Title: the Basic Serial Interface circuit plans This electronic circuit makes connecting a personal computer to the "real world" easy. By using your computer's serial port and a few simple lines of BASIC program, external devices can be monitored and controlled. You can build the BSI using the plans provided on this page. BASIC Serial Interface (BSI) Introduction: Serial Port A D converter Circuits | Electronics Design This circuit is a simple 8 bit analogue to digital converter circuit which is connects to PC serial port. The circuit is based on TLC548 A D converter chip (might be hard to get nowadays, Texas Instruments makes this IC), which is an A D converter with serial output. Serial Port A D converter – Circuit Wiring Diagrams This circuit is a simple 8 bit analogue to digital converter circuit which is connects to PC serial port. The circuit is based on TLC548 A D converter chip (might be hard to get nowadays, Texas Instruments makes this IC), which is an A D converter with serial output. The output of the TLC548 is not switches Connect a micro switch to a PC serial port ... a PC serial port has 3 outputs and 5 inputs. the outputs are TXD, RTS, and DTR, the inputs are CD, RI, RXD, CTS, and DSR. all of the inputs will respond to any voltage over about 1.2V as A high and a voltage less than 0.6V or unconnected as a low. Serial port A virtual serial port is an emulation of the standard serial port. This port is created by software which enable extra serial ports in an operating system without additional hardware installation (such as expansion cards, etc.). It is possible to create a large number of virtual serial ports in a PC. Control Your Electronics through a Parallel Port dummies The parallel port has one advantage over USB ports: It makes it easy to create your own circuits that interface directly with the port. These circuits can control low current devices such as LEDs, or they can activate transistors or even mechanical relays that in turn can activate high current devices such as motors, incandescent lamps, or sound systems. Getting 5v from 9 pins serial port RS232 to power a circuit. Hi, Is it possible to get power of 5v from the 9 pins serial port? I would like to power my circuit which is max232 and RF Transceiver module. I'm planning to make them function without using any external power supply but just to use an excess pin from DB9 and get 5v from there. I'm already using RXD, TXD and GND pins of the 9pins serial port. AVR circuit to PC via COM port using Virtual COM Port Write COM port program on PC (Visual C , Visual Basic) 1. COM port overview. A COM port or Serial Port is a communications port that is part of the "aging" form of the PC, both desktops and laptops. Today, with the emergence and "expansion" of the USB standard, the COM port (and either the LPT port or the parallel port) is disappearing. PC serial port buffer – Circuit Wiring Diagrams The circuit is a simple buffer which adds more driving capacity to PC serial port for the signal to go succesfully from PC computer to terminal server (other direction had no problems). The computer is connected to connector CON1 and the buffered output is available ar CON2. Serial Port Temperature Sensors Serial Hardware Interface The circuit consists of four connections to the PC's serial port, two connections to the temperature sensor, two zener diodes, two Schottky diodes and a resistor. Due to the small number of components, it is possible to build a circuit that is small enough to fit inside a plastic DB9 serial port shell.
