rs232 crossover

consisting of 1-12 point-to-point connections, with the maximum throughput2-Gbps, with very low end-to-end latency for high-performance computing, especially in supercomputers. I2C (Inter-IntegratedCircuit, an integrated circuit) is initially used by Philips for communication between TV internal components. Currently, it is common in embedded devices to provide wired data interaction, such as LCD driver, DSPAnd is widely used in sensor detection. I2C uses two wires to connect the device. One is

site collects pressure, traffic, and other data through the data collection module. It is connected to the GPRS transparent data transmission terminal through the RS232 (RS485) interface and has no standard communication interface, we can also use the gprs rtu with the functions of collecting analog quantities and switch quantities. The embedded processor is embedded in the GPRS transparent data transmission terminal to process the data, encapsulate

following:Only the Fast Ethernet hybrid network module can support these two wan interface cards.The network modules supporting these two interface cards are as follows:NM-1FE2W, NM-2FE2W, NM-1FE1R2W, NM-2W.The Ethernet hybrid network module does not support the following features:NM-1E2W, NM-2E2W, NM1E1R2W.2.

Use of serial port debugging Genie and serial port program debugging skills Time: 19:04:49 | [ 51 single-chip microcomputer has a full-duplex serial communication port. Therefore, the single-chip microcomputer and the computer can communicate with each other conveniently. For serial communication, certain conditions must be met. For example, the serial port of a computer is RS232 level, while th

Remote Process Explorer (binaries only) Windows CE Remote Process explorer currently supports Windows CE 4.x/ 5.0 and x86 and arm architectures (V4 and v4i ). Due to the continuous improvement, the current version may be faulty in some places. If you encounter a problem in use, it may be my fault. For details, see: Powerful Tool for revealing the running status of Windows CE 4. Windows CE 5.0 for VMware For the creation of BSP, see: How to Create a Windows ce bsp supporting Vmware Here we

Recently, a data center solution based on grps dtu data transmission needs to be developed, so I found some materials. I personally think it is very useful. Gprs dtu stands for the GPRS data transmission unit. CurrentlyDTU has a more explicit Convention: gprs dtu is specifically usedSerial Port DataPassGPRSNetworkThe GPRS wireless device for transmission. Four core functions of gprs dtu: 1) internal integration of TCP/IP protocol stack: gprs dtu encapsulates the PPP dialing protocol and TCP/IP p

First: http://www.chenxin.org/BO.HTMThe system hardware consists of two parts:A module consisting of a single-chip Bluetooth chip, flash memory (used to store the Host Control Protocol Stack firmware, etc.), a crystal oscillator and an antenna (which has been welded to the motherboard ). A motherboard, including host I/O and man/machine interfaces (including RS232 and USB drives, audio codecs, external audio outlets for headphones, audio PCM internal

Keywords: circular buffer Serial Communication Data Processing Algorithm serial communication Serial Data Processing 1. Background Analysis In many practical engineering applications, communication methods are usually RS232, RS485, I2C, and SPI. These interfaces share a common feature: communication by byte streams, that is, each interruption, indicates that a byte is successfully transmitted or received. Some interfaces transmit data blocks, that is,
