.1 GP-IB Interface

.1.1 Outline

The GP-IB (General Purpose Interface Bus) was developed as an interface for general use by programmable instrumentation, and as an interface is rich in expandability and has many distinctive features.

There are various interfaces with specific names apart from the GP-IB, such as the IEEE-488 bus, the IEC bus, and the HP-IB which is an internal standard within the Hewlett-Packard Company. These are basically the same standard, but, because the number of connector pins and the arrangement of the signals and so on differ, much care should be exercised.

GP-IB and RS-232

Interface

In this explanation of management and operation, only the GP-IB related resources of the 8835 and 8826 will be described.

If more detailed knowledge of the GP-IB interface is required, reference should be made to the following literature: The Institute of Electrical and Electronics Engineers, Inc.: "IEEE Standard Digital Interface for Programmable Instrumentation", IEEE Std 488.1-1987, IEEE Std 488.2-1987 (1987)

2.3 Setup Procedure

────────────────────────────────────────────────────

.4 Receive and Send Protocols

(1) Messages

Data received or sent by the GP-IB or RS-232C interface is called a message. The following are the message types:

Message

Program messages Response message

Of these, program messages are those received by the unit from the controller, while response messages are those sent from the unit to the controller. Program messages are command messages or query messages. Command messages are orders for control of the device, such as for making settings or for reset or the like. Query messages are orders for responses relating to the results of operation, results of measurement, or the state of device settings. Response messages are sent in response to query program messages. After a query message has been received, a response message is produced the moment that its syntax has been checked.

Command program message Query program messages

(2) Command syntax

When no ambiguity would arise, the term "command" is henceforth used to refer to both command and query program messages.

The unit accepts commands without distinction between lower case and upper case letters.

The names of commands are as far as possible mnemonic. Furthermore, all commands have a long form, and an abbreviated short form. In command references in this manual, the short form is written in upper case

letters, and then this is continued in lower case letters so as to constitute the long form. Either of these forms will be accepted during operation, but intermediate

forms will not be accepted. Further, during operation both lower case letters and upper case letters will be accepted without distinction. The unit generates response messages in the long form (when headers are enabled) and in upper case letters.

(Example)

For "DISPlay", either "DISPLAY" (the long form) or "DISP" (the short form) will be accepted. However, any one of "DISPLA", "DISPL", or "DIS" is wrong and will generate an error.

────────────────────────────────────────────────────

2.4 Receive and Send Protocols

Data

────────────────────────────────────────────────────

(3) Command program headers

Commands must have a header, which identifies the command in question. There are three kinds of header: the simple command type, the compound command type, and standard command type.

Simple command type header

The first word constitute the header.

Exampl

Simple comman type header

:HEADer ON

Compound command type header

A header made up from a plurality of simple command type headers marked off by colons.

Exampl

:CONFigure:TDIV 1.E-3

Simple command type header

Compound command type heade

Dat

Standard command type header

A command beginning with an asterisk and stipulated by IEEE 488.2

Exampl

*RST

(4) Query program headers

These are for commands used for interrogating the unit about the result of an operation or about a setting. These can be recognized as queries by a question mark appearing after the program header. The structure of the header is identical to that of a command program header, with "?" always being affixed to the last command. There are queries possible in each of the three previously described types of command form.

Exampl

:HEADER? ON

Query program header

Dat

(5) Response messages

Response messages relating to queries are made up from header portions (which also may be absent due to header disablement) and data portions identical to those of program messages, and as a general rule are sent in an identical format to the format of the program message corresponding to their originating query.

────────────────────────────────────────────────────

2.4 Receive and Send Protocols

────────────────────────────────────────────────────

(6) Terminators and separators

Message Terminator

A terminator is used in order to separate the transmission of one message from another, and this terminator is not itself included in the message.

GP-IB interface

LF, EOI, or LF+EOI is used as the message terminator, and LF+EOI is also used as the response message terminator.

RS-232C interface

Set the delimiter for the message terminator (see Section 2.3.2).

Message Unit Separator

A semicolon ";" is used as a message unit separator when it is desired to set out several messages on a single line.

Exampl

:CONFIGURE:TDIV 1. E-3;:CONFIGURE:SHOT 1

Message unit separato

Header separator

With a message which has both a header and data, a space "_" is used as a header separator to separate the header from the data. The space "_" is used by way of explanation, but it does not appear on the actual program.

Exampl

:CONFIGURE:SHOT_1

Header separato

Data separator

Commas are used as data separators for separating several data items from one another.

