The FT232BM is the 2nd generation of FTDI's popular USB UART device and the FT232BL is a lead free version of it. RoHS
New high Speed USB 2.0 RS232 9 Pin adaptor. Allows you to connect devices which use an RS232 connector to your PC or Laptop via USB and take advantage of the high speeds that USB 2.0 offers.
Uses the highly regarded FTDI Chipset. This USB Serial Adapter provides instant connectivity with modems, ISDN TAs, PDS, handheld & pocket PCs, digital cameras, POS, serial printers, etc. It is suitable for remote access, retail and industrial applications, data collection and other applications requiring a High speed and or LOW serial communications port.
Changing the COM Port Number is relatively easy - From DeviceManager, select "View devices by type", then "Ports (COM & LPT)". Select the USB serial port and click Properties. Select the "Port Settings" tab, then click Advanced. Choose the required COM port number from the list and click OK. Notes If a modem is attached to the USB serial port when the port number is changed, it will continue to work under the new port number.
This device not only adds extra functionality to its predecessor (FT8U232AM) and reduces external component count, but also maintains a high degree of pin compatibility with the original making it easy to upgrade or cost reduce existing designs as well as increasing the potential for using this device in new application areas.
