VX4380 256-Crosspoint Relay Matrix Module User Manual vii Preface viii VX4380 256-Crosspoint Relay Matrix Module User Manual Getting Started Getting Started This section begins with a brief description of the VX4380 256-Crosspoint Relay Matrix Module, and explains how to configure and install the module in a VXIbus mainframe. The quick functional check, also included in this section, assures that the instrument operates properly. Product Description The VX4380 256-Crosspoint Relay Matrix Module is a printed circuit board assembly for use in a mainframe conforming to the VXIbus Specification. The VX4380 provides four 4 × 16 2-wire matrix sections. Each section can be configured to connect either the four rows or the sixteen columns to the section above or below it to produce up to a 16 × 16 2-wire matrix or a 4 × 64 2-wire matrix. The VX4380 provides the following features: H high density single slot VXI relay matrix module with four 2-wire matrices H 2 A switching maximum current per contact H 220 VDC, 250 VAC maximum switching voltage per contact H 60 W, 125 VA maximum switching power per contact H latching relays for low-power, low-noise operation H two 160-pin DIN front panel connectors H low-cost VXI local bus slave interface H Option 01 – this option enables the VX4380 to control up to 11 additional relay modules from the Tektronix family of relay modules. These modules are controlled via the VXI P2 local bus. H > 15 MHz bandwidth (– 3 dB) for 4 × 16 2-wire matrix H > 15 MHz bandwidth (– 3 dB) for 16 × 16 2-wire matrix User control of the VX4380 is achieved by installing the Option 01 VXI Interface daughter board. This daughter board may be installed on the VX4380 or on another Tektronix compatible relay module which is installed in a VXI chassis slot to the left of the VX4380. The Option 01 daughter board acts as a VXI servant to a VXI bus commander. The VXI bus commander sends SCPI compatible commands to the Option 01 daughter board using VXI word serial protocol. The Option 01 daughter board in turn controls the VX4380 on which it is installed and controls additional relay modules installed in adjacent slots to its right via the VXI P2 local bus. The daughter board is capable of controlling from VX4380 256-Crosspoint Relay Matrix Module User Manual 1–1 Getting Started one to 12 relay modules including members of the SurePatht family of relay switching modules and VX4372 and VX4374 Scanner Slave modules. In this document, these modules will be referred to as “local bus slaves.” The Option 01 VXI Interface Module includes the following features: H CPU: Zilog Z88C00 Microcontroller with 20 MHz clock 64 Kbyte of EPROM and 32 Kbyte of RAM H VXI Interface: VXI Rev 1.4 Message Based Device Supports Fast Handshake word serial protocol data transfers IEEE-488.2 device Logical Address selectable with two rotary hexadecimal switches Interrupter level selectable with a rotary hexadecimal switch. Selects one of seven levels or disables interrupt generation Command programmable control of one to eight VXI TTL trigger Command programmable monitoring of one of eight VXI TTL triggers The Local Bus Interface provides serial I/O interface for control of VX4372 and VX4374 Scanner Slave and SurePatht relay modules, monitors the power fuses of all local bus slave modules that it controls, and provides a serial input interface to identify each local bus slave that it controls. As part of the self test, SurePatht modules automatically verify the control logic every time a relay operation is performed. Figure 1–1 shows a functional block diagram of the VX4380. Figure 1–2 shows a typical SurePatht configuration. 1–2 VX4380 256-Crosspoint Relay Matrix Module User Manual Getting Started Join Rows 1–4 4 x 16 = 4 ... 3 ... 2 ... 1 ... 1 2 3 Section 4 4 x 16 2-Wire Join Cols 3–4 Join Rows 3–4 Section 3 4 x 16 2-Wire Join Rows 2–3 Join Cols 2–3 16 Section 2 4 x 16 2-Wire = Join Rows 1–2 Join Cols 1–2 Section 1 4 x 16 2-Wire Matrix 1 2 3 4 4 x 16 4 x 16 4 x 16 4 x 16 4 x 16 4 4 x 16 3 4 x 64 2 4 x 16 4 x 16 3 4 x 16 2 1 4 x 16 4 x 16 4 4 x 16 1 8 x 32 16 x 16 Figure 1–1: VX4380 Functional Block Diagram VX4380 256-Crosspoint Relay Matrix Module User Manual 1–3 Getting Started VXI interface & slave controller daughter board Backplane connectors Front panel connectors VXI backplane local bus Daughter board connectors Figure 1–2: Typical SurePath Configuration Fuses The VX4380 Module has one 10 A fast-acting fuse on the +5 V line. Each relay module that the Option 01 Module controls has a fuse that limits the amount of current that the module can draw from the VXI backplane +5 V power pins. This fuse protects the module in case of an accidental shorting of the power bus or any other situation where excessive current might be drawn. The Option 01 Module monitors the state of the fuses of each of the relay modules that it controls. If a fuse opens on one of these modules, the Option 01 Module will assert SYSFAIL* on the VXIbus. If the +5 V fuse on the module on which the Option 01 Module is installed opens, the VXIbus Resource Manager will be unable to assert SYSFAIL INHIBIT on the Option 01 to disable SYSFAIL*. If a +5 V fuse opens, remove the fault before replacing the fuse. Replacement fuse information is given in the Specifications section of the user manual for the appropriate relay module. 