6. Getting Started
There are only a few simple steps that you need to follow before using your UD-731:
Install the USB driver onto your laptop using the included CD-ROM .
Plug the GPS receiver into your laptop’s USB port.
NOTE: From within your mapping or navigation software (including the supplied GPS
Information utility), you will need to manually configure the COM port that was
assigned to the UD-731 GPS receiver so that proper communication between the
GPS receiver and a mapping program can occur. Most software requires that you
manually configure the COM port setting for any GPS device being used.
1. You must change the default baud rate setting of your mapping software‘s Baud
Rate to 4800, if this is not set then the GPS data cannot be received.
2. Set Baud Rate 4800, Data Bit: 8, Parity: None, Stop Bit: 1, Flow Control: None
6.1 LED Status

GPSView is multipurpose GPS utility. Please note that GPSView uses specific NMEA
sentences to display data graphically. For more information on NMEA, please see the
appendix 1. GPSView is a general purpose utility for monitoring the output of a GPS
receiver. Using the NMEA data from the GPS receiver, GPSView will display various
statuses for evaluating GPS which including latitude, longitude, altitude, speed, azimuth,
fix mode and TTFF time. And also can be used to upgrade UniTraQ flash version GPS
receiver.
