Our goal is to make installation of your C-size VXI system as easy as possible. To o so, HP VIC (HP VXI Installation Consultant) is provided with the HP E1406A Command Module. HP VIC is a Microsoft® Windows program that helps you configure and install the HP E1406A Command Module - based on VXI systems. If your syste m contains an HP E1406A Command Module to be controlled by a com puter ex ternal to the VXI mainframe, it is recommended you configure your syste m using HP VIC.

Chapter 1 HP E1406A Command Module Overview 15

Command Module Functional Description

The HP E1406A Command Module is the foundation of a VXIbus system (see Figure 1-1). Though its role in a VXIbus system is largely transparent (for example, the user need not program its functions) it provides the following key functions:

• Translates SCPI (Standard Commands for Programmable

Instruments) commands for HP register-based inst ruments .

• Provides the VXIbus slot 0 and resource manager capabilities.

• Can drive the VXIbus TTLTRG0-7 and ECLTRG0-1 trigger lines.

The module contains SMB connectors for placing an external trigger onto the selected line(s), and for routing an internal trigger to a device external to the mainframe.

• Contains an internal clock that allows you to set and read the time

and date.

• Is the Hewlett-Packard Interface Bus (HP-IB) to VXIbus interface.

Command Module Physical Description

The HP E1406A Command Modu le occup ies one C-size mainframe slot . The faceplate has annunciators, clock and trigger connectors, interface ports, and extraction levers that are described below.

Faceplate

Annunciators

There are four annunciators on the HP E1406A faceplate which show the following:

Failed Shows that the command module has failed its power-on

self-test or has stopped working at some point in time.

SYSFAIL Shows that the SYSFAIL line on the VXIbus backplane is

being asserted by the command module when it fails.

Access Shows that the command module is accessing, or being

accessed by the VXIbus backplane.

Ready Shows that the command module is in the VXIbus normal

operation state.

Figure 1-2. HP E1406A Command Module Faceplate

Chapter 1 HP E1406A Command Module Overview 17

Faceplate CLK10

and Trigger

Connectors

There are four signal connectors on the HP E1406A faceplate which function as follows:

Clk In This SMB connector allows an external 1 0 MH z clo ck to functio n

as the system’s slot 0 CLK10 resource. T his is a high impedance input with an input range from ± 40 mV to ± 42.5 V.

Clk Out This SMB connector allows the internal slot 0 CLK10 resource

to be routed to other VXIbus mainframes. This output is a TTL level output and drives 50 Ω.

Trig In This SMB connector allows an external trigger signal (TTL

levels) to be applied to the system on the trigger line selected (TTLTRG0-7/ECLTRG0-1). The input impedance is 5 kΩ.

Trig Out This SMB connector allows an internal trigger on the trigger line

specified (TTLTRG0-7/ECLTRG0-1) to be applied to an external device. This output is a TTL level output and drives 50 Ω.

The HP-IB and

RS-232 Ports

The Run/Load

Switch

The HP-IB port allows an HP-IB cable to be connected from the HP E1406A to a computer, or to an external disk drive. The RS-232 port can be used as a user interface, or used for peripheral control if the HP E1406A contains Instrumen t BASIC (IBASIC). The RS-232 port is a 9-pin DTE connector. Supported terminals includ e: HP 700/92, HP 700/94, HP 700/22, HP 700/43, Wyse WY-30, DEC VT 100, and DEC VT 220.

The run/load switch is located beneath the HP-IB port. This switch lets you activate the loader instrument so that you c an reprogram the Flash ROM or download device drivers to the Flash ROM.

The Reset Button The reset button is located beneath the run/load switch. This button is used

to reconfigure your VXIbus system and return it to the power-on state.

Extraction Levers The extraction levers provide easy insertion into and extraction from the

C-size mainframe.

18 HP E1406A Command Module Overview Chapter 1

Installing the Command Module in a Mainframe

Refer to Figure 1-3 to install the HP E1406A Command Module in a C-size mainframe.

Set the extraction levers out.

Slide the HP E1406A into any slot until the backplane connectors touch.

Tighten the top and bottom screws to secure the command module to the mainframe.

NOTE: The extraction levers will not seat the backplane connectors on older VXIbus mainframes. You must manually seat the connectors by pushing in the module until the module’s front panel is flush with the front of the mainframe. The extraction levers may be used to guide or remove the command module.

Seat the command module into the mainframe by pushing in the extraction levers.

To remove the command module from the mainframe, reverse the procedure.

System Configuration Sequence

As mentioned in the C-Size VXIbus Syst ems Configur atio n Guide, the resource manager within the HP E1406A Command Module p erforms the following system config uration sequ en ce when power is applied:

• Identify all statically and dynami cally configured pl ug-in m odul es

installed in the C-size main fram e.

• Set commander/servant hierarchies whereby one or more plug-in

modules control other plug-in m odules.

• Perform A24/A32 address mapping so modules requiring additional

addressing can receive it.

• Allocate interrupt lines to manage communication between interrupt

handler modules and int errupte r modules.

• Start system operation.

Once the power-on sequence is completed and the system is started, the resource manager is no longer used.

Chapter 2 Configuring the HP E1406A Command Module 21

The following sections describe each step of the configuration sequence. Included are examples on how to change the sequence using configu ration tables stored in non-volatile user RAM.

Note Refer to the C-Size VXIbus Systems Confi gura tion Guide fo r in form ation on

configuring the HP E1406A Command Module as the resource manager.

Modules Configured Statically and Dynamically

Statically configured modules are plug-in modu les whose log ical addresses are set with logical address switches. Dynamically configured modul es are plug-in modules who se logical addresses are programmed (s et) by the resource manager.

Identifying

Statically

Configured Modules

Identifying

Dynamically

Configured Modules

Once all power-on self tests have completed, the resource manager identifies all statically configured modules. The resource manager retains information such as the modul e’s logical ad dr ess, slot nu mber, model number, manu facturer’s code, and so forth.

Once all statically configured modules have been located in a mainframe and none have a logical address of 255, the resource manager identifies all dynamically configu red modules an d assign s them logical ad dr esses as follows.

