Tinkerforge RS485 Bricklet

With the RS485 Bricklet, Bricks can receive and send differential data via RS-485. It supports half-duplex and full-duplex communication and features configurable termination. The Bricklet has three modes: RS485, Modbus RTU Master, and Modbus RTU Slave. In RS485 mode, any data can be received and sent. The Modbus modes are compliant with the Modbus standard. In Modbus RTU Master mode, any coils/registers can be read and set from a slave. In Modbus RTU Slave mode, it is possible to provide data for coils/registers and receive it via a Modbus Master write operation. The Bricklet does not have galvanic isolation from the Tinkerforge system, meaning there is a direct electrical connection between the terminals of the Bricklet and the rest of the system. If this could lead to unwanted connections, ground loops, or short circuits in a specific application, using it together with an Isolator Bricklet is advisable. The RS485 Bricklet has a 7-pin Bricklet connector and is connected to a Brick using a 7p-10p Bricklet cable.
