The USB-RS485-PCB is a USB to RS485 level serial UART converter PCB incorporating FTDI‟s FT232RQ USB to Serial UART interface IC device which handles all the USB signalling and protocols. The PCB provides a fast, simple way to connect devices with a RS485 interface to USB. The USB-RS485-PCB contains a small internal electronic circuit board, utilising the FT232R plus a USB type-A connector.The PCB is USB powered and USB 2.0 full speed compatible. Each PCB supports a data transfer rate up to 3 Mbaud and supports the FTDIChip-ID™, with a unique USB serial number programmed into the FT232R. This feature can be used to create a security or password protected file transfer access using the PCB Features: - USB-RS485-PCB provides a USB to RS485 Serial UART interface
- Entire USB protocol handled by the electronics on the PCB
- EIA/TIA-485 interface with low power requirements
- UART interface support for 7 or 8 data bits, 1 or 2 stop bits and odd / even / mark / space / no parity
- Data transfer rates up from 300 baud to 3 Mbaud
- Internal EEPROM with user writeable area
- Support for FT232R FTDIChip-ID™ feature for improved security
- PCB is USB Powered – no external supply required
