For use with or pulled from: (for reference only) Used to transmit data bit-by-bit between 2 devices, typically a computer (DTE, Data Terminal Equipment) and a modem or printer (DCE Data Communication Equipment). A DB9 Female to DB25 Male cable is primarily used to bridge the physical gap between two different generations of RS232 serial interfaces, a modern computer (9-pin port) to a legacy peripheral device (25-pin port) like AT Modem, Industrial PLCs (Programmable Logic Controllers), CNC machines, serial printers; barcode scanners; and specialized lab equipment such as DNA sequencers. Many DB9 to DB25 adapters (cables) are designed for 3-wire (Transmit, Receive, Ground) or 7-wire communication. In these case Pin 1 DCD and Pin 9 RI signals are ignored because they are not part of the core data exchange. Simple RS-232 or Basic RS-232 usually refers to an adapter (cable) missing pins 1 and 9 categorized as a Partial RS-232 or 7-Wire RS-232. Not all 9-pin (DB9) to 25-pin (DB25) Serial Cables are interchangeable. They may looked identical on the outside but their internal wiring is often fundamentally different to suit specific tasks. Using the wrong cable will result in a 'no connection' error or, in rare industrial cases, could potentially damage sensitive equipment.
