Remote Modem Configuration As a matter of system redundancy, it is recommended that the following programming be used as part of your datalogger program. If this programming is not used, it is possible that the remote modem may lose its configuration. If this occurs, remote communication will no longer be available.
9522B Iridium Satellite Modem and COM9522B Interface Modem 6.1 Program Example 1 In example 1, the station is a solar powered site where power management is a concern. Modem power is controlled by the COM9522B via control port 1. During this time, the modem is sent its configuration via the RS-232 port and the remainder of the time is used for actual communications. The modem is powered up twice per day for 15 minutes each time.
9522B Iridium Satellite Modem and COM9522B Interface Modem 6.2 Program Example 2 In example 2, the station is a solar powered site where power management is a concern. Modem power is controlled by the COM9522B via control port 1. During this time, the modem is sent its configuration via the CS I/O port and the remainder of the time is used for actual communications. For details on programming for the CR10X, contact Campbell Scientific.
9522B Iridium Satellite Modem and COM9522B Interface Modem 7. Troubleshooting Tools and Tips Problem: I have intermittent successful connections between the remote and base station modem. The signal strength is weak and the data transfer speeds are slow. Solution: The antenna may not have a complete 180° view of the sky. Some objects and debris such as snow and trees can interfere with communications. Make sure there are no obstructions to the antennas when installing.

Appendix A. Sample Data Transfer Calculations NOTE The 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 NOTE When configuring a power supply (that is, 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 1-1. Although it may be possible to use other hardware, it will not be addressed in this appendix. WARNING Do 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 the correct card is installed in the proper modem.
Appendix B. Hardware Installation Installed SIM Card Card Notch FIGURE B-3. 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 30741 antenna and cable should begin by feeding the antenna cable through the nut, then spacer, and finally antenna mount (FIGURE B-4).
Appendix B. Hardware Installation FIGURE B-4. Antenna, Mount, and Cable Thread the antenna onto the 3/4 inch supplied nut, being sure not to cross the threads (FIGURE B-5). FIGURE B-5.
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. 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 next step is to enter the PIN code for the SIM card. AT+CPIN=”1111” The modem should respond 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.
