CHAPTER 1 IMPORTANT Prior to operation of this equipment, proper authorization and/or licensing by relevant Authorities is required. IMPORTANT Prior to transmission of radiated signals authorization from the satellite operator is required IMPORTANT All safety precautions should be read and understood prior to deploying the Norsat NewsLink. W ARNING FCC INFORMATION FOR UNINTENTIONAL RADIATOR PORTIONS AS PER FCC 15.19, 15.21 AND 15.
Page 2 W ARNING FCC FREQUENCY COORDINATION AS PER FCC 25.203(C), 25.251 AND 101.103 To satisfy FCC frequency coordination requirements, the user must ensure that they co-ordinate proposed frequency and power usage with other terrestrial and satellite users prior to transmission. W ARNING MICROWAVE RADIATION: HAZARDS CAUSED BY ELECTROMAGNETIC FIELDS When in operation, i.e., power on, the area directly in front of the antenna reflector must be considered an Area of Restricted Occupancy.
CHAPTER 2 Norsat ODU Overview The Norsat Outdoor Unit (ODU) is a portable antenna/RF assembly, that when coupled with an appropriate IDU, allows transmission of signals to a satellite and reception of signals from the satellite. Its design allows it to be carried by two people, with an in field deployment and setup time by a non-experts of less than 15 minutes.

Page 5 The Norsat ODU is enclosed in three cases; the RF Unit case (Model 3300-RF), Antenna Unit case (Model 3200-ANT), and Accessories case(Model 3200-AC). Once the team is on location, the antenna is removed from the case and assembled. After the antenna is assembled, it is connected to an appropriate IDU. The Norsat ODU is now ready for operation. The antenna must be aligned to the proper elevation, azimuth and polarization for the desired satellite transponder.

Page 10 FIGURE 3 ODU Deployed ODU Interfaces The Norsat ODU has the following interfaces: Transmit IF (Tx) NOTE Norsat ODU • Transmit IF • Receive IF • Transmit Monitor IF • SSPA Control and Monitor • AC Power The Transmit IF (Tx) connector is a 50 ohm N-type female connector, which is colour coded red. The signals supplied on this interface are: Transmit IF (950 and 1450 MHz): the signal to be upconverted, amplified and transmitted to the satellite.
Page 11 Receive IF (Rx) NOTE The Receive IF (Rx) connector is a 50 ohm N-type female connector, which is colour coded green. The signals supplied on this interface are: Receive IF: the received signal amplified and downconverted by the LNB. 24 VDC: supplied to the LNB. This interface does not supply a 10 MHz signal. This cable is a 50 ohm cable rather than the usual 75 ohm cable for receive systems. The LNB has a 75 ohm connection, however, the impedance is changed in the Interface/Indicator unit.
Page 12 Antenna The antenna consists of the parabolic reflector, feed horn, OMT, flex waveguides, feed support with built in rigid waveguide and filters and mechanical support structure. The mechanical support structure positions and points the antenna reflector in order to aim the antenna beam at the required satellite. Transceiver The Transceiver consists of block upconverter, a SSPA and a lownoise block (LNB) downconverter.
Page 13 degree. The compass is mounted on the base of the antenna in order to accurately indicate the azimuth of the antenna beam. The compass is powered by 12 V supplied from the Interface Indicator Unit. It is connected to the Interface Indicator unit by a flying lead with a multipin connector. As with all fluxgate compasses, best performance occurs when the compass is level and there is no ferrous metal objects nearby.
Page 14 Ku-L Block Downconverter NOTE Norsat ODU Converts the Ku-band transmit signal, received from the SSPA monitor port, to transmit monitoring L-band (950-1450 MHz) signal. The Ku-L Block Downcinverter is non-inverting. For example a transmit monitor signal at 14.
CHAPTER 4 W ARNING ! Norsat MODEL 3300 ODU Deployment FCC RF EXPOSURE INFORMATION To satisfy FCC RF exposure requirements for mobile transmitting devices, a separation distance of 7.5 meters or more should be maintained between the antenna of this device and persons during device operation. To ensure compliance, operations at closer than this distance is not recommended. W ARNING FCC Frequency Coordination as Per FCC 25.203c and 101.

Page 32 ODU and IDU Interconnections The following steps describe the procedure for interconnecting the ODU and IDU units. CAUTION Interfacility Link NOTE All connections/disconnections should be made while IDU and ODU power is off. The IDU and ODU unit are connected via a multi-cable assembly called the interfacility link (IFL). . Norsat offers either a 10m IFL or a 30m IFL.
Page 33 CAUTION All co-axial cables in the IFL carry 24 V DC. The Monitor and Control cable contains the following control signals: • SSPA Mute • Temperature Sensor Reading • SSPA Power Detector Reading • SSPA Fan Alarm • Receive Signal Strength The SSPA Power and the Monitor and Control cables are terminated in a common multi-pin connector. The IDU side uses a male connector and the ODU side uses a female connector. The cable ends are labeled Antenna and Baseband accordingly.

CHAPTER 9 Troubleshooting This chapter provides troubleshooting scenarios, along with suggested solutions. 1. Check all cable connections to ensure they are secure and correctly hooked up. General 2. Check your external power source to ensure the source is stable. DC Power Indication Listen for the fans on the SSPA. If the fans are running there is DC power applied to the unit. Transmission must be enabled by the IDU.
Page 44 Cable By-pass Procedures Each of the three co-axial cables in the IFL are of identical cable types, 50 ohm Belden 9907 with N(m) connectors, and can be substituted for each other. For alignment of the antenna, the GREEN marked Receive IF coaxial cable must be correctly connected as described earlier. However, the RED and BLUE marked coaxial cables need not be attached. For transmission, the RED marked Transmit IF coaxial cable must be correctly connected as described in earlier.
Appendix A Compass Calibration To calibrate the compass, the Antenna must be rotated slowly for one complete turn; two turns on initial calibration. NOTE To avoid tangling the IFL cable, before beginning compass calibration, wind the IFL cable around the Antenna as many times as the Antenna will be rotated during the calibration procedure. The following steps describe the calibration procedure: 1. Set-up the ODU unit. 2. Connect the ODU unit to the IDU unit. 3. Power up the IDU unit. 4.
Page 46 of the calibration: i. A: indicates the quality of the calibration, with 9 being highest, and 7 being the minimum acceptable level. ii. B: indicates quality of magnetic location, with 9 being the highest and three or lower being very poor. iii. C: indicates the number of calibrations completed. 10. To exit calibration mode, depress the MODE button briefly. Switching the LNB The Norsat NewsLink comes with a set of three LNBs for worldwide coverage.
