Cisco Cisco Digital Media Player 4300G 安装指南

A feature of Cisco Digital Signs can detect automatically when some display brands and models are turned 
On or Off. To connect one of these displays to your DMP, you must use a null RS-232 serial cable in addition to the video 
signal cable. Cisco Digital Signs documentation on Cisco.com explains how to use this feature in your network.

Topics in this section teach you about these presentation systems, signal cables, and adapters.

We certify that DMPs work as designed with Cisco LCD flat-screen displays. All displays in this series 
are engineered for intensive use in public settings. See 

.

In most cases, DMPs can use displays that comply with modern, international standards. We recommend 
the following if you use a third-party display.

 Digital signs and public IPTV installations run many more 

hours each day than a consumer-grade display is engineered to run. A consumer-grade system is 
likely to fail years sooner than a professional-grade system would under these conditions.

 Digital signage uses static images more often than it uses full-motion video. Most 

often, content is web-based or animated in Flash. The nature of these media types means that some 
pixels are not updated frequently in digital signage. LCDs are less susceptible to burn-in than plasma 
displays are. Even though image persistence is sometimes a problem on LCD displays, it is almost 
always self-correcting and is unlikely to occur when you follow manufacturer guidelines for 
managing your displays correctly.

 This recommendation is important in direct proportion to the 

number of displays that you will manage.
