1 Introduction

In this publication, items relevant only to the RM3544-01 are indicated as RM3544, and items relevant only to the RM3545, RM3545-01, and RM3545-02 are indicated as RM3545. Also, the RM354-01, RM3545, RM3545-01, and RM3545-02 are indicated as “the instrument.”

If the commun ica tio n mo ni tor in g func ti on is us ed at th e ti me o f pro g ram c re at io n, com man ds an d r es po ns es will be conveniently displayed on the measurement screen. For information on the communication monitoring function, see the instruction manual of the instruments.

Various messages are supported for controlling the instrument through the interfaces. Messages can be either program messages, sent from the controller such as PC to the instrument, or response messages, sent from the instrument to the controller.

Message types are further categorized as follows.

Messages

Controller

Program Messages

Response Messages

Program Messages

Instrument

Command Messages

Query Messages

Response Message

When issuing commands that contain data, make sure that the data is provided in the specified format.

Message Format

 Program Messages

Program messages can be either Command Messages or Query Messages.

(1) Command Messages

Instructions to control the instrument, such as to change settings or reset

Example: (instruction to set the measurement range)

RESISTANCE:RANGE 100E3

Header portion

Space Data portion

Query Messages

(2)

Requests for responses relating to results of operation or measurement, or the state of instrument settin gs Example: (request for the current measurement range)

RESISTANCE:RANGE?

Header portion Question mark

See: “Headers (p.2)”, “Separators (p.3)”, “Data Formats (p.4)”



 Response Messages

When a query message is received, its syntax is checked and a response message is generated. The

:SYSTem:HEADer

Header ON Header OFF

command determines whether headers are prefixed to response messages.

:SENSE:RESISTANCE:RANGE 100.000E+03

100.000E+03

(The current resistance measurement range is 100kΩ)

At power-on, Header OFF is selected. If an error occurs when a query message is received, no response message is generated for that query. Some query message has no header, such as

:FETCH?

and

:CALCulate:LIMit:RESult?

 Command Syntax

Command names are chosen to mnemonically represent their function, and can be abbreviated. The full command name is called the “long for m”, and the abbreviated name is called the “short form”. The command references in this manual indicate the short form in upper-case letters, extended to the long form in lower case letters, although the commands are not case-sensitive in actual usage.

ADJUST? ADJ ADJU AD

Response messages generated by the instrument are in long form and in upper case letters.

Headers



Headers must always be prefixed to program messages.

(1) Command Program Headers

There are three types of commands: Simple, Compound and Standard.

• Headers for Simple Commands

This header type is a sequence of letters and digits

:ESE0

• Headers for Compound Commands

These headers consist of multiple simple command type headers separated by colons “:”

:SAMPle:RATE

• Headers for Standard Commands

This header type begins with an asterisk “*”, indicating that it is a standard command defined by IEEE 488.2.

RST

(2) Query Program Header

These commands are used to interrogate the instrument about the results of operations, measured values and the current states of instrument settings.

As shown by the following examples, a query is formed by appending a question mark header.

:FETCh? :CALCulate:LIMit:REFerence?

OK (long form) OK (short form) Error Error

“

”

after a program

Characters within square brackets [ ] may be omitted.

[:SENSe:]RESistance:RANGe :SENSe:RESistance:RANGe

RESistance:RANGe

Either form is valid



 Message Terminators

This instrument recognizes the following message terminators (delimiters):

[RS-232C/USB]

•

CR+LF

[GP-IB]

•

Depending on the instrument's interface settings, the following can be selected as the terminator for response messages. For information on settings, see “Delimiter Setting” (p. 61).

LF CR+LF EOI LF with EOI

[RS-232C/USB]

•

CR+LF

[GP-IB]

•

LF with EOI (default setting) CR+LF with EOI

 Separators

(1) Message Unit Separator

Multiple messages can be written in one line by separating them with semicolons “;”

:SYSTEM:LFREQUENCY 60;*IDN?

• When messages are combined in this way and if one command contains an error, all subsequent messages up to the next terminator will be ignored.

• A query error occurs if a query command is combined with an immediately followed semicolon and subsequent command.

(2) Header Separator

In a message consisting of both a header and data, the header is separated from the data by a space “ ” (ASCII code 20H).

:SYSTEM:HEADER OFF

Data Separator

(3)

In a message containing multiple data items, com mas ar e re quired to separate the data items fro m o ne an othe r.

:CALCulate:LIMit:BEEPer IN,1,0



 Data Formats

The instrument uses character data, decimal numeric data and character string data depending on the command.

Character Data

(1)

Character data always begins with an alphabetic chara cter, a nd subs eque nt chara cter s ma y be either alphabetic or numeric. Character data is not case-sensitive, although response messages from the instrument are only upper case. When the command data portion contains <1/0/ON/OFF>, the operation will be similar to when 0 is OFF and 1 is ON.

:SYSTEM:HEAD ER OFF

Decimal Numeric Data

(2)

Three formats are used for numeric data, identified as NR1, NR2 and NR3. Numeric values may be signed or unsigned. Unsigned numeric values are handled as positive values. Values exceeding the precision handled by the instrument are rounded to the nearest valid digit.

NR1 Integer data (e.g.: +12, -23, 34)

•

NR2 Fixed-point data (e.g.: +1.23, -23.45, 3.456)

•

NR3 Floating-point exponential representation data (e.g.: +1.0E-2, -2.3E+4)

•

The term “NRf format” includes all three of the above numeric decimal formats. The instrument accepts NRf format data. The format of response data is specified for each command, and the data is sent in that format.

Note: A “+” sign is returned as a space (ASCII code 20H).

