9522B & COM9522B Iridium Data Modem there are no obstructions to the antennas when installing. You may need to reposition or elevate your antenna to obtain the best reception. The Signal Quality AT command can be used to confirm signal strength during the installation/repositioning of the antenna. This will require the use of a laptop connected to the COM9522B interface and a terminal emulator.
Appendix A. Sample Data Transfer Calculations NOTEThe calculations below are based upon maximum theoretical throughputs. Real world transmission times for the Iridium Satellite Network have proven to be as much as twice as slow. When transmitting the data back from the station, the power consumption of the modem must be taken into account in order to avoid excessive discharge of the battery power supply.
Appendix A. Sample Data Transfer Calculations Power Calculation NOTEWhen configuring a power supply (i.e. solar panel and battery) for a remote station it is essential to design with the worst case scenario in mind. This will help to ensure that the station will perform as expected. The power calculation for data transfer can be carried out now that the transfer time is known.
Appendix B. Hardware Installation The hardware shown in this Appendix consists only of hardware listed in Table 1. Although it may be possible to use other hardware, it will not be addressed in this Appendix. WARNINGDo not connect power to either modem until installation is complete, as damage to the equipment may occur. B.1 SIM Card Installation These installation steps apply to both the Base and Remote modems. Be sure that the correct card is installed in the proper modem.
Appendix B. Hardware Installation Installed SIM Card Card Notch Figure 24. Installed SIM Card B.2 Antenna Installation These instructions apply to both the Base and Remote stations. This installation does not have to precede the modem installation. It should be conducted in the most convenient and logical order. The installation of the antenna and cable should begin with securing the Nu-rail to the threaded pipe supplied, and then feed the antenna cable through the threaded pipe (Figure 25).
Appendix B. Hardware Installation Figure 26. Antenna and Cable Connected Figure 27. Antenna Attached to Mount With the antenna attached to the pipe it is now possible to mount the unit to the structure to be used. As shown in Figure 28 the Nu-rail is mounted to a crossarm Secure the cable at the antenna, providing a dew loop, and secure the remaining cable to the mounting structure. Figure 28.
Appendix B. Hardware Installation B.3 9522B Modem Installation The Base station installation should be conducted before proceeding to the field to conduct the Remote station installation. With the Base station installed first, it will provide the opportunity to test the communications from the Base station before going to, and/or while still in the field. If there is a malfunction, you may be able to address the problem without having to return to the Remote station.
Appendix C. Unlocking a SIM Card There are two methods to unlock a SIM Card, and the equipment you have available will dictate which method is used. C.1 Handset Method To unlock the Iridium SIM card permanently using the Iridium Handset follow these instructions. Install the SIM card, attach the antenna, and 9522B interface. Attach the handset as required. Apply power to the modem. The handset will request the PIN number before proceeding.
Appendix C. Unlocking a SIM Card The modem should response with an “OK” which means the PIN code has been accepted. This explanation assumes that the default code of “1111” is being used. If you get an “ERROR” reply, be sure that the command was entered as shown. If you continue to get an error response, contact the SIM Card provider to determine if a different code is required. The next step is to enter the command to deactivate the PIN code requirement.
