PRINTING HISTORY
New editions are complete revisions of the manual. Update packages, which are issued between editions, contain
additional and replacement pages to be merged into the manual by the customer. The date on the title page and back

PREFACE
This manual contains installation and serv1c1ng information for
the HP 300208 Intelligent Network Processor (INP). The INP is
a functionally flexible, single-channel data processor that pro-
vides I/O capability between the HP 3000 HP-IB Version Computer
Systems and other computer systems via either modulator/de-
modulators (modems) and telephone lines or direct connection. In
this manual, the HP 3000 HP-IB Version Computer Systems refers to
the HP 3000 Series 30,33,40,44 and 64 Computer Systems.
This manual was written with the assumption that the reader has a
thorough knowledge of the HP 3000 HP-IB Version I/O system and
is familiar with the latest data communications techniques.
This manual is organized as follows:
Section I, General Information, briefly describes the main
features of the INP and how it operates. This section also
describes how the INP is configured in the computer system,
lists the equipment supplied with the INP, and lists its
specifications.
Section II, Installation, contains instructions for installing
the !NP printed circuit assembly (PCA) and its interconnecting
cabling into an HP 3000 HP-IB Version Computer System.
Section III, Principles of Operation, is a description of the
hardware operation of the INP and its associated communication
channels. Since this is a brief overview, intended only to
give the user a better understanding of how the INP does its
job, some minor operational details have been omitted.
Section IV, Maintenance, contains general serv1c1ng inform-
ation, troubleshooting procedures, repair instructions, and a
description of applicable maintenance aids.
