6.1.4 RS-232 NMEA Device
With Serial Port Connector
When using a NMEA device with Serial Port connection, a USB to Serial Adapter
(PL-2303HX) is required to connect the device to the Optimizer.
The Optimizer will broadcast the GPS signal both over Ethernet and WiFi, so you
can connect your computer either way in order to establish a successful
connection with your destination software.
CAUTION: The PL-2303HX is the only USB to Serial Adapter that is
compatible with the Optimizer.
NOTE: If your satellite device requires a USB connection to the Optimizer (for example, an
Iridium 9555) you can use a 2-port USB hub (either 1.0 or 2.0) plugged into the Optimizer's
USB port to accommodate two USB devices.
