Reset switch:
also known as DEF switch, as shown in figure 5. When the
DEF switch is On (the right side of figure 5 is On), the serial device server will
start loading the default parameters, and when pressed to On state for 5
seconds, the default parameters will be used to restart. The default
parameters only affect the following parameters: IP mode to static, IP address
to 192.168.1.254, subnet mask to 255.255.255.0, gateway to 192.168.1.1.
Other parameters such as baud rate will not be reset. If all parameters need to
be reset, please use the "system default parameter" of ZLVircom configuration
tool for modification. The DEF switch is mainly used to make it easy to enter
192.168.1.254 in the browser to reconfigure the device when the IP is
forgotten. The Protect switch is for future use.

communication link with the upper computer.