• The resource manager locates dynamically configured modules by

scanning each mainframe slot. Refer to the plug-in module manual for additional information on sett ing up the modu le prior to its dynamic configuration.

• Beginning with the lowest mainframe slot (excluding slot 0), the

resource manager scans each slot via the module identification (MODID) bus until a dynamically configured module is located. The module is assigned a logical address that is the low est available multiple of 8.

• The resource manag er con tinu es s cannin g unt il the nex t dyn amicall y

configured mod ul e is located . The mo dule i s assign ed a l ogical address that is the next avai lable mu ltip le of 8. The process continu es until all dynamically config ured devices have been ass ig ned logical addresses. If all mult iples of 8 are used, the d yn ami cally co nfi gured module is ass igned the firs t avail abl e add ress .

• Logical addresses used by statically configured devices will not be

assigned to dynamically configu red devices.

• Dynamically configured devices will not be assigned logical address 255.

• A set of address blocked dynamically configured devices will be

assigned successive logical addresses beginning with the lowest available multiple of 8.

22 Configuring the HP E1406A Command Module Chapter 2

User-Defined

Dynamic

Configuration

If your system contains instrum en ts comp rised of mult iple mo dules th at must have successive logical addresses, then the modules mus t be statically configured using thei r logical addr ess switches, or be dynamicall y configured with the user-defined dynamic configur ation table. The dynamic configuration table covered in this section allows you to override the default configuration process by assignin g logi cal addresses as you choose.

The Dynami c

Configuration Table

User-defined dynamic configurations are specified with a dynamic configuration table created in the command module. The table is created as follows:

1. Table space in the command module’s non-volatile user RAM is made available by allocating a segment of RAM with the command:

DIAGnostic:NRAM:CREate <size>

2. Reset the command module. NRAM is created during th e bo ot-up process:

DIAGnostic: BOOT:WARM

3. The location (starting address) of the table in RAM is determined with the command:

DIAGnostic:NRAM:ADDRess?

4. Data is downloaded into the table with the command:

DIAGnostic:DOW Nload <address >,<data>

5. The table is linked to the appropriate algorithm in the command module processor with the command:

VXI:CONFigure:DCTable <address>

Table Fo rm at The format of the dynamic configu ration tabl e is shown in Table 2-1.

Entries

The table parameters are:

• Valid Flag (1/0) 1 (one) indicates the table is valid and the modules

can be configured accordingly. 0 (zero) will cause an error message (Error 39). Valid Flag is part of the table header and is one byte.

• Number of Entries (1 - 254) is the number of entries in the table.

Number of Entries is part of the table header and is one byte.

Chapter 2 Configuring the HP E1406A Command Module 23

• Slot Number (1 - 12) is the mainframe slot the module to be

assigned an address is installed in. Field is one byte.

• Slot 0 Laddr is the logical address of the slot 0 device. This is 0

(zero) in mainframe #1 but will be different in any additional mainframes. Field is one byte.

• Laddr (1 - 254 ) is the logical address to which the module in Slo t

Number is set. Field is one byte.

• Block Size (1 - 128) is the number of d ev i ces in an add ress block.

When there is more than one device, Laddr specifies the logical address of the first device in the set. The remaining devices are assigned sequential logical addresses beginning with the next highest address. When there are multiple dev ic es in a slot that are not address blocked, there must be an entry in the table for each device. Field is one byte.

Determinin g the

Table Size

The dynamic configuration table has a two byte header and each of the four fields are one byte. The amount of RAM to allo cate with

DIAGnostic:NRAM :CREat e is computed as:

2 + 4(N)

where N is the number of modules to be configured. For example, to dynamically configur e three modules based on logical addr esses you have selected, the table size would be: 2 + 4(3) = 14 bytes.

DIAGnostic:NRAM :CREat e would be executed as:

OUTPUT @E1406;"DIAG:NRAM:CRE 14"

Data Format Data can be sent to the dynamic configuration table in any convenient

format, as long as the binary data is preserved. This can be accomplished

DIAGnostic: PEE K? and DIAGnostic:POKE, by r eading the data into a

using variable in the computer and then downloading the data to the table using the Arbitrary Block Program Data format, and so forth. In the following example, this is accomplished by r eading th e data into 16-bit integer variables in the computer and then downloading the data to the table using the ANSI/IEEE 488.2-1987 Arbit rary Block Program Data format. More information on the Arbitrary Block Prog ram format can be found on page 121 of this manual and in the ANSI/IEEE 488.2-19 87 document.

CAUTION When downloading data into the dynamic configuration table,

DIAGnostic:DOWNload does not determine if the table is large

enough to store the data. If the amount of data sent by

DIAGnostic:DOWNload is greater than the (tabl e) space allocated

by DIAGnostic:NRAM:CREate, system errors will occur. You can recover from these errors by executing DIAGnostic:BOOT:COLD, or by pressing the "Ctrl-R" keys on an RS-232 terminal while cycling mainframe power.

• Systems with multipl e VMEbus devi ces should be configur ed so that

the VMEbus devices in mainframes whose remote extenders have the highest logic al addresses shoul d also have the highest logi cal addresses.

• VMEbus devices should be configured to have the lowest addresses

on their particular VMEbus.

The resource manager will not attempt to perform any A16 address window configuration as a default. It will attempt to configure A24 and A32 memory according to the following rules:

• A memory page is

size of an A24 or A32 memory window is 2 pages and the maximum size of the window is 256 pages as defined in VXI-6 Specifications. For A24 memory a single page is 65,536 by tes an d the minimu m window size is 131,07 2 bytes. For A32 memory a single page is 16,777, 216 by tes an d the minimu m wind ow is 33,554,432 by tes.

• The base address of a memory window must be zero or an even

multiple of the size of the windo w.

• The window for a local extender will be set to the minimum poss ible

size to include all of the memory addresses found on all of its descendants.

• The window for a remote extender will be set to the minimum

possible size to include al l of the memory on its VMEbus and all of its desc endants.

