FTDI Chip Development Kit USB-COM485-PLUS1

The USB-COM-PLUS modules provide a simple method of adapting legacy serial devices with RS-232, RS-422 or RS-485 interfaces to modern USB ports.

The USB-COM232-PLUS1 module is a single channel USB to RS-232 communication device. Utilises the FTDI FT232R
The USB-COM232-PLUS2 module is a single USB interface to two independent RS-232 ports, communication device. Utilises the FTDI FT2232H (USB 2.0 Hi-Speed device)
The USB-COM232-PLUS4 module is a single USB interface to four independent RS-232 ports, communication device. Utilises the FTDI FT4232H (USB 2.0 Hi-Speed device)
RS-232 level shifters are included, plus Power/TXD/RXD LEDs

The USB-COM422-PLUS1 module is a single channel USB to RS-422 communication device. Utilises the FTDI FT232R

The FTDI Chip USB-COM485-Plus1 is a USB to RS485 adapter board. It provides a straight-forward way to convert older devices with as RS485 interface to more up-to-date USB ports. The USB-COM485-Plus1 features RS485 level shifters and the FT232R USB-Serial bridge IC which enables the conversion.

There are 3 LEDs on the USB-COM485-Plus1. A yellow LED indicates when the board is configured and ready. A green LED represents TxD activity when the data is transmitted to the RS485. Finally, there is a red LED which is for the same but with RxD activity.