Exampl

Simple command type heade Compound command type heade

:DISPLAY:DRAW CH1,DARK

Data separato

Header separato

(7) The command tree

The rule when writing several messages of compound command form on the same line, when no colon is prefixed to the next header after the semicolon (the message unit separator), is that that header is considered as continuing on from the header before the last colon in the message directly preceding. This corresponds to the general concept of the current directory in the directory structure of UNIX or MS-DOS, and this directly preceding header is called the "current path".

Example

:CONF:TDIV 1. E-3;:CONF:SHOT 1 :CONF:TDIV 1. E-3;SHOT 1

Both Example 1 and Example 2 are messages setting TIME/DIV to 1 ms and recording length to 15 divisions. With Example 1, because there is a colon directly after the semicolon, the current position is the "root". Accordingly the reference of the next command is performed from the root.

────────────────────────────────────────────────────

2.4 Receive and Send Protocols

────────────────────────────────────────────────────

On the other hand, with Example 2, because with ":CONF:TDIV 1. E-3;" the current path has become ":CONF", it is now possible to omit the ":CONF:" before "SHOT".

To reiterate, the colon at the beginning of a command forces the search for the command to begin from the root. Thus in Example 1:

:CONFIGURE:TDIV 1.E-3

The first colon indicates that the "CONFIGURE" command is at the root level.

(8) Data format

The unit uses character data, decimal data and character string data as a data format.

Character data

The first character must be alphabetic. The characters after the first character can only be alphabetic characters,

numerals, or underline characters (_).

As alphabetic characters, during sending only upper case letters are used,

but during receiving both upper case and lower case letters are permitted.

Decimal data

Decimal data values are represented in what is termed NR format. There are three types of NR format from NR1 to NR3, and each of these can appear as either a signed number or an unsigned number. Unsigned numbers are taken as positive.

Further, if the accuracy of a numerical value exceeds the range with which the unit can deal, it is rounded off. (5 and above is rounded up; 4 and below is rounded down.)

NR1 format - integer data

Examples: +15, -20, 25

NR2 format - fixed point numbers

Examples: +1.23, -4.56, 7.89

NRf forma

NR3 format - floating point number

Examples: +1.0E-3, -2.3E+3

The term "NRf format" includes all these three formats.

When the unit is receiving it accepts NRf format, but when it is sending it utilizes whichever one of the formats NR1 to NR3 is indicated in the particular command.

Character string data

Character string data is enclosed within quotation marks.

The data is composed of 8 bit ASCII characters. Characters which cannot be handled by the unit are replaced by spaces.

When the unit is sending, only the double quotation mark (") is used as a quotation mark, but when receiving both this double quotation mark and also the single quotation mark (’) are accepted.

────────────────────────────────────────────────────

.5 The Status Byte and the Event Registers

(1) The status byte

Each bit of the status byte is a summary (logical OR) of the event register

corresponding to that bit.

Further, for GP-IB, the status byte and each event register has an enable

(which starts off at zero when the power is turned on) it is possible to mask

the service requests originating from each event.

For RS-232C, only the values for the status byte, standard event status

.6 The Input Buffer and the Output Queue

(1) Input buffer

The unit has an input buffer of 1024 bytes capacity.

Messages which are received are put into this buffer and executed in order.

However, an ABORT command is executed instantly as soon as it is received.

(2) Output queue

The unit has an output queue of 512 bytes capacity.

Response messages are accumulated in this queue and are read out from the

controller.

If the length of a response message has exceeded 512 bytes, a query error

occurs.

The circumstances when the output queue is cleared are as listed below:

1. When the controller has read out its entire contents.

2. When a device clear is issued.

3. When the power is turned off and turned on again.

4. Upon receipt of the next message.

.7.1 GP-IB

(1) Remote Control

Local state

This is the state in which the unit is controlled by its keys. When the power is turned on, the unit always comes up in local state.

Remote state

In this state the unit is controlled from the GP-IB interface (the REN line is "true"), and its keys are disabled. When in the remote state, the unit returns to local state if the local key (the [LOCAL] function key) is pressed.

Local lockout state

When an LLO (Local Lockout) command (this is a GP-IB universal command) is received, even if the local key is pressed, the unit is prevented from returning to the local state. This state is called the local lockout state.

In order to return the unit from the local lockout state to the local state, it is necessary either (a) to send a GTL (Go To Local) command (this is a GP-IB universal command), or (b) to turn the power to the unit temporarily off and then on again, or (c) to bring the line REN to "false".

