A. Applications
AVL-921 is a GPRS data transmitter with RISC CPU for fast data processing. It
comes with GPS module and GSM/GPRS module; is an ideal device for fleet
management. Besides, the six I/O ports can be connected with barcode
scanner, keypad, LCD/ LED display, ADC (Analog to Digital Converter)...,
which enable it to integrate data for perfect remote communication, remote
monitoring, and remote control.
AVL-921 can be used for following purposes:
Vehicle positioning
Fleet Management
Two way phone conversation
Remote monitoring of rainfall
Remote monitoring of temperature
Remote monitoring of traffic condition
Remote monitoring of water level in rivers
Remote monitoring of electronic ammeters
Features
8 bit RISC CPU, can be upgraded to 33 MIPS
6 RS232 ports for data input/ output (RJ45 interface)
built-in 128K Flash ROM memory for programming
can come with 32K SRAM
can come with 16K EEPROM
Power Source: 12-36VDC @3A
can be connected with a buzzer

C. Hardware Installation
1. Check if all the parts are included in the package.
2. Prepare a SIM card for GSM/GPRS communication (make sure the GPRS
function has been enabled). Use some other mobile phone to confirm that the
PIN code ahs not been set, and that it can dial out and receive telephone calls
without problem.
3. Before install the SIM card, make sure to cut off power from the AVL unit. The
correct installation method is to push the tray completely into the AVL, until you
feel it is hooked by something.
4. Find a suitable to install the AVL unit; and put the external GPS antenna at a
place able to see the sky - not covered or shielded by any other object
containing metallic material.

5. Check if all the wiring has been connected correctly; connect the AVL unit to the
power source (12 or 24 VDC). Switch the power button to “ON” (above figure
marked with “D”); then check if the Power LED (above figure marked with “A”)
is on.
6. Check if the GPS LED (above figure marked with “B”) blinks regularly to confirm
the AVL unit has already got a position fix.
7. Check if the GSM/GPRS LED (above figure marked with “C”) blinks regularly to
know if GPRS network does work properly.
8. Fix AVL Unit
Put the AVL unit on the floor under the driver’s seat, and fix it on the floor carpet
with strong adhesive double-sided tape; then fasten the other parts/ cables.

D. Functions
1. LED Indicator
a) POWER: Red light; will be steady red light after power on.
b) GPS: Green light; will flash when receiving GPS signals.
c) GPRS: Orange light; will flash once per second after power on; and 3 times
per second after GSM/ GPRS network connection is successful.
2. Power Source
12~36V@3A; power cable with error-free connector design.
3. RS-232 Ports
Six I/O ports with RJ-45 interface for data input/ output.
4. SMA Socket
With 2 SMAsockets for GPS antenna and GPRS antenna.
5. Function Key
Users can define the functions of F1 & F2 keys. The LED will be on, when the
function key is pressed down.
6. SOS Button
Press this button to summon help to the exact location, when under
emergency circumstance. The SOS indicator will be on, after then. Please call
the control center to cancel the status, if SOS button was activated by mistake.

F. Q & A
1. Why Power LED is not “ON” ?
Check the connection of DC Power. Is it connected properly ?
Does the power source meet 12-36V@3Arequirement.
If the Power Button has been switched to the right-hand side.
If there is no problem with the power source and power switch,
then please check the wiring of PG circuit.
2. Why Green LED does not flash ?
Check if GPS antenna is correctly installed, or if it is placed at a proper
location, where it can well see the sky.
Make sure there is not any metal material, such as windshield heat insulation
paper with metallic content, above the GPS antenna – which may block the
reception of GPS signal.
Do not park your vehicle under shielding or under a building.
If necessary, put the GPS antenna outside the car temporally.
3. Why Orange LED does not flash ?
Check if GPRS antenna is correctly installed.
Check if the SIM card has been installed correctly.
Make sure the SIM card does support GPRS communication.
Please do cut off power, before insert or remove the SIM card.
If the vehicle is parked in a place where GSM signal is weak.
Check if the GSM/GPRS module sits definitely on the board.
Re-boot your system, to see if the problem can be solved.
