Product Details

USB to RS-232/RS-422/RS-485 Converter PCB, FTDI Chip

These USB to RS-232 / RS-422 / RS-485 converters provide a fast and simple method to convert serial UART to USB. The USB connector contains a small circuit board featuring the FTDI FT232RQ (RS 730-0168) serial UART interface IC to handle all the USB signalling and protocols. There are two LEDs to indicate data being received and transmitted.

The RS-232 has a maximum UART Baud Rate of 1 Mbaud while the RS-422 and RS-485 both have a maximum of 3 Mbaud.

These converters are supported with Microsoft WHQL certified VCP drivers for Windows, Apple Mac, and Linux. All of which are available, royalty-free from FTDI website. http://www.ftdichip.com

FTDI Chip Interface Board

The FTDI Chip interface board is a USB to RS422 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 and simple way to connect devices with an RS422 interface to a USB. Each module contains a small internal electronic circuit board, utilising the FT232R plus a USB Type-A connector. The board requires USB drivers which are used to make the FT232R on the PCB appear as a virtual COM port (VCP). This then allows the user to communicate with the USB interface via a standard PC serial emulation port.
These converters are supported with Microsoft WHQL certified VCP drivers for Windows, Apple Mac, and Linux.
