About this Reference
This manual documents the control and measurement functions provided by the remote interface to the R-2550
and R-2600 Communications System Analyzer Series (R-2600, R-2660, R-2670, R2680). It is intended to provide
all the information necessary to develop application programs that remotely control both units. General usage of
the R-2600 analyzers is described in the R-2600 Communications System Analyzer Series Operator’s Manual,
publication 68-80386B72. General usage of the R-2550 analyzers is described in the R-2550 Communications
System Analyzer Operators Manual, publication 68-80309E.54.
All of the analyzer models operate in a similar manner and many of the remote command are identical for all
products. Where there are differences in the remote commands for the analyzers, the text clearly identifies them.
Section 1
Introduction discusses configuration requirements, the layer model provided by the remote interface, and the three
modes of operation: Standard RS-232, Extended RS-232, and IEEE 488.2.
Section 2
Interface Functions discusses remote and local operations, RS-232 and IEEE 488.1 protocols, and print functions.
Section 3
Syntax Overview discusses the Talker and Listener syntax provided by the analyzer. Differences between the
syntax of the Standard RS-232 mode and the Extended RS-232 and IEEE 488.2 modes are explained.
Section 4
Status Reporting discusses the control and status data structures provided by the IEEE 488.2 model. The
capabilities of the model that are provided when operating under RS-232 control are described.
Section 5
Programming Conventions discusses optional command parameters and optional response parameters.
Section 6
Command Set Organization presents an overall description of the command set; describing command groupings
and manual entries for the commands. A quick reference to the command set is also provided.
Sections 7 and on
The individual command and query pages give detailed descriptions of each command, including syntax,
parameters, responses, and special notes.

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 interface. An IEEE 488 interface is not available on the R-2550 analyzer. Either of
these interfaces may be used to remotely control the analyzer using a set of commands, queries, and responses that
are defined within this document.
Note
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.
Note
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
Vol.05 or greater.
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.

Note
Application programs using the Standard RX32 model can gain access to the Extended RS-232
model via the G2 command.
Standard RS-232 Mode
When the analyzer is initially powered on, it assumes all communications will occur over the RS-232 hardware
interface using the Standard RS-232 mode. On the R-2600, if activity is detected on the IEEE 488 interface, the
R-2600 will immediately switch to the IEEE 488.2 mode. The Standard RS-232 mode is completely backward
compatible with versions of software before Version VO1.0.5. Application programs written for older versions of
software can utilize the Standard RS-232 mode without change.
Extended W-232 Mode
The Extended RS-232 mode provides some additional services from the IEEE 488.2 specification while operating
over the RS-232 hardware interface. Within this mode, all of the IEEE 488.2 status and data structures and
syntactic definitions are available to provide a consistent and powerful remote interface while still relying upon
the RS-232 hardware for the low-level communications interface.
IEEE 488.2 Mode
The IEEE 488.2 mode provides a remote interface via the IEEE 488.1 hardware that is fully compliant with the
IEEE 488.2 specification. This is the only mode of operation available for the IEEE 488 interface. The most
important aspect of this specification is the status and error control/reporting capabilities, defmed in Section 4.

2. Interface Functions
Remote, Local, and Local Lockout
The analyzer can be in one of three states: power off, local (front panel) control, and remote control. Upon
power-up, the analyzer will automatically enter the local control state.
The R-2550 enters the remote control state upon detection that a remote device is trying to take control over the
RS-232 interface. Once in the remote control state the R-2550 executes commands input through the RS-232
interface.
The analyzer enters the remote control state upon detection that a remote device is trying to take control over
either the RS-232 or IEEE-488 interfaces. Once in the remote conuol state the analyzer executes commands input
through the remote control interface.
The only front panel controls available to the operator are:
l power switch
l squelch knob
l brightness control knob
l volume control knob
.
“go to local” hard key
The Fl hard key functions as the “go to local” key while in the remote control state. A local lockout feature is
available when the analyzer is in the remote control state. The “go to local” hard key is not accepted while the
local lockout feature is enabled. The local lockout feature is disabled upon entering the remote control state.
The analyzer will remain in the remote conuol state until any of the following occtm
l a “go to local” keystroke from front panel
l detection of “go to local” from remote controller
l power is switched off
The analyzer display indicates the unit is under remote control as long as it is in the remote control state. While
the local lockout feature is enabled the display indicates local lockout is enabled. An indication that the Fl key is
the “go to local” key is displayed if and only if the local lockout feature is disabled and the analyzer is in the
remote control state.
The analyzer will enter the local control state upon:
l powerup
l detection of the “go to local” command (GL) through the remote control interface

IEEE 488 (available only on the R-2600)
The IEEE 488 interface provides a high-speed hardware interface supporting communication among multiple
devices within the same area. Each device on the IEEE 488 bus has its own address, allowing the Controller in
charge to communicate directly with any device on the bus. Devices can either talk or listen, depending on if the
device is transmitting information or receiving information, respectively.
The interface capabilities of the R-2600, as defined by IEEE 488.1, are SHl, AHl, TE6, LE4, SRl, RLl, PPO,
DCl, DTl, CO, and E2.
The R-2600 allows both primary and secondary addressing. Both Primary addresses and Secondary addresses
range from 0 to 30. Secondary addressing can be disabled. The R-2600 uses the same address for both Talk and
Listen modes.
The IEEE 488 address of the R-2600 is accessed from the Remote Interface menu. To modify the address, press
the SPF hardkey on the front panel. The Special Functions screen will be displayed. Cursor down to the Remote
Interface selection and press the Display Table softkey. The Remote Interface screen will be displayed. The screen
allows modification of both the Primary and Secondary addresses.
Note
The Primary and Secondary address selections will only be available on the Remote Znterface
menu if the R-2600 is equipped with the ZEEE 488 option.
To disable secondary addressing, place the cursor on the Secondary Address and press the Disable softkey. The
Secondary Address will be displayed as two dashes, indicating that Secondary Addressing has been disabled-

Note
The IEEE 488 Secondary Address will initially be disabled when the R-2600 is shipped from the
factory. The Reset capabilities of the R-2600 will not alter the Primary or Secondary Address
settings - they can only be modified under local control by operator interaction.

Print Functions
The standard print function gives the user the opportunity to send the data displayed on the R-2600 CRT display
to a printer. When the cPR1, key is selected on the front panel, the data is sent over the RS-232 serial bus in
ASCII format. With the standard print function, only the text information is printed, the scope trace data is not
printed.
If the R-2600 has the Graphics Mode Option installed, the screen data can be sent over the RS-232 serial bus as
graphics data. If the user’s printer is capable of IBM-EPSON graphics, all of the data displayed on the CRT will be
printed, including the scope Uace.
The Graphics Control Command Sequence to implement 8-pin Bit Image Mode Graphics is as follows:
ESC+@
Printer Initialization.
EsC+A+S Line Space Setting
ESC+L+nl+nZ Dot Density, number of columns of dots per line
Where: ESC =

3. Syntax Overview
The analyzer functions as a Listener when accepting information from a controiler and as a Talker when
responding with information back to the controller. The syntax for both the Listening and Talking formats is
defined using BNF notation, which is described below.

Listening Formats
The analyzer meets all required IEEE-488.2 encoding syntax. The syntax is specified to be very flexible to allow a
maximum variety of controller’s to utilize the analyzer remote interface. This flexibility also allows the analyzer
language to appear in a form that is more understandable to the reader.
The following list gives the syntax for a <Terminated Program Message>, which is the syntax accepted by the
analyzer as a Listener.
