Part 2 Features  
WBT-100 is the GSP receiver with internal antenna. iTrax 03 used in its core is high-tech  
component and is integrated with electronic compass to the effect of providing more accurate  
GPS data(this innovative concept is patented by Wintec) especially during navigation when  
the vehicle is moving slowly.  
It can also auto-log record of journey, which are useful in navigation, security tracking purpose,  
map making and other agricultural needs. USB connector ensures easy linking with other  
electronic devices.The GPS acquisition status, the last record of time and position can all be  
stored in unfailing memory. It has 12 GPS channels and its low power-consumption can last  
continuous 9 hours of operation. WBT-100 can boast of its smallest size ever with fullest  
features in the world.  
WBT-100 uses iTrax 03 GPS module (the 3rd generation) and the high-performance CPU  
(ARM7TDMI CPU)  
Maximum 12 channels can be acquisitioned quickly  
Internal decode”WAAS/EGNOS” is used excluding the need for external hardware in  
receiving WAAS/EGNOS signal  
System supports NMEA0183 3.0 for data transfer  
Internal electronic compass is used to get the compass/GPS inter-calibrating effect  
Electronic compass can work independently to find north  
With the integral support of electronic compass, NMEA data output can make navigation  
more reliable  
Data-logging acts like the in-flight black box and can record of position, date and time as  
long as power source is maintained  
For down-load of log-data and programming of WBT-100, provided software tool “G-tool”  
can simplify usage  
The system is upgradeable with new software which is provided free from us  
It is designed to be water-proof  
Data link thru blue tooth within 10 meter range

Part 4 Safety Notes  
GPS (Global Positioning System) is provided by the United States government. Its  
accuracy may varies depending on special conditions (area at war or if it is blocked). Any  
control by USA will affect this system and its accuracy.  
If installed on the transportation device, driver must not operate this while driving  
GPS performance is effected when satellite coverage is degraded as near a high-rise  
building, in the tunnel or under a cover  
Personal replacement of components and re-structuring of this is prohibited and may  
result in loss of legal usage  
Operation of this device is strictly prohibited in highly explosive environment such  
mining ,in-flight or other unauthorized area against use of this  
Avoid exposing this at places of high temperature and humidity  
Return to original dealer immediately if it emits strange smell or fume

power adaptor , installation Disk, Quick use guide  
WBT-100 Operation  
Temporarily press power button to turn it on. The blue tooth and GPS status led will  
glow to confirm it is in GPS mode  
GPS Led glows red to show GPS acquisition is done ( 1 Hz). But if this led is solid on,  
the GPS acquisition fails.  
Temporarily press on power button. Blue tooth will turn off after blue tooth led goes off.  
Another press on power button can turn blue tooth on after its LED glows again.  
Temporarily press on mode button each time can switch between compass mode  
(LED glows green) and GPS mode (LED glows red)  
It is strongly recommended to have WBT-100 calibrated in any  
environment ahead of use. Press and hold the mode button to enter  
into calibration status which is displayed by orange LED. Press shortly  
again the same button to get out of calibration status and remain in  
compass mode (LED glows green). But if calibration fails, it will jump  
into GPS mode (LED glows red in this situation)  
After power on, press and hold power button to turn the power off.  
If red LED starts to blink, the power is low and needs recharging. Led stays solid while  
charging .It glows green after it is fully charged.  
When the USB is used as interface:-  
USB driver must be installed first  
After connection to USB port of computer, place the WBT-100 suitable  
area where it can best receive GPS signal for acquisitioning  
Power it(or switch its power on)  
WBT-100 will start acquisition  
When the blue tooth is used as interface:-  
Ahead of blue tooth connection, make sure the target device to pair  
can support blue tooth SPP master  
After pairing with WBT 100, place it at suitable area where it can best  
receive GPS signal for acquisitioning  
Activate the software of paired device. WTB 100 starts to provide GPS

