How can the Web Thermometer be reset to its factory default settings (factory defaults)?

1. The Web-IO 1x Thermometer #57601 can be reset via the Telnet configuration menu using the port number 1111. Following selection of the relevant menu item in the "System setup" and confirmation with "Y", the Web Thermometer closes the Telnet session, executes a reset and loads its factory default settings. In the process, the IP address is reset to 0.0.0.0, which enables reassignment with the aid of a static ARP entry (see also note)

   Note: In the case of a possible check of whether the Web Thermometer was really reset to its factory default settings, the dynamic ARP entry generated by the previous Telnet session must first be deleted. If this is not done, the Web thermometer takes the destination IP address contained in the first of the packets directed to its MAC address and saves it as its own.
   Command for deleting an ARP entry: arp -d [IP address]

2. In the case of all models, the possibility exists of resetting the relevant device via the serial interface. If, during the boot procedure, the Web Thermometer receives a continuous data stream (data format 9600, n, 8) having the content "f" (= ASCII 102), the procedure is started for resetting the device to its factory default settings. For this purpose, it is necessary to connect a network cable or else the device will not restart fully. The Web thermometer twice acknowledges the receipt of the sequence and the initiation of the process by repeatedly flashing the "On error http" and "System error" LED. After approx. 10 seconds, the procedure is completed. All network settings are also lost in the process. Reassign the IP address.
