How do I reset the Web-IO to its factory default settings?

1. The standard way of restoring the factory default settings is via Web-based management. After the administrator logs on, the Web-IO can do this via Config >> Session Control >> Logout >> Factory Defaults. In the process, the IP address is reset to 0.0.0.0 which enables a reassignment with the aid of the WuTility tool or of a static ARP entry.
2. In the case of Web-IO with serial Com-Server functionality, it is also possible via the Telnet configuration under the port number 1111. After selection of the relevant menu item in the “System-Setup” and then confirming with “Y”, the Web-IO closes the Telnet session, performs a reset and loads its factory settings. The IP address is then reset to 0.0.0.0, which allows you to reassign it using the WuTility tool or a static ARP entry (see also Note)
3. If the current IP address of the Web-IO is not known or if it is not compatible to the specific network, the factory default settings can also be restored via the serial interface. To do this, after being reset, the “f” character must be sent to the Web-IO continuously for approximately 3 seconds. For this purpose, the serial interface is connected with a free COM interface on the PC. Independently of the serial transmission parameters set for normal operation, for the input of the “f” characters in the course of the boot process, the Web-IO always expects the transmission format 9600 baud, 8 data bits, no parity. For the assignment of the IP address, the terminal program being used should be configured to “No handshake”. On starting, although the Web-IO sets its handshake outputs RTS and DTR to the enable state, serial cables which are not fully wired might otherwise cause problems. For the serial IP assignment, we recommend that our tool be used Easyterm. Alternatively, it is of course also possible to use other serial terminal programs, such as e.g.Hyperterminal with direct connections to the relevant COM port.

Note: For a possible check of whether the Web-IO is really switched to its factory settings, the dynamic ARP entry previously generated by the last Telnet session must first be deleted. If this is not done, the Web-IO takes destination IP address contained in the first of the packets directed to its MAC address and stores it as its own.
Command for deleting an ARP entry: arp -d [IP address]
