GlobalTrak â„¢ GT Lite Operation and Maintenance Manual
3.1 Updating the Main Processor Software
The main processor contains two types of code: Low level firmware and application software.
The firmware contains the operating system as well as GSM controls. This code transparent
to the user and is rarely ever changed. The application software contains the device behavior
and is visible to the user. This section defines updating the application software.
Programming over Serial
Programming the GT Lite over serial (RS232) is a direct connection to the main processor’s
serial bootloader. This method does not require any cellular connection, but it does require
opening the GT Lite enclosure. Also, this is the only method to program a blank processor
(no code) or a processor that has been recovered (see 3.3).
1. Remove the four case screws to open the GT Lite enclosure.
2. Locate J29 as shown in Figure XXXXXXXX below.
Figure XXXXXXXXX
3. Move the jumper to the programming side as shown in Figure XXXXXX below.
Figure XXXXXXXX
4. Connect the GT Lite debug cable to the external Conxall connector. Connect the serial
(RS232) end of the debug cable to a PC.
5. Open a HyperTerminal connection to the COM port in which the GT Lite is connected.
6. Modify the connection properties to match Figure XXXXXX below.
