Firmware Analyses

Firmware:

h t t p://hilfe.telekom.de/dlp/eki/downloads/Eumex%20Serie/Eumex_800/fw_Eumex800_1.21_RC01.exe

Run this small programm with wine to extract the firmware file: "fw_Eumex800_1.21_RC01.fwr"

After downloading and extracting the firmware gives me "hexdump -C fw_Eumex800_1.21_RC01.fwr":
