This opto/galvanic isolated auto transmit converter, features bi-directional serial conversion from USB to RS485 in 2 wire half duplex mode using Virtual Serial COM Port.
The USB-RS485 is a complete, self powered, USB to RS485 Interface working at any baud rate up to 250k baud. It features automatic bus turn-around - any time your not transmitting the module is listening.
Uses the SN75176 transceiver, so you can have up to 32 devices on the bus.
The Modbus industrial protocol was developed in 1979 to make communication possible between automation devices.
