3.3 Settings of the operating system
3.3.1 (Firmware) update for the operating system
The operating system of the IE-GPRS-I/O is subject to continuous
further development to adapt it to the technical requirements and
customer wishes. Devices which are already in use may thus also
require a new operating system. The version of operating system
currently installed on your IE-GPRS-I/O can be displayed on the About
page of your web browser (see Section 4.16 About) or read out using a
terminal program (see Section 3.4.1).
When loading a new operating system, it may be necessary to reset all
settings to the factory defaults.
If the IE-GPRS-I/O is reset manually to its factory default settings
after installing the operating system, all settings already made are
lost; the user name and the password are also reset to the factory
defaults. Therefore, you should always document the current
settings before you make an update!
After the update, check both all settings and the access
protection.
To load the operating system, use a loader.
Files required: gprs-flash.exe Loader
ie-gprs-io-xxxxx.hex Loader file
xxxxx stands for the version number
It is not necessary that both files are in the same directory.
• Connect the RS232 of your IE-GPRS-I/O to COM1 or COM2 of
your PC.
• Turn off the IE-GPRS-I/O.
• Set the DIP switch to 0-0-0-1.
• Turn on the IE-GPRS-I/O.
• Start gprs-flash.exe.
• Set the COMx interface and select the baud rate 115200.
• Select the loader file.
• Type flash it to start.
