RS-232 serial cable pinout diagram @ pinouts May 30, 2017Pinout of Null modem cables and layout of 9 pin D-SUB female connector and 25 pin D-SUB female connectorDE-9 to DE-9, DE-9 to DE-25 cables. Use this cable to connect two devices equipped with serial RS-232 interface. This cable may be used to connect any RS-232 equipped device to computer, connect two computers via COM serial port and so on. Arduino Nano: Pinout, Wiring Diagram and Programming Feb 27, 2021In this post I want to talk about the Arduino Nano: pinout, wiring diagram and programming. What is an Arduino Nano? Arduino Nano is the smallest, typical microcontroller board based on ATmega328P microcontroller made by Atmel. Using Mini-B USB cable: or any other microcontroller. Serial communication is available on digital pins 0 (RX Staircase Wiring circuit diagram & working Apr 07, 2017Staircase wiring is a common multi-way switching or two-way light switching connection; one light two switches wiring. Here one lamp is controlled by two switches from two different positions. That is to operate the load from separate positions such as above or below the staircase, from inside or outside of a room, or as a two-way bed switch, etc. Straight-through, Crossover & Rollover Cable Pinouts Straight-Through refers to cables that have the pin assignments on each end of the cable. In other words, Pin 1 connector A goes to Pin 1 on connector B, Pin 2 to Pin 2, etc. Straight-Through wired cables are most commonly used to connect a host to a client. What is Serial Communication and How it works? [Explained] Nov 25, 2018Microwire is a three wire serial communication protocol. It has a serial I/O port on the microcontroller to interface with peripheral chips. It supports speed up to 3Mbps. It faster than i2c and subset of SPI protocol. Conclusion. Serial Communication is the vital part in the area of Electronics and Embedded Systems. The rate of data transfer USB - Wikipedia Wireless USB is a cable-replacement technology, and uses ultra-wideband wireless technology for data rates of up to 480 Mbit/s. The USB-IF used WiGig Serial Extension v1.2 specification as its initial foundation for the MA-USB specification, and is compliant with SuperSpeed USB (3.0 and 3.1) and Hi-Speed USB (USB 2.0). Serial Connection - Mazda AIO Tweaks Note: The smaller 2x4logic diagram looks like it’s the opposite of the other picture but that’s because the CMU is using 2S to transmit (so the serial adapter will be receiving). For the sake of simplicity, connect the RX port of your Serial Adapter to 2S (top) and TX port to 2T (bottom). Be sure that the cable is going into the port. RS232 serial cable pinout information - Lammert Bies As most of the computers are equipped with the DB9 serial port version, all wiring examples on this website will use that connector as a default. If you want to use the example with a DB25, simply replace the pin numbers of the connector according to the conversion table below. What are Infrared Emitters, Receivers and Repeaters? Block diagram of modulated IR transmission and reception Older remotes with only a single channel used the presence of a carrier signal to engage a function. Later systems with multiple channels (for multiple functions: volume control, change channel, change input type, etc.) modulate the carrier signal with a different frequency for each function. Understanding RS485: Wiring, Connection, Monitoring Jul 07, 2020The wiring requirements can then be relaxed to allow cables to run in star arrangement from the computer and the terminating resistors become optional. Line Pull Ups: Avoiding Serial Errors In many RS485 multidrop systems there are times when no unit is driving the RS485 lines.
