To update the firmware, you will need to connect a PC-Link cable(see Figure 1) from the connector [17] on
the BTEL-GT to one of the COM ports on the PC; the BTEL-GT FW Update application and the update files
can be downloaded from the Bentel website. Make sure you insert the PC-Link cable connector in the right
way. Once the connection is made, choose the COM port that is being used and the update file and click on
the Next button: the application will show some information about the device that is connected. Click on Next
to proceed with updating the firmware. Check the serial link and the serial port settings in case of communication
problem, or use a different USB-RS232 adapter.
To install and run the "BTEL-GT FW Update" application, you will need to log on to the PC as
the Administrator; we also recommend that any anti-virus programs and/or firewalls are
disabled if problems arise while the application is being installed.
