Preface
This reference manual describes the capabilities, operating
procedures, programming considerations, features and special
features of the IBM 545 Output Punch. It also contains the
information required by an operatorortrainee to use the
545 efficiently. The reader is assumed to haveat least an
introductory knowledge of data processing.
The manual has two major sections: Keypunch Mode and
Autopunch Mode. "Keypunch Mode" presents a complete
description of the 545 as a manual card punch. The reader
whois not familiar with IBM keypunch, machines(e.g. the
24/26, 29, or 534/536) should read this section first. Those
who have had experience with keypunch type machines may
prefer to proceed to "Autopunch Mode," which presents a
complete description of the 545 as an output punch for
system use.
The user may or may not choose to use the power.and
signal resources of the 545 Output Punch. However, the
functions and procedures described in this manual are based
on the assumptionthat all power andsignals necessary to
output punchoperation originate in the 545.
