What is a RS 232c port used for?
An RS-232 serial port is most often used by repair technicians to perform diagnostics and service updates. It may also be used to control a device when connected to a computer running a home automation system or Custom Integrated Audio/Video (A/V) system, such as the CAV-M1000ES Multi-room A/V Distribution System.
Is RS485 serial?
RS232, RS422, RS423, and RS485 are all essentially physical layer protocols. They are all serial communication protocols and are ubiquitous device interfaces.
Can I use RS485 for RS232?
No. An RS232 Serial Interface is for connecting two devices. There will be one transmitter and one receiver. An RS485 Serial interface can connect up to 32 devices to a single transmitter.
Which COM port is RS232?
RS-232 was commonly used in computers to connect devices like a printer or a telephone modem. In computer terminology the RS-232 connector is often referred to as the “serial port”.
What is RS 232C on a TV?
RS-232 is an advanced and specialized form of installation that allows the TV to be controlled through a cable connected directly to the TV. Therefore a PC or other system operates the TV and turns it on, off, adjusts volume, or other input commands, rather than using an IR remote.
What is a RS 232C cable?
This is a RS232C communication dedicated connector cable that is used to connect computer to computer, control device to control device, or personal computer to control device.
Is RS485 and RS232 the same?
While RS-485 and RS-232 have a lot in common regarding the data format, they differ on a very significant parameter: Where RS-232 specifies single-ended connections referenced to ground, RS-485 specifies differential signaling on two lines, called A and B.
What is RS485 serial communication?
What is RS-485? 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 Rs-485 used for?

What is a RS-232C connector?
RS232 connector is a port used for data exchange between equipments. It was designed for data exchange between DTE (Data Terminal Equipment) or PC and DCE (Data Communication Equipment) or MODEM.
What is a RS-232C input?
RS-232C is the interface that your computer uses to talk to and exchange data with your modem and other serial devices.
What is RS-232C input mini jack?
The RS232 port is for an external control system, other than the remote control. The only available method for using headphones with this device would be to connect a Home Theater System or stereo to the OPTICAL Digital Audio Output jack, and then connect the headphones to that device.
What does RS-232 stand for?
Recommended Standard 232
In telecommunications, RS-232 or Recommended Standard 232 is a standard originally introduced in 1960 for serial communication transmission of data.
What is RS-485 used for?
Is RS485 an Ethernet?
By converting RS485 data signals into Ethernet (TCP or UDP) packets, and vice versa, they enable reliable data transmission to other devices or network server applications. This is accomplished by encapsulating the RS485 data in Ethernet packets in a manner that best fits the type of data being transported.
