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.

Note:
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.

Short Description of Toggle / Momentary / Latched Working Modes

Generally there are three working modes for rf remote controls: toggle, momentary, latched. Toggle mode is used most often. Controlling lamp, for example, press the button of remote, turn on the lamp; press the button again, turn off the lamp. Momentary mode can be set to control rolling blind or rolling door. Press and hold the button of remote, open the blind or door; release the button, close the blind or door. Both toggle and momentary mode are motivated by single relay, which means you can work these two modes with single button remote. As regards the latched mode, it is motivated by relay group. For relay group, only one relay will be on at a time, e.g. press remote button A, relay A will be on, and relay B will be off; press remote button B, relay B will be on, and relay A will be off. To be more specific, when you control the lamp by latched mode, you should prepare at least two buttons remote. Press button A, the lamp is on; press button B, the lamp is off. Online s...

Remote Control Electromagnetic Lock

Image
Electromagnetic lock is a locking device that consists of an electromagnet and an armature plate. The principle behind an electromagnetic lock is the use of electromagnetism to lock a door when energized. Essentially it consists of an electromagnet attracting a conductor with a force large enough to prevent the door from being opened. That is to say, if only we could cut off power supply and make electromagnet force between electromagnet and armature plate to disappear, the door would be opened. Furthermore, we just try to use a direct dc output momentary remote and one button transmitter to cut off electric power to open the door. The following demonstration will show. At first, we prepare material. The wiring When we supply power to electromagnetic lock, electromagnet will attract armature plate through magnetic force. The door is locked. When we press button, the power supply will be cut off. The door is open as soon as electromagnetic lock unlock instantly. What’s more, t...

AC Lamp is Controlled by Customized Delay Time RF Remote Controller

Image
We recommend 1channel 110V~220V customized delay time controller (S1RD-AC220+C-2). At first, it must be set delay time in advance. According to your own actual requirement, you can set delay time you want. e. g. delay time: 20 seconds. You cannot change delay time once it is set. It is applied for controlling lights, motors, fans, electrically operated door/ lock/windows/ blinds/ cars or other appliances with AC 110~240V or DC 0~28V. You can turn on/off device on the receiver with transmitter from any place within reliable distance (theoretical distance 100m), the wireless RF signal can pass through wall, floors, doors and other obstacles. Wiring: Initial state: B, C = Normally Open; A, B = Normally Closed. AC lamp is wired to normally open terminals B&C. And add additional ac power to AC lamp. The delay time is set in advance. It is non-adjustable.   Press button 1: Turn on the relay (connect B and C, disconnect A and B) After ...
