1. Introduction
The R-2550, and the R-2600 are both equipped with a standard RS-232 interface. Optionally, the R-2600 is
equipped with an
IEEE 488
these interfaces may be used to remotely control the analyzer using a set of commands, queries, and responses that
are defined within this document.
Throughout this document, the term analyzer is used to refer to either the R-2550 or the R-2600.
Whenever digerences exist between the finctionality of the two products, specific references to
the model are made.
Configuration Requirements
All R-2550 software versions are capable of providing the applicable capabilities described throughout this
reference.
The R-2600 must be equipped with software version VOI .05 or greater to use the capabilities described throughout
this reference. Software versions preceding VO1.05 provide the remote control capabilities described in the
original, and the "1 June 91? printing of the Motorola R-2600 Communications System Analyzer Operator's
Manual, publication 68-P80386B72. The original printing has no date on the back cover. Subsequent revisions
show the revised printing date on the back cover.
Application programs developed for older versions of the R-2600 sofrware are firlly compatible
with the material described in this document.
To use the IEEE-488 interface, the R-2600 must be equipped with the IEEE-488 option and software version
The set of installed options can be determined by accessing the Version menus. To determine the software version,
press the SPF hardkey on the front panel. The Special Functions screen will be displayed. Cursor down to the
Version selection and press the Display Table softkey. The Version screen will be displayed. Cursor down through
each of the major option selections and press the DispZay Table softkey. The installed options will be displayed.
Layer Model
The Communications Analyzer is designed to act as a device under the influence of a controller. Communication
between the Analyzer and a controller is accomplished using a set of codes and formats as defined in one of two
models. Each model is built upon a layered protocol, which allows controllers using the RS-232 interface to
access the IEEE 488.2 communications protocols.
The layer model defines four different levels of communication that occur between the analyzer and a controller.
At the lowest layer, the R-2600 supports either the RS-232 or the IEEE 488.1 hardware interfaces. Above this
layer, the R-2600 supports either the IEEE 488.2 syntax and data structure model or the backwards-compatible
RS-232 remote interface. An additional set of common IEEE 488.2 commands and queries exist at the third layer,
providing access to the IEEE 488.2 data structures. The fourth and highest layer provides analyzer specific
commands and queries.
