Communicating in comfort
As mentioned, CMS software for LED-based EMCs allows businesses to create, schedule and update their own messages. It can also let them diagnose any new problems remotely, from the comfort of their offices.
Overall, CMS packages are becoming easier to use. They are increasingly becoming cloud-based, so their various functions—from content creation to diagnostics—can be accomplished from any Internet-connected device, even a mobile phone.
Of course, this also means the sign needs an Internet connection. The most popular communications technologies for this purpose are radios, fibre optic cables and broadband wireless connectivity.
Radio communications systems offer a wireless point-to-point option for signs. They are especially effective at long ranges of 305 m (1,000 ft) or more. Some models feature frequency agility, which enables a radio to detect any interference and automatically optimize the security of its signals.
Fibre optic cabling can provide a fast, reliable communications infrastructure for digital signage. Indeed, it is usually necessary if a sign is to display live video feeds. The cabling is run through a fibre adapter box, installed within a 38-mm (1.5-in.) conduit. This is often the same conduit used for power lines.
A broadband wireless high-speed Internet connection offers many convenient benefits to sign owners. All information is transmitted and received via cellular modem, providing a secure connection. Not only can businesses troubleshoot and update their signs from other Internet-connected devices using cloud-based software, but they will also find managing content for networks of multiple signs becomes easier.

Intelligent installations
There are some basic considerations to keep in mind when installing LED-based EMCs as part of an overall sign project. For these purposes, sign companies should work closely with EMC manufacturers.
One of the most important is to understand all of the installation and operation costs associated with the sign. EMCs offer the benefit of continuous advertising because they are capable of operating 24-7 and year-round, but there are expenses involved in such operation that need to be budgeted for before the purchase.
On a similar note, the energy efficiency of large-scale LED arrays has improved significantly over the past five years. So, if an older sign is to be replaced by a new sign of approximately the same size, then the business should find itself drawing substantially less electricity and, thus, paying lower power bills in the future.
Most EMC manufacturers offer information about installation requirements upfront, but in case they don’t, it will be important to ask them the right questions:
Businesses enjoy stronger sales after installing on-premise EMC’s.
1. How is the sign vented?
As with any other electronic device, the power drawn to run an EMC will generate some heat. To ensure continuous operations, the sign needs to be engineered to dissipate this heat to keep its electronic components cool. Ventilation considerations will affect the overall sign design and installation.
2. How should the sign be stored and lifted?
The manufacturer may need to provide additional recommendations with regard to storing and then lifting the sign into place, as part of the overall installation procedures.
3. What are the mounting requirements?
Both to ensure structural longevity in the field and to maintain the conditions for warranty coverage, it is very important for the installer to follow the manufacturer’s guidelines for securely mounting the EMC in place.
4. What is the startup procedure?
The sign company should become familiar with the CMS software to help its customer power up the sign for the first time and begin feeding content to the screen.
When the time comes to install the sign, there are also a few basic safety guidelines to remember. It is essential to install an electrical disconnect for the main power source and to turn off the power before servicing the sign. Proper grounding and electrical installation procedures, as referenced in the manufacturer’s installation manual, should always be followed, along with the applicable local building and electrical codes. Sign equipment should never be serviced under wet conditions. And personal protective equipment (PPE) must always be properly worn when working at heights.
Sign shops that are new to the EMC market should be sure to work with knowledgeable, experienced installers. Their input and help will save a lot of time and trouble, both upfront and down the road, and make for much happier customers.
