Wait for about 15 seconds for the modem to register with the Iridium satellite network.
Note
: The A3LA-RM is basically a “black box” with four LED status indicators. This can
pose great difficulties for first-time users who are not familiar with satellite modems.
For application developers, NAL Research recommends using a DPL handset DPLS0401-X
and a data kit HRC-24-8R in combination with the A3LA-RM. This setup can be a useful
diagnostic tool, allowing the modem status to be displayed on the LCD of the handset as
well as using the handset to place a voice call. The red power button on the DPL handset
can be used to power reset the A3LA-RM.

Use any terminal emulator software and AT commands to communicate with the
modem.
However, the A3LA-RM is shipped with a CD with a terminal emulator software package
called SatTerm. NAL Research recommends using SatTerm with the A3LA-RM because it
provides a complete reference manual for all AT commands through user-selected
buttons for quick and easy access.