• A VXIbus device will be assigned a memory location in the

following mann er:

– VXIbus devic es on a given VMEbus will be assigned memo ry

locations after all descendant busses of the VMEbus have been configured.

– VXIbus devic es on a given VMEbus will be assigned memo ry

locations in the range defined by the lowest and hig hest mem ory pages available for that bus.

– The first available page for a VMEbus will be the first page that

is higher than any reserved page on any of its ancestors.

– VXIbus devices will be assigned the lowest memory location s

available on the current bus.

– VXIbus devices will be assigned locations according to memory

size and logical address in that order. The device with the largest memory size on a given bus will be assigned an address first. For devices with the same size, the device with the lowest logical address will be assigned a memory locati on first.

– If possible, no devices will be assigned to memory locations in the

bottom or top addresses 000000

⁄8 of the total memory (for example, in A24 memory

- 20000016 or E0000016 - FFFFFF16).

• VMEbus reserved memory must be placed in locations that will not

interfere with windows previously configured. The only way the resource manager can know the location(s) of VMEbus memory is for you to provide this information in the user-defined memory table (see “A24/A32 Address Mapping” on page 44 for more details).

Interrupt Register

Configuration

TTL Trigger

Configuration

The rules listed below will be used to assign the configuration of the INTX Interrupt Register during system start-up unless yo u override them with entries in the user-defined extender table.

• The interrupt enable bits in the INTX Interrupt Register on every

extender will be enabled for each VMEbus interrupt line that has a VXIbus handler assigned.

• The interrupt enable bits in the INTX Interrupt Register on every

extender will be disabled for each VMEbus interrupt line that has no VXIbus handler assigned.

• For every VMEbus interrupt line that has a VXIbus interrupt handler

assigned, the direction will be set on each extender such that an interrupt on that line will be routed towards the VMEbus backplane that contains the handler.

Utility Register

Configuration

The default Utility Register configuration is shown in Table 2-2. Since the resource manager may have to reboot during the system configuration process (for example, to download a driver) the Utility Registe r is not a part of the extender table. This will help ensure that the SYSR ESET sig nal will propagate throughout the system during a reboot so that all of the cards will receive a hard reset.

If you wish to alter the contents of the Utility Regis ter you can use

DIAGnostic: POKE commands directly to the registers. Keep in mind that

this may alter the default system reboot process.

Extender Table

In many systems that use extenders, the standard boot-u p algorithms wil l not be suitable for your configuration. In such systems it will be necessary to unambiguously define your logi cal address and memory map ping for the boot-up configuration routi ne.

You can define your own logical address and memory m apping in a system with extenders by using the user-defined extend er table. This table is created as follows:

1. Table space in the command module’s non-volatile user RAM is made available by allocating a segment of RAM with the command:

DIAGnostic:NRAM:CREate <size>

2. Reset the command module. NRAM is created during th e bo ot-up process:

DIAGnostic: BOOT:WARM

3. The location (starting address) of the table in RAM is determined with the command:

DIAGnostic:NRAM:ADDRess?

4. Data is downloaded into the table with the command:

DIAGnostic:DOW Nload <address >, <data>

5. The table is linked to the appropriate algorithm in the command module processor with the command:

Determinin g the

Table Size

The user-defined extender table has a one word header and each of the 12 fields is also one word. The amount of RAM allocated with

DIAGnostic:NRAM :CREat e is specified in bytes. Since one word is

two bytes, the amount of RAM to allocate is computed as:

2 + 24(N)

where N is the number of modules to be configured. For example, to provide information for three extender devices, the table size would be:

2 + 24(3) = 74 bytes

DIAGnostic:NRAM:CREate

OUTPUT @E1406;"DIAG:NRAM:CRE 74"

would be executed as:

Data Format Data can be sent to the extender table in any convenient format, as long as the

binary data is preserved. This can be a ccomplished using and DIAGnostic:POKE, by reading the data into a variable in the computer and then downloading the data to the table using the Arbitrary Block Program Data format, and so forth. In the following exam ple, this is accomplished by reading the data into 16 bit integer variables in the computer and then downloading the data to the table using the ANSI/IEEE 488.2-1987 Arbitrary Block Program Data format. More information on the Arbitrary Block Program format c an be found on page 121 of this manual and in the ANSI/IEEE 488.2-1987 document.

The table header is sent as a single 16-bit word which must contain the Valid Flag and the numbe r of modules involved. For a valid table, the header is 256 plus the number of modules. For example, to indicate a valid table with seven entries, the header is 263 (256 + 7 = 263).

DIAGnostic:PEEK?

CAUTION When downloading data into the user-defined extender table,

DIAGnostic:DOWNload does not determine if the table is large

enough to store the data. If the amount of data sent by

DIAGnostic:DOWNload is greater than the table space allocated

by DIAGnostic:NRAM:CREate, system errors will occur. You can recover from these errors by executing DIAG:BOOT:COLD, or by pressing the "Ctrl-R" keys on an RS-232 terminal while cycling mainframe power.

Setting Commander/Servant Hierarchies

In a VXIbus system, a commander is a plug-in module which cont rols other plug-in modules. “Control” can be a commander such as the HP E1406A Command Mod ule tran slatin g SCPI comm ands, and/or serving as the HP-IB interface for (servant) modules within its servan t area.

During the configuration sequence, the resource manager assigns servant modules to a commander modu le based on the servan ts’ logi cal addresses and the commander’s servant area. The concept of the servant area is shown in Figure 2-1. The C-Size VXIbus Systems Configuration Guide shows how to set the command modul e’s servant a rea.

Figure 2-1. Example of Commander/Servant Hierarchy

Note the following regarding commander/servant relationships:

• A commander’s servant area is its logical address + 1, through

its logical address + its servant area switch setting.

• If within a given commander’s servant area (Figure 2-1) there is

another lower-level commander(s) (logical address 1), the given commander will control the lower-level commander. However, all modules within th e servant area of the lower-level command er (logical addresses 2 - 41) will be controlled by the lower-level commander.

