    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 data 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.Read More

    There are two types of wireless remote transmitters: electromagnetic waves and infrared. The working distance of the infrared remote transmitter is short, and the infrared ray can only be transmitted through the straight line, and can’t bypass the barrier. RF remote transmitter uses the RF signal, it is transmitted in all directions, and the signal can cross a certain barrier. The electromagnetic wave wireless remote control system uses the transmitting end to transmit the electromagnetic wave, and the receiver extracts the electromagnetic wave, and triggers various devices. Electromagnetic wave wireless remote control system commonly used in burglar alarm equipment, industrial equipment, doors and windows remote control, car remote control.Read More

    The Wireless remote control system consists of two parts: transmitter and receiver. The transmitter mainly includes the coding circuit and the transmitting circuit. The coding circuit first generates a control instruction and then transfers the instruction signal to the transmitting circuit. The transmitting circuit loads the instruction signal on the high frequency signal, and then sends out the wireless signal by the transmitting antenna. The receiver is composed of a receiving circuit and a decoding circuit. Receiving circuit first amplifies the weak signal received, and then sent to the demodulator, the demodulators identify the signal, and then the amplifier circuit drives various devices.Read More

    We have a client who has an airstrip with AC220V runway lighting on the runway and a DC12V solar windsock light. The runway lights are 1000 meters away from the customer's building and the solar lights are 150 meters away from the runway lights. When the plane landed, he needs to turn on both the runway lights and the solar windsock light at the same time.Read More

    One of our clients owns a shop. In the daily operation, it is necessary to maintain public safety, so he installed a security alarm system in his shop, equipped with wireless magnetic detectors, wireless infrared detectors and wireless fire detector. When these detectors are triggered, the warning horn that connects to the warning system will sound the alarm at the same time. After the shop is closed in the evening, he usually will go home and enjoy the rest time. The shop is about 800 meters away from his home. In case there is any unexpected situation in the shop, such as breaking into a thief or a fire alarm, the warning horn in the shop will be triggered. But because the shop was too far from his home, he could not hear the alarm sound, which would delay the best time to take remedial action. So, the client contacted us, also told us about his worry. He wanted us to figure out a wireless solution to install a wireless system. The reason is that he paved a line from the shop to the home is not realistic, and he would like to install an warning horn at home, when the shop warning host is triggered, the home warning horn will ring simultaneously. He told us that his alarm host had a normally open contact output. When the alarm host was triggered, the normally open contact output would be closed.Read More
