RS485-FL-DPLX-EVM is a board and kit that functions as a full-duplex physical layer for communication between two nodes in a network. The board has two Transmit and Receive sections, each of which sends or receives a fully-differential signal on the respective pins. It also includes termination resistors and signal switches for easy and versatile signal handling.

One of the primary applications of this board is embedded industrial control systems. RS485-FL-DPLX-EVM allows these networks to communicate through their GPIOs for a wider range of control and command operations. The board can also be used to implement additional features such as monitoring, system diagnostics, security, or home automation. Additionally, this board and kit can serve as a communication link in large-scale control systems.

The working principle behind the RS485-FL-DPLX-EVM is rather simple. The board receives and transmits differential signals on the respective pins. Each pair of pins form a signal path, and when the signals are transmitted, they are balanced at the receiver end. This ensures that any changes in the signal strength, due to environmental noise, is minimized.

The signal is then routed through different sections of the board. The receive section processes it and does a bit by bit byte conversion before sending it to the control unit, while the transmit section handles the serialization process before sending it to the transmitting device. The signal is then propagated on to the next node. The board also includes a pull-up resistors to ensure that the signal is received and processed properly and a squelch circuit to reduce false signals.

The RS485-FL-DPLX-EVM has also proven its utility in robotics applications. It can be used to command and control robots through a wide variety of distributed networks. By deploying an RS485 network with two-way communication, the robots can be effectively monitored and controlled. In addition, the board and kit can take care of basic diagnosis and maintenance functions, thus significantly reducing the time and costs associated with fixed node maintenance.

The main advantage of using the RS485-FL-DPLX-EVM is its simplicity. The boards are available in either surface mount or plug-in type configurations. Installation is rather easy, and all that is required is a soldering station and a set of common tools. Moreover, by only requiring two pins to be connected to the network, the board also provides a flexible solution for distributing a signal over the network.

In summary, RS485-FL-DPLX-EVM is a highly versatile evaluation and demonstration board that is often used in a variety of different applications ranging from robotic to industrial control systems. The board has two transmit and receive sections which allow it to receive and transmit a full-duplex, electronically balanced signal. Additionally, the board includes termination resistors and other signal handling features to ensure reliable data transmission over the network.