1–4 VX4380 256-Crosspoint Relay Matrix Module User Manual Getting Started LEDs BITE (Built-in Test Equipment) The following LEDs are visible at the top of the VX4380 Module’s front panel to indicate the status of the module’s operation (see Figure 1–5). Power LED indicates power is applied to the module Failed LED indicates the module is in the FAILED state Built-in Test Equipment (BITE) is provided by extensive self tests that are automatically invoked on power-on and can also be invoked on command. Circuitry tested includes the CPU and all memory, and the relay control circuitry on each relay module controlled by the Option 01. Accessories Table 1–1 lists the standard accessories included with the VX4380. Table 1–1: Standard Accessories Accessory Part Number VX4380 User Manual 070-9182-XX VX4380 Reference 070-9202-XX Table 1–2 lists the options available for the VX4380. Table 1–2: Options Option Part Number 01 VXI Interface Kit 040-1510-XX Controls and Indicators The following controls are provided to select the functions of the VX4380 operating environment. Figures 1–3 and 1–4 illustrate the physical location of these controls and indicators. Switches The Logical Address switches and VMEbus Interrupt Level Select switch must be correctly set to insure proper operation. See Configuration for details on how to set the switches. VX4380 256-Crosspoint Relay Matrix Module User Manual 1–5 Getting Started LOGICAL ADDRS LO Option 01 HI INTRPT Switches as viewed from the rear of instrument (labels are on the back shield) F1291 Figure 1–3: VX4380 Connectors, Indicators, and Switch Locations Figure 1–4: VX4380 Front Panel 1–6 VX4380 256-Crosspoint Relay Matrix Module User Manual Getting Started Configuration The following switches must be correctly set to ensure proper operation. Refer to Figure 1–3 for their physical locations. Logical Address Switches Each functional module in a VXIbus System must be assigned a unique logical address, from 1 to decimal 255 (hexadecimal FF). The base VMEbus address of the VX4380 is set to a value between 1 and hexadecimal FF (FF16) by two hexadecimal rotary switches. Align the desired switch position with the arrow on the module shield. The physical address of the instrument is on a 64 byte boundary. If the Logical Address switch representing the most significant digit (LA-HI) of the logical address is set to position X and the switch representing the least significant digit (LA-LO) of the logical address is set to position Y, then the base physical address of the VX4380 will be [(4016 × XY16) + C00016]. For example: Base Physical Address L.A. HI LO decimal hex A16 016 A16 (64 * 10) + 49152 = 49792 (4016 * A16) + C00016 = C28016 1516 116 516 (64 * 21) + 49152 = 50496 (4016 * 1516) + C00016 = C54016 LA. is the Logical Address IEEE-488 Address In order to use and program the VX4380 Module in an IEEE-488 environment you must know the IEEE-488 address of the module. Different manufacturers of IEEE-488 interface devices might have different algorithms for equating a logical address with an IEEE-488 address. Consult the operating manual of the IEEE-488 Interface Module being used. VMEbus Interrupt Level Select Switch Each function module in a VXIbus System can generate an interrupt at a specified level on the VMEbus to request service from the interrupt handler located on its commander. Set the interrupt level to the same level as the interrupt handler on that commander. The VMEbus interrupt level on which the VX4380 Module generates interrupts is set by a rotary switch. Align the desired switch position with the arrow on the module shield. Valid VMEbus Interrupt Level Select switch settings are one through seven, with setting one equivalent to level one, and so on. The level chosen should be the same as the level set on the VX4380 interrupt handler, typically the module commander. Setting the switch to zero or eight will disable the module interrupts. Do not use switch settings nine through f. VX4380 256-Crosspoint Relay Matrix Module User Manual 1–7 Getting Started Interrupts are used by the module to return VXIbus Protocol Events to the module commander. Refer to the Operating Basics section for more information on interrupts. The VXIbus Protocol Events supported by the module are listed in Appendix A: Specifications. Installation This section describes how to install the VX4380. Tools Required Requirements and Cautions A slotted screwdriver set is required for proper installation. The VX4380 Module is a C-size