5.0 GPS/NMEA Repeater
The Optimizer supports USB and RS-232 NMEA devices allowing multiple applications
to share the GPS/NMEA data. If you have a NMEA RS-422 device, adding a RS-422 to
RS-232 converter to your setup may allow the sharing of data.
The Optimizer does not transmit data but can be configured to receive and repeat
GPS/NMEA data from:
•
A broadband satellite terminal with integrated GPS when connected to the
Optimizer via a standard ethernet connection. (As of this writing, supported
terminals include: Iridium Pilot, Inmarsat FBB and Inmarsat BGAN).
•
A handheld satellite phone with integrated GPS when connected to the Optimizer
with the satphone's USB-Mini/Micro USB cable. (As of this writing, supported
handheld satphones include: Iridium 9575 Extreme and Inmarsat IsatPhonePro.)
•
A USB connected GPS or NMEA device.
•
A serial port connected GPS or NMEA device
WARNING: IsatPhonePro users! The phone only transmits GPS coordinates
about every 10 minutes. It is NOT recommended for navigation or any
application that requires real time data.
NOTE: If you are using a satellite phone with a serial port (RS-232) that transmits
GPS data (i.e. some fixed phones and fleet phones), it is NOT compatible with the
Optimizer. In order to repeat GPS data, a separate GPS device must be
connected.
