cm2. Currently, there is consideration being given to reducing the permissible level to 1 mW/cm2 in the United States, as has been the case for several European countries. Page 7 2. GENERAL INFORMATION SSPB-K20 (SSPBM-K16-CSF) 2.1 INTRODUCTION This manual contains information that describes the installation, operation and maintenance procedures for the 16-Watt Ku-Band hub-mount (outdoor) Solid State Power Block Up-Converter model SSPB-K20 (SSPBM-K16-CSF). Because specialized training is required for some phases of installation and operation, certain parts of this manual are directed only to properly trained personnel. Warnings appear at the appropriate points to caution all users of the potential RF hazards. For a safe and versatile operation, please read the information carefully BEFORE using the equipment. Advantech Wireless has prepared this manual for use as a guide for the proper installation, operation and maintenance of Advantech Wireless equipment and computer programs. The drawings, specifications and information contained herein are property of Advantech Wireless. Any unauthorized use or disclosure of these drawings, specifications and information is prohibited; they shall not be reproduced, copied or used in whole or in part as the basis for manufacturing or sale of the equipment or software programs without the prior written consent of Advantech Wireless. 2.2 DESCRIPTION The SSPB-K20 (SSPBM-K16-CSF) is a 16-Watt Ku-Band hub-mount (outdoors) Solid State Power Block Up-Converter (SSPB). The entire SSPB is self-contained and is intended for mounting on to the antenna hub, see Figure 1: Product Outline at page 11. It incorporates an Interface Assembly, Up-Converter Assembly, High Power Amplifier (HPA) Assembly, Power Supply Assembly and a Main Controller Board. The block diagram of the SSPB is shown in Figure 2: Block Diagram (page 12) and the various connectors are shown in Figure 3: Connectors (page 15). 2.2.1 POWER SUPPLY There is only one power supply assembly in this SSPB. The power supply provides +12 V DC high current and – 9 V DC low current for the SSPB. The power supply is configured for operation from 90 - 264 V AC (autoranging), single phase, 47-63 Hz. The overall power consumption, at the rated RF output power, is 300 watt, typical. Page 8 2.2.2 UP-CONVERTER ASSEMBLY SSPB-K20 (SSPBM-K16-CSF) The RF signal arriving from a modem enters the Up-Converter Assembly through a type ‘N’ connector, see Figure 3: Connectors (page 15). A diplexer within this assembly separates the input signal into a 10 MHz reference signal and the 950 MHz to 1450 MHz L-Band signal. The reference signal is sent to a synthesiser within the Up-Converter Assembly. The L-Band signal enters the high gain Low Noise Amplifier (LNA) and Medium Power Amplifier (MPA) stages that boost the RF power level sufficient for the transmission through the Up-Converter Assembly. Integral to the UP-Converter Assembly is a variable attenuation section that maintains the overall gain of this module constant against changes in temperature (global temperature compensation). A temperature dependent DC voltage is sent from a temperature sensor from within the HPA Assembly through the power conditioner board to the attenuator. The amount of attenuation is varied with the change in the DC voltage. The Up-Converter Assembly converts and amplifies the incoming L-Band carrier signal into a Ku-Band carrier. To achieve this requirement, this assembly contains a synthesiser, a mixer, a multiplier, two LNAs and a band-pass filter, see Figure 2: Block Diagram (page 12). For this application, the Up-Converter requires the L-Band signal, which is sent to the mixer and the 10 MHz reference signal, which is fed into the synthesiser. The synthesiser contains a phase-locked loop local oscillator (PLL LO), which is normally phase-locked with the incoming 10 MHz external reference signal. When functioning correctly, the PLLLO generates a 2.175 GHz signal. The multiplier converts this signal into a 13.050 GHz LO signal. The 13.050 GHz signal and the L-Band signal are fed into a mixer to produce the required Ku-Band signal. The frequency-range provided by the Up-Converter Assembly is from 14.000 GHz to 14.500 GHz. The synthesiser also contains an out of lock protection circuitry that prevents frequency shifts from occurring to the resulting Ku-Band signal. When the oscillator is not phase-locked, a signal is sent to the power conditioner board within the HPA Assembly to shutdown the RF devices. The band-pass filter removes the unwanted harmonic frequencies, allowing the Ku-Band signal to pass through the HPA Assembly. Page 9 SSPB-K20 (SSPBM-K16-CSF) 2.2.3 HPA ASSEMBLY The HPA Assembly amplifies the RF signal from the Up-Converter Assembly to a power level sufficient for transmission. Integral to this module are three HPA stages and a power conditioner board. Other functionality includes internal power conditioning and overtemperature shutdown. 