The Iridium Satellite System used with Campbell Scientific consists of the modem, data/power kit (COM9522B), data cables, antenna and power supply. The base and remote stations utilize the same modem type, which both require a change to their configuration.
The recommended connection of the remote modem for all dataloggers is via the RS232, however, the CSI/O port can also be used with the SC932A interface. Power/Data kits are required to connect the modem to the datalogger or computer and an appropriate power source. For remote applications where AC power is not available it is recommended to operate the modem on a schedule to avoid discharging the battery power supply.
The antenna used for both Iridium modems is the SAF5350A mast mount antenna. For best signal reception the antenna should be mounted so that it has an unobstructed view of the sky and horizon. Reception quality changes as satellites move overhead so it is critical that the view be clear.
