USB NMC-2.5M (FTDI)

The USB NMC-2.5M is an USB to USB Null Modem Cable 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 The RS232 port has almost entirely been replaced by the USB port. 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 FT232R USB to Serial UART IC and handles all the USB signalling and protocols. 2.5m cable which supports data transfer rate up to 3Mbaud at TTL levels.
