Invalid Firmware File (or Comm Error)
|Message text:||Firmware upgrade has failed. This may be because you are trying to upload an invalid file or because of communications error|
|May appear in:||COM access mode; Upgradefunction|
This message means that either you tried to upload an invalid file or that there was a communications error. Check the file you are trying to upload, your serial connection (cable, baudrate, etc.) and try again.
The firmware file you are supposed to upload into the DS depends on the DS model number and also on the way you are performing the upgrade- through the network (auto-discovery and address book modes) or through the serial port (COM access mode ). Firmware download page at <%WEB%> provides complete info on what file to choose. Be sure you understand this information and select a correct firmware file.
