Opto Isolated USB to RS485 FTDI Interface Converter
Written by kmtronic
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 tranceiver, so you can have up to 32 devices on the bus.
