TGW-100 Firmware update procedure
The update mechanism of the TGW-100 was introduced with firmware version 1.16.
Previous versions can not be updated by this method, for such devices please contact
your Piciorgros partner who will be able to upgrade the devices to at least this version.
To perform the update, just a TFTP client is needed. A simple command-line client is
built directly into Windows operating system.
6.1.1
Preparation and setup
For updating the TGW-100 you will need the following equipment:
PC with Ethernet connection
TFTP client software (Windows command line or i.e. "PumpKIN" software)
Firmware files for the TGW-100
6.1.2
Update procedure
For the update, two firmware files are needed. The file with the extension ".pfw" is the
firmware file, the one with the extension ".pch" is the keyfile to activate the loaded
firmware.
To perform the update, the ".pfw" file must be sent first to the TGW-100. Unless the
".pch" file is sent to the TGW-100, the device will just store the new firmware file.
As soon as the matching ".pch" file is also transferred to the TGW-100, the device will
restart and reprogram itself to the new firmware.
Important!
This reprogramming after sending the ".pch"-file to the device will
take about 15-20 seconds. During this action, DO NOT INTERRUPT
THE POWER TO THE TGW-100. Otherwise the update fails and the
device must be restored by a Piciorgros partner.
After the update process has ended, the device will start immediately with the new
firmware.
