Modbus MQTT Protocol IOT Router Rs485 To 4G Gateway Data Transmission Device
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.

Local Upgrade
The upgrade needs to apply to our company for the upgrade package files required for equipment operation. And to ensure continuous power supply during the upgrade process. If the power is interrupted during the upgrade process, the upgrade may fail and the device may not work normally.
Upgrade steps
Step 1: After connecting the device through the network cable, open the IOTRouter configuration software and select the corresponding product model to enter.
Step 2: Configure the default parameters of the network port, open
Step 3: Enter the debugging page and select the path where the firmware is upgraded, the local upgrade button will switch to the optional state. Click the local upgrade button
Step4: There will be related upgrade information prompts in the log window. At this time, do not perform any operations and wait for the device to automatically perform the upgrade process. After the upgrade is complete, there will be a message in the log window indicating that the APP upload was successful. The device restart.
