Unlike ordinary ASK or OOK transmitter, which only has one frequency, also known as frequency where peak transmitting power is achieved. FSK transmitter has two frequencies, one lower frequency and one slightly higher frequency. In hardware programming such as Si4010 chip, the frequency set is actually the higher frequency – not the center frequency, which …

Today since many transmitting frequencies are standardized in most countries, and some frequency such as 433.92MHz and 315MHz are very popular in most countries, while this is a good thing about standardization, but it also means you will more likely to experience signal interference. Signal interference may happen in some countries where 433.92MHz is used …

By default, and feasible in most circumstances, we use a fixed power supply either 12V or 24V to provide the power to our receiver, so we seldom consider the ratings etc. In this article we will give you a rough idea how much power will our receiver consume. The following technical specifications are measured using …

Hello after one month, finally today we can say the development of ATA PTX-5 compatible remote is nearly completed, around 90 percent. In this new remote, we will keep the feature just same as original remote, with all buttons and remote learning function enabled through a combination key for example 3+4. Soon we will be …

As you can see on our wireless relay boards like SR-RCS-202U and SR-RCS-204U, the terminals of relay output is always marked as N/O N/C COM etc, they are abbreviations that are commonly used with relays, here are what they means. N/O means Normally Open ( to COM output ) N/C means Normally Closed ( to …

DHL tracking – http://www.dhl.com.hk/en.html FedEx tracking – http://www.fedex.com/us/track/ UPS …

Basically the most common seens batteries used in RF remote control are two types, alkaline battery and lithium battery, and there are two types of alkaline battery, one larger battery that is 12V 23A and the other smaller battery which is 12V 27A. if you’re using lithium battery, commonly we use one CR2032 coin battery …

Motors are used everywhere to move objects forward and reverse, such as in garage and gate openers, curtains etc. thus many customers use our two channel receiver SR-RCS-202U’s built in function to control DC motors forward and reverse. While it should be simple in most circumstances, sometimes you may experience shorter remote range or un-responsive …
