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.
STEP 10:
Use any terminal emulator software and AT commands to communicate with the modem. However, the
A3LA-XM is shipped with a CD with a terminal emulator software package called SatTerm. NAL Research
recommends the use of SatTerm with the A3LA-XM since it provides a complete reference manual for all AT
commands through user selected buttons for quick and easy access.
STEP 11:
Check the followings if the A3LA-XM does not respond to AT commands:
1.
Correct data interface is selected (serial or USB)
2.
Correct input voltage (4VDC 32VDC)
Check the followings if a connection cannot be made:
3.
Antenna has a full view of the sky
4.
The PIN number has been removed from the SIM chip
5.
Power source provides enough current
STEP 12:
Check the followings if using the DPL handset:
1.
LCD screen on the DPL handset is ON with the word “Iridium” written across the LCD screen. If
not, check for appropriate power input.
2.
The <Enter PIN> message is not displayed on the LCD. If the <Enter PIN> message appears on
the LCD, enter the appropriate PIN number (the default PIN is 1111). The handset can be used
to remove the PIN permanently.
3.
Displayed satellite signal strength on the LCD must be at least 3 bars. Re-arrange/re-located
the Iridium antenna if the signal strength remains at 3 bars or below.
