Since Version 1.3 a Networker web access must be authorized with username and password. Three different user accounts are differentiated:

Do not forget to alter usernames and passwords in the user administration dialog!

Reset to factory settings

The factory settings are:

Reset to factory settings at Networker Usually the Networker can be reset to factory settings via the start page of the webinterface. If the administrator password is lost or the IP settings are wrong, Networker is not configurable nor updateable anymore. In that case the Networker configuration can be reset to factory settings directly at the Networker hardware. The PGD pad should be pulled down with a resistor (1K) to ground during a Networker restart. As soon as Networker "hangs" (means does nothing) the installed resistor should be removed. If Networker starts flashing the network jack LEDs the reset was successful. Afterwards a restart is performed.

The firmware is constantly under development. New features arrive and bugs will be fixed. The releases are published here as intel hex files:

The Networker web interface is available in English, too.

Updates in operation mode

The update is done with a PC via the network. The hex file should be stored to hard disk before. The file is transfered to the Networker via tftp. For the update therefore a tftp client is needed. At the most operating systems such a client is included.

Since Version 1.3 the Firmware update has to be explicitly activated via the Networker web interface (logged in as administrator). This eliminates a potential security risk of Networker. In the common settings a radio group can be found:

The file is transfered to Networker with the TFTP PUT command. Networker is accessed via the current IP address or the network name. Example for a tftp command in a shell box under Windows:

tftp ne7C4000.local put "Netzer.hex"

Networker goes into the update mode automatically and the file is transfered. A running transfer is indicated through the network activity LED, which is emitting for about 20 seconds. After the transfer has finished successfully the tftp client prints out that message:

Successfully transfered: 335139 bytes in 16 seconds, 20946 bytes/s

Updates in bootloader mode

The bootloader mode is active for aprox. 2 seconds after power on. After this time Networker enters the operation mode. The active mode is indicated due the fast blinking network LED. In bootloader mode Networker has the fixed IP address and MAC address 00-04-A3-00-00-00. Updating only works if this IP address is not already occupied. The updating process works analog to the update in operation mode.

Important: Only one Networker is allowed to be in Bootloader mode when starting the update.

Networker Website

On the Networker websites common settings can be done and informations can be requested. For a first try this websites were mirrored to this project pages (from the latest release, logged in as administrator). Here is the link to the website: Link
