Using the GNSS Receiver 5
GNSS Connector software
You can install the GNSS Connector software on a GeoExplorer 6000 series handheld.
Use the software to specify how the integrated GNSS receiver communicates with
equipment that is connected to one of the handheld’s external communications ports.
To install the GNSS Connector software, go to www.trimble.com/support.shtml. Click
GNSS Connector and then click Downloads. Follow the instructions in the Installation
wizard.
Other GNSS field applications
If you have purchased and activated the NMEA Output option, you can also use the
GeoExplorer 6000 series handheld with any GNSS field software that accepts NMEA
messages.
Configuring the GNSS field software to connect to the
receiver
The first time you use GNSS field software on the handheld, you may need to specify
which GNSS COM port to connect to.
GNSS COM ports
The integrated GNSS receiver has three COM ports for communicating with software
on the handheld and with external devices. Two ports are for outputting GNSS data,
and one port is for receiving real-time corrections into the receiver.
To use GNSS, open the appropriate GNSS COM port. The type of communication used
for each port is described below:
Note – NMEA messages can only be output if you have purchased and activated the
NMEA Output option.
Port Function Description
COM2 NMEA Outputs NMEA-0183 messages. NMEA is a standard GNSS
communication protocol used by many GNSS applications.
The handheld outputs the following NMEA messages by default: GGA,
GLL, GSA, GSV, RMC, VTG, ZDA. All messages are output at a one-
second interval.
COM3 TSIP Outputs and receives TSIP messages. TSIP (Trimble Standard Interface
Protocol) is used by Trimble GNSS applications, and is also supported
by some other GNSS applications.
COM4 Real-time
corrections
Receives real-time correction messages. If you are using an external
correction source connected to COM1 or a Bluetooth port, the
corrections must be redirected to COM4. For more information, see
Using real-time corrections from an external correction source,
