About This Product
■LFA9U is a DMX<->USB (USB2.0 standard compliant) bridge board equipped with the Renesas DMX unit built-in CPU RX631 (R5F5631), and has the following features.
・With our pre-installed application, you can access the DMX communication line with simple commands from the USB HOST device without any knowledge of DMX.
- By using the separately sold CPU debug board, it is also possible to program customer-specific applications.
・With the insulation mounting option, it is possible to electrically isolate the DMX line and this board.
- The board size is small, 2cm x 6.2cm, and can be directly attached to a PC's USB connector.
■What is DMX 512?
``DMX 512'', commonly known as ``DMX'', is a communication protocol used to adjust the intensity of light from lamps, send information on the position, movement, and shape of lighting such as moving heads, and control lighting and stage effects. A standard that defines the communication method between a controller that sends control signals and equipment (devices) that respond to those signals.
It supports up to 512 channels, and channel numbers are determined for DMX compatible equipment. In order to respond to situations that cannot be handled with conventional analog signals, the United States Institute of Theater Technology (USITT) began development in 1986, standardized it as DMX512-A in 1990, and passed ANSI E1.11 in 2004. Approved as USITT DMX512–A.
Currently, lighting control using DMX512 signals is the most common method worldwide. The physical layer is RS485, a start/stop 2-bit start/stop synchronous serial with a transfer rate of 250 kbps, and a maximum of 513 byte packets can be continuously transferred at one time. Since each channel is 1 byte, a value between 0 and 255 can be specified for each channel. The beginning of a channel is indicated by outputting a break signal of 88uSec or more at the beginning of one packet.
