A wireless serial RF (Radio Frequency) radio is a good solution if you need to communicate with a RS232 serial device over a long distance. This radio will allow you to communicate serial data over a range of up to 1600 feet. It is a good, simple and reliable low-cost solution without any advanced functions so it is very simple and easy to setup and use.
These radios works as transceivers, meaning each radio can transmit and receive, but not at the same time.
They can be setup to communicate in point-to-point or point-to-multipoint networks. Each radio has 12 channels which means you can have up to 12 pairs of radios at the same location communicating at the same time without they interfere with each other. See our setup examples for how the radios can be configured in a network or point-to-point.
The parameters of the radios must be configured over the serial RS232 interface which is a standard DB9 female connector. If your computer does not have a serial COM port, we highly recommend using a good quality USB to RS232 serial converter such as this USB to serial adapter which is fully compatible with these radios.
Power to the serial wireless radios is provided through the included USB cable. In case you don't have a USB port available we also offer a 110VAC/5VDC adapter which can be used for powering the radios if you have a 110VAC outlet available instead. With each serial wireless radio is a USB to DC adapter cable included, which will allow you to connect the 110VAC/5VDC power adapter to the USB connector.
The simplicity and reliability of these serial wireless radios makes them an ideal solution for many applications and environments such as factory automation, building control, CNC machinery and many other applications.
These radios are sold individually. To setup a communication link you will need two radios.
The radios broadcasts in the unlicensed 433Mhz band so no license is required.
