1. SPI LED Controller Brief Introduction
ST803TC works online or offline and switch automatically.
When it’s offline, it reads data from SD card to control slave controllers and synchronized with AC power supply.
When it's online, port1 transmit data that port2 received from "LED Studio Software". When software stops sending data, ST803TC can detect it automatically, and read data from SD card and send it instantly.
Auxiliary slave controller is ST801RA and ST801RC, auxiliary online software is “LED Studio software”, auxiliary offline software is “LED Build Software”.
(1).Works online or offline and switches automatically.
(2).Drives maximum 170000 pixels, 2 output ports, connects maximum 255 slave controllers.
(3).When it’s offline, multiple master controllers synchronize with AC power supply, achieves controlling hundreds of thousands to millions pixels.
(4).SD card supports FAT32, FAT16 format. The maximum capacity is 64G bytes.
(5).ST803TC can connect to DMX console, supports encryption on number of power-on times.
(6).Supports single file playback and all files playback. Playing speed adjustable range is 1-100 frames per second, brightness adjustable range is 0-15.
(7).Transmit signal based on Ethernet protocol. The nominal transmission distance is 100 meters and it can reach to more than 25 kilometers by using a photoelectric converter.
(8).Electrical isolation and high anti-interference ability.
(9).Flexible engineering configuration, each slave controller can control different lamps.
3.SPI LED Controller Operation Instructions
(1). LCD screen can display model of controller and setting information.
(2). SD card must be formatted into FAT16 or FAT32. SDHC (high capacity SD card) is supported. DAT file in SD card is played based on the file name in alphabetical order
(3). After self-check passed, the first row in the screen displays model of controller
(4). When port2 of ST803TC is used as input interface, it could connect to computer、digital switch、photoelectric converter or other controllers’ output interface, and the parameters of Net2StartNo are effecting port1, the value of data of slave controller that less than the parameters will be shielded off. The slave controller behind will be renumbered from number 1. ST803TC can retransmit maximum 239 data from slave controller, using this point, we can use digital switch to accomplish multiple ports output, please refer to the Network and Optical fiber connecting diagram. For example: We can set 40 slave controllers in computer, send data to switch, connect switch to 4 ST803TCs and connect each ST803TC to 10 slave controllers. The data that switch output is consistent with computer’s. We can set Net2StartN．to 1 for the first ST803TC, set 11 for the second one, set 21 for the third one and set 31 for the fourth one. Then, each slave controller connected to ST803TC is corresponding to each slave controller we set in computer.
(5). Port1 of ST803TC can only be used as output port and it can output to switch、photoelectric converter and slave controller. Port2 can only output to slave controller when it’s used as output interface, but it can connect to photoelectric converter through IP converter. Cross cable must be used when ST803TC is connected to computer.

5. Network and optical fiber connection diagram
(1).Work offline. (Blue line is network cable)
(2).Work online, ST803TC transmit data from computer to slave controller, if there is no data sent from computer, ST803TC will read data from SD card and send it to slave controller automatically.
(3).Use switch to output to multiple network interfaces, the following picture illustrates the process: computer’s wireless network card send data to wireless switch, and then transmit data to ST803TC, you can also use the cable network card to send data, data is received by several ST803TCs, the following picture only draws four ST803TC receivers, you can use more according to actual needs.
(4).SPI LED controller using optical fiber to acquire further transmission distance. If slave control to slave control requires the use of optical fiber, you need to add a IP converter, the use of specific methods please refer to the slave control instructions.
