Ethernet TCP/IP LED Sign Communication

Ethernet is a wired communication method allowing an Ethernet communication card (installed in your computer) to communicate with the LED display over a Local Area Network (LAN) or a Wide Area Network (WAN). TCP/IP over Ethernet network is another term used for this. Ethernet is a very fast communication method. In simple terms, a movie file can be transferred to a LED sign in under a minute versus 15 to 20 minutes using RS232.
When should I use it?
  • Ethernet Network is already available (LAN or WAN).
  • High speed connection is desired for sending Movie files or large picture files to the LED sign quickly.
  • Need access to the LED sign from several computers or from a company wide network.
  • Distance from the LED sign to the Computer or Network switch is less than 300 feet.
Benefits:
  • Cable is inexpensive 
  • Ethernet networks are common
  • Multiple signs can be controlled from single network
  • Files load quickly to sign.
Considerations:
  • Installer should be familiar with computer networks to link the network to the signs IP address.
  • Recommended for distances less that 300 feet
  • Will need to be able to run a CAT5 cable between the sign and network connection. The may be obstacles in the way such as sidewalks or parking lots.
  • Recommended method for sending movie, picture or large data files due to its fast speed.
