Executive Summary

Customers migrating from the A6748A/A6749A PCI Multiplexer (MUX) adapter solution to the AD278A/AD279A PCI MUX solution may encounter device communication failure. This is because of the RS-232 pin-layout and port interface incompatibility between these two solutions. This white paper discusses these instances of incompatibility, and describes how to customize the peripheral device cables to achieve successful migration. This white paper addresses the following topics:

• Hardware information about A6748A/A6749A and AD278A/AD279A serial PCI MUX solutions

• RS-232 pin-layout of A6748A/A6749A and AD278A/AD279A serial PCI MUX solution

• Instances of incompatibility

• Instructions for customizing peripheral device cables to resolve instances of incompatibility

Intended Audience

This white paper is intended for HP support personnel, HP customers, and converter cable manufacturers.

Introduction

Customers who are migrating from the A6748A/A6749A PCI MUX adapter solution to the AD278A/AD279A PCI MUX solution may encounter device communication failure. This is because of the RS-232 pin-layout and port interface incompatibility between these two solutions. This white paper identifies the different scenarios in which customers can face issues of incompatibility. It also describes solutions to achieve successful migration.