• If there is a commander outside the servan t area of the command

module/resource manager, that command er becomes a top level commander. The resource manager will assign all mo dules wit hin the commander’s servant area to that commander, or to that commander’s lower-level commanders.

• The command module will always be the commander for IBASIC

even if IBASIC’s logical address (240) is outside the mo dule’s servant area. There can be multiple IBASICs in the same system since each is a servant to its respective command module. Note that there are no VXIbus registers for IBASIC.

In some systems you may need to assign a servant to a commander that is outside the commander’s servant area. In other systems, it may be necessary to change a module’s secondary HP-IB address, or assign secondary addresses to modules whose logical addresses ar e not instrument identifiers. These tasks can be accomplished with the user-defined commander/servant hierarchy table described in this section.

require that the cards in the set have sequential logical addresses. When instrument drivers su pport no n-sequenti al logical addresses, instruments that consist of non-sequential card sets must be created using th e user-defined commander/servant hierarchy table. There must be an entry in the table for every card in the instrument card set.

The User-Defined

required (memory size) and the logical address. Modules with the largest amount of memory are allocated addresses first. Modules with the same amount of memory are allocated addresses beginning with the lowest logical address.

• The top 2 MB of A24 addresses (used internally by the command

module RAM) can be allocated. However, the command module cannot access those addresses on th e other device.

• An address allocation table can be used to reserve blocks of

A24/A32 addresses for VMEbus devices. This table is also used to assign addresses other than the default addresses assigned by the resource manager.

44 Configuring the HP E1406A Command Module Chapter 2

• A24 address space is 16 MB and A32 address space is 4 GB. The

command module does no t have A32 address lines and cannot access A32 address space. However, it will allocate A32 address space for devices which can access it. A32 memory allocation is similar to A24 memory allocation.

Allocating Address

Space for VMEbu s

Devices

• A32 address space is 00000000

through FFFFFFFF16.

The resource manager (command module) has no way to determine when VMEbus devices have been installed in the system. As a result, the resource manager allocates addresses to VXIbus A24/A32 devices rather than to VMEbus devic es.

There are two ways to prevent addresses intend ed for a VMEbus device from being assigned to VXIbus devices. The first method is described below. The second method uses an address allocation table to "reserve" a block of addresses. The table u sed fo r this is described in the s ection “Reserving A24/A32 Address Space” beginning on page 48.

Allocating Address Space for VMEbus Devices: Method 1

1. Configure and install all modules (except VMEbus devic es) in the HP 75000 Series C Mainframe. This process is described in the C-Size VXIbus Systems Configurat ion Guide.

2. Turn on the mainframe and note section 6 of the resource manager’s configuration sequence (Figure 2-3).

Given the starting (offset) A24 addresses assigned to the devices and the size of each device’s memory (converted to hexadecimal), the A24 addresses not allocated can be det erm ined. For example, in Figure 2-3, the highest offset is 240000

with a size of 20000

(131,072 bytes converted to hexadecim al). Thus , for this system, A24 addresses from 260000

to DFFFFF16 are available to VMEbus

devices.

Note In systems that include VXI-MXI extenders you shoul d use a table to tell

the resource manager where your A24/A32 VMEbus memory is located. The resource manager cannot find VMEbus memory without this table.

Address Space

As previously mention ed , the resource manager cannot determine when VME devices have been installed in the system. To prevent the resource manager from allocating A24/A32 addresses intended for VME devices to VXIbus devices, the address allocation table is used. The A24/A32 address allocation table is also used to assign different addresses to VXIbus devices other than those (default) addresses assigned by the resource manager during power-on.

The A24/A32 Address

Allocation Table

The A24/A32 address allocation table is created and stored in the command module as follows:

1. Table space in the command module’s non-volatile user RAM is made available by allocating a segment of RAM with the command:

DIAGnostic:NRAM:CREate <size>

2. Reset the command module. NRAM is created during th e bo ot-up process:

DIAGnostic: BOOT:WARM

3. The location (starting address) of the table in RAM is determined with the command:

DIAGnostic:NRAM:ADDRess?

4. Data is downloaded into the table with the command:

DIAGnostic:DOW Nload <address >, <data>

5. The table is linked to the appropriate algorithm in the command module processor with the command:

VXI:CONFigure:MT ABle <address >

The table parameters are:

• Valid Flag (0/1) 1 (one) indicates the table is valid and the

addresses reserved accordingly. 0 (zero) will cause an error message (Error 43). Valid Flag is part of the table header and is represented by the upper eight bits of the header word.

• Number of Records is the number of address records in the table.

You must have one record for each VMEbus or VXIbus device for which memory is reserved. Number of Records is part of the table header and is represented by the lower eight bits of the header word.

• Laddr is the logi cal address of the VXIbus dev ic e for which

A24/A32 addresses are reserved. -1 specifies a VMEbus device. Field is one word.

• Addr space (24|32) is the address space being reserved.

24 specifies A24 addresses are being reserved. 32 specifies A32 addresses are being reserved. Field is one word.

• Frame ID (0-255) is the logical address of the slot 0 device for the

mainframe containing the VMEbus m emory blo ck (8-bit byte). This field must be included.

• Base addr (0 to 2

of the A24 or A32 addresses to be reserved. Field is two words (4 bytes) and is specified in decimal.

• Memory size (1 to 2

which addresses must be reserved. This field must be specified but is ignored if a VXIbus A24/A32 device is specified (Laddr). Field is two words (4 bytes) and is specified in decimal.

Table Size

The A24/A32 address allocation table has a one word header, the first two entries in the address record are one word each, and the second two entries are two words each. The amount of RAM allocated with

DIAGnostic:NRAM :CREat e is specified in bytes. Since one word is two

bytes, the amount of RAM to allocate is computed as:

2 + 12(N)

where 2 is the two byte header, 12 is the number of bytes per address record (2+2+4+4), and A24 addresses for two VMEbus devices, the table size would be: 2 + 12(2) = 26 bytes.

