This article mainly to RS232 to explain the Java serial communication technology. RS232 Communication Basics Rs-232-c (also known as EIA Rs-232-c, hereinafter referred to as RS232) was in 1970 by the American Electronics Association (E IA) Joint Bell System, modem manufacturer, and computer terminal manu

Currently, the commonly used serial ports include 9-pin serial ports (DB9) and 25-pin serial ports (DB25). When the communication distance is close (1. Description of common signal ports of DB9 and DB259-pin serial port (DB9) 25-pin serial port (

interface plug-in cable we use complies with the serial port standards, it can be used flexibly in practice, various protocols are used in serial port interface standards for communication and Device Control.We have learned about the serial port protocol. In our daily work, we are most exposed to the external interfaces of some actual devices. How can we know from the shape that this interface is? How to define each pin of cables? Above we know the s

Protocol, so long as we use the interface plug-in cable to meet the standard of the actual use of flexible, in the serial port Interface standards using a variety of protocols for communication and equipment control. The above we understand the serial port protocol, and our daily work in contact with the most is the actual equipment of the external interface, how we know from the shape that it is that kind of interface. Make a definition of how the cables are each stitch. We know that. Serial

The Console port of a vro usually has an "Internet Explorer" mark or an abbreviation of "Internet Explorer. Insert the other end of the reverse cable into the RJ45 socket on the adapter (adapter. Then, insert the DB9F header of the adapter into the 9-pin serial port of the terminal. If the terminal serial port is equipped with a DB25M (25

Parallel Port In 1284, the IEEE 1994 standard defined five parallel transmission modes: 1) compatibility mode 2) nibble Mode 3) byte mode 4) EPP enhanced parallel port Mode 5) ECP Extended Parallel Port The hardware connector of the parallel port is db25, which is divided into three groups, such 1) Data lines (Data Bus) data lines2) control lines3) status linesThe data line is used to transmit data. The control line is used to control peripheral dev

computers is the serial port, which now has at least two serial port COM1 and COM2. The serial port differs from the parallel port in that its data and control information is transmitted serially by one after another. In this way, although the speed is slower, but the transmission distance is longer than the parallel port, so long-distance communication should use a serial port. Typically, COM1 uses a 9-pin D-shaped connector, while COM2 some use an

involve connectors, cables or protocols, on the basis of which users can establish their own high-level communication protocol. BecauseThis is an application in the video industry. Many manufacturers have established a set of high-level communication protocols, either open or exclusively used by manufacturers. For example, the recorder manufacturers Sony and Panasonic on the video recorder RS-422 control protocol is differentMore control protocols are available on the video server. For example,

one of the most widely used serial interfaces in PC and communication industry. A RS-232 is defined as a single-ended standard that increases communication distances in low-rate serial communication. The RS-232 adopts the unbalanced transmission mode, that is, the so-called single-ended communication. Figure 1 (see the figure below) The data signal sent and received is relative to the signal location. For example, the data sent from the DTE device is 2-
