The USB-to-USB Null Modem Cable is a modern replacement for the traditional serial null modem cable. The traditional null modem cable was used to connect two PCs via their RS232 serial ports, but fewer modern PCs continue to implement the RS232 serial port.
The RS232 port has almost entirely been replaced by the USB port. However, there is still a need to transfer files between PCs that are not networked.
The FTDI USB Null Modem Cable (NMC) solves this problem and allows a user to connect two PCs using their USB ports. The user can then perform file transfers between the PCs via the USB interface.
The NMC cable contains a small internal electronic circuit board encapsulated into the USB connector at both ends of the cable. The electronics is based on the FTDI FT232RQ USB to Serial UART IC and handles all the USB signalling and protocols. The FT232RQ datasheet, DS_FT232R, is available at ftdichip.com.
The NMC cable is a USB powered, USB 2.0 full speed compatible, 2.5m cable which supports data transfer rate up to 3 Mbaud at TTL levels. The NMC cable supports the FTDIChip-ID, with each cable end programmed with a unique USB serial number. This can be used to create security or password protected file transfer between PCs. Further information and examples on this feature are available at ftdichip.com under FTDIChip-ID Projects.
The cable requires USB drivers, available free from ftdichip.com, which are used to make the FT232RQ within the cable ends 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 (TTY). Another FTDI USB driver, the D2XX driver, can also be used with application software to directly access the FT232RQ though a DLL.
