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.

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
