How can I reset the NET-PwrCtrl?
Should the NET-PwrCtrl - which we do not hope - react to anything - it should first
be reset:
Important! If IP bar has been changed or DHCP has been switched off, the
browser will assign the host name to the wrong IP. To refresh the assignment to
the new IP:
1. Browser (all windows) must be closed.
2. Run nbtstat.exe -R (as administrator) to clear the mapping.
3. Start the browser and call up the bar with the host name.
Press the reset button (small hole next to the power socket) for approx. 5
seconds, this will reset the NET-PwrCtrl.
The following happens in the NET-PwrCtrl:
1. The NET-PwrCtrl restarts.
2. Fast flashing (ready for programming = bootload)
3. Programming the standard parameters.
4. The NET-PwrCtrl restarts.
5. Fast blinking and after 1-2 sec. 1 time per second = normal condition.
Load firmware without access to the NET-PwrCtrl
Should there be problems when loading the firmware (power failure, interruption of the network
connection), the process can be repeated without access from the browser:
Switch off the firewall for the duration of the transmission. Not directly on the PC and over WLAN.
ŸStart NET-loader.exe. Of course, the "net-control.hex" file must be in the same directory.
ŸPress reset button.
ŸThe fast flashing of the LED signals the download.
ŸAfter the NET loader program has finished loading,
browse the device via browser: http://net-control
If the NET-PwrCtrl is not accessible, it must be reset.
