Why can’t I assign an IP address through the serial port?

1. Regardless of the serial transmission parameters set for normal operation, the Web Thermometer expects for entering the "x" characters (=ASCII 120) on boot-up always the transmission format 9600 baud, 8 data bits, no parity.
2. For assigning the IP address, the terminal program used should be configured to "No handshake". Specifically in the case of the Web-IO 1x Thermometer, problems may occur because a measurement input is connected to the DTR pin. You should preferably use a serial cable here for which only the data lines (pins 2.3) and ground (pin 5) are connected through. For serial IP assignment, we recommend using our tools. 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.
3. The Web Thermometer only reacts to the lowercase letter "x" (=dec 120 = hex 78). Thus, if the CapsLock function is left switched on by mistake, the received characters are ignored.
