Wiring Instructions
A simple guide to connect all cables and accessories to your sign.
Setting up your new LED sign might sound technical, but no stress — the cables are designed to only fit where they belong, and this guide walks you through each connection one step at a time. By the end of this page, your sign will be fully wired, connected to Wi-Fi, and automatically adjusting its own brightness. Let's get to it.
How to Wire Multi-Row LED Signs
Know Your Ports: A Quick Overview
Before you begin, locate the four main connection points on the back of your main sign cabinet:
Sensor Port
Top right corner (4-pin connection).
Antenna Port
Just below the sensor port (RJ45/Ethernet connection).
Power Port
Top left side (3-pin connection).
Signal Port
Bottom left side.
Install the Brightness Sensor
The brightness sensor automatically adjusts your sign's display based on ambient light — brighter in daylight, dimmer at night — to maximize visibility and save energy.
- 1.Locate the 4-pin Sensor Port in the top right corner of the main sign section's back panel.
- 2.Align the 4-pin connector on the sensor cable with the port — it only fits one way — and press in until it clicks.
- 3.Mount the sensor itself on the front face or top edge of the sign so it has a clear, unobstructed view of the sky. Avoid mounting it behind the sign or under a roof overhang.
- 4.The sensor is plug-and-play. It requires no additional software configuration and will activate automatically once you power on the sign in Step 5.
Connect to Wi-Fi or 4G Network
The network antenna lets you control your sign remotely from a phone, tablet, or computer. Follow these steps to connect it to your on-site Wi-Fi.
- 1.Locate the Antenna Port on the main sign section — it sits just below the Sensor Port on the back panel.
- 2.Take the antenna cable (RJ45/Ethernet end) and plug it firmly into the Antenna Port. You'll hear a click when it's seated.
- 3.Thread the weatherproof end of the cable outside the cabinet and screw the antenna onto it hand-tight. Point the antenna upward for best signal.
- 4.Once your sign is fully powered on in Step 5, you will follow the Network Setup guide to connect the antenna to your Wi-Fi network using the Viplex app.

Route the Signal Cables
Here's how to wire the signal cables and turn all the LED modules into one big digital screen.
- 1.Locate the main section — the one that houses the antenna and sensor.
- 2.Connect one end of a signal cable to 'Signal 1' on the main section.
- 3.Connect the other end to 'Signal 2' on the first secondary section.
- 4.For larger signs, continue the pattern: Signal 2 of one section → Signal 1 of the next.
Power Cables: Choosing the Right Method
For Smaller Signs (Daisy Chain)
- 1.Plug one end of the first power cable into your main power source (junction box).
- 2.Connect a second cable from an output on the first powered section to the input on the next section.
For Larger Signs (More than 20 amps — Individual Cables)
- 1.Each sign section gets its own power cable.
- 2.Route the other end of each cable to your junction box or main power source.
- 3.Ensure all connections are secure and properly insulated.
- 4.Power on and check each section to ensure the sensors and network connections are active.
110V Connection
- •Brown/Black – Hot / Live
- •Blue/White – Neutral
- •Yellow & Green / Green – Ground
220V Connection
- •Brown/Black – Hot / Live
- •Blue/White – Second Hot
- •Yellow & Green / Green – Ground
⚠️ Safety Tips
- •Always ensure power is OFF at the main source before connecting or disconnecting cables.
- •Use cables and connectors that meet the electrical requirements and local codes.
- •Label cables and connectors to facilitate easier maintenance.
- •Regularly inspect connections for wear and tear.
