This article is about the RS-232, standard. For RS-232 variants, including the common 9-pin connector, see serial port. A DB-25 connector as described in the RS-232 standard Data circuit-terminating equipment (DCE) and data terminal equipment (DTE) network
USB RS232 Cable Series - FTDI
UART – 1200 – 12M Baud, Fast mode (FM), I2C - standard mode (SM), Fast mode plus (FM+), High Speed mode (HS) No method is specified for sending power to a device. While a small amount of current can be extracted from the DTR and RTS lines, this is only suitable for low-power devices such as mice. The standard does not define a maximum cable length, but instead defines the maximum capacitance that a compliant drive circuit must tolerate. A widely used rule of thumb indicates that cables more than 15m (50ft) long will have too much capacitance, unless special cables are used. By using low-capacitance cables, communication can be maintained over larger distances up to about 300m (1,000ft). [13] For longer distances, other signal standards, such as RS-422, are better suited for higher speeds.

(January 2000). "TIA/EIA-422-B Overview" (PDF). Application Note 1031. National Semiconductor. Archived from the original (PDF) on 2010-01-06 . Retrieved 2011-07-28. The standard has been renamed several times during its history as the sponsoring organization changed its name, and has been variously known as EIA RS-232, EIA 232, and, most recently as TIA 232. The standard continued to be revised and updated by the Electronic Industries Association and since 1988 by the Telecommunications Industry Association (TIA). [6] Revision C was issued in a document dated August 1969. Revision D was issued in 1986. The current revision is TIA-232-F Interface Between Data Terminal Equipment and Data Circuit-Terminating Equipment Employing Serial Binary Data Interchange, issued in 1997. Changes since Revision C have been in timing and details intended to improve harmonization with the CCITT standard ITU-T/CCITT V.24 [ de], but equipment built to the current standard will interoperate with older versions.

The US232R-500 is FTDI's premium USB to RS232 evaluation cable which can be used for testing the functionality of the FT232R device and drivers prior to design-in. The EIA-232 standard specifies connections for several features that are not used in most implementations. Their use requires 25-pin connectors and cables.Use Windows Update to install the latest drivers on your PC. Below is how to perform USB to RS232 drivers through Windows Update: RS-232 adds the legacy voltage values to the binary values (0/1 or hi/lo, or "mark" and "space" in RS-232 talk). A TTL UART will output (and input) only TTL levels, essentially 0 bit = 0V and 1 bit = 5V. And many modern-day gadgets (Arduino, et.al.) simply use TTL voltage levels for serial communication. But the "proper" definition of RS-232 used a rather HIGHER and BIPOLAR voltages to define zero and one. Specifically: On an external modem the status of the Ring Indicator pin is often coupled to the "AA" (auto answer) light, which flashes if the RI signal has detected a ring. The asserted RI signal follows the ringing pattern closely, which can permit software to detect distinctive ring patterns.

How to download the USB to RS232 Driver?
Because both ends of the RS-232 circuit depend on the ground pin being zero volts, problems will occur when connecting machinery and computers where the voltage between the ground pin on one end, and the ground pin on the other is not zero. This may also cause a hazardous ground loop. Use of a common ground limits RS-232 to applications with relatively short cables. If the two devices are far enough apart or on separate power systems, the local ground connections at either end of the cable will have differing voltages; this difference will reduce the noise margin of the signals. Balanced, differential serial connections such as RS-422 or RS-485 can tolerate larger ground voltage differences because of the differential signaling. [12] In the book PC 97 Hardware Design Guide, [9] Microsoft deprecated support for the RS-232 compatible serial port of the original IBM PC design. Today, RS-232 has mostly been replaced in personal computers by USB for local communications. Advantages compared to RS-232 are that USB is faster, uses lower voltages, and has connectors that are simpler to connect and use. Disadvantages of USB compared to RS-232 are that USB is far less immune to electromagnetic interference (EMI) [ dubious – discuss] and that maximum cable length defined by standards is much shorter (15 meters for RS-232 versus 3–5 meters for USB, depending on the USB version and use of active cables). RS-232 cable lengths of 2000 meters are possible with appropriate line drivers. [10] [11] Digispark Attiny85: Easily save space using this tiny chip to replace an Uno.
