INTRODUCTION
This reference and programming guide contains condensed specifica-
tions and information which describes the various features of the
Model 485. Each feature is described in three segments of informa-
tion. The first segment describes the features. The second segment
gives an exact procedure on how to use the feature. The third seg-
ment gives application examples. These segments are brief, but the
information presented in this format is designed for a quick reference
of the Model 485 features and functions. Refer to the Model 485 In-
struction Manual for complete information and essentialsafety infor-
mation.
With the Model 4853 IEEE-488 interface installed, the Model 485 can
be controlled over the IEEE-488 bus. This booklet also contains infor-
mation concerning Model 485 bus operation. Several example pro-
grams using some commonly used controllersare outlined to get the
Model 485/4853 “up and running”.
