PCBA assembly learning code receiver module 1. Tiny dimension 2. Decode:2272/2240/1527/2240 3. 4 routes output 4. T4/M4/L4

Model No.: DL-R99B

Description: PCBA assembly: tiny learning code receiver module 

Product Detail:

DL-R99B is a multi-function super heterodyne receiver module with MCU decode IC, It can decode fixed code 2262, 2264, learning code 1527, 2240 and most of the fixed code and learning code IC in the market. There are 3 different control modes of toggle(PT2272-L4), momentary(PT2272-M4), interlock(PT2272-T4) through different position of the jumper. It is a very tiny size receiver module with the feature of stable performance, wide applications.

Learning code Instruction

  a. Learn the code: press the learning button on the receiver, release when there is a flash on LED, now the receiver module has entered the learning mode, press any button of the remote, LED on the receiver module will flash 2 times, means the code has been learnt successfully. It will exit the learning mode automatically if there is no any demand for 5 seconds.

  b. Remove the code: keep pressing the learn button for about 4 seconds, LED will flash 3 times, means all the code in the receive module has been removed successfully