2.2.4 CONTROLLER BOARD All of the controls, input/output communication and the decision-making, with the exception of the critical module-level decision are performed by the micro-controller within the Up-Converter. The Controller Board provides through the System Control interface: • Fault detection and indication • Forward RF power monitoring and indication (optional) • Temperature monitoring and indication • ON/OFF transmit switching • Change in the unit’s address An ALARM will be triggered when the internal temperature of the SSPB exceeds 70°C. The SSPB will continue to operate in this condition. A FAULT signal will be sent to the user if any one of the following occurs: • Phase-locked loop oscillator within the synthesiser is out of lock. • The baseplate temperature exceeds 85 °C • Any of the RF devices fails In case of over-temperature (>85 °C), the SSPB will automatically restart when its internal temperature decreases to 60 °C.

UNPACKING AND INSTALLATION This Section contains instructions for the site preparation, unpacking and the installation of an SSPB. 3.1 INITIAL INSPECTION Inspect the shipping container for damage. If the container or cushioning material is damaged, immediately contact the carrier that delivered the equipment and submit a damage report. Failure to do so could invalidate all future claims. 3.2 UNPACKING Carefully unpack and remove all of the items from the shipping container (inspect the interior of the container for damage). Save all of the packing material until completing a visual inspection. Verify that all of the items listed on the packing list are present. Inspect all of the items for evidence of damage, which might have occurred during the shipment. If damage seems evident, immediately contact the carrier that delivered the equipment and file a claim. Failure to do so could invalidate future claims. Check the unit thoroughly for damaged or loose parts. After completing a visual inspection, proceed to the next step. 3.3 INSTALLATION Installation of the SSPB includes the following four phases: • Mechanical installation • Electrical installation • RF connections • Cooling considerations 3.3.1 MECHANICAL INSTALLATION The SSPB is designed for hub-mount (outdoors) applications. Figure 1 at page 11 shows the overall mechanical dimensions of this SSPB. Page 16 SSPB-K20 (SSPBM-K16-CSF) 3.3.2 ELECTRICAL CONNECTIONS Electrical connections to the SSPB consist of the prime power AC LINE applied to the AC Line Connector (J5). For the connector location, see Figure 3: Connectors at page 15. Perform the electrical connections as follows: • Using the connector provided in the shipping kit (item 5, TABLE 9 at page 33), construct an AC Supply cable with a pin assignment as shown in TABLE 6 at page 15. • Verify that the AC power source is turned OFF. • Connect the SSPB to the AC power source. For the correct input voltage level refer to TABLE 3 at page 14. • Turn the AC power source ON. 3.3.3 RF CONNECTIONS The following three RF connections are provided by the SSPB: • RF input (J1) - Type ‘N’ Female, see Figure 3: Connectors at page 15. The user needs a type ‘N’ male connector for the interface connection. CAUTION! Beware of the destructive pin depth of the mating connector. When installing an RF mating connector with a destructive pin depth into an RF component connector, damage may occur to the RF component connector. A destructive pin depth is a connector having a pin length that is too long in respect to the reference plane of the connector. The centre pins of the connectors used by ADVANTECH AMT™ have a precision tolerance measured in mils (1/1000 inch). The mating connectors of the various suppliers may not be of precision types. Consequently, the centre pins of these devices may not have the proper depth. • RF output (J7) - WR-75 waveguide flange (grooved), see Figure 3: Connectors at page 15. The user needs a WR-75 flat waveguide flange. • Attach the correct RF cable with mating connector to their corresponding connector