Introduction
This manual shows, how to connect the GNS601 Starter Kit to a PC in order to verify GNS601
module performance and test supported features.
For technical specification, please refer to the GNS601 datasheet.
GNS601 is one of the smallest GPS receiver module based on the MT3339 single chip solutions,
available with a finely tuned, high-sensitivity patch ceramic antenna. It has a very compact and
easy to integrate design with the ultimate tracking performance.
The specific documents and reference layout in Gerber-file format are available for download at
http://www.forum.gns-gmbh.com/ .
Connected to a PC, all GPS data (NMEA) is routed to the miniUSB port. A powerful NMEA command
interface is available to modify GPS receiver configuration for customer requirements. For receiver
configuration programming via NMEA command interface, please refer to the
NMEAcommandInterface manual.
All documents which are highlighted in bold letters, are available for download at the GNS forum:

3.1 Getting started ….
1. Insert the included CD into your CD Rom Drive. Change to \Driver folder.
2. Copy the two files from the \Driver folder to a PC folder of your choice.
3. GNS601 Starter Kit will be connected to the PC via a virtual COM-Port with USB.
This conversion is performed by an onboard chip.
Do not connect the USB cable now!
First, please install the FTDI VCP (Virtual Com Port) driver by invoking USB-Driver-
CDM20600.exe.
A DOS window will open and close again after a few seconds when finished.
4. The VCP USB driver is now ready to use.
5. Connect the Starter Kit to your PC by using the USB- to miniUSB cable. This will power up
the Starter Kit (shown by the blinking green LED fix indicator) and establish the active state.
6. You should see a hint on the right lower corner of your PC screen, that a new hardware has
been found and is ready to use.
7. Assign the virtual COM-Port number by executing “Windows Start Button” and select “Control
panel”.

10. Select “Ports (COM&LPT)” and notice the “USB Serial Port” number.
11. Start your preferred NMEA-Viewer software (for example: Visual GPS, free NMEA-Viewer,
Link: http://www.visualgps.net/VisualGPS/default.htm ) to visualize the NMEA-protocol data
and connect COM-Port using the default data rate of the GNS 601 module of “9600Baud”.
