3. Iridium SIM card & Modem Setup
3.1 Iridium SIM Card Use
Please note that the new SIM cards that come with the Iridium modems may need to
be unlocked. The SIM cards can be activated through an Iridium air time provider.
If you require that the SIM card be unlocked please see Appendix C. This should be
done before going to the field.
3.2 Setup of Iridium Modems
Once the SIM cards are unlocked (Appendix C) it is necessary to set up the base and
remote modems using a terminal emulation program such as ProComm,
Hyperterminal or the terminal screen of the `unknown’ device in Campbell Scientific
device configuration program. The following examples are taken using
Hyperterminal.
3.2.1 Step 1: Hardware Connections
Connect the Iridium Satellite Modem to the COM9522B and connect a serial cable
from the COM9522B to a COM Port on your computer. Connect the COM9522B to
the power supply. Be sure to connect the Yellow power control wire to +12V, so that
the COM9522B will switch on power for the 9522B.
