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.)
