Troubleshooting:  Serial to Ethernet Converters-Cannot search the device

1. Check the hardware connection: 

a. Whether the power supply is normal

b. Check whether the network port lights are normal: The green light is always on and the yellow light is blinking.

c. Whether the module is directly connected to the computer through a network cable. If so, it is recommended that set the computer to the following parameters:

IP: 192.168.0.201.

Mask: 255.255.255.0

d. If not, ensure that the device and computer are in the same network segment. Check if they can ping each other.

2. Check if the computer status is normal:

a. Check if anti-virus software and firewall are turned off.

    (Some anti-virus software and firewalls will block unfamiliar ports, anti-virus software will report viruses to unused software)

b. Whether the computer has dual network cards.

    (Please turn off other network cards during the test.)