If a command is sent with REN in the "false" state, then the only way to return to the local state is with the local key.

(2) Device Clear

When the unit receives the device clear command, it clears the input buffer and the output queue (see Section 2.6).

The device clear command is exemplified by the following: HP 9816 (made by Hewlett-Packard) CLEAR 7

────────────────────────────────────────────────────

2.7 Others

────────────────────────────────────────────────────

(3) GP-IB Errors

When a command which has been received contains an error, that one of bits 2

to 5 of the standard event status register which corresponds to the event

which has occurred is set.

Further, if a command has given rise to an error (apart from an execution

error), commands accumulated in the input buffer and waiting for execution

after that command are ignored.

.7.2 RS-232C

RS-232C Errors

(1) Parity error

The parity bit can be set to even parity, odd parity, or no parity. When even or

odd is selected, the "1" count is used to detect transmission errors. If the

parity count is different at the receiving end, a parity error is returned.

(2) Framing error

When counting from the start bit, if the stop bit is "L", a framing error is

returned.

Possible reason (1): Transmission rate, parity, stop bit or other parameter

setting mismatch

Possible reason (2): Noise

(3) Overrun error

The transmission controller uses double buffering for receiving data (shift

buffer for each bit and reception buffer read by the CPU).

When there are data in the reception buffer, and the shift register completes

reception of the next character before the data are read by the CPU, an

overrun error occurs. Because the new data overwrites the previous data in

the reception buffer, immediately preceding data are lost.

Possible reason (1): Transmission rate is too high.

Possible reason (2): Some interrupt inhibit intervals are too long.

Possible reason (3): Execution time for higher-priority interrupt is too long,

reducing the time available for the receive interrupt.

────────────────────────────────────────────────────

2.7 Others

────────────────────────────────────────────────────

Flow Control

The RS-232C interface can transfer data at the selected transfer rate, but if the CPU cannot keep up with the data that are being sent, later data will overwrite data that were received earlier. To prevent this, the receiving side must alert the sending side when the reception buffer is about to become full, so that the transfer can be temporarily paused. This is called flow control. Two types of flow control are possible, namely hardware handshaking and software handshaking.

(1) Hardware handshaking

Flow control is performed by setting the signal lines RTS (RS) and CTS (CS) to ON and OFF.

Receiving data

When input buffer content exceeds 3/4, RTS is set to Low. When input buffer content falls below 1/4, RTS is set to High.

Sending data

When CTS becomes Low, data send is interrupted. When CTS becomes High, data send is resumed.

(2) Software handshaking

Flow control is performed using the Xon and Xoff code.

Receiving data

When input buffer content exceeds 3/4, D3 (13H) is sent. When input buffer content falls below 1/4, D1 (11H) is sent.

Sending data

When D3 (13H) is received, data send is interrupted. When D1 (11H) is received, data send is resumed.

Note: Buffer size is as follows.

Input buffer: 1024 bytes Output buffer: 512 bytes

.2 Detailed Explanation of the Commands

NOTE

■ The products consultable this manual: 8826, 8835, 8835-01, 8841, 8842

.2.1 Explanation

The following sections describe the format and functions of individual commands. The following is an example of how the descriptions are organized.

Example

■ Changes and queries the function selection. Common

Syntax command :FUNCtion A$ query :FUNCtion? response A$ = MEM : memory recorder function REC : recorder function RMS : RMS recorder function

Explanation Switches to the function designated by A$. Returns the name of the current function as character data

Example :FUNCtion:MEM The function is set to the memory recorder function.

When allowed In MEM, REC and RMS

Command function Command syntax

command gives the syntax of a command program message, query the syntax of a query program message, and response the format of the response message. The parameters, referred to as data, are shown as follows:

A, B, C,... Numerical data (e.g. 1.5, 10E-3) A$, B$,... Character data (e.g. A, B1, GND, OFF)

"A", "A$",... Character string data (e.g. "1.5", "mA") (Single quotation marks (’) can be used instead of double quotation marks

(").)

The format of numerical data follows the formats <NR1>, <NR2>, and <NR3>.

Example

A <NR1> Numerical parameter in NR1 format B <NR2> Numerical parameter in NR2 format C <NR3> Numerical parameter in NR3 format

────────────────────────────────────────────────────

3.2 Detailed Explanation of the Commands

────────────────────────────────────────────────────

NOTE

If no format is mentioned, <NR1> format is accepted.

