  USB - RS232/422/485 Modules

FTDI supply a range of modules supporting conversion from USB to a range of commonly used serial interfaces such as RS232, RS422, and RS485. Modules are based on the FTDI USB to serial converter ICs and support multiple channels.

 

 

  USB-DUO
The USB-DUO brings together the FT231XS and FT3243S in a single kit for developing USB to RS232 solutions.

The FT231XS is the USB to full handshake UART device from FTDI’s X-series of devices offering low power and low pin count in a 20 pin SSOP package. The UART IO from the FT231XS device is translated to RS232 signal levels via the FT3243S, RS232 transceiver, provided in a 28 pin SSOP package.

The devices may be used with the default FTDI drivers for creating USB to RS232 solutions on all major operating systems such as Windows, Linux, MAC, Android.

 

 

 

 

  DB9-USB Modules
The DB9-USB range of modules provide a simple and fast method of migrating existing DB9 based connector UART interfaces to USB 2.0. In some cases this can be done without the need to redesign the PCB. In some cases they can reduce system costs by removing an RS232 level shifter from a design. The modules feature a USB2.0 mini-B connector within a module which fits a standard 9-pin DB9 connector footprint.

Ideal for legacy applications which feature UART DB9 based connectors, these modules provide a method of extending the life-cycle of these products by converting them to USB2.0 connectivity, with minimal redesign.

The DB9-USB family consist of 6 modules. Two of these operate at RS232 voltage levels – these can be used as a direct replacement, with no PCB changes, in a system which uses RS232 levels, while four of them operate at digital voltage levels (a choice of 5V or 3.3V) – these can be used to interface to an application systems logic level which could result in the bill-of-materials being reduced by the removal of any RS232 level shifters which may be present in the system. Each is available to replace either a male or a female DB9.
