Can you convert RS-232 to USB?

Another method of connecting RS232 devices to a USB based host is to use a USB to RS232 converter. These devices connect to the host computer USB port via a USB cable and provide a DB25 or DB9 serial port for use with RS232 devices.

Which pins on the DB9 connector are for 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.

What is the use of 9 pin serial port?

DB9 connectors were commonly used for serial peripheral devices like keyboards, mice, joysticks, etc. Also they are used on DB9 cable assemblies for data connectivity. Today, the DB9 has mostly been replaced by more modern interfaces such as USB, PS/2, Firewire, and others.

Can you convert USB to serial?

Commonly, USB adapters are used to convert USB data to standard serial port data and vice versa. Most commonly the USB data signals are converted to either RS232, RS485, RS422, or TTL-level UART serial data. The older serial RS423 protocol is rarely used any more, so USB to RS423 adapters are less common.

What are the two pins that must be connected for RS-232 communication?

Wiring a Rs232 interface The Ground pins must be connected together. Keep in mind that a 25 pin RS-232 port on a PC trasmits on pin 2 and receives on pin 3, and Ground is pin 7. A 9-pin RS-232 port on a PC transmits on pin 3, receives on pin 2 and Ground is pin 5.

What is the use of DB9 connector?

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 are DB9 connectors?

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).

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.