NR1 format integer data NR2 format fixed point numbers NR3 format floating point numbers The term "NRf format" includes all these three formats.

When the unit is receiving a command or query program message, it accepts format, but when it is sending it utilizes whichever one of the formats <NR1> to <NR3> is indicated in the particular command. Response messages may or may not have headers prefixed.

Explanation of the command function. Example of command use. This lists the functions in which the command may be used.

MEM memory recorder function REC recorder function RMS RMS recorder function

Models Common Common command that can be used for all the models 8835 Command that can be used for the 8835 8835-01 Command that can be used for the 8835-01 8826 Command that can be used for the 8826 8841 Command that can be used for the 8841 8842 Command that can be used for the 8842 8720 Command that can be used for the 8720

Execution of commands

・Commands are input into the input buffer and are executed in order. ・However the :ABORT command is executed immediately, even if commands

are waiting in the input buffer - more precisely, at the instant its terminator is received.

・Commands other than those which can be handled by the unit in its current

state are not executed but generate execution errors. This happens, for example, when in memory recorder function it is attempted to execute a recorder mode setting.

・Further, almost all commands cannot be executed during measurement

operation.

8841 and 8842

Commands related to FFT, and recorder and memory functions are supported from Version 2.00.

Regarding the command for specifying the channel number

Unless specifically mentioned, the ch$ character string specifying the channels becomes as follows. ch$ = CH1 to CH4 (8835)

CH1 to CH8 (8835-01) CH1 to CH16 (8841, 8842, 8720) CH1 to CH32 (8826)

────────────────────────────────────────────────────

3.2 Detailed Explanation of the Commands

OPT? Commo

■ Queries device option provision.

Syntax query *OPT? response ch1 <NR1>, ch2 <NR1>,..., ch4 <NR1> (8835) ch1 <NR1>, ch2 <NR1>,..., ch8 <NR1> (8835-01)

ch1 <NR1>, ch2 <NR1>,..., ch32 <NR1> (8826) ch1 <NR1>, ch2 <NR1>,..., ch16 <NR1> (8841, 8842, 8720)

ch1: Whether or not channel 1 input unit present ch2: Whether or not channel 2 input unit present

. . . ch32: Whether or not channel 32 input unit present

0: not present 1: analog unit 2: voltage/temperature unit 3: strain unit 4: FFT unit 5: F/V unit 6: charge unit 7: 4-channel unit

Explanation Whether or not input unit present is returned as an NR1 numerical value.

────────────────────────────────────────────────────

3.2 Detailed Explanation of the Commands

────────────────────────────────────────────────────

2. Internal operation commands

RST Commo

■ Device initial setting.

Syntax command

*RST

Explanation Initializes the unit (same as system reset). Note It does not clear GP-IB and RS-232C related items.

(the event registers, the enable registers, the input buffer and the output queue)

TST? Commo

■ Queries the result of the ROM/RAM check.

Syntax query *TST? response A <NR1> A =0,1 0: normal 1: failure

Explanation The result of the ROM/RAM check of the unit is returned as an NR1

numerical value.

Note If the unit communicates with LAN, it can not receive the response.

3. Synchronous commands

OPC Commo

■ After all action has been completed during execution, sets the LSB (bit 0) of SESR (the standard event status register).

Syntax command *OPC Explanation When the command preceding the *OPC command completes execution, the

LSB of SESR is set.

Example :FUNC MEM; *OPC;:CONF:TDIV +500.0E-6

A$ B$

(After the execution of the commands A$ and B$ is completed, the LSB of SESR is set.)

────────────────────────────────────────────────────

3.2 Detailed Explanation of the Commands

────────────────────────────────────────────────────

OPC? Commo

■ After execution is completed, replies with ASCII [1].

Syntax query

*OPC?

response 1 Explanation When the command preceding the *OPC command completes execution, the

response of ASCII [1] is made.

WAI Commo

■ After the execution of the command is completed, subsequently performs the following command.

Syntax command *WAI Example A$;B$;*WAI;C$

The command C$ following *WAI is not executed until the execution of the commands A$ and

B$ is completed.

4. Status and event control commands

CLS Commo

■ Clears the status byte and associated queues (except for the output queue).

Syntax command *CLS Explanation This instruction clears the event register associated with each bit of the status

byte register. It also clears the status byte register.

Note Because it does not clear the output queue, it has no effect upon bit 4 (MAV)

of the status byte.

────────────────────────────────────────────────────
