7.9.
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 t
he satphone’s USB
- Mini/Micro USB cable. (As of this writing, supported
handheld satphones include Iridium 9575 Extreme and Inmarsat IsatPhonePro.)
CAUTION: IsatPhone 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.
A USB connected GPS or NMEA device.
A serial port connected GPS or NMEA device.
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.
To repeat GPS data, a separate GPS device must be connected.
7.9.1. GPS/NMEA Repeater Equipment Setup
A physical connection is required from the source (satellite terminal or satellite phone that
transmits GPS coordinates, or another GPS/NMEA device) to the Optimizer.
