Gateway Modbus Rtu IOT Router Wireless Gateway Support Wifi Hotspot Access

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.

WIFI Hotspot Function of IOT Router

Function description: ZHL4921W version supports WIFI hotspot function. Please choose whether to enable this function according to the device model.
Note: The WIFI hotspot function is normally enabled, and the device needs to be able to access the Internet normally. The hotspot function can be used normally. Devices connected to WIFI need to be set to automatically obtain IP.

Note the case of WIFI name/password
WIFI enable register address: 41041 (0x0410)
Default value: 0x0001

Communication Method

TCP-Client communication
The user can modify the relevant register parameters of the remote server through the host computer to connect the device to the destination remote server.
MQTT communication
The user can modify the MQTT related register parameters through the host computer, so that the device can package the data into the MQTT protocol format.
HTTP-Client communication
The user can modify the HTTP related register parameters through the host computer to enable the device to package the data into the HTTP protocol format.