Data Format Data can be sent to the A24/A32 address allocation table in any convenient

format, as long as the binary data is preserved. This can be accomplished

DIAGnostic: PEE K? and DIAGnostic:POKE, by r eading the data into a

using variable in the computer and then downloading the data to the table using the Arbitrary Block Program Data format, and so forth. In the next example, this is accomplished by r eading th e data into 16-bit integer variables in the computer and then downloading the data to the table using the ANSI/IEEE 488.2-1987 Arbit rary Block Program Data format. More information on the Arbitrary Block Prog ram format can be found on page 121 of this manual and in the ANSI/IEEE 488.2-19 87 document.

The Table Header The table header is sent as a single 16-bit word which must contain the

Valid Flag and the number of address records. For a valid table, the header is 256 plus the number of records. For example, to indicate a

valid table with two records, the header is 258 (256 + 2).

CAUTION When downloading data into the A24/A32 address allocation

table, DIAGnostic:DOWNload does not determine if the table is large enough to store the data. If the amount of data sent by

DIAGnostic:DOWNload is greater than the (tabl e) space allocated

by DIAGnostic:NRAM:CREate, system errors will occur. You can recover from these errors by executing DIAGnostic:BOOT:COLD or by pressing the "Ctrl-R" keys on an RS-232 terminal while cycling mainframe power.

Interrupt Line Allocation

In a VXIbus system, communication and coordination betw een a commander module and its servant module(s) is often achieved using the VXIbus backplane inte rrupt lines. During the configuration sequen ce, the resource manager assigns interrupt lines to programmable interrupt handler modules and inte rrupte r modules .

Both commanders and servants can be interrupt handlers and/or interrupters. The command module which is a programmable interrupt handler, is not an interrupter. Thus, in systems where the command module is a servant to another commander, it communicates with th e commander throug h its Response and Data Low Registers (see the VXIbus System Specification).

This error occurs when an invalid logical address is specified in the A24/A32 address allocation table.

DIAGnostic:BOO T:CO LD

The assignment and use of the interrupt lines is described in Figure 2-5 and with the information which follows.

Figure 2-5. Example of Interrupt Lin e Allocati on

Chapter 2 Configuring the HP E1406A Command Module 53

Note the following regarding interrupt line allocation:

• There are seven VXIbus backplane interrupt lines. As the resource

manager, the HP E1406A Command Module assigns itself interrupt line 1 (default). Additional interrupt lines (up to all seven) can be assigned to the command module using the interrupt line allocation table. Interrupt lines no t as sign ed to p rog ram mab le h and ler s r ema in un a ssig ned .

• Many Hewlett-Packard modules have interrupt line 1 as their factory

setting. Thus, they are available for immediate use with the HP E1406A Comman d Module.

• Commander modules which are programmable int errupt handlers are

assigned interrupt lines 2, 3, 4,...7 ; beginning wit h the comm an der with the lowest logical address. Only one interrupt line is assigned per interrupt handler.

• Servant modules which are programmable interrupt handlers are also

assigned interrupt lines, beginning with the se rvant with the lowe st logical address. Only one interrupt line is a ssigned per inte rrupt handler.

• Servant modules which are programmable interrupters are assigned

the same interrupt line assigned to their command er.

• For modules which are not programmable, the interrupt line is

selected using jumpers on the modules. The interrupt line allocatio n table is used to tell the command module which line was selected.

The Interrupt Line

Allocation Table

The interrupt line allocation table allows you to assign addi tion al interrupt lines to a specific handler, reserve interrupt lines for non-programmable interrupt handlers and interrupters, and assign lines to VMEbus devices.

User-defined interrupt line allocations are specified with an interrupt line table created in the command module. The table is created as follows:

1. Table space in the command module’s non-volatile user RAM is made available by allocating a segment of RAM with the command:

DIAGnostic:NRAM:CREate <size>

2. Reset the com m and mo du le. NRAM is created during the boot-up process:

DIAGnostic:BOOT:WARM

3. The location (starting address) of the table in RAM is determined with the command:

DIAGnostic:NRAM:ADDRess?

4. Data is downloaded into the table with the command:

DIAGnostic:DOW Nload <address >, <data>

5. The table is linked to the appropriate algorithm in the command module processor with the command:

Intr Line

• Intr Line (1 - 7) is the interrupt line to be assigned to the

programmable interrupt handler or interrupter, or the line reserved for a non-programmable interrupter/handler or VMEbus devic e. Field is one word.

• Handler La dd r is the logical ad dr ess of the p rog rammable handler

which will handle interrupts on the line specified by Intr Line. If -1 is specified, the line is reserved and no handler is assigned. The field is one word.

• Number of Interrupters is the number of programmable

interrupters on the interrupt line specified by Intr Line. If 0 is specified, there are no programmable interrupters. This reserves the line for a non-programmable interrupter. The field is one word.

• Intr Laddr is the logical address o f the prog rammable interrupter

on the interrupt line specified. The logical address of each programmable interrupter on the line must be specified. Programmable interrupters can be assigned to interrupt lines with no handler. This allows a programmable interrupter to have a non-programmable interrupt handler handle its interrupts. If Number of Interrupters is 0, Intr Laddr is not specified.

Chapter 2 Configuring the HP E1406A Command Module 55

Determinin g the

Table Size

The interrupt line allocation table has a one word header and each data record contains three words, plus one word for each programmable interrupter logical address specified. The amount of RAM allocated with

DIAGnostic:NRAM :CREat e is specified in bytes. Since one word is two

bytes, the amount of RAM to allocate is computed as:

2 + 6(N) + 2

∑

where 2 is the two byte h e ader, 6 is the numbe r of bytes/data record, N is the number of data records (for example, interrupt lines) and

M is the

number of programmable interrupters per data record. For example, to create a table for the following:

– one interrupt handler – two interrupt lines – one interrupter on one line, three interrupters on second line

the table size would be:

2 + 6(2) + 2(4) = 22 bytes | | (2 records) (4 interrupters)

DIAGnostic:NRAM :CREat e

OUTPUT @E1406;"DIAG:NRAM:CRE 22"

would be executed as:

Note When assigning an addit ional in t errupt line to an interrupt handler, yo u

must specify each line. Otherwise, the table will overwrite the line currently assigned, giving the handler only on e line. For example, if the resource manager assigns interrupt line 2 to a handler and you want to also assign line 3 to the handler, lines 2 and 3 must be specified in the table. See “Example: Assigning an Interrupt Line” on page 57.

