4G IOT Router Rs232 Rs485 Wifi Remote Control Module With Linux
Operating System
Product Introduction of IOT Router ZHL4921W
ZHL4921 provides RS232 interface and RS485 interface, users can
choose one of them according to the situation, but not at the same
time.
ZHL4921 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.
