Touch panels connect using Cat 5, Power over Ethernet

Jan. 18, 2012
The TLP 710 series touch panels from Extron Electronics accepts S-video or composite video signals over Category 5 cabling.

The new TLP 710 series seven-inch touch panels from Extron Electronics incorporate Power over Ethernet capability and feature twisted-pair receivers that accept either S-video or composite video signals over Category 5 cabling. Extron points out that these features provide integration flexibility and aid in cable management by minimizing the number of connections.

One model, the TLP 710MV, mounts on a wall, lectern or other flat surface. The TLP 710TV is designed to sit on a tabletop or install on a VESA mount. And the TLP 710CV is a flip-up 7-inch touch panel that can be mounted to a tabletop, lectern or other flat surface.

Each panel in the TLP 710 series works in conjunction with any of Extron's IP Link control processors. The company says they are designed for use in AV system applications that require complete, interactive control of conferencing systems, displays, switchers and source devices. The touch panels and IP Link control processors communicate using a standard Ethernet network.

Delivering AV applications over Internet Protocol (IP) communications systems, such as Ethernet, is becoming an increasingly attractive option, according to some. Keith Kazmer, global product manager with Black Box Network Services, recently wrote about this trend.

"AV-over-IP appliances allow users to combine multiple types of content, including video with scrolling text, photos, Flash, and Web content," he explained. "Signage displays in retail settings can present merchandise in full AVI, QuickTime, or MPEG video formats, while also showing text descriptions and Web site content for online purchasing. In the smartphone era, consumers expect immediate information through dynamically displayed content. Digital signage can incorporate multimedia that mirrors a smartphone or tablet by presenting fresh content that holds the customer's attention.

"Implementation of AV over IP does not typically require new cabling installation, as firms can often use existing LAN infrastructure," Kazmer continued. "Duplicate wiring very often exists next to the current setup that carries the business's Internet bandwidth loads. Using this redundant wiring can provide enhanced range and allow businesses to send over very large compressed video and image signals without any worry about interruption of other business processes."
