    People also ask
    How does an RS232 splitter work?
    A Modem Splitter is used to split the RS232 lines so that both gateways can be connected at the same time. The Splitter has diodes to separate the signals and make sure each port doesn't interfere with the signals on the others ports.

    Can RS232 be parallel?
    The RS-232 protocol

    Parallel communications are used mainly for connections between test instruments or computers and printers, while serial is often used between computers and other peripherals. Rs232 protocol transmission involves the sending of data one bit at a time, over a single communications line.

    Is RS232 still relevant today?
    It remained in widespread use into the late 1990s. In personal computer peripherals, it has largely been supplanted by other interface standards, such as USB. RS-232 is still used to connect older designs of peripherals, industrial equipment (such as PLCs), console ports, and special purpose equipment.

    What is the difference between RS232 and DB9?
    Let's break it down: RS232 isn't a gadget or a physical thing, it's a communication protocol. Basically, it's a rulebook for how devices send data to each other. On the flip side, DB9 is a connector—the physical plug that links two devices together using that protocol.Jun 4, 2025