Data Format Data can be sent to the interrupt line allocation table in any convenient

format, as long as the binary data is preserved. This can be accomplished

DIAGnostic: PEE K? and DIAGnostic:POKE, by r eading the data into a

using variable in the computer and then downloading the data to the table using the Arbitrary Block Program Data format, and so forth. In the following example, this is accompli shed by re ading th e data into 16 bit integer variables in the computer and then downloading the data to the table using the ANSI/IEEE 488.2-1987 Arbit rary Block Program Data format. More information on the Arbitrary Block Prog ram format can be found on page 121 of this manual and in the ANSI/IEEE 488.2-19 87 document.

56 Configuring the HP E1406A Command Module Chapter 2

The table header is sent as a single 16-bit word which must contain the Valid Flag and the number of data records. For a valid table, the h eader is 256 plus the number of data records. For example, to indicate a valid table with one data record, the header is 257 (256 + 1 = 257).

CAUTION When downloading data into the interrupt line allocati on table,

DIAGnostic:DOWNload does not determine if the table is large

enough to store the data. If the amount of data sent by

DIAGnostic:DOWNload is greater than the (tabl e) space allocated

The following example shows how an addit ional in t errupt line is assigned to a programmable interrupt handler and reserved for a non-programmable interrupter (Figure 2-6).

Figure 2-6. Assigning an Additional Interrup t Line

The program assumes that a VXIbus system contains an HP E1411B 51⁄2-Digit Multimeter that is a servant to a se cond HP E1406A Command Module at logical address 64. Since the command module is the only other commander and is a programmable interrupt handler, it is assigned interrupt line 2 by the resource manager. The HP E1411B, however, ha s its interrupt jumper set for line 3. For the multimeter to com municate w ith the c omma nd module, the command module must also be assigned to handle interrupt line 3.

Comments • Although interrupt line 2 was assigned to the comman d mod ule at

logical address 64 by the resource manager, the line must be "re-assigned" when line 3 is assigned. Otherwise, line 3 will be assigned in place of line 2.

• The interrupt lines assigned by the interrupt line table are used by the

system until

DIAGnostic: BOO T:CO L D is ex ec u t ed.

• When using multipl e command m odul es, HP -IB cables must be

connected from the slot 0 command module, to each command module in the system.

58 Configuring the HP E1406A Command Module Chapter 2

• In this program, the command modul e at logic al address 64 has a

primary HP-IB address of 08. It has a servant pointer setting of 32, thus its servant area is from logical addr ess 65 to logical ad d ress 96. If the HP E1411B multimet er has a logical address of 80, its secondary HP-IB address is 10. Thus, when programming thi s multimeter, its HP-IB address is:

OUTPUT 70810;"....

When programming this command m odul e, its HP-IB address is:

OUTPUT 70800;"...

• The following errors are associated with the Interrupt Line

Allocation table:

ERROR 24: INTERRUPT L INE UNAVAIL ABL E

This error occurs when an interrupt line assigned by the user-defined interrupt line allocation table is not available. Either the line has already been assigned or has been reserved. This error also occurs if the line being assigned to an interrupter is not handled by the interrupter’s commander.

ERROR 25: INVALID UDEF HANDLER

This error occurs when the logical address specified in the user-defined interrupt line allocation table for the interrupt handler (Handler Laddr) is a device that is not a valid interrupt handler.

ERROR 26: INVALID UDEF INTE RRUPTE R

This error occurs when the logical address specified in the user-defined interrupt line allocation table for the interrupter (Intr # Laddr) is a device that is not a valid interrupter.

ERROR 41: INVALID UDEF INTR TABLE

This error occurs when the user-defined interrupt line allocation table is not true (valid flag does not equal 1).

ERROR 42: INVALID UDEF INTR TABL E DATA

This error occurs when the user-defined interrupt line allocation table has invalid data; the number of records and/or the int errupt line specified is less than 1 or greater than 7, or there is an invalid interrupt handler and/or interrupter logi cal address (valid addresses are 0 to 255).

• The interrupts assigned by the interrupt line allocation ta ble are used by

the system until is executed.

Chapter 2 Configuring the HP E1406A Command Module 59

Starting System Operation

The resource manager completes the configuration sequence by issuing the "Begin Normal Operation" (BNO) comma nd to all top level comm and ers and to each of its direct message based servants. BNO is not sent to register based modules. The module receiving BNO responds by writing its status to the Data Low Register which is read by the resource manager. More information on BNO and on the Data Low Register can be found in the VXIbus System Specification.

If the command module is in a system where it is not the resource manager, it sends BNO to each of its message based servants once it receives BNO from its commander.

VXI SYSFAIL* Line

One of the signals on the VXI backplane is SYSFAIL*. This signal is intended to indicate that some VXI module in the system ha s f ailed. During power-on or rebooting the HP E1406A, VXI modules may briefly generate the SYSFAIL* signal. VXI modules that fail to operate may c ontinue to ge nerate SYSFAIL* after the power-on period as an indication of the f ailure. Similarly, modules that fail during operation of the system ma y a lso generate SYSFAIL* when the failure occurs.

If the HP E1406A Command Module detects the SYSFAIL* after the power-on period, it will automatically reboot. When this occurs, the command module will not enable communicatio n with any of the VXI modules in the system. This is because the HP E1406A cannot determine which VXI module has failed. Also, if IBASIC is installed, it will be disabled. Only the System instrument will be enabled. This behavior is intended to guarantee that you will recognize that a failure has occurred. If this situation occurs, the Error +2129, "Warning, Sysfail detected".

To restore normal operation of the HP E1406A Comm and Mo dule, you must determine which VXI module has failed an d remove it from the system. After removing the failed module and cycling power on you r VXI mainframe, your HP E1406A Comm and Mod ule will work no rmally.

