Products Description
A USB-to-Null Modem RS232 serial cable is a cable used to connect a computer to a serial device. The PCM-KW-479 features a USB connector at one end and a DB9 connector at the other. Serial devices-such as modems, printers, and various other peripherals-typically utilize the RS232 protocol for communication. Modern computers, however, are generally no longer equipped with RS232 serial ports, having instead transitioned to USB interfaces. Consequently, the USB-to-Null Modem RS232 serial cable serves as an adapter, enabling you to connect to RS232 serial devices via a USB port. The term "Null Modem" signifies that the cable's pin configuration has been specially arranged to facilitate direct communication between two devices, thereby eliminating the need for an intermediary modem.
