Note Protection Mark according to DIN 34!
Attention: The file to be loaded is "Firmware.bin", which is a binary file. To avoid
malfunctions, only files approved by coM.sat should be loaded into the device.
In case of a power failure during reprogramming of the device or any other event that
invalidates the program storage of the ISDN Basic, there is another tool that can
program a new firmware even if the device is inoperable. The fload program located
in the firmware directory is a command line based tool for programming the ISDN
Basic. The fw_upd.bat batch file calls this program. Before using it, verify that it uses
the correct COM port in the command line of fload. Then keep the reset button of the
ISDN Basic pressed until the power LED is switched off for a moment. Release the
reset button and run the fw_upd batch file. The firmware will be updated and after
completion, the device must be reset again.
If the firmware shall be restarted, this can be done with the command ”Reset” in the
”Firmware” menu. This issues the command AT$R to the device. This command can
also be entered manually in the terminal. It requires a log in.