:ESE0 106

:FETCH? +106.5710E+03

(3) Character string data

• Character string data is enclosed by quotation marks.

• This type of data consists of 8-bit ASCII characters.

• Characters that cannot be handled by the instrument are replaced by a space.

• As for quotation marks, the sender uses double quotes ( ") on ly, w hile the re ceiver r eceiv es both d ouble qu otes and single quotes (').

:SYSTem:PANel:NAME “PANEL_01”

[GP-IB]

The instrument does not fully support IEEE 488.2. As much as possible, please use the data formats shown in the Reference section. Also, be careful to avoid constructing single commands line that could overflow the input buffer or output queue.

(A “+” sign is returned as a space (ASCII code 20H).



 Compound Command Header Omission

When several commands having a common header are combined to form a compound command (e.g.,

:CALCulate:LIMit:REFerence

together in sequence, the common portion (here, occurrence. This common portion is c alle d the “current path” (analog ous to the path concept i n c omp ute r fil e s torag e), and until it is cleared, the interpretation of subsequent commands presumes that they share the same com mon portion.

and

:CALCulate:LIMit:PERCent

:CALCulate:LIMit:

) can be omitted after its initial

) if they are written

This usage of the current path is shown in the following example:

Full expression

:CALCulate:LIMit:REFerence 1.0E+3;:CALCulate:LIMit:PERCent 1.0

Compacted expression

:CALCulate:LIMit:REFerence 1.0E+3;PERCent 1.0

This portion becomes the current path, and can be omitted from the messages immediately following.

The current path is cleared when the power is turned on, when reset by key input, by a colon “:” at the start of a command, and when a message terminator is detected. Standard command messa ges can b e ex ecuted r egar dless o f the current path. T hey hav e no effe ct upon t he curren t path.

A colon “:” is not required at the start of the header of a Simple or Compound command. However, to avoid confusion with abbreviated forms and operating mistakes, we recommend always placing a colon at the start of a header.

Output Queue and Input Buffer

Output Queue



Response messages are stored in the output queue until read by the controller. The output queue is also cleared in the following circumstances:

• Power on

• Device clear [GP-IB]

• Query Error

The output queue capacity of the instrument is 64 bytes. If response messages overflow the buffer, a query error is generated and the output queue is cleared. Also, with GP-IB, if a new message is received while data remains in the output queue, the output queue is cleared and a query error is generated.

Input Buffer



The input buffer capacity of the instrument is 256 bytes. If 256 bytes are allowed to accumulate in this buffer so that it becomes full, the USB and GP-IB interface bus enters the waiting state until space is cleared in the buffer. The RS-232C

Note: Ensure that the no command ever exceeds 256 bytes.

interface will not accept data beyond 256 bytes.



Status Byte Register

[GP-IB]

This instrument implements the status model defined by IEEE 488.2 with regard to the serial poll function using the service request line. The term “event” refers to any occurrence that generates a service request.

Overview of Service Request Occurrence

The Status Byte Register contains information about the event regi sters and the output q ueue. Requi red items ar e selected from this information by masking with the Service Request Enable Register. When any bit s elected b y the mask is set, bit 6 (MSS; the Master Summary Status) of the Status Byte Register is also se t, which generates an SRQ (Service Request) message and dispatches a service request.

Note: SRQ (Service Request) is a GP-IB function only. However, STB (Status Byte

[RS-232C/USB]

RS-232C/USB does not provide a function for issuing service requests. Still, SRER setup and STB reading are available.

Service Request Enable Register (SRER)



 Status Byte Register (STB)

During serial polling, the contents of the 8-bit Status Byte Register are sent from the instrument to the controller. When any Status Byte Register bit enabled by the Service Request Enable Register has switched from 0 to 1, the MSS bit becomes 1. Consequently, the SRQ bit is set to 1, and a service request is dispatched.

The SRQ bit is always synchronous with service requests, and is read and simultaneously cleared during serial polling. Although the MSS bit is only read by an

Device-Specific Event Status Registers (ESR0 and ESR1)



This instrument provides two Event Status Registers for controlling events. Each event register is an 8-bit register. With RM3545 Event Status Register 1, only RM3545 is valid.

When any bit in one of these Event Status Registers enabled by its corresponding Event Status Enable Register is set to 1, the following happens:

• For Event Status Register 0, bit 0 (ESB0) of the Status Byte Register (STB) is set to 1.

• For Event Status Register 1, bit 1 (ESB1) of the Status Byte Register (STB) is set to 1.

Event Status Registers 0 and 1 are cleared in the following situations:

Command Execution Time

Command execution time indicates the time for analyzing and processing long form commands. However, the command execution time for commands with data is the time described according to the data format specified in the <data portion>, and for query commands it is the time when the header is ON.

• Display delays may occur depending on the frequency of communication processes and process contents.

• All commands except

• In communications with the controller, time must be added for data transmission. USB and GP-IB transfer time depends on the controller. The RS-232C transfer time, with start bit 1, data length 8, no parity, and stop bit 1, has a total of 10-bit. When the transfer speed (baud rate) setting is N bps, the general result will be as follows:

Transfer time T [1 character/sec] = Baud rate N [bps]/10 [bits] Since a measurement value is 11 characters, a 1 data transfer time will be 11/T. (Example) For 9600 bps, 11/(9600/10) = Approx. 11 ms

Wait until measurements stabilize after a change before using a setting command.

*1 If there is a counter-electromotive force, such as a transformer, the switching takes longer due to the hot

switching prevention function for the relay. The hot switching prevention function is canceled when the counter-electromotive force is lost or a maximum 1 second + delay set value elapses.