ports on the SSPB. • Wrap mastic tape (item 8 of TABLE 9 at page 33) around all of the SSPB connectors in order to prevent water/humidity ingress, which may result in damage. • Squeeze the tape tightly, ensuring that both ends of the tape have formed around the connector and the cable. Page 17 3.3.4 COOLING CONSIDERATIONS SSPB-K20 (SSPBM-K16-CSF) The SSPB is forced-air cooled. The cooling fans are configured for 12 V DC operation, supplied by the main power supply of the unit. Depending on environmental conditions, the airflow opening may become obstructed by debris, reducing the efficiency of the cooling system. NOTE: The cooling fans rotation speed is temperature dependent. Inspect the unit periodically to ensure that the grill of the fans intake and all openings on the unit are free of any obstructions. Insufficient air-cooling will significantly impact upon the SSPB longevity. Page 18 4. INTERFACES SSPB-K20 (SSPBM-K16-CSF) 4.1 SYSTEM CONTROL CONNECTOR The System Control interface connector is located at port (RS232 RS485) of the SSPB. This is a 10-pin MS3112E12-10P (male) connector with pin assignments as shown in TABLE 7 below. Both RS-485 and RS-232 serial interfaces are for the serial interface communication link, allowing for the external monitoring and control of the SSPB.

Page 19 SSPB-K20 (SSPBM-K16-CSF) 5. PRE POWER AND CHECKOUT This Section contains the pre-power and checkout procedure for the SSPB model SSPB-K20 (SSPBM-K16-CSF). WARNING! The information presented in this Section is addressed to the technicians who have specific training in, and knowledge of the Microwave Power Transmitters. Inappropriate use of an SSPB may cause serious injury to the operator or damage to the equipment. Do not attempt to operate an SSPB before becoming thoroughly familiar with the contents outlined in this Section. 5.1 PRE-POWER PROCEDURES Before applying prime power to the SSPB, verify that the following conditions are met: • The voltages of the station AC prime power matches those marked on the ID label; it is 110/220 V AC (autoranging), 47-63 Hz, single phase, for these units. • The prime power station is properly grounded. • All connections are tight, no wires are pinched, and no other hardware has loosened while handling the SSPB. • The main power switch on the prime power station is turned OFF. • The RF input and RF output ports are connected to a matched source and a proper load capable to withstand full CW RF power see TABLE 1 at (page 13). • The heatsink is not obstructed. • The cooling fans are not obstructed. CAUTION! Failure to verify these pre-power conditions may damage the SSPB causing it to malfunction. Operating the SSPB before verifying the above conditions may void the warranty. Page 20 6. MAINTENANCE SSPB-K20 (SSPBM-K16-CSF) This Section describes the scheduled maintenance procedure for the SSPB. CAUTION! Improper maintenance of the SSPB may void the warranty. 6.1 PREVENTIVE MAINTENANCE This product requires minimum maintenance, which consists of visual inspection and cleaning. WARNING! Personnel performing maintenance on this system must have the proper training and become thoroughly familiar with the related safety requirements and issues. Read and practice the safety guidelines as described in (Section 1 at page 6). 6.1.1 MECHANICAL PREVENTIVE MAINTENANCE Mechanical preventive maintenance consists of verifying the condition of all mechanical parts with the AC power switched off. Perform the following inspection: 1. With the AC power disconnected or switched off, check that all of the connectors and plugs are seated properly in their mating-connectors and have not been damaged. Replace any damaged connector plugs and reset any that are dislodged. Inspect the electrical wiring for signs of discolored, broken or poor insulation. Repair or replace as required. Check for other defects such as breakage, fungus, deterioration, excess moisture and mounting integrity. 6.1.2 CHECKING THE COOLING FANS The cooling fans are located at the bottom shroud of the SSPB. Verify that the fans are operating smoothly. Any suspect noise may indicate wear and the respective fan will have to be replaced. Check for debris or dust in the fans intake and in all openings on the unit. Any obstruction may reduce the efficiency of the cooling system. The fans should be replaced every two years, in order to ensure the proper cooling of the unit. WARNING: Do not come in contact with any electrical assembly while power is applied.

