This post is the second part of duplicating existing keyfobs – using cloning remote duplicator series. In the previous post, we have explained basic information on how to find the best duplicating position for each cloning keyfob model, the basic principle is to reduce the metal blocking as much as possible. The whole series is …

As you may already noticed, Ditec has two remote models very similar to each other, both model name and the look. Yes they are DITEC GOL4 and GOL4C, but don’t mess one model with the other, since they’re not compatible. Ditec GOL4 is a rolling code remote, which has white LED cover color, while GOL4C …

Accessing garage or gate opener box is sometimes quite bothersome, or you are not able to access …

Antenna Length Table INFORMATION: The table below has listed several common RF transmitter frequencies and their matching antenna length, the best antenna length is calculated by divide the wavelength by four. RF Module External Antenna Length Calculations Operating Frequency Best Antenna Length 315 MHz 23.81 cm / 9.37 inch 418 MHz 17.94 cm / 7.06 …

Overview – Typical RF Remote Control PCB Layout A typical RF remote control’s PCB is comprised of many electronic components, such as SAW resonator which controls the transmitting frequency and encoder IC which encodes the transmitting data. The typical inner photo of RF remote control is listed as follows.   Identify Operating Frequency There are …

There are some basic knowledge that you may use everyday but not noticed. For example, most garage and gate remotes only have one button, so how does the door or gate know if it is to close or open? since the transmitted signal from remotes are the same every time – take fixed code for …
