What is an RS 485 connection?
RS-485 is an industrial specification that defines the electrical interface and physical layer for point-to-point communication of electrical devices. The RS-485 standard allows for long cabling distances in electrically noisy environments and can support multiple devices on the same bus.
What is the difference between RS-232 and RS-232C?
Because this adoption date was so long ago, most manufacturers, including National Instruments, have dropped the “C” from the name and simply refer to the protocol as RS-232. In common, modern usage, there is no difference between RS-232 and RS-232C, protocol.
What is an ex link on Samsung TV?
The ExLink port allows serial control of the Samsung TV. For example, turn on/off , changed channels and etc. The ExLink cable has a 3.5mm jack (like a audio headphone cable) on one side and on the other side is an RS-232 interface.
Can you convert RS232 to RS485?
RS232 to RS485 converter provide conversion between serial networks and other media. They can transparently convert RS232 signals to RS485 signals and vice versa without changing the PC’s hardware or software.
What cable is used for RS-232?
DB9 cable
Keep in mind that RS232 is simply a form of serial communications, or a way to transmit data. A standard DB9 cable is probably the most used cable for this application.
What is RS232 V24 interface?
RS232 Serial Interface: V24 1 RS-232 interface basics. The interface is intended to operate over distances of up to 15 metres. 2 Common data transmission rates. Note: speeds up to 19200 bits per second are normally used. 3 RS-232 connections. 4 RS232 signal levels. 5 Lines and their usage. 6 Secondary lines. 7 Grounding.
What is the voltage of the RS-232C connector?
The RS-232C specification does not include a description of the connector to be used. However, the most common type found is the 25 pin D-type connector. The voltage levels are one of the main items in the specification. For RS232 data signals a voltage of between -3V and -25V represents a logic 1.
What is a 3-wire RS-232 connection?
A minimal “3-wire” RS-232 connection consisting only of transmit data, receive data, and ground, is commonly used when the full facilities of RS-232 are not required.
What is RS-232 and TIA-232?
The current version of the standard is TIA-232-F Interface Between Data Terminal Equipment and Data Circuit-Terminating Equipment Employing Serial Binary Data Interchange, issued in 1997. The RS-232 standard had been commonly used in computer serial ports and is still widely used in industrial communication devices.