APPENDIX A: RS-485 SERIAL COMMUNICATION PROTOCOL 11.1 INTRODUCTION This Section describes the RS485 serial interface for interconnection between External Network Management System (NMS) and Advantech Wireless units. This protocol supports 2 and 4 wires RS485 interface 9600.N.8.1. 11.2 FRAME STRUCTURE Each frame starts with the start byte 0x55. After this start byte, each frame consists of 7 bytes. First byte: Master (NMS) to Slave (Advantech Wireless unit): Address of correspondent Advantech Wireless unit (0x01 to 0x0F). Slave to Master: When Advantech Wireless unit sends the response frame to NMS, it left shifts its unit address by 4. For example, the unit with address 0x05 will send 0x50 in the address byte. Second byte: Master to Slave: Command byte. The command codes are described in TABLE 10. Slave to Master: First data or status byte Third, forth, fifth and sixth bytes: Master to Slave: Value of parameter or expansion of command (third byte, if applicable) Slave to Master: Remaining data or status bytes Seventh byte: Check sum, calculated as algebraic sum of bytes 1 to 6. All not used bytes are always set to 0xAA. The format for gain, attenuation, power level and temperature is a 2-bytes hexadecimal value in 0.1 dB, 0.1 dBm, 0.1 °C (signed integer).

APPENDIX B: RS-485 SKYWAN SERIAL COMMUNICATION PROTOCOL For remote operation, the SSPB is equipped with a monitor and control function. The M&C function contains all of the relevant data concerning the control and status signals of the SSPB. This is achieved by using a four-wire RS485 signal. CONSIDERATIONS 12.1 HARDWARE In order to use the RS485 serial communication between a DB-9 serial connector of a PC and the 25-pin MS connector (J3) of the SSPB, or the 15-pin MS connector (J2) of the SSPB, an adaptor RS-485/RS-232 should be used. Follow the wiring described in TABLE 7. 12.2 RS-485 INTERFACE ON 4 WIRES This is a 4-wire full-duplex interface. In order to maintain synchronization, the RS485 receiver will reset if a message is not completed within 50 msec of initiation. 12.3 TRANSMISSION PROTOCOL Baud Rate 9600 bps Data Bits 8 Parity none Stop Bits 1 Minim Response Time 10 msec Maximum Response Time 20 msec If the SSPB does not respond within the maximum response time, the controller should cyclically repeat the command. The SSPB is equipped with a calibrated power sensor for measuring the power delivered to the antenna from the rated output value to the 20-dB back off. This value, in dBm, is available through the M&C RS485 Interface for the monitoring of the power level and the ALC. The reported power accuracy is ± 1.0 dB absolute and ± 0.5 dB relative. Page 39 SSPB-K20 (SSPBM-K16-CSF) 12.3.1 TRANSMISSION INTERFACE A request packet (see TABLE 14) is sent by the IDU and the respective response packet (see TABLE 15) by the SSPB. The IDU is the bus master. The SSPB is only allowed to respond if the first byte of the request packet matches its address and the checksum is consistent. Upon reception of a request packet the SSPB will perform the following consistency checks: 1) Verify that the checksum is consistent. 2) Verify that the packet address corresponds with the SSPB address. 3) Verify that the received command corresponds to a defined command. 4) Verify that, if data is required for the command, its value is valid. If the received packet passes test (1) and test (2) but fails in test (3) or in test (4), a response packet will be returned. Bit #2 of byte #5 will be set to 1 to indicate that an inconsistency was detected in the request packet.
