Application Overview

Significant improvements in electronic display and event-timing systems during the past few years have made signs and scoreboards easier to install, operate, view and maintain. LED displays are providing low power consumption and thousands of hours of operation for indoor applications; reflective digits allow view of signs in direct sunlight in outdoor applications; and portable signs are allowing users to keep score anywhere with battery power.

The biggest recent improvement to the sign and scoreboard market has been the integration of dynamic wireless communications. Wireless connectivity provides hassle-free installation and operations of single or multiple scoreboards within the same facility, indoor or outdoor. And digital spread spectrum data transmission with channel hopping allows for secure, interference-free operations, even with several signs on-site.

When considering multiple scoreboard installation, wireless communication is ideal because it allows users to operate many signs independently as well as in unison. If a customer has an athletic facility where there is more than one sport being played, multipurpose scoreboards can provide scoring, timing and all other necessary information for several sports instantly via remote RF controls. System setup time from one sport to another is fast and simple.

What's more, wireless data collection systems can be designed for both one-way and bi-directional transfers of information, turning scoring displays into convenient portable communication tools between judges or head scorer locations. Dynamic networks enable integration of various systems, allowing auxiliary displays such as shot clocks or additional timers to tie into any network setup. Expansion of existing installations is limitless.

For off-site control, information can be communicated to displays via phone or Internet link using wireless modems and built-in software. Set up is as simple as on-site control: a central PC receives the data on-site, then transmits it from a 'server' base station to the 'client' transceiver at the sign(s). The wireless system can also communicate back to verify successful transmission.

The Benefits of RF

• No expensive, invasive cables
  No need to install data cables or to repair weathered, damaged or vandalized cables in the field.
• Secure data
  FHSS technology, proprietary protocol, and security tools resist meddling and interference from cell phones, pagers, security systems, cordless mics, etc. Error checks and ACKs confirm the integrity of information transmitted from the equipment.
• Co-located networks
  Multiple networks can be located on the same site. FHSS and multiple channels ensure interference immunity between systems.
• Versatility of control devices
  Customers may use their own computers fitted with your system software and a plug-and-play radio, or you can supply custom controls with embedded radios. A single PC can control multiple serial devices simultaneously.
• Power conservation
  Power-saving modes allow for conservative use of battery power as well as AC power to the sign and controlling system.
• Excellent range
  The sign(s) may be set up miles away from the controlling system.
• Fast data transfer rates
  Data rates of up to 115.2 Kbps enable score recording and information flow with no perceived delay.
• Smooth installation and upgrades
  Use of industry-standard interfaces allows for easy installation of wireless into new or existing electronics. Later, systems can easily be upgraded with new equipment, features and functions.
• Global acceptance
  AeroComm's radios can be used virtually worldwide.
