Neo Universal 4-Port Multiport Serial Adapter |
Multiport serial adapters, also known as multiport serial cards or serial expansion cards, are peripheral devices used to add multiple serial ports to a computer system. These adapters typically connect to the computer's motherboard via a PCI or PCIe slot and provide additional serial ports for connecting serial devices such as modems, printers, and barcode scanners. Multiport serial adapters are commonly used in industrial automation, telecommunications, and point-of-sale systems where multiple serial devices need to be connected to a single computer.
