Products > Adapters > Serial Adapters (DB9/DB25)

Adapter and converter from both the DB9 (9pin) and DB25 (25pin) RS-232 serial standards with our extensive line of adapters. Our ANGLE adapters allow for serial connectors in tight locations.

In computing, a serial port is a serial communication interface through which information transfers in or out sequentially one bit at a time. This is in contrast to a parallel port, which communicates multiple bits simultaneously in parallel. Throughout most of the history of personal computers, data has been transferred through serial ports to devices such as modems, terminals, various peripherals, and directly between computers.

Most modern desktop computers no longer support serial connections - but this technology - invented by IBM - continues to be used in business and industrial environments supporting printers, scales, and other point-of-sale (POS) devices.
