Supports low-level RS485 as well as Modbus RTU master/slave
Modbus RTU implementation standard-compliant for all read/write functions of coils and registers
Supports half and full duplex
Configurable baud rate, parity, stop bits and word length
Switchable 120 ohm termination
With the RS485 Bricklet, Bricks can receive and send differential data via RS-485.
It supports half and full duplex and has 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 Modbus-compliant. In Modbus RTU Master mode, any coils/registers can be read and set by a slave. In Modbus RTU slave mode, data can be provided for coils/registers and received via a Modbus master write operation.
The Bricklet has no galvanic separation 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. If this leads to unwanted connections, ground loops or short-circuits in the respective application, the use together with an insulator Bricklet is advisable.
The RS485 Bricklet has a 7-pin Bricklet connector and is connected to a brick with a 7p-10p Bricklet cable.
Power consumption: 64mW (12.8mA at 5V, idle)
Baud rate: 100 - 2000000 baud
parity: None / odd / even
stop bits: 1 / 2
word length: 5 / 6 / 7 / 8
duplex: Half / full
