Figure 1.2 – Block diagram of USB Hi-Speed Serial/Hub Module
As the block diagram Figure 1.2 shows, the USB Hi-Speed Serial/Hub Module routes the signals from the
GL850G and FT4232H devices to two 18-pin, 0.1”, single-row headers and a dual-port USB A-type
socket. This allows easy connection to most PCB header sockets and ribbon cables.
To reduce the connector pin count, only channel A and B fan out all the 8 data signals to the 18-pin
header. For the channel C and channel D, since many designs only use the TXD/RXD/CTS/RTS signals in
UART communication, only these 4 data signals are fanned out. This meets most application
requirements.
To use the FT4232H connected to a PC , the FT4232H Hub Module requires specific USB device drivers,
available free from http://www.ftdichip.com. The drivers are used to make the FT4232H on the
Module appear as a four virtual COM ports (VCP). This then allows the user to communicate with the USB
interface via a standard PC serial emulation port (TTY). Another FTDI USB driver, the D2XX driver, can
also be used with application software to directly access the FT4232H on the Mini Module though a DLL.
The main target application for the USB hi-Speed Serial/Hub Module is that it can be attached to the FTDI
VNC2 based V2DIPx modules (there are 6 different sizes) as a expansion module. By connecting the USB
Hi-Speed Serial/Hub Module to the USB socket on the V2DIPx modules, the two modules can work as a
single module to be placed on the bread board. The USB Hi-Speed Serial/Hub Module expands the
interfaces of V2DIPx module with up to 3 USB ports and 4 serial ports. More information is available on
the V2DIPx modules at http://www.ftdichip.com/Products/Modules/DevelopmentModules.htm.
