Information being transferred between data processing equipment and peripherals is in the form of digital data which is transmitted in either a serial or parallel mode. Parallel communications are used mainly for connections between test instruments or computers and printers, while serial is often used between computers
3 easy steps to understand and control your RS232 devices. This article will explain the following topics in details: 1) Step 1: Understand RS232 Connection and Signals 2) Step 2: Learn about the Protocol 3) Step 3: Control your RS232 devices by using 232Analyzer. After reading this page, you should be able to
12 Nov 2008 RS232 is a asynchronous serial communication protocol widely used in computers and digital systems. It is called asynchronous because there is no separate synchronizing clock signal as there are in other serial protocols like SPI and I2C. The protocol is such that it automatically synchronize itself. We can
18 Feb 2011 RS232 Serial Interface Standard. ?. A “Space" (logic 0) will be between 3 and 25 volts. ?. A “ Mark" (logic 1) will be between -3 and -25 volts. ?. The region between 3 & -3 volts is undefined. ?. Maximum data rates may be up to 20 kbps. ?. The reason to study RS-232C is that the serial part (Com port) found in
you'll probably notice throughout this tutorial). The clock-less serial protocol we'll be discussing in this tutorial is widely used in embedded electronics. If you're looking to add a GPS module, Bluetooth, XBee's, serial LCDs, or many other external devices to your project, you'll probably need to whip out some serial-fu.
