Your LitUp wall is driven by a NovaStar TB2-4G controller. You never program the controller box directly — you send content and settings to it from free NovaStar software. This guide splits into two paths: pick the one you’re using with the PC / Phone switch at the top right, and swap any time.
ViPlex Express (Windows) — the full tool for building and publishing content. Best for designing layouts. Download from NovaStar’s website.
ViPlex Handy (iOS & Android app) — handles everyday publishing, brightness and on/off from your pocket. Get it from the App Store or Google Play.
Your device and the controller need to be on the same network, and you’ll need your sign’s pixel size (width × height) once. The rest of the manual follows the path you choose above.
Content travels from your device, across the network, into the controller — which plays it on the wall on its own.
The TB2-4G runs in async mode: once you publish, the content is copied onto the controller and stored there. You can close the app, shut the laptop, and the sign keeps playing what you sent. You only reconnect when you want to change something — and you can do that from either a PC or a phone.
You rarely touch the box once it’s installed — but here’s what each connection does.
The ETHERNET port carries data to your LED display and connects the controller to your network — leave it plugged in. The SWITCH powers the unit on and off. HDMI IN takes a live video source, USB 2.0 loads content from a U-disk, and the SIM CARD slot is for optional 4G. Two antennas handle Wi-Fi and 4G (COM), and the PWR/CLOUD and SYS/RUN lights show it’s powered and running. On the other side of the unit you’ll find the 12V power input, a RESET button, and an audio output — and a label with the Wi-Fi name and password.
There’s a small reset button on the controller. Hold it for about a minute to restart it; the password returns to the factory default SN2008@+. Change it back to your own afterward.
Do this once at the start of every session.
Everything you display is bundled into a “solution” — a playlist of images, videos and text. Build it, then publish it.
Publishing always overwrites what’s on the wall — that’s the key idea.
Open the solution, delete or replace the image / video / page, then publish again. The new version replaces the old one.
Publish a simple holding page (black, or a logo). To tidy your library, select an old solution and click Delete.
Deleting a solution inside the software doesn’t change what’s on the wall. Only publishing changes what the sign shows.
With a light sensor fitted, the sign dims at dusk and brightens at midday — easier on the eyes at night and on your power bill.
A good baseline — nudge to taste once you see the sign in real conditions:
| Setting | Start | What it controls |
|---|---|---|
| Max screen brightness | 100% | Brightest the sign goes (full daylight) |
| Min screen brightness | 10% | Night floor — dim but still readable |
| Max ambient | ~15,000 | Reading that counts as “full daylight” |
| Min ambient | ~500 | Reading that counts as “night” |
If the table includes a 0% step, the sign can dim all the way to black. Remove the 0% step to hold a minimum glow, then Apply.
You can still dim on a clock. In Smart mode, add time slots — e.g. 100% during the day and a lower value overnight, repeating daily.
Do this once at the start of every session.
AP + the last 8 digits of the serial number; the default password is 12345678 — both are printed on a label on the controller. The first time you join, open your phone’s settings for this network and turn Auto-Join OFF. (Or put your phone on the same wired/Wi-Fi network as the controller.)The controller only lets one phone onto its Wi-Fi at a time. If its network isn’t showing up, another phone is almost certainly still connected — make sure nobody else is connected and it’ll reappear. This is exactly why you turn Auto-Join off in step 1: it stops your own phone from silently grabbing and holding the connection the next time you walk up.
On the phone you build the same kind of “solution” — a playlist — then publish it.
Publishing always overwrites what’s on the wall — that’s the key idea.
Open the solution, remove or replace the media or page, then publish again. The new version replaces the old one.
On the solution list, slide the solution to the left to delete it. To clear the wall, publish a black or logo holding page.
Deleting a solution in the app doesn’t change what’s on the wall. Only publishing changes what the sign shows.

Confirm you’re on the same network, then refresh. A grey dot means offline — check power and the network cable.
The controller allows just one phone on its Wi-Fi at a time. If its network isn’t listed, another phone is still connected — make sure nobody else is connected and it reappears. Turning off Auto-Join keeps your phone from holding it.
You probably edited but didn’t re-publish. Publish again and wait for it to finish.
The solution resolution doesn’t match the wall. Rebuild the solution at the correct pixel size.
Lower the min screen brightness, or remove low steps from the mapping table. Make sure it’s on Smart, not Manual.
Check power first. After a power cut the controller restarts and resumes the stored content on its own; if it doesn’t, reconnect and re-publish your solution.
