Commissioning Workflow
Hardware Wiring ───> Wi-Fi Hotspot or LAN Connect ───> NovaLCT Screen Config ───> ViPlex Publishing ───> VNNOX Cloud Bind
`
1. Hardware Ingest and Physical Interconnection:
· Mount the TB20 Plus inside the LED cabinet service compartment or onto a DIN rail or wall bracket using the integrated mounting flanges.
· Connect a Cat5e or Cat6 network patch cable from the Ethernet Output Port directly to the first LED receiving card (such as NovaStar DH7508, A5s Plus, or A8s).
· If live synchronous playback is required, connect an HDMI cable from a media laptop or camera to the HDMI 1.3 Input port.
· Connect the 3.5mm stereo audio output to an external PA system or active speakers if audio playback is required.
· Connect an external NovaStar NS048C ambient light sensor to the sensor port to enable dynamic environmental auto-dimming.
· Connect the included DC 12V 2A power adapter to the DC power socket and verify that the red PWR indicator illuminates steadily.
2. Local Control Connection via Wi-Fi Hotspot or Wired LAN:
· The TB20 Plus automatically broadcasts an internal Wi-Fi Access Point (SSID formatted as AP plus the device serial number).
· Connect a commissioning smartphone, iPad, or Windows laptop to the player Wi-Fi hotspot using the default factory password (12345678).
· Alternatively, connect a network cable from the Gigabit LAN Port to an office router with DHCP enabled.
3. NovaLCT Receiving Card Mapping and Cabinet Configuration:
· Launch NovaLCT on a PC connected via USB Type-B or local network.
· Enter advanced administrator credentials (password: admin) and navigate to Screen Configuration.
· Load the validated receiver card configuration file (RCFGX), configure the cabinet coordinate grid across the single Gigabit Ethernet output, and ensure the active pixel load remains strictly within 650,000 pixels.
· Click Send to Hardware and Save to RV Card to solidify cabinet topology in non-volatile flash memory.
4. Local Playlist Publishing via ViPlex Express or ViPlex Handy:
· On a Windows PC, open ViPlex Express (or launch ViPlex Handy on an iOS or Android device).
· The software detects the TB20 Plus automatically over Wi-Fi or LAN.
· Create a multimedia solution: insert 4K video clips, high-resolution still images, scrolling text notices, weather widgets, and analog clocks.
· Publish the solution directly to the TB20 Plus 32GB onboard memory for continuous standalone asynchronous looping.
Frequently Asked Questions
What is the core difference between the TB10 Plus and TB20 Plus?
