Code setting and modification of C series transmitter

The C Series is the most commonly used transmitter with many advantages.It is compact which means easy to carry, and with a sliding cover to prevent misuse of the button. We provide single-button transmitter, 2 button transmitter, 3 button transmitter and 4 button transmitter, as shown in figure:


C series transmitter has a fixed code and learning code two types. The fixed code transmitter needs to be set by Soldering iron. Learning code transmitter can be used directly.Fixed code transmitter usually use PT2262 or SC2262 encoding chip, we generally use 8-bit address code and 4-digit date code. The total capacity of address code has 6561 group. The address code is set by pins 1 ~ 8 of PT2262 or SC2262. These 8 pins can be set to three states: floating, grounding and connecting to the positive power supply. These three states represent codes 0, 1 and 2, respectively. So the address code consists of 0, 1 and 2, such as 00210210 or 12212001.

The setting and modification method of the address code is as follows:

Open the transmitter case and you will see the circuit board. There is a row of chip pins (A0~ A8) on the back of the circuit board and two rows of pads. The top one is marked “H” and the next one is marked “L”, as shown in figure:


If the chip pin is soldered to the “L” end, it represents code 1. If the chip pin is soldered to the “H” end, it represents code 2. If the chip pin is not soldered, it represents code 0. This 8 – bit code is D1 D2 D3 D4 D5 D6 D7 D8 in the right – to – left the order, as shown in figure:


If you want to set up the code 10021002, the welding method is as follows:

Do not weld the pin D2, D3, D6, D7. They stand for code 0.

Welding pins D1 and D 5 to “L”, they represent code 1. 3. Welding pin D4 and D8 to “H” ends, and they represent code 2.



In the process of use, if the transmitter’s working range is getting shorter, the LED indicator light is getting darker.

Please replace the battery of the transmitter.


If you pull out the transmitter ‘s telescopic antenna, The transmitter’s working distance will be farther.
