IV. FIRST START-UP
In order for the controller to work properly, follow these steps while starting it for the first time:
1. Connect EU-WiFi RS to the main controller using an RS cable.
2. Connect the power supply to the module.
3. Go to the module menu and select WiFi network selection. A list of available WiFi networks
will appear - connect to one of the networks by entering the password. In order to enter
the password, use the arrows and select the right characters. Press the Menu button to
confirm.
4. In the main controller menu go to Fitter’s menu →Internet module →ON and Fitter’s
menu →Internet module →DHCP.
NOTE
It is advisable to check if the internet module and the main controller have the same IP
address (in the module: Menu →Network configuration →IP address; in the main
controller: Fitter’s menu →Internet module →IP address). If the address is the same
(e.g. 192.168.1.110), the communication between the devices is correct.
V. CONTROLLING THE SYSTEM ONLINE
Once the devices have been connected properly, generate the registration code. In the module
menu select Registration or in the main controller menu go to: Fitter’s menu →Internet module
→Registration. After a while the code will appear on the screen. Enter the code in the application
or at https://emodul.eu.
