Be absolutely certain to observe the following:
1. Under no circumstances should the device or its power supply be deactivated during the firmware
update!
2. The network connection may not be interrupted. Use a cable connection, not WLAN!
·
For a variety of reasons, the firmware update sometimes does not conclude properly, for example
due to interruption of the power supply. For instance, the "handshake signal" at the end of the
procedure may be missing. In this case, no measurement channels would be displayed initially.
However, restarting the device and its software and performing the firmware update again usually
restores everything to normal.
It may be necessary to call the menu function "Update all components" in the FW-Update dialog's
Options menu. This scenario only results in permanent damage in the most rare cases, and it is very
worthwhile to repeat the procedure before sending a device in for repair.
·
Behaviour under error condition, Windows cuts off the network connection without the user's
knowledge; but this can be prevented using the PC's Control Panel.
Background: During the firmware updates there is no data transfer for a few minutes and thus no
network activity; Windows detects inactivity of the connection and the following mechanisms are set
in motion:
a. Windows' energy saving mode switches the LAN adapter off, consequently interrupting the
network connection!
b. Windows switches to the next LAN adapter if there is one (some PCs have multiple adapters in
order to, for instance, access SAP or Novell in parallel, which are often running on separate
networks.)
c. Other scenarios are feasible, e.g. if switches are activated, which can also respond to missing
data traffic.
If an error message is posted during the firmware update, leave the device on and contact the imc
Hotline. It may be possible to continue the firmware-update under the guidance of the Hotline using a
service program.
The Options menu offers the option to Update all
components. This makes it possible to earmark all
the components of the selected device for an
update. The function is only to be used in
compliance with instructions from the imc-Hotline.
·
A message box will appear to notify you if and when the firmware-update has been completed
successfully.
·
The File menu offers a function for working with the log file. Every action taken during a firmware
update plus any errors which may occur are recorded in a log file. This log file can be displayed with
menu File > Show log file
·
The firmware belonging to the amplifiers installed in the device is only updated if there was a
firmware change along with the respective imc STUDIO software version.
