Normaly between DTE and DSE elements connected using RS-232/RS-422 signal levels as local computer, terminals, etc.., that are communicating with each other using a broad range of standard [[communication protocol]]s in [[Point-to-point (telecommunications)|point-to-point telecommunications]]. To collect and analyse signals and data of interfaces making use of RS232 or RS422 physical layers with a baud rate from 300 to 38,400. Once captured on the internal memory can be analysed using the viewing CRT or LCD screen or saved on some magnetic support for a later analysis.<ref name="Wright2004">{{cite book|author=Edwin Wright|title=Practical Industrial Data Networks: Design, Installation and Troubleshooting|url=https://books.google.es/books?id=qyQ9LMmL2tMC&pg=PA46&dq=serial+protocol+analyzer&hl=ca&sa=X&ei=2HLRVKSHBszsaNmVgcgO&ved=0CDkQ6AEwAQ#v=onepage&q=serial%20protocol%20analyzer&f=false|year=2004|publisher=Newnes|isbn=978-0-7506-5807-2|pages=46–}}</ref> ==Caracteristics == Serial protocol analyzers, with the appropiate interfaces, they support a wide range of physical layer standards such as RS-232C, RS-422/485, Current loop, I2C, IrDA, CAN/LIN. Nowadays, even USB protocol analysers are available as well. They can be used in any kind communication network maintenance and in the testing and development of communication systems. They allow monitoring data transferred between the different kinds of equipment that use the supported types of serial communications; PCs, PC peripheral devices, printers, modems or other communication sets as sequencers, robots, NC machines, etc... Serial protocol analyzers Mainly,they are of great help to support the development and later maintenance of the the systems/programs of controllers and sequencers used in factories. that come with measurement captured data for its analisis in a PC program. <!-- Ya lo he puesto, recuerda que el director de Mkting the Isecom (un tal Lozano) me mandó a gastos pagados a Rockville Ma. (como service eng.) había olvidado el apellido de David Carvey cené en su casa cerca de la central de la CIA.. pasamos por delante.. lo bueno era como subías al Washington Shuttle.. como si subieras al autobús , te cobraban el billete a bordo con la bacaladera..y el avión al aterrizar pasaba tocando un puente con el tren..vamos! años más tarde uno lo tocó y...support a wide range of protocols such as RS-232C, RS-422/485, Current loop, I2C, IrDA, CAN/LIN. In addition, we develop USB protocol analyzers as well. LINE series enable you to monitor data between the equipment that use serial communication; PCs, peripheral devices for PC, communication equipment, printers, sequencers, NC machines and robots etc. LINE series can be used for anything with the development and the testing of communication systems and communication network maintenance. Moreover, these are helpful to support the development and the maintenance of the systems that come with measurement data captured on PC, the systems/programs of the sequencers and the controllers in factories. LM-5100RS is a board order to use an extended set of multi-protocol analyzer as the LM-5000H80 instrument laptop. ______________________ This board can be used in standard memory capacity of 80MB buffer bytes, corresponding to the high-speed data communications 99.9Kbps. Because it is equipped with a full keyboard, you can easily send data such as data entry and key support at the time of simulation in the LM-5000H80. Also, when the monitor can be seen in the (backlit) LCD large screen of 640 × 400 dot, analysis, etc. can be done efficiently. Large memory buffer 400K bytes buffer memory as available. Can also be used as a buffer memory for the built-in hard disk of 80M bytes of LM-5000H80 In addition, it is also possible to measure continuously for long periods of time. Can be measured with a resolution of 1ms, 10ms, 100ms time (no communication) Idol of the communication data. For this reason, and the response time of data transmission and reception of short time, the timing of the data and signal interfaces, such as the status of long time-out occurs at a glance.--> ==Control Characters used == * ENQ (0x05) Enquiry to start communications * ACK (0x06) Acknowledge (data received and no errors * NAK (0x15) Negative Acknowledge (data received but there were errors) * SOH (0x01) Start of Header * ETB (0x17) End of Transmission Block (intermediate block) * STX (0x02) Start of Text (beginning of data block) * ETX (0x03) End of Text (end of last data block) * EOT (0x04) End of Transmission (transaction complete) ==Self standing analyzers== Line monitoring function allows the communication data records, and provides an easy to understand large-sized display, without affecting the communication line. This feature makes it possible to grasp the sending and receiving of conditions, thus greatly reducing the time required for troubleshooting. As a standard feature, the line monitors support multiple communication standards, such as binary synchronous communications (BSC), for the character synchronous transmission, and high-level data link control (HDLC), for bit-synchronous transmission, and asynchronous communication are widely for PC peripherals and microcontroller applications. <!-- The line monitor function allows the recording of communications data and provides an easy-to-understand large-sized display without affecting the communications lines.

LE-150PS supports ASYNC communications. With PC, it can be used as high performance protocol analyzer and have Monitor function and Simulation is transparent to the connected devices. You might run into trouble when using modems, however: Because DCD (Carrier Detect) cannot be easily passed through to the other serial port, the host can't detect a modem connection. You can solve this problem by wiring DSR (Data Set Ready) high, and ignoring the DCD signa The data is shown in hex and ASCII, eight bytes per line. Each log entry has a time stamp, which shows the reception time of the first character. t can convert attributes such as baud rates or parity, and can also do data protocol conversions by embedding ==Protocols == ==Synchronous == ==Asynchronous== ===ASCII control code chart=== {| class="infobox" |- ! <ref>MS-DOS QBasic v1.1 Documentation.