Battery charging  
Connect WBT 100 with USB cable and turn on power source  
To charge it , power source can be supplied from USB host from  
computer, or from power adapter or car cigarette lighter adapter  
Part 6 Operation notes  
WBT 100 will do self-check once it is powered. Blue tooth and GPS start to work when  
both blue and red LED turns on. GPS automatically starts acquisition and auto-logs. If sky  
is clear overhead, it requires only 40 sec for acquisition. (If the data in its memory is still  
valid, it needs only 8~35 sec). After acquisition, WBT100 starts output data of position,  
speed and time in NMWA0183 format.  
For the first time if it is placed at the area well exposed to the satellite signal, this device  
requires approx 13 min (theoretically 12.5 min) to receive or update Almanac. Refer to  
trouble shooting guide when signal is not received well.  
If WBT-100 formatting the internal data is not correct, or if satellite data has been deleted,  
it takes longer time to position. But under the following conditions, it can take even longer  
time to do cold start.  
If it is not in use for over 3 months (the almanac to too old)  
If the recorded data is over 500 km  
After positioning, WBT-100 transfers navigation data thru export interface as below.

Data can be read out thru USB or bluetooth  
Data includes latitude, longitude, time in year-month-date-min-sec  
After successful positioning, it wills automatically auto-log GPS data into its internal  
memory chip. Use G-tool to program log interval (1~ 3600 sec). The factory default is  
set at 5 sec interval for the auto-logging. If interval is set to 0 sec, this auto-log  
feature is deactivated. Log data is recorded in a rotational order. The earliest (oldest)  
data will replaced by the latest (newest) one when memory space is full (when data  
excesses 12680 maximum).  
Auto-log will continue even if the Bluethooth is off.  
If interval 0 sec is set, auto-log stops to work. Its power will be off after 10 min the  
Bluetooth is switched off. Auto-log will not shut down if interval is set higher-than 0 sec.

Part 9 Trouble shooting guide  
The GPS signal will become weak under the following conditions  
If the vehicle enters the tunnel.The GPS signal transmits linearly down to earth and its  
signal is blocked out in this situation.  
GPS satellite coverage gets poor because of high-rise building or thick forest. Even  
though WBT-100 can receive reflected weak GSP signal , the data might be less accurate  
The sun shade in the vehicle can partially block out GPS signal and effect good reception.  
The GPS satellite is under control of USA and the accuracy might vary depending on  
some special purpose(as may be required by USA)  
It is a normal situation when GPS data displayed by the receiver device shows a big  
difference from real position because of unstable atmospheric condition which causes  
GPS axis to drift from actual map axis occasionally  
Some navigation softwares can only decode latitude/latitude from NMEA0183 provided by  
logger. No altitude information is available and therefore it cannot define vehicle’s positioin  
whether the is over or under the bridge.  
After successful positioning of WBT-100, if it is moved to another area of 500 km away it  
cannot be easily re-positioned. This is because the firstly recorded data(position, time and  
number of satellites acquisitioned) is different from the new area. It will need longer time  
for re-positioning.

When the power LED flashes red, the battery is critically low and needs re-charging. If it is  
not recharged within 30 min, GPS will stop to work to prevent total exhaust of power.  
PIN code will be requested after Bluetooth connection initiates between GPS and PDA.  
Enter code as 0000.  
Bluetooth connection takes 5 sec for self-check. Each time the device is switched on, it  
needs 5 sec before connection  
It is normal if the Bluetooth coverage might become short sometimes due to  
environmental interferences.  
Avoid placing 2 GPS devices too close during positioning.  
USB driver must be installed first before connecting the device to the USB port of  
computer. Make sure of the right COM PORT being used.  
If disconnection between PDA and GPS is done in a normal way, PDA will halt. Try to  
disconnect Bluetooth connection in a standard method.  
If the WBT-100 is found to work abnormally because of wrong procedure, reset it by  
taking off the battery. It will have factory default without effecting pre-set program. At the  
factory default, GPS reception begins in a quick start mode and its position may take  
longer time.  
If USB cable will be used for the connection of WBT-100 and PC, install the USB driver  
first on the PC and make sure of right COM PORT.  
If WBT-100 is used for navigation but found unworkable after connection is done. Make  
sure that the software NMEA0183 is used. Then use G-tool(Refer to the G-Tool operation  
guide )  
If the compass direction is not accurate, re-calibrate the WBT-100. Follow the calibration  
procedure.
