Getting Started

Congratulations on choosing a custom-made LED sign by LED Sign City! Our premium LED signs feature state-of-the-art construction for indoor or outdoor applications, and we have put a tremendous amount of thought and care into the design and execution of your sign.

What's included

Your LED Sign City sign includes cabinets, software, and other components necessary for installing, connecting, programming, and operating the sign. If any items are missing, lost, or damaged, contact us immediately.

Your sign comes with the following components and accessories*:

  • LED Control Box (Controller)
  • 2 CPE/Wi-Fi Antennas (optional)
  • PoE Adapter 
  • Brightness & Temperature Probe with Bracket
  • Power and Signal/Data Cables
  • Hex Keys, Bolts, and Brackets
  • Cabinet Drawings
  • USB Drive containing:
    • Software to program the sign
    • An electronic copy of the software user guide
    • A backup program file
    • TeamViewer software

* Your sign may also come with spare parts, such as extra modules and power cables.

Controller

Your LED sign comes with a control box, which includes the control card that stores the sign’s content and program schedules. The control box has additional connections for the optional CPE/Wi‑Fi antenna and Brightness & Temperature probe.

Brightness & Temperature Probe

The Brightness & Temperature probe detects ambient light, and the sign’s screen adjusts automatically. For example, the screen will be brighter during the day than at night.

Connectors

The signal and power connectors are to be inserted in the ports on the back of the cabinets

Connecting the accessories for the control card.

Repeat steps 2 and 3 for connecting the remaining accessories to the control card.

  1. Connect the power
  2. Link the signal cable
  3. Connect the Antenna
  4. Connect the brightness and Temperature Sensor

System Overview

The sign comes with several cables labeled with tags to assist installation. Your sign can either be connected directly to the computer through a cable or wirelessly through an antenna.

Direct Connection

If your sign did not come with the optional CPE/Wi-Fi antenna for wireless connectivity, use the signal cable provided to connect the control box directly to the ethernet port on your computer

You can connect your sign to your computer using an RJ45 ethernet cable. The default network IP address for the sign is 192.168.1.128, and it can be changed to match your network settings.

Wireless Connection

You can choose between Wi-Fi or cellular for a wireless connection. The Wi-Fi option is similar to LAN, and because there are no wires, you can change the program from up to 500 feet from the sign. The cellular option enables you to monitor and update your program over the internet from your web browser.

For wireless connectivity to your sign:

    1. Use the provided signal cables to connect from the LAN port in the Power over Ethernet (PoE) adapter to the ethernet port on your computer or router.
    2. Connect the PoE adapter to the CPE/Wi-Fi antenna.
    3. Mount the other antenna on the sign, and make sure the antennas are within line of sight.
    4. Plug in the PoE adapter to a 110V AC outlet.

Setting up power

Electrical Requirements

The required electrical service is listed on the nameplate on the sign or the sales order sheet. The current rating on the nameplate applies to the cabinet only. LED signs typically require 120V or 240V single-phase electrical service, with two wires, (one hot leg and one neutral) plus a ground.

Terminal Block Signs

Connect incoming power to the bottom of the terminal block assembly, to the left of the breaker.

  1. Connect the live wire to the open terminal marked “L.”
  2. Connect the neutral wire to the open terminal marked “N.”
  3. Connect the service ground wire to the internal cabinet grounding terminal.

Electrical Code Requirements

This sign is intended to be installed according to the requirements of Articles 250 and 600 of the National Electrical Code and/or other applicable local codes and ordinances, including proper grounding and bonding.

Determining Wire Gauge

If service must run several hundred feet, increase wire size one gauge for every 200 feet. The maximum load is 920 Watts/m2.

Connecting Earth Ground and Power

Proper grounding helps protect equipment from electrical disturbances, such as lightning strikes or unintentional contact with high-voltage lines.

Use this checklist as a high-level guide along with the manual while installing the sign.

Mount Sign

  • Follow local codes for placement and wind-load requirements.
  • Follow the manufacturer’s structural requirements.
  • Follow proper handling instructions.
  • Ensure proper ventilation.
  • Install conduit where needed.
      • Watertight conduit is required for connections to the electrical box.

Install Electrical Elements

  • Refer to amperage and voltage requirements for the sign(s).
  • Route power wires to the terminal block, load center, or disconnect of the sign(s).
    Do NOT turn ON power at this time!
  • Install a grounding rod and connect it to the grounding terminal inside the cabinet(s).

Connect Data Cables and Conduits

  • For multiple sign cabinets, connect data cables from sign-to-sign.
  • Install conduit for exposed data cables.
  • Most signs have outdoor-rated cables that do not require conduit.

Install the Brightness & Temperature Probe

  • Mount the probe and route the cable to the twist-lock connector on the back of the sign.

Install Communication Options

CPE/Wi-Fi Antennas: Install both sign and host antennas for line-of-sight communication.

Broadband Wireless (Optional antenna): Mount the antenna on a metallic surface, pointing toward the sky or ground.
