ETAS Troubleshooting Problems
• In order to reactivate the network adapter right
click on it again and select Enable.
Cause: Laptop power management deactivates the network card
The power management of a laptop computer can deactivate the network card.
Therefore you should turn off power monitoring on the laptop.
To switch off power monitoring on the laptop:
• From the Windows Start Menu, select
– Windows XP:
Control Panel System.
Then select the Hardware tab and click on
Device Manager.
–Windows Vista:
Control Panel System and
Maintenance Device Manager.
• In the Device Manager open the tree structure of
the entry Network Adapters.
• Right click on the used network adapter and select
Properties in the context menu.
• Select the Power Management tab and deactivate
the Allow the computer to turn off this device
to save power option.
• Select the Advanced tab. If the property Auto-
sense is included, deactivate it also.
• Click OK to apply the settings.
Cause: Automatic disruption of network connection
It is possible after a certain period of time without data traffic that the network
card automatically interrupts the Ethernet connection. This can be prevented by
setting the registry key autodisconnect.
To set the registry key autodisconnect:
• Open the Registry Editor.
• Select under HKEY_LOCAL_MACHINE\SYSTEM\
ControlSet001\Services\lanmanserver\
parameters the Registry Key autodisconnect
and change its value to 0xffffffff.
6.2.3 Personal Firewall blocks Communication
Cause: Permissions given through the firewall block ETAS hardware
Personal firewalls may interfere with access to ETAS Ethernet hardware. The
automatic search for hardware typically cannot find any Ethernet hardware at all,
although the configuration parameters are correct.
Certain actions in ETAS products may lead to some trouble if the firewall is not
properly parameterized, e.g. upon opening an experiment in ASCET or searching
for hardware from within INCA or HSP.
