Common RF remote control switch / RF relay board can be chosen from either of 3 working modes:  Momentary, Latched or Toggle. These 3 working modes are either by using different 2272 decoder ICs (2272-M4 for Momentary, 2272-L4 for Latched, 2272-T4 for Toggle) or using our programmable smart RF relay board (using Jumpers and MCUs). Short …

Super regeneration is based on an oscillator in on / off operating mode. When it is switched on, the oscillation phase is preceded by a short period of very high sensitivity. The time required for oscillation to begin is then a function of the external energy input to the oscillator (detection of an incident carrier). …

Here we picked some commony asked questions by customers, regarding RF remote control transmitters and receivers, and we hope it will help our customer choose the suitable product, thanks. 1. Can multiple remote control transmitters be used nearby to each other? Many times designers assume that because a transmitter has a unique address code or …

Here we write down some frequently asked questions regarding FCC ID test and certificate, hope it will help customer in FCC testing process. 1. How much does FCC certificate test cost? This depends on how much you have the test lab do. Full transmitter and receiver testing can cost around $5,000, transmitter only around $3,500, …

Thanks for online sources, we have put together related topic and summarized the difference between RF and IR remote controls, as follows. Infrared has traditionally been the first choice for most home entertainment remotes, like TV and air conditioner remotes, because of its ease of use and low cost solutions. However, with the integration of …

Follow-up on previous post, we have prepared the sample and send 1pcs working sample to testing labs on Jun 27th, 2014 and the testing labs received sample on Jun 28th, 2014. The testing labs checked the sample and confirmed it would work fine in following test, the test sample is 1pcs 315Mhz remote control transmitter …

Today we received a customer enquiry, asking if our default remote control transmitter can be hard-wired to be integrated into other system, the detail listed as follows. Customer ask, can the transmitter / remote control be hard-wired for intergation with another system? such as a honeywell fault signal, not sure if this is pulsed, or …

For non-standard development projects, which requires software customization, we always recommend customer to write a document summary, describing all the requirements, especially for more complex receiver customization projects. The contents of requirement document can be concise and logical, so our engineer can easily understand the whole system logic, and program correct software in short time. …

We will send 1pcs sample to our testing labs after finished prototype design, it is the most important for labs testing, but aside from working sample, we also need to prepare several documents as requirement by testing labs, as follows. Circuit description, this is a short description of how the transmitter or receiver works, including …
