What is an RS232 used for?
RS-232 is an interface for the interchange of serial binary data between two devices. It is a standard protocol used for serial communication; it is used for connecting a computer and its peripheral devices to allow serial data exchange between them.
Is RS232 used today?
While USB has become the standard, RS232 is still widely used for older printers in the workplace. The RS232 protocol and cable allow the computer to give commands to the printer via a voltage signal. The printer then deciphers those commands and completes the print.
What are the features of RS232?
RS232 Features and Specifications RS232 uses Asynchronous communication so no clock is shared between PC and MODEM. Logic ‘1’ on pin is stated by voltage of range ‘-15V to -3V’ and Logic ‘0’ on pin is stated by voltage of range ‘+3V to +15V’. The logic has wide voltage range giving convenience for user.
Is RS232 a VGA?
But I’m curious because you say that the connectors look “exactly like VGA ports.” Usually RS232 utilizes a DB9 (DE9 for the educated and/or purist) with is the same size as a VGA (HD15) but has only 9 pins in two rows instead of 15 pins in three rows.
Is RS-232 a VGA?
Is RS232 the same as VGA cable?
Registered. No they’re not video ports they’re controler port for conecting a computer rs 232 or other controler to the projector to control certain functions of the projector.
Can I convert RS232 to Ethernet?
Serial to Ethernet Converter is an electronic appliance or a specialized software which converts RS232, RS485 or RS422 serial data signals to Ethernet. Both software and hardware Serial to Ethernet Adapters works in the same way.
What is the difference between Ethernet and RS232?
The main difference between RJ45 and RS232 is RJ45 has a small port as compared to the RS232 port. RJ45 is used as a connector in Ethernet networks, but RS232 is used in serial connections. RJ45 supports 8 pins, but RS232 supports 9 pins. RJ45 is used as an interface, but RS232 is used in industrial applications.