About This Chapter

This chapter shows you how to use the HP E1406A Command Mod ule’s disp lay te rminal in terface to operate instruments in a C-Size mainframe when the Flash ROMS Run/Load swi tch is set to its "Run" position . The instruments (incl udin g the System instrum ent) are disabled when the Flash ROMS Run/Load switch is in the "Load" posit ion.

In this position, a special Loader ins trument is presen t, and will let you download drivers or a new operating system to Flash ROM. The terminal interface uses the built-in RS-23 2 port and/or the optional HP E1324 A RS-232C/422 Terminal Interface for Command Modules to provide a front panel for C-size VXIbus systems.

Terminal Interface Features

Figure 3-1 shows a typical terminal interface display with its function label s across the bottom of the screen. The first five function keys ( f1 through f5) select instrument men u choices. Function keys f6 through f8 provide menu control and access to utility functions. The tutorials in this chap te r show how to use most of the menu control and ut ility function keys. See “General Key Descriptions” on page 77 for a complete description of each of these key functions.

Using Display Terminal Menus

A System instrument menu and a variety of othe r instrumen t menus (depending on the instruments in the command module servant area) are available from the terminal interface. These menus incorporate the most used functions but do not provide a ccess to the complete functio nality of an instrument. If a particular function is not available from a menu, you can type the corresponding common command or SCPI command string and execute it fr om the terminal interface. See “Executing Commands” on page 76 for more information.

62 Using the Display Terminal Interface Chapter 3

When you select an instrument, you are assigning th e terminal interface to that instrument. This means that any menu operations, commands executed or recalled, errors displayed, and so forth pertain only to that instrument. Terminal int erface operation of an instrument is indepen dent from oth er instruments and independent from the remote operation of the instrument . To operate another instrument from the terminal interface, you must select that instrumen t.

be programmed using the SYSTEM instrument menu. See “Using the System Instrument Menu ” on page 65.

In systems with multiple comm and modules, the instruments in the menu depend on the command module whose RS-232 port is connected to the terminal. To change menus (command modules):

1. Move the RS-232 cable to the desired command module.

2. Press the "Ctrl-D" keys on an RS-232 terminal to guarantee that the display terminal interface is in control of the terminal.

3. Type:

ST (followed by Return) for auto-identi fi cation of the te rminal.

ST HP ( fo llowed by Return) for HP terminals - 700/94, 700/92, 26xx, 23xx

Display Terminal

Menu Tutorial

Note: Typical instruments are shown. Actual choices depen d on installed inst ru ment s.

Following the power-on sequence or a system reset, th e screen shows t he Select an instrument menu (see Figure 3-2). This menu allows you to select one of the instruments listed.

Figure 3-2. "Select an Instrumen t" Menu

Figure 3-2 shows the Select an Instrument menu when the Flash ROMS Run/Load switch on th e front of the HP E1406A Comm and Mod ule is set to "Run". If this switch is in the "Load" position , the SYSTEM instrument entry will be replaced by LOADER and the rest of the instruments will disappear from the menu.

The menu select and menu control function keys (usually labeled f1 - f8 on their key caps) are defined by eight function labels located ac ross the bottom of the terminal screen. Once you learn how these keys operate, using the menus is easy (key labels are shown in bold text in this chapte r):

To select a displayed menu choice, press the function key ( f1 - f5) which corresponds to the function key label.

• When there are more than five menu choices, function key f6

becomes labeled MORE. Press MORE to display the next group of choices. By repeatedly pressing MORE you can display all groups of choices. After you have displayed all groups of choices, pressing MORE again returns to the first group of choices.

• Whenever the screen is requesting information (input prompt) such as

Enter the d evice’s logi cal addr ess, just type the information and press Return (m ay be Ent er on a terminal emulator).

If you pressed the wrong menu key and do not want to enter the requested information, you can escape the input prompt and stay at the same menu level by pressing ESC or PRV_MENU.

If you make an incorrect entry in response to an input prompt, the bottom line of the Text Output Area will show an error message. When this happens, just select that menu choice again (f1 - f5 keys), re-type the correct information, and press Return.

• Press PRV_MENU or ESC to return to the previous menu within an

instrument menu or escape from an input prompt. Press SEL_INST to return to the Select an Instrument menu (see next item). Note that when you leave an instrument and return later, you return to the same menu location you were at when you left. Any information below the Text Output Area will also be redisplay ed when you return.

64 Using the Display Terminal Interface Chapter 3

• In addition to the instrument menu keys, CLR_ INST , RST_INST

and SEL_INST are helpful when operatin g instru ments . These and other utility keys are accessed by pressing the UTI LS key (see Figure 3-3). Refer to “General Key Descriptions” on page 77 for

information on the RCL_.... keys in this men u.

– CLR_INST clears the instrument’s terminal interface input and

output buffers (remote buffers are not cleared) and returns to the top level of the instrument m en u. Press CLR_INST whenever an instrumen t is busy, is not responding to terminal in te rface control, or to abort a command bein g ente red from the terminal interface.

– RST_INST clears all terminal interface and remote input and

output buffers and resets the instrument.

– SEL_INST returns you to the Select an Instrument

menu. SEL_INST is the key under the UTILS key. You can easily return to the Select an Instrument menu by pressing f8 twice.

Switchbox

Note After you press the function key for SWI TCH, the screen may show:

The instrument men us allow you to access the most-us ed instrum ent functions or to monitor an instrument (monit or mode) while it is being controlled from remote. The Switchbox menu is used as an example to show you how to use the instrument menu s. Menus are available for many, but not all, instruments . See your instrument user’s man ual fo r more information on a particular instrument’s m en u. The Switchbox menu allows you to:

– Open and close channels – Scan channels – Display module (card) type and description – Reset a selected switch module – Monitor a switchbox

To select the Switchbox, press the functio n key (f1 - f5) which corresponds to the label SWITCH in th e Select an instrument menu. (If the

Select an instrument menu is not being displayed press UTILS then SEL_INST.)

