Serial Port A serial port is a communication interface used to transmit data between a computer and external devices, such as laser engraving systems, printers, or peripheral equipment. Serial ports enable serial communication, where data is transmitted sequentially, one bit at a time, over a single wire or cable. In laser engraving systems, serial ports are commonly used for connecting computers or control devices to engraving equipment for data transfer, command input, and system control. Serial port configurations may include RS-232, RS-485, or USB-to-serial interfaces, depending on the hardware and communication protocols supported by the engraving system and computer. |
