1 Network Configuration and Address Management

Connecting: Wired and Wi-Fi

The device supports wired LAN and Wi-Fi. For long-term operation prefer a cable:

• stable address, immune to wireless interference;
• independent of Wi-Fi password changes;
• suits sustained screen pushes during peak hours.

Plug in the cable and the device gets a LAN address automatically. The managing computer must be on the same subnet.

Wi-Fi setup from the web:

1. Log into the editor and click "Network Setup" on the top bar.
2. Nearby Wi-Fi networks are scanned and listed by signal strength.
3. Pick one — open networks connect directly, secured ones need a password.
4. Click "Connect".

During connection the system drops the current wireless link first and retries the target up to 3 times; on failure it falls back to the original network, and only after that fails too does it stay on the setup page with an error.

On success the page shows the new service address and redirects after 5 seconds. The device screen overlays a "network switched + new address" card while keeping the background and numbers; it reverts to the normal canvas after 5 idle minutes.

On-Screen Network Setup

When offline the device enters the "wireless network setup" view, fitting sites without a computer:

• ↑ / ↓: pick a Wi-Fi network;
• Enter: open password entry or connect;
• mouse click: select a network;
• press Enter after typing the password to connect;
• Backspace: delete password characters;
• Esc: return to the network list.

On-screen setup needs a USB keyboard or mouse attached to the device. The password entry shows characters in clear text for on-site verification.

At boot there is a ~30-second grace period before the setup view appears, so brief offline moments don't trigger it. Saved layouts and numbers survive offline periods; once reconnected, the system leaves the setup view and returns to the publishing display automatically.

Address Changes and Fixed Addresses

After a Wi-Fi switch the device may get a new IP from the router:

• the old address may stop working immediately;
• the screen shows the new address;
• the web page announces the new address and redirects after 5 seconds;
• update browser bookmarks and other devices' addresses.

The current version offers no static-IP entry in the management page. The recommended approach is a DHCP reservation on the router (binding a fixed IP to the device's MAC) so it always gets the same address. If the site truly requires static IP, gateway or DNS settings, contact the supplier or the network administrator.
