Safety Tips
1. i.Trek GPS receiver uses Li-Ion battery. If the GPS is exposed to temperature
higher than 60 °C or below -10 °C, it may cause charging capacity to decrease or
permanently damage the battery.
2. Do not use Bluetooth GPS in hospital or airplane. Bluetooth may interfere with
equipment which uses radio frequency.
3. Take out the battery and store it in dry/cool places when you don’t intend to use
GPS receiver for extended period of time.
4. Use only the supplied and approved accessories. Unauthorized accessories,
modifications or attachments could damage the GPS receiver, and may violate
regulations governing radio devices.
5. Do not attempt to open the GPS receiver by yourself. Unauthorized hacking may
damage the unit, and void your warranty.

Configuration
Connection Setting
This is to establish a connection between the computer and GPS receiver. Please make
sure USB cable is connected to your computer.
•The program can auto-detect available com port by using Scan function.
•Or you can go to Windows device manager and note the corresponding virtual
COM port. (Check virtual com port number of GPS data logger)
•Select correct com port. (COM7 used in this example) and set Baud Rate at
115200.
•Click on Connect to establish a connection. GPS status in the SATELLITE
INFORMATION section will start to show when you click on it.
•To stop connection, please click on Disconnect.
Output Period
This is to set NMEA output for the Bluetooth interface in the NAV mode.
•Check the NMEA type -> Choose output period -> Set
•For selecting NMEA data output (RMC, GSV, GSA, GGA are compulsory data, user
are not allowed to DE-SELECT)
•NMEA setting here will only affect the NMEA sentences for navigation usage. This
has nothing to do with logger’s data recording.
•Period (s): For example, GLL (4) stands for GLL sentence update every 4 seconds.

Configuration (cont.)
AutoLog Option
This is to set recording interval in LOG mode.
•Time: Configure log interval between 1~999 sec. For example, “10 Seconds”
means that GPS will record one data every 10 seconds.
•Distance: Configure log interval between 10~9999 meter(s). For example, “10
meters” means that GPS will record one data every 10 meters.
•Speed: Configure log interval between 10~999 km/h.Set speed at the highest
rate. If any log data exceeds this speed, it will be recorded. For example,
“100km/hr” means that GPS will record one data when exceeding 100km/hr. The
number of data count shows the time user exceeds 100km/hr.
•Time / distance/ speed can be mixed in a data log.

Setting up Your Software
Every navigation software has different setup instruction. Please refer to the user manual of
each respective program for detail setup information. Below are some useful tips.
Protocol
The default protocol on i.Trek Z1 GPS receiver is NMEA and majority of the navigation
software also uses NMEA as standard protocol. We recommend keeping this setting at default.
Baud Rate
4800 is the most common baud rate used by navigation software, and we recommend
keeping this value. However, if 4800 does not work, we recommend switching the baud rate
to 11500.
Com Port
Com port is assigned by Bluetooth Manager automatically. If several choices are available,
please make sure the software uses the com port which has been assigned to serial port (out
bound).
Connection
Some software offer several choices for GPS connection. Please make sure connection method
is set to Bluetooth.
FAQ and Trouble Shooting
Does Bluetooth GPS require driver?
No, Bluetooth GPS does not require driver to run. As long as the host device supports
Bluetooth and serial profile, it will recognize Bluetooth GPS through discovery mode.
The Bluetooth GPS is successfully paired through Bluetooth Manager. However, the
GPS mapping software can not recognize the Bluetooth GPS.
Only one program can access the GPS at one time. Please make sure all GPS programs are
turned off except for one you intend to use.
The Bluetooth GPS has received satellite signals. However, it can not acquire a fix.
GPS receiver stores the satellite data in the internal memory. If you have not used GPS
receiver for a while or have traveled a long distance, please remove the battery for a while
and let the GPS receiver reset.
The Bluetooth GPS takes long time to get a fix.
When you first use the GPS reciver, please make sure that you are outside with good view of
the sky and stay stationary. It may take about few minutes to locate the satellites for the first
time. However, it will locate much faster during the subsequent uses.
The Bluetooth GPS can not be paired after the battery is completely drained.
When the battery is completed drained, the unique pairing ID is lost. Please delete the
Bluetooth GPS short cut and the paired device from the Bluetooth manager, restart the host
device, and re-pair the Bluetooth GPS again.
How long is the warranty and where to exchange the defective product?
The warranty is one year from the date of purchase. Replacement will be issued directly by
your authorized dealer.
