VW5-LM121Transmitter

User manual There are two keys on the product, which each of them is pressed can generate a serial of digital code with the carrier at modulator stage by way of FSK mode and to the transmitter antenna. And of course there are different from each other in key value. What is more,every time we press any of the key will generate a different serial of digital code comparing with the former time, and it varies according to some rules. Acorrding to the designation,the carrier frequency is defined at 433MHZ and at a specified fundamental frequency +5KHZ or -5KHZ. Antenna is printed in PCB The transmitter is powered by 12V Battary. Main function description The product is used for controlling the opening and closing of a door. Up key Down key There are two keys on the product which marked up key an down key. Up key is defined to open door and the down key is defined to close the door. If we need open the door ,we can press the up key.on the contrary ,we press the down key.
