What is DB9 pinout?
Below is the pinout of a typical standard male 9-pin RS232 connector, this connector type is also referred to as a DB9 connector. A computer’s serial COM port (DTE) is usually a male port as shown below, and any peripheral devices you connect to this port usually has a female connector (DCE).
What pins for serial communication?
Serial communication devices make use of 9 or 25 pin D-type connectors for their cabled connections. They are commonly designated as DB-9 or DB-25 with the number used to differentiate between the pin counts. Various manufacturers’ names may replace the DB in the specifications.
How many wires are in a DB9 cable?
Why are there 9 pins but only 5 wires? One of the wires is unshielded. Why is that? The other wires are red, brown, orange, and black.
What is DB9 serial port?
DB9 connectors are designed to work with the EIA/TIA 232 serial interface standard, which determined the function of all nine pins as a standard, so that multiple companies could design them into their products. DB9 connectors were commonly used for serial peripheral devices like keyboards, mice, joysticks, etc.
What is a 9 pin serial port?
DB9 Serial Ports This 9-pin layout become a de facto hardware standard that enabled device manufacturers to create products that worked on a wide range of computer platforms.
What is the 9 pin serial port?
What is a 9 pin connector called?
DB9 connector, a common type of electrical connector. The term “DB9” refers to a common connector type, one of the D-Subminiature or D-Sub types of connectors. DB9 has the smallest “footprint” of the D-Subminiature connectors, and houses 9 pins (for the male connector) or 9 holes (for the female connector).
Can wiring DB9?
It covers wiring for the common DB9 plug and socket often used with CAN bus test equipment….CAN Bus 9-pin D-Sub (DB9) Pinout Table.

| 3 | Optional CAN ground |
| 4 | Reserved |
Why DB9 connector is used?
DB9 is a commonly known connector used in Serial Asynchronous Data Transmission that are are designed to work with the EIA/TIA 232 serial interface standard. RS-232 (Recommended Standard 232) is the standard for establishing serial data transfer between DTE (Data Terminal Equipment) and DCE (Data Circuit-terminating Equipment).
What is a 9 pin serial?
A 9 pin serial port is a communication port and CANNOT be used for a monitor. VGA is 15 pins and 15 pins only.
What is a 9 pin connector?
9 pin mini-din male connector. This is the DIN connector, a member of a family of circular connectors that were initially standardized by Deutsches Institut fur Normung (DIN) for analog audio signals.
