Digital Display Technology
Digital Display TechnologyPower Over Ethernet is a technology that integrates data, voice and power over a standard ethernet infrastructure. The concept has been around for some time but was only recently formally approved as an international standard - IEEE standard 802.3af. Now established as an economical, safe power distribution method, we’re beginning to realize its practical applications across industry. Devices such as IP telephones, wireless LAN access points, clocks and surveillance cameras can receive power as well as data over existing CAT5 cabling.
The versatility of this new technology is only limited by the imagination of system designers. So imagine this rolling out an installation of shelf edge digital signage players is no picnic, how much simpler would it be if you could get 15.4 watts of power (at 48 volts) over the same twisted pair cable that already delivers your store communications. This, of course, must be undertaken by a qualified electrician whereas laying out additional Cat 5 cabling can be handled by the IT Department.
Blue Chip Technology, a leading UK innovator and manufacturer of single board computers, data acquisition modules and industrial computer systems, quickly identified PoE as the perfect add-on feature to its prototype media player known as gondolaPLAY, developed in conjunction with Screenplay Communication Ltd.
Based on Blue Chip’s own 1GHz ETX embedded computer, the core board combines a strong multimedia performance with low power management, making the system a viable candidate for Power over Ethernet. The unit includes a 7” LCD, 10/100 ethernet, USB, audio and 20Gbit hard drive, all in a compact aluminium chassis W160mm x H40mm x D225mm.
Using this type of embedded PoE enabled player, you only have one set of wires to bring to a display - simplifying installation and saving space. It’s also a safer set up with no mains voltages anywhere. The display can be easily moved, to wherever you can lay a LAN cable with minimal disruption to the goods display area.
As well as the data transfer to and from the appliance, you can use SNMP network management infrastructure to monitor and control the displays auditing your digital signage real estate. A SNMP manageable centralised power source enhances the protection against power overloads, outages, surges and spikes. When PoE is implemented, along with uninterruptible power supplies (UPSs) or battery backups, it allows enterprises to distribute power even when the AC electrical power is down.
