FAQ: IBM Midrange System and 5250 Terminal Connection through Desktop Expansion Card

Do you have questions regarding the connection of an IBM midrange system and a 5250 terminal via a desktop expansion card? Here are some answers to frequently asked questions:

What is an IBM Midrange System?

The term IBM Midrange System refers to a series of computer systems developed by IBM for mid-sized businesses and enterprises. Examples of IBM Midrange systems are AS/400 and System/3x. These systems are known for their stability, reliability, and flexibility.

What is a 5250 Terminal?

A 5250 terminal is a type of display terminal used for accessing IBM Midrange Systems. It is named after the primary communication protocol used by these terminals. The 5250 protocol is a proprietary protocol developed by IBM for connecting terminals to its midrange systems.

What is a Desktop Expansion Card?

A desktop expansion card is a device that is inserted into a computer’s expansion slot to add new features or functions to the computer. In the case of connecting an IBM Midrange System and a 5250 terminal, a desktop expansion card is used to provide the necessary communication interface between the two systems.

How Does a Desktop Expansion Card Connect an IBM Midrange System to a 5250 Terminal?

A desktop expansion card used for connecting an IBM Midrange System and a 5250 terminal typically comes with a 5250 emulation program and a communication interface. The communication interface connects to the IBM Midrange System’s communication port, while the emulation program emulates a 5250 terminal on the computer’s screen.

When the expansion card and the emulation program are installed, the user can connect the computer to the IBM Midrange System using a standard serial cable. The emulation program then translates the user’s keystrokes and mouse clicks into 5250 protocol commands, which are sent to the IBM Midrange System.

What Are the Benefits of Connecting an IBM Midrange System to a 5250 Terminal via a Desktop Expansion Card?

Connecting an IBM Midrange System to a 5250 terminal via a desktop expansion card offers several benefits:

  • Cost-effective solution: A desktop expansion card is a more affordable alternative to purchasing a dedicated 5250 terminal.
  • Flexibility: Users can connect to the IBM Midrange System using any PC or laptop equipped with the expansion card and emulation software.
  • Reduced footprint: Using a desktop expansion card eliminates the need for a separate 5250 terminal and reduces the All things considered footprint of the workstation.

The result

Connecting an IBM Midrange System and a 5250 Terminal through a desktop expansion card offers a cost-effective, flexible, and practical solution for businesses and enterprises. By providing a communication interface and emulation program in one device, a desktop expansion card simplifies the process of connecting a computer to an IBM Midrange System and allows users to access the system using a standard PC or laptop.
