Description / RS485 Bricklet
The RS485 Bricklet can be used to extend the features of Bricks by the capability to send and receive differential data with RS-485.
It supports full- and half-duplex and has configurable termination.
You can use the Bricklet in RS485, Modbus RTU master and Modbus RTU slave mode.
In RS485 mode you can send and receive arbitrary data. The Modbus modes are fully Modbus compliant. In Modbus RTU master mode you can write and read any coils/registers from a slave. In Modbus RTU slave mode you can provide data for coil/register reads and you receive the data that a Modbus master writes to the coils/registers.
This Bricklet ist not galvanically isolated to the Tinkerforge system. This means that there is a direct electrical connection between the terminals of the Bricklet and the rest of the system. Dependent of the application this can lead to undesired connections, ground loops or short circuits. These problems can be prevented by using the Bricklet together with a Isolator Bricklet.