Select SWITCH at logical address:_ while the function key labels show two or more logical addresses. This means more than one switchbox is installed in the mainframe. To select one of the switchboxes, press the function key for the logical address key label .

Figures 3-10 through 3-13 show how to us e the switchbox menu. Keep the following points in mind when usin g the menu:

• The card number identifies a module within the switchbo x. The

module with the lowest logi cal address is always card number 01. The module with the next successive logi cal address is card number 02, and so on.

• The @ character is required preceding a channel list when executing

a switchbox command from the terminal in te rface or remote. When entering a channel list in response to a menu prompt, however, do not precede it with the @ character. Doing so causes a syntax error.

The error message will be displayed in the bottom line of the Text Output Area. To see if another error was logged, repeat the by pressing UTILS, RCL _PREV, then Return.

After you have read all the error messages, executing the command causes the screen to show: +0,"No error". After reading the error message(s), press the f1 key to return to monitor mo de.

Executing Commands

From the terminal int erface, you can type and execute IEEE 488.2 common commands and SCPI commands for the instrument presently selected by the Select an instrument menu. (However, you cannot execute a command when the screen is requesting that you inp ut informat ion. ) This is particularly useful for accessing functions not availab le in an instrument’s menu. For example, assume you want to progr am the HP E1411B 5 Multimeter for 10 DC voltage measurements. To specify 10 measurements you must type in the necessary command since the command is not on the multimeter menu. After selecti ng the VOLTMR menu, type the following commands and press the Return key after each command .

This section discu sses usi ng termin als which are not on the Supported Terminals list. Primaril y this section is to help you us e terminals which do not provide programmable soft keys (functio n keys). Without this capability, a terminal cannot access the display termin al interface’s menus. Instead, the terminal interface provides a set of terminal interface commands which allow you to select instrum en ts by name or logi cal address. Once selected, you can type common commands or SCPI commands to the instrument. In addition , keyboa rd accessibl e control codes provide display control for term inals whi ch may not have keys dedi cated to those functions.

What “Not

Supported” Means

Testing Terminals

for Compatibility

Strictly speaking, a terminal is not supported if it has not been rigorousl y tested with the display terminal in t erface. There are several HP terminals which may be compatible with the terminal in terface. Terminals such as the DEC VT100, DEC VT220, and WYSE WY-50, or emulati ons of these may also work properly with the terminal interface. If you have one of these terminals, try it. Here is a list of terminals you should try.

– HP 2392A – H P 2394A – DEC VT100 – DEC VT220 – WYSE WY-50 – HP AdvanceLink terminal emulation software (configure as

HP 2392A )

Here is how you test an unsuppo rted terminal for com patib ilit y with the display terminal interface:

1. Connect your terminal and configure its communication parameters to match the mainframe’s serial interface (see Appendix C).

2. With your terminal turned on and set to "remote mode" , turn on the mainframe. After the mainframe power-on self-test, the display interface sends sequences of characters to your terminal which should cause it to return its identification. If the terminal ID matches one in a list kept by the terminal interface, it will send character sequences to program the function keys and their labels.

3. If you now see the Select an instrument prompt and the Select an instrument menu labels, your terminal is ready to try. Go to the beginning of this chap ter and try the men us.

82 Using the Display Terminal Interface Chapter 3

4. If you see only the Select an instrument prompt without the Select an instrument menu labels, your terminal did not

return a recognized ID. To set the terminal type manually, type the terminal interface command:

ST HP ( fo llowed by Return) for HP terminals - 700/94, 700/92, 26xx,23xx

ST HP70043 (follow ed by Return) for the HP 700/43 terminal

ST VT100 (followed by Return) for VT100 emulat ors

ST VT220 (followed by Return) for VT220 emulat ors

ST WYSE30 (follow ed by Return) for WY-30 emulators

ST WYSE50 (follow ed by Return) for WY-50 emulators

If you now see the Select an instrument menu labels, go to the beginning of this chapter and try the menus.

Turn the mainframe off and then on again.

Continue with this chap te r to learn how to use your terminal without men us.

Using a Terminal

Witho ut Menus

You can still control instrum en ts installed in yo ur mainframe without using the terminal interface menus. In this case you will send comm on comm ands and SCPI commands to your inst ru ments by typing them on your terminal keyboard, or through a computer interface.

Selecting Instruments To send commands to, and receive responses from an instrument, you must

first select that instrument. Two commands are provided to select instruments. They are These commands only work from the Select an instrument prompt. The commands can be typed in upper case or lower case.

SI (Select Instrument), and SA (Select Address).

SI Command SI selects an instrument by its name, exactly as it would appear in the

Select an instrument menu (see Table 3-2). If your mainframe has more than one instrum ent with th e same name, follow the nam e with a comma (,) and the desired instrument’s log ical address . Here are some examples of

SI co mmands:

• si voltmtr (selects a voltmeter instrument)

• si switch (selects a switch box in strum en t)

• SI SWITC H (same as abo v e)

• si switch,16 (selects swit chbox at logical address 16)

To get a list of the logical address es used in your mai nf rame, send th e SCPI command determine what instrument is at each logical address, send the command

Control Sequences for

Terminal Interface

Functions

The terminal interface provides the keyboard control sequences list ed in Table 3-3. These can be thought of as keyboard short-cuts for compatible terminals (those which provide menu capabili ty). Only those functions in the table marked with * (asterisk) operate for “UNKNOWN” terminal types (those which do not support menus ). An “UNKNOWN” terminal type has very limited editing capabili ty. It will not support th e EDIT mode for the optional IBASIC interpreter. In the following table, † = IBASIC only.

For some commands used by the menus, the data entered is appended to a command header. For example, if you enter "1" as the port number for a digital I/O module, the command used is DIG:HAND1:MODE NONE where HAND1 indicates the port number. If your entry was invalid or incorrect, error -113 occurs.

An unassigned device (incorrect logical address) was detected., If you cycle power or perform system reset, the display will show the logical address of the unassigned device. You can also check the logical addresses using the CONFIG? -- LADDS branch of the System instrument menu. You can also use SYST:ERR? in the system instrum ent.
