Using the GNSS Receiver 5
The GNSS Connector software lets you connect the NMEA GNSS COM port to COM1
or Bluetooth ports and configure port settings such as the baud rate for COM1.
Use the GNSS Connector software to output NMEA messages from the integrated
GNSS receiver to another device, such as an external data collector.
Note – If you are using a Bluetooth port, ensure that the Bluetooth radio is on and the
handheld is visible to other devices. Use the GNSS Connector software to configure NMEA
output to Bluetooth - COM9, which is the pre-defined Bluetooth Host Serial Port. For more
information, see Providing Bluetooth services as a host, page 89.
The connections that you create in the GNSS Connector software are active only while
the software is running. Connections created by the GNSS Connector end when you
exit the software.
For more information, go to www.trimble.com/support.shtml and refer to the GNSS
Connector Help. Click GNSS Connector and then click Help.
Configuring NMEA output
You can use the GeoExplorer 6000 series handheld's integrated GNSS receiver with any
GNSS field software that accepts NMEA messages, if you have purchased the NMEA
output option and it has been activated on the handheld.
To configure the NMEA data output settings, use the
GPS Controller software. The software is provided free
from the Trimble website. For more information, see GPS
Controller software, page 62.
To configure NMEA data output:
1. In the GNSS Settings form, set the NMEA Output
field to On.
2. Tap the
Setup button that appears next to the
NMEA Output field. The NMEA Output Settings
appears.
3. Configure the NMEA message output settings.

CAUTION – NMEA standard dictates that a baud rate of 4800bps should be used for
NMEA messages. Depending on the number of satellites being tracked (for example, if
you are tracking GLONASS and GPS satellites) the amount of data being captured at once
may often cause the 4800 bit limit to be exceeded.
Buffers have been added which allow the data to be stored and then sent when it is able
to. This avoids data corruption, but may delay delivery of data, and positions may take as
long as 8 seconds to be sent from the time at which they were originally recorded.
If you need 4800bps output, Trimble suggests that you try to minimise the effect by
reducing the amount of NMEA data being sent, for example, by dropping out NMEA
sentences from the NMEA stream.
4. Tap Done.
