imc CRONOSflex Getting Started Version 1.8 - 08.01.2014
Firmware-Update
39
The following symbols for the individual firmware components appear in the list:
not current
firmware conforms to current standards
error occurred during update procedure
this option is not available on the device
Select the device to be updated and then the softkey
Update
.
During the update, which can last up to several minutes, a progress indicator appears.
Do not interrupt the firmware update!
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. Windows switches to an alternative IP-address which can be set (so-called fallback address or
alternative-IP; the settings depend on the respective LAN driver) This case is widely prevalent
especially in companies having an IT administration. As of Version 2.7R3, this case is circumvented.
d. 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.
