TX-R3208 Universal receiving card

product description

Features

32 sets of RGB data output, 32 scans with a maximum load of 256×512 pixels.
Support point-by-point brightness and chromaticity correction, brightness correction up to 256*384 pixels, chromaticity correction up to 128*128 pixels, maximize the elimination of color difference, and improve the color consistency of the LED display screen.
Support module rotation control function, the module can be rotated 90°, 180°, 270° for installation.
All components are arranged on the front side, and there are no components on the back side, which reduces EMI radiation and helps users simplify EMC design.
Support LED modules with MCU or embedded smart chip. Support module Flash to store calibration data, and automatically read module calibration data when power on. Supports high-level grayscale display.
Support temperature, humidity, voltage and network cable connection status measurement and monitoring. Support LCD module.
The dual network ports can be optionally used as signal input for automatic identification.
With a self-test button, it can complete the self-test of red, green, blue, white, single-color grayscale transition, horizontal line, vertical line, and oblique line. Automatically exit the self-test state when a signal input is detected. When multiple cards are cascaded, you only need to press the self-test button on the first card, and then all subsequent cards can enter the self-test state.
Support ordinary constant current source chips, high refresh dual latch chips, and various built-in PWM function chips.
There are various shift clocks, gray levels, and refresh frequencies to choose from.
Ordinary constant current chips have a unique UPWM function, which can make ordinary universal constant current source chips achieve a high refresh rate and richer color performance.
Support any scanning mode within 32 lines. Unit modules that support various snapshot methods. Through the wiring setting of the screen body, it can cooperate with the display unit board of any wiring method.
Support serial decoding circuit, used for unit board modules with more than 32 scans.
Support the red, green and blue serial transmission mode of the light bar screen.
Support dual power backup detection and return.
Support parameter curing and recovery, project file saving and recovery.
Support LEDID one-key restore function.

indicator light

● There are two indicator lights on the R3208. The red indicator light is the power indicator. When the power supply is normal, the light is always on.

● The green indicator light is the working status indicator. When there is no network connection, the indicator light is off. When the A network port shows normal data, the indicator light flashes rapidly, 3-4 times in about 1 second. When the A network port has no display data and the B network port displays normal data, the indicator light flashes slowly, 2-3 times in about 1 second.

● There is a self-test button on the R3208. When the network port is not connected, press the self-test button, and the LED screen will display red, green, blue, white, horizontal lines, vertical lines, oblique lines, and grayscale transitions in sequence Red, green, blue, etc. At this time, the green indicator light is in the state of pressing the button to light up, and then pressing the button to turn off.
