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.

Factory reset:
There are 2 ways to restore the factory
Method 1: By operating the RESET button, the device can be restored to the
field settings.
Step 1: Power on the device, when the work light of the device
works normally.
Step 2: Press and hold the RESET button until the device emits
(di-di-di) three beeps, release the reset button, the light is off,
and the device is successfully restored to factory settings.
Method 2: The equipment can be restored to the field setting by sending
MODBUS commands.

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
