5250 REMOTE EMULATOR CARD

3. Introduction

3.1 General Overview

Thank you for purchasing a 5250 Remote Emulator Card. We hope that the Card helps you meet all of your PC-to-twinax connectivity needs.

The 5250 Remote Emulator Card brings the best of the twinax and PC worlds together by connecting your IBM® AS/400® or System/3X to a PC either directly or across a phone-line-plus-sync-modem SDLC link. The Card, which operates in DOS or Windows (under a DOS partition), lets your PC emulate (act like) any of several controllers or display stations and lets your PC’s printer emulate several types of system printers. At the time of this writing, it is the fastest card of its type on the market, capable of local operation at up to 64 kbps or remote operation at up to 128 kbps. It emulates a 5394 remote controller, which gives it the capability of working with PC Support software on the AS/400. The Card has 132-column capability and supports multiple languages.

3.2 Interfaces Supported

The 5250 Remote Emulator Card supports these three interfaces:

•EIA RS-232D, known internationally as V.24, is a standard for interfacing Data Terminal Equipment (DTEs) with Data Communications Equipment (DCEs) over short distances.

•X.21 is a general purpose interface between DTEs and Data-Circuit- Terminating Equipment (DCTs) for operating on synchronous Public Data Networks (PDN) that provide dialup and leased-line services for data communication. X.21 supports transmitting at speeds up to

64 Kbps to a maximum distance of 1000 meters (3280.8 feet).

•V.35 is a high-speed interface. The 5250 Remote Emulator Card supports V.35 transmission at speeds up to 128 kbps (for remote applications) or up to 64 kbps (for local applications) to a maximum distance, depending on your data rate and the type of cable you use, of 600 to 1200 meters (1968.5 to 3937 feet).
