Changing the variables displaying time The user can set the time during which the display shows one of the variables (for example, temperature) before changing to the other. The time is in seconds. To do this, proceed to the parameter A and press the Advance key. - Page 5 Parameter 2: Time configuration: This parameter configures the time When entering this parameter, the hour can be changed. After pressing Enter, the minute can be changed. When the user leaves the menu, the seconds are changed to 0. Parameter 3: Time offset: This parameter allows the user to configure its time zone, as well as changing the time offset in summertime/wintertime when configuring it manually, or for personal purposes;...

LAN, it is recommended to use the PC program “Display Discoverer”, downloadable from the web www.lartet.com. In this program, the displays connected to the LAN are displayed, as well as their IP addresses, their MAC addresses (all MAC are 00:04:A3:xx:xx:xx) and its name. The default name of the display is its serial number. - Page 9 Tip the new IP and click OK.

Page 11: User Interface
User interface Ethernet connection allows a new interface, much easier than the usual in displays. All configuration can be done through a website hosted at the display, so the user only needs a device connected to the LAN with web browser (computers, smartphones, tablets…). There is no contact with the display, which usually is in a difficult access point. - Page 12 First tab allows the user to configure the same parameters as the parameter menu in an easier and more intuitive way. When the user configures the display to sync through SNTP or another display, the server must be written in the field. The second tab allows configuring the network parameters of the display, including the IP address, DNS, etc.
- Page 13 Ethernet parameter configuration The Ethernet parameters, like the IP address, the Gateway, the subnet mask, etc can be configured manually or automatically through DHCP. Previously, the user must know the IP address he wants for the display. It is highly recommended to change the IP address from the default. Once the user has accessed the Ethernet tab of the display webpage, configure the parameters manually or activate the DHCP protocol for the display to request all the network parameters automatically.
