Flex-Sky-Link-RS485 Wireless Data Receiver
The Flex-Sky-Link-RS485 serves as a data receiver designed for Nokeval Ovasky’s 433 MHz wireless data transmission technology. Its primary function is to receive and store the data packets transmitted by Ovasky transmitters.
Housed within a rugged and watertight (IP 66) plastic enclosure, it’s further protected by two rubber O-rings sealing the joint between modules. The receiver operates on an 8 to 30 VDC power supply and connects to a computer or PLC through RS-485.
Data transmission between the receiver and the computer is facilitated using the Nokeval SCL or Modbus RTU protocol. The Flex-Sky-Link-RS485 is equipped with a single diagnostic LED for status indication.

What is a Data Receiver?
A data receiver is a device or component that captures and interprets data transmitted wirelessly or via a network. It receives and processes data signals, making the information accessible for further use, analysis, or storage by connected systems or devices. Data receivers are commonly used in communication systems, IoT devices, and various data collection applications.
What is Wireless Data Transmission?
Wireless data transmission refers to the process of sending digital information between devices without the use of physical cables. It utilises wireless communication technologies, such as radio waves, Wi-Fi, Bluetooth, or cellular networks, to transmit data over the airwaves.
