a. Insert the SIM card before connecting backup battery or Micro-USB cable, see Figure 3 left image. Note
the SIM card’s notch faces outwards towards edge of device. Next, connect the ST4500’s back up
battery, see Figure 3 right image. Note the Red wire on the connector should be towards the inside of
the device. Tuck the extra length of wire into the device to prevent pinching during assembly.
Figure 3: Install SIM card first then connect backup battery
b. Once the SIM card is inserted and back up battery connected, insert the Micro-USB cable into the ST4500
and connect to a PC, see Figure 4. The ST4500’s red and blue LEDs will begin to blink on either side of the
ST4500’s case indicating the device is powered up and ready for configuration.

5. Connect the ST4500 to SyncTrak
a. Open SyncTrak. The Welcome view is displayed while the program attempts to auto-connect with the
ST4500. Once connected SyncTrak switches to the Network Parameters settings tab, see Figure 5.

b. If SyncTrak does not auto-connect to the ST4500 check the following:
i. USB to Micro-USB cable connection between the ST4500 and PC is secure.
ii. Check the COM port assigned to the ST4500 by the PC. Open Windows Device Manager and
expand Ports (COM &LPT). The ST4500 will initially connect as “MediaTek USB Port (COMxx)”
then expand to “MTK USB Debug Port (COMyy)” and “MTK USB Modem Port (COMzz)”. SyncTrak
will use the MTK USB Modem Port to communicate with the ST4500, circled in green in Figure 6.
Note: Your PC may assign a different COM port value.
Figure 6: Window's Device Manager: Ports (COM & LPT)
iii. In SyncTrak, click the Comport USB drop down list, highlight the COM port noted in Device
Manager and click the Port Open button, see Figure 7, COM56 used as an example.
Figure 7: Select the COM por then click Port Open
c. SyncTrak Basics:
i. The SEND button must be clicked to save modified settings in the current SyncTrak tab view
before navigating to a different SyncTrak tab or closing the program. If the SEND button is NOT
clicked all modified settings will return to prior values. SyncTrak will display the device’s returned
“OK” string in the command history box indicating success, see Figure 8.

ii. In most cases SyncTrak will display an error message when out of range values or conflicts
between settings are sent to the device, see Figure 9. If this happens review and evaluate the
last change made in SyncTrak.

6. Configuring Network Parameters with SyncTrak
The following instructions and settings are the minimum necessary to establish communication between a Suntech
device and network/server, all other device settings will be at default values. NOTE: Incorrect Network Parameters
may prevent the device from connecting with network or server and is not indicative of a failed device. To fully
configure the device please see the Related Suntech Documentation at the beginning of this document or contact
Suntech Support at [e-mail].
Figure 10: SyncTrak Network Parameters, default values shown
a. Navigate to the Network Parameters tab, refer to Figure 10 above as needed.
b. Authentication(1000): Refer to the carrier for required SIM card authentication:
i. If using a major carrier's SIM card and are unsure of the APN, select Automatic to start.
ii. If you know the SIM card’s APN, select None and enter the APN in the next field.
c. APN(1001): Enter SIM card’s APN.
d. User ID(1002), User Password(1003), PIN Number1004):
i. If no User ID, Password or PIN is required: select None in Authentication(1000).
ii. Contact Suntech Support if you require the use of the User ID, Password and PIN fields.
e. Server IP(1005): Enter Server IP address (or URL).
f. Server Port(1006): Enter Server Port.
g. Server Type(1007): Select Server traffic type: TCP or UDP.
h. NOTE: Click the SEND button before next steps!
i. Navigate to the Diagnosis tab in SyncTrak to monitor GPS and GPRS Status, most common indications:
i. GPS Status:
1. Fixed: GPS location fix established, typically less than 1 minute.

2. Not Fixed: GPS has not established a location fix yet. Up to 3 minutes may be necessary
to establish a location fix if any of the following have occurred:
a. Device is inside a building.
b. Device has been moved more than 1,000 kilometers while powered OFF.
c. Device has been powered OFF for several weeks.
ii. GPRS Status (optional):
Note: In order to check GPRS status the ST4500 must be connected to minimum 12vDC power
via the OBD2 connector on the device. This can be accomplished with either an OBD2 port
connector cable supplying 12vDC, or, the device can be inserted into the OBD2 port of a vehicle.
1. OK: Device is connected to the carrier network and customer’s server.
2. Limited Service or Server Communication Error:The Server IP or Port is not
correct. There may be network traffic on the SIM card, but the server may not be
receiving all packets from the device.
3. No Network: Device cannot reach the carrier network. Check Authentication(1000) and
APN(1001) settings or the SIM card is not activated.
iii. A correctly configured device will indicate GPS: Fixed and GPRS: OK, see Figure 11.
Figure 11: SyncTrak Diagnosis Tab
j. Navigate to the Command tab.
k. In the drop-down menu select "StatusReq" to send a status report to the defined Server IP (or URL) to
confirm device is reporting as expected.
7. ST4500 Assembly and Installation
a. Disconnect the USB to Micro-USB cable from the ST4500.
b. Set the lid back onto the base taking care to not pinch the backup battery wires in the edges of the case.
c. Insert and tighten the 4 assembly screws provided with the ST4500. Use a PH#1 or PH#2 size screwdriver
or torque driver (1.5 +/- 0.2 in-lbs recommended).
d. Install the ST4500 into the OBD2 port of the vehicle.
