1. Introduction
The TFAC’s MGL-30 Compact GPS receiver/data logger is about the half size of a
computer mouse. Based on the SiRF star II
TM
chip set manufactured by SiRF
Technology, Inc., MGL-30 supports all features, and maintains the technical
specifications of the SiRF star II
TM
architecture.
MGL-30 is a fully self-contained receiver for the Global Positioning System with
data logger capabilities. Inside the container, the TFAC’s TFAG 30 module and
embedded antenna design provides complete GPS signal processing functionality.
Moreover, MGL-30 is also a mini data logger (up to 15 hours for PVT data, 1Hz
update rate recording) by using SiRF starII GSP2e integrated ARM7TDMI
TM
microprocessor and on-board flash memory.
Two versions of
MGL-30
are available.
MGL-30R
comes with a 9-pin serial
connector, and
MGL-30U
comes with a USB connector. Also both modules can come
with (
MGL-30R
,
MGL-30U
) data logger or without (
MG-30R
,
MG-30U
) data
logger function
. These receivers are well suited to system integrators or users who use
popular PC compatible system, notebook PC, PDA and “off-the-shelf” GPS solution.
MGL-30 can be used as an ordinary real-time GPS locator, and
in the mean time to
log the GPS data to its on-board flash memory
. The type of data to be logged as well
as the data format can be specified by the user in the logging setup. The log rate is
also definable by users. When any of these are activated, the character string is
written to the log file along with the GPS data.That is,
TFAC also provides a
companion proprietary data logger demo software package to provide mentioned
functions above and replays these markers. Please see section 3 “Data logger demo
program” description. As to programming guideline of data logger functionality of
MGL-30
, which is frequently used in advanced embedded system design, please refer
to TFAC supplied another “
Programming Guideline of Data Logger Functionality
of MGL-30
” manual.
MGL-30 can satisfy a wide variety of application for vehicle navigation, tracking or
leisure purpose. In automotive applications, the interior superior architecture supports
advanced tracking capabilities through fast recovery times combined with reliable
operation in “urban” and areas of dense foliage.

Terminal program of Windows 95/98/ME, please setup the COM port connected
with MG-30R (MGL-30R) to:
Baud rate : 4800
Data bit : 8
Parity : None
Stop bit : 1
Flow control : None
2.2 Connecting MG-30 (For MG-30U/MGL-30U, USB type)
Driver Installation :
Step 1. Unzip pl2303v2.zip first. You will find the "serwpl.inf" file in the \PL-2303X
\Win98_me or Win2k_xp directory.
Step 2. Connect the GPS device to the USB port of your computer.
The devices will be detected automatically. Please follow the following
installation procedure until the system asks you to locate the driver file. Please
point out the directory \PL-2303X\Win98_me or Win2k_xp in step 1.
Step 3. The installation on Windows 98/Me is follows. The installation of Win2000/XP is
similar.
Select [NEXT] to specify the location of the driver.

dialog box
pop-up. In this
case, just select
CONTINUE
to execute installation.
Step 7. To check which com port is used by the GPS device, click [My Computer] on
Desktop screen, click [Control Panel], open [System]. On “Device Manager” page,
you will find “Port(COM&LPT)” items prefixed with a “+” sign. Click on the “+” sign
to expand it to check com port used by MG-30.
C:\Pl2303x\Win98_me\Serwpl.inf

IMPORTANT: If users can not setup the right COM port (some mapping software can
only support for "COM1" to "COM4" and GPS device may be assigned to use "COM5"),
you may need to :
* uninstall driver first.
* disable or remove one of the existing COM1-4 ports.
* install driver again.
Step 8. You applications can access the MGL-30U via the "COM" port found in Step 3.
The COM port is for the setup of TFAC’s “GPS NMEA Monitor” demo
software (nmeavw15.exe) and some mapping software which supports GPS
function. For instance, if it shows COM3", you have to switch to the COM port
when you start “GPS NMEA Monitor” demo software. Please notice the action,
it is very important. If you don't setup the right Com port, no matter “GPS
NMEA Monitor” software or other mapping software, it will be unable to
communicate with your computer.

(1) Uninstallation:
Run the program "DRemover98_2k.exe" to uninstall the dirvers.Unzip TFAC
supplied driver program "USBDRV.exe". You will find the "serwpl.inf" file in the
\PL-2303 directory.
(2) If user would like to receive NMEA 0183 navigational data through Hyper Terminal
program of Windows 98/ME/2000, please setup the virtual COM port connected
with
MG-30U (MGL-30U) to:
Baud rate : 4800
Data bit : 8
Parity : None
Stop bit : 1
Flow control : None
2.3 Using GPS NMEA Monitor
Step 1.Copy promptly TFAC supplied demo software “GPS NMEA Monitor” executive
file “nmeavw15.exe” to the directory of interested (common used setup procedure
is NOT necessary in this case). User can utilize such Demo Software “GPS NMEA
Monitor” to check NMEA ASCII output sentences from MG-30U (MGL-30U) for
general evaluation in Windows 9x/ME/2000/XP OS platform in general PC
applications.
Step 2. Double click icon
Step 3. “GPS NMEA Monitor” screen is shown as below.
_____________ Taiwan Falcon Aerospace Corporation ________________
12
Step 4. Choose correct COM port, press “Start” icon, then NMEA output sentences and
general navigation information is shown.
Step 5. If necessary, users can log NMEA data into PC by pressing “Start log” icon. Then
the logged data will be stored into the same directory where nmeavw15.exe is
placed. Default log file name is “GPSLOG.txt”.
.

3 Data Logger Demo Program (for MGL-30R/U)
As we mentioned in the previous sections, MGL-30 can be used as an ordinary
real-time GPS locator (to output general NMEA messages), and
in the mean time it
also logs (stores) the GPS data (default format is shown in section 3.5. TFAC can
modify the format for customer’s design upon request) to its on-board flash
memory
. The TFAC supplied “GPSLOGDM.EXE” is a Win98/ME/2000
application software program that is used to demonstrate and test data logging
functions of MGL-30R or MGL-30U. It will, according to the configuration, start
recording upon power on and stop on running out of storage.
Before using it, users
should turn off or disconnect the TFAC supplied “
GPS NMEA Monito
r” demo
software first. As to programming guideline of data logger functionality of
MGL-30
,
which is frequently used in advanced embedded system design, please refer to TFAC
supplied another “
Programming Guideline of Data Logger Functionality of
MGL-30
” manual.
After that, users may utilize the demo program to:
Login the device
Upload recorded data
Change Recording Mode(by time interval or by displacement)
Set password
Programmable device ID
Clear recorded data
Upgrade firmware
3.1 Getting Connected
First of all, connect MGL-30U (MGL-30R) to the USB/RS232 slot of your PC.
Launch demo program and use “select comport” button (first speed button) to select
the correct COM port connected. When COM port is correct selected, then press
“connect” speed button to connect MGL-30U (MGL-30R). Once the device
detected, users need to enter a 4-digit password to login MGL-30U/R (see Fig. 1).
The device name(MGL-30) and firmware version(2.00) are shown in the message
area. After login all the other buttons will become enabled(see Fig. 2). The logged
data size and total flash memory size are shown in the message area. Sometimes
users may need to retry if the connection or password is failed.
