Description:
1.The USB RS485 cables are a family of USB to RS485 levels serial UART converter cables incorporating FT232RQ USB to serial UART interface IC device which handles all the USB signalling and protocols. The cables provide a fast, simple way to connect devices with a RS485 level serial UART interface to USB.

2.Each USB-RS485 cable contains a small internal electronic circuit board, utilising the FT232RQ, which is encapsulated into the USB connector end of the cable.

3.The integrated electronics also include the RS485 level shifter plus Tx and Rx LEDs which give a visual indication of traffic on the cable (if transparent USB connector specified).

4.The other end of the cable is bare, tinned wire ended connections by default, but can be customised using different connectors to support various applications.

5.The USB side of the cable is USB powered and USB 2.0 full speed compatible. Each cable is 1.8m long and supports a data transfer rate up to 3 Mbaud. Each cable supports the FT232R-ID, with a unique USB serial number programmed into the FT232RQ. This feature can be used to create a security or password protected file transfer access using the cable.

6.The USB-RS485 cables require USB drivers, which are used to make the FT232RQ in the cable 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 (for example TTY). Another FT232 USB driver, the D2XX driver, can also be used with application software to directly access the FT232RQ on the cable though a DLL.
