Understanding Gate Opener Transmitters: How They Work and Which One You Need
Transmitters are devices that are used to operate a gate opener system wirelessly, typically with the push of a button. Using a gate opener transmitter provides incredible convenience of being able to open or close the gate from a distance. For example, if you are approaching the gate to your house or ranch, the gate can be triggered remotely without ever needing to leave your vehicle. In more commercial settings, which are common applications for Magnetic AutoControl units, the automatic barriers can be operated from a booth or by someone stationed nearby.
How Does a Remote Transmitter Work?
These types of transmitters emit a radio frequency signal when one of the buttons is pushed. The signal is then picked up by the receiver module within the gate opener control board, which then triggers the motor to move the gate. Before being able to remotely control a barrier gate opener, the transmitter needs to be programmed to the gate opener. Magnetic AutoControl transmitter remotes that feature multiple buttons can have a different function assigned to each one, so different gate openers can be operated from the same transmitter.
Programming the transmitter involves working with the control module of your gate opener. This is done by assigning open or closed functions to different buttons after successfully pairing a transmitter to the receiver. A radio module, (receiver), is the key for these transmitters to successfully 'tell' the gate when it needs to open or close. 100 different hand transmitters can be used on just one radio module when different codes are utilized. Setting the codes for gate opener transmitters and receivers is done by using DIP switches that are located in the transmitter housing itself.
All of the transmitters that are offered by Magnetic AutoControl are operated under FCC ID QV2-SMD-53200TX. The FCC stands for the Federal Communications Commission, which is an independent organization in the United States Government that regulates wireless communications such as radio, television, wire, internet, satellite, etc. Knowing your transmitter is FCC certified will give you the peace of mind that your device has been tested and approved to operate safely and legally within U.S. radio frequency, and the transmission it gives off will be secure.
