Application
-
Communication port
The most widespread use of D-subs cable is for RS-232 serial communications, although the standard does not mandate this db 9pin cable. RS-232 devices initially used DB25 pins, but the less common signals were omitted for many applications, allowing DB9 pins, female cable, and male cable to be used.
Many uninterruptible power supply units have D sub 9pin cables to send signals to a connected computer via an RS-232 interface. These typically do not send data serially to the computer, but instead use handshake control lines to indicate low battery, power failure, or other conditions. However, this use is not standardized among D-sub cable manufacturers and may require special cables.

Network port
db9 cables are used in some Token Ring networks and other computer networks. DB9 connector is usually used for CAN: DB9 female connection cable.
The connector is on the bus, and the db9 to db9 cable is on the device.
