 FAQ For LED screen/display controller and software

• Q: What are the synchronous and asynchronous system?
• A:  If the medium is synchronous, then the interaction that occurs takes place in real time. It means the LED display can show the same thing that appears on PC monitor. We have synchronous controller such as LINSN,COLORLIGHT,DBSTAR Delayed, or asynchronous, communication is any transfer of information that is stored or archived and then later accessed. You can store the information into SD card or other storage media. Then take PC away, the program can play automatically. We normally use LYTEC for asynchronous controller.
• 2 Q: What is the maximum distance between data sending card (or PC) to data receiving card ?
• A:  CAT-5 cable ≤140m
  multi-mode fiber ≤500 m
  single-mode fiber ≤10000 m
• 3 Q: Do you have wireless control system? How to operate?
• A: Yes, wireless control is always available when the network supports. You can choose GPRS, CDMA or other communication method.  Wireless data sending and receiving equipment are needed. Please see the connecting diagram.

• 4 Q: Can laptop computer control the display? How to connect?
• A:  Yes. If the laptop computer has DVI interface, then the connection is the same with desktop PC. Otherwise, you need converters to convert VGA signal into DVI.

• 7 Q: What is the difference between Internal data sending card & Outside data sending card ?
• A: There are two installation methods about the data sending card: one is installed inside the PC—(called internal sending card); another is installed in one box---(called external sending card).
  
  
• 8 Q: How to connect Video Processor with other equipment ?
• A: 
  
  
  Please pay attention to the standby UTP interface. This can only receive the signal, and the first UTP interface can both receive and send the signal.
