32~65536 grade gray level, support software Gamma correction

Support the rules and special-shaped handle

8 ports output,one port can support 512-1024 lamp pixels

On-line (also can SD Card) control, offline control can be multiple controllers used in combination, the contents of the line control program stored in the SD card

Compatible with single line or double line chips

If the controller to the lamps distance can choose photoelectric isolated transmission and as far as several distances of up to 200-300 meters

Note: the T-300 K controller offline control, each machine controller must put a SD card.

Note: If the distance between controller and lamps more than 50m, we suggest using differential signal transmission control or Photoelectric isolated signal transmission control,please read the manual carefully. Signal lines must be a cable,the best is Super five kinds of cable.


Application scope

LED digital tube, LED point light sourcethe exterior light and a module pixel screen (dazzle colour screens) high power DMX lighting.


Specific parameters

Memory card

Type: SD card, if controlling so many lamps it is best to use the high-speed SD card

Capacity: 128MB-2GB

Format: FAT

Store file: *.led


Physical parameters

Working temperature: -30~85 Celsius

Weight: 1.35KG

Working voltage: AC 85~265V

Working power: 8W

Size: L270mm*W180mm*H55mm

Signal port: 3pin connect port

Note: T-300K Support online download the effect-file to SD card.

Before copy files to SD card,The SD card must be formatted as FAT format.

The SD card in controller can not be hot-swappable, plug the SD card every time, you must first disconnect the power supply


Differential signal transmission control


For many big engineering, the distance between lamps and controller more than 50m and less than 200m.

2 details

built-in Signal transmitter above signal transmission Repeaters,signal transmission receiver



The distance, between controller and transmission Repeaters between transmission Repeaters and transmission Repeaters between transmission Repeaters and signal transmission receiver can not be more than 50m,The maximum distance between controller and signal transmission receiver is 200m


Trouble shooting

Question 1: controller after electrify, indicator light is normal, but the lamps no effect change

Answer: the reasons for this are the following:

(1) Please check lamps signal and controller have correct connection.

(2) If it is meet TTL signal, lamps and lanterns and controller must altogether, namely the lamps GND (ground) to the GND and controller (ground) got together.

(3) Please check the effect file of SD card ,the selected models whether current lamps and used the chip consistent.

Question 2: after power, the T-300k ERROR indicator has been flashing without display output

Answer: the ERROR indicator has been flashing means the controller did not read the card correctly, possible problems:

SD card is empty, with no effect file.

The effect file in the SD card and the controller model are not match, please choose correct controller model in LedEdit and then re-create the effect file *led.

SD card did not format to FAT before copy effect files.

Please check the supply power voltage, the controller can be individually powered to exclude power reasons

Changing the SD card and then test to exclude the possibility of a bad SD card
