Resetting IP Address
When the LEDs of all binaries are on or you do not connect to the device according to the relevant settings, you must reset the device IP using the dongle. Before resetting the device’s IP address, it is necessary to make sure that the device is turned off. Then, the RS232 dongle is connected to its specific port on the back of the device.
Upon turning on the device, you can see that, the error lights of the device will start blinking
After blinking several times, there is a pause and then the device will start blinking again. After this process is repeated for the third time, the user should turn off the device and disconnect the RS232 dongle from the back of the device
Now, the IP address of the device is reset and its serial for connecting via Wi-Fi is changed to 199. After turning on the device, to establish the connection between the device and the laptop, enter “199” in the fourth part of the IP field on the “Setting” page.
Note that if you do not have a dongle or even an RS232 port, you can use a thin wire to do it. As can be seen, it is enough to connect pins 2 and 3 with a thin wire.
