FR Plug-in Serial Cards
Multi-port serial cards are a piece of hardware used in computer systems to increase the number of serial ports available. These cards, often installed in the PCI or PCIe slot of a computer, allow multiple devices to connect and communicate simultaneously. They are especially useful in industrial settings, where a large number of machinery or equipment need to interface with a single computing system. These cards can support RS232, RS422, or RS485 communications, providing flexibility depending on the specific needs of the network.
