Terminals - Adapters: 157727-1 Application Field and Working Principle

157727-1 is an international standard for data terminal and adapter systems. This standard specifies the electromagnetic compatibility of data terminals and adapters that serve as a link between a computer and its associated peripherals, such as terminal printers, communication equipment, keyboards, and external memory. Data terminals and adapters are used in most data processing and communication systems, providing interfaces between the operator and the computer using a variety of interfaces and protocols.

157727-1 Overview

The 157727-1 standard is a set of technical requirements for data terminals and adapters. It defines the functional and environmental requirements for all data terminals and adapters, including the electrical and mechanical components, the data and control interfaces, the power supply, and the cables and connectors. The standard also establishes rules for the interoperability of terminals and adapters, including the requirements for compatibility and the applicable testing procedures. The purpose of this standard is to promote the interoperability of data terminals and adapters and to set forth the principles involved in achieving reliable and efficient operation of data terminals and adapters.

Application Field of 157727-1

The 157727-1 standard is applicable to data terminals and adapters with active or passive components operating in either binary or parallel logic. The standard applies to terminals and adapters that link a host computer to one of the following devices: * Local area networks (LANs)* Serial and parallel printers* Terminals and modems* Displays* Communication systems* Keyboards* Point-of-sale (POS) systems* External memory systemsThe standard is applicable to new terminals and adapters, as well as to existing terminals and adapters that have been upgraded or modified in order to meet the requirements of the standard.

Working Principle of 157727-1

The 157727-1 standard requires that all terminals and adapters must meet specific performance criteria and must not interfere with the normal operation of other devices. The criteria are based on a variety of parameters, including: * Electrical characteristics: This specifies the allowed voltage and current limits for the terminal and adapter. * Timing: This specifies the minimum and maximum response times for the terminal and adapter. * Signaling: This specifies the number of bits per data unit and the code for control signals. * Coupling: This specifies the type of cables and connectors used to connect the terminal and adapter. * Data formats: This specifies the format of the data to be handled by the terminal and adapter. In addition, the 157727-1 standard also provides rules for the interoperability of terminals and adapters within a network. These rules ensure that each terminal and adapter can communicate with all other terminals and adapters in the network without interference. The standard also specifies the testing procedures to be used to ensure that the terminals and adapters comply with the performance and interoperability requirements. Finally, the 157727-1 standard also includes guidelines for the installation and maintenance of terminals and adapters. The guidelines specify the procedures to be followed when installing, operating, and maintaining terminals and adapters. The guidelines also outline the procedures that should be followed in the event of a fault or system failure.

Conclusion

The 157727-1 standard is an important tool for ensuring interoperability and reliability in data terminal and adapter systems. The standard provides a set of guidelines and requirements for both the electrical and mechanical components of the terminals and adapters, as well as for the signal formats and data formats used. The standard also provides guidelines for the installation and maintenance of terminals and adapters. By following the standards and procedures outlined in the 157727-1 standard, designers and users of data terminals and adapters can ensure a more reliable and efficient system.
