Product Introduction of IOT Router ZHL4921W

ZHL4921W provides RS232 interface and RS485 interface, users can choose one of them according to the situation, but not at the same time.
ZHL4921W provides a RJ45 network port. The device acts as a server, and it automatically monitors the fixed IP address 192.168.225.1 of the machine and the fixed port 50000. The upper computer is used as a client connection device for debugging configuration.
If the device connected to the network port needs routed Internet access, you only need to set the device connected to the network port to automatically obtain IP mode. After a while, you can obtain the IP address through the network port, and you can route to the Internet at this time. For example, webcams, computers and Internet.