VXIbus instrument module and therefore may be installed in any C- or D-size VXIbus mainframe slot other than slot 0. To install the module in a D-size mainframe, consult the operating manual for the mainframe. Refer to Configuration for information on selecting and setting the Logical Address switch of the module. This switch defines the programming address of your module. To avoid confusion, it is recommended that the slot number and the logical address be the same. NOTE. Note that there are two printed ejector handles on the card. To avoid installing the card incorrectly, make sure the ejector marked “VX4380” is at the top. Verify that the mainframe is able to provide adequate cooling and power with this module installed. Refer to the mainframe Operating Manual for instructions. If the VX4380 is used in a Tektronix mainframe, all VX4380 cooling requirements are met If the VX4380 is inserted in a slot with any empty slots to the left of the module, the VME daisy-chain jumpers must be installed on the backplane in order for the VXI Module to operate properly. Check the manual of the mainframe being used for jumpering instructions. Jumpers are not necessary for autoconfiguring backplane designs. 1–8 VX4380 256-Crosspoint Relay Matrix Module User Manual Getting Started Installation Procedure Follow these steps to install the VX4380. If the module has Option 01, first refer to the Option 01 User Manual for instructions on mounting the option. CAUTION. The VX4380 Module is a piece of electronic equipment and therefore has some susceptibility to electrostatic damage (ESD). ESD precautions must be taken whenever the module is handled. 1. Record the revision level, serial number (located on the label on the shield of the VX4380), and switch settings on the Installation Checklist. 2. Verify that the switches are set to the correct values. Refer to Configuration for more information on setting switches. 3. Make sure that the mainframe power is off. 4. Insert the module into one of the instrument slots of the mainframe (see Figure 1–5). 5. Cable Installation: Use the correct cable to interface between the module I/O connector and the Unit Under Test (UUT). The recommended cable is listed in Appendix A: Specifications. Figure 1–5: Module Installation VX4380 256-Crosspoint Relay Matrix Module User Manual 1–9 Getting Started Installation Checklist Installation parameters will vary depending on the mainframe being used. Be sure to consult the mainframe operating manual before installing and operating the module.

Self Test The VX4380 256-Crosspoint Relay Matrix Module executes a self test at power-on, on direction of a VXIbus hard or soft reset condition, or on command. The power-on self test consists of an interface self test and an instrument self test. The self test requested by command performs only the instrument self test. A VXIbus hard reset occurs when another device, such as the VXIbus Resource Manager, asserts the backplane line SYSRESET*. A VXIbus soft reset occurs when another device, such as the VX4380 commander, sets the Reset bit in the VX4380 Control register. During power-on, or a hard or soft reset, the following actions take place: 1. The SYSFAIL* (VME system-failure) line is set active, indicating that the module is executing a self test, and the Failed LED is lighted. For a soft reset, SYSFAIL* is set. All Tektronix commanders will simultaneously set SYSFAIL INHIBIT to prevent the resource manager from prematurely reporting the failure of a card. 2. On completion of the interface self test, SYSFAIL* is de-asserted. If the test fails, the SYSFAIL* line remains active. If the interface self test passed, the SYSFAIL* line is released, and the module enters the VXIbus PASSED state (ready for normal operation). If it failed, the module enters the VXIbus FAILED state. 3. The instrument self test, as described in the *TST? command description, is then executed. This tests the Option 01 VXI Interface daughter board and any relay modules under its control. If the self test fails, the module makes an internal record of the failure(s) that occur. The default condition of the Option 01 Module after the completion of power-on self test is as follows: All relays on modules controlled by the Option 01 (except VX4320 Modules) are set to the open position. You can run the self test at any time during normal operation by using the *TST? command. At the end of a self test initiated by this command, the module is restored to its pre-test state. VX4380 256-Crosspoint Relay Matrix Module User Manual 1–11 Getting Started During a commanded self test: 1. SYSFAIL* is not asserted. 2. The module executes the same instrument self test as is executed upon power on. 3. When the self test is completed, the modules controlled by the Option 01 are restored to their pre-test state. Operational Check An operational check of the VX4380 may be performed by checking the continuity of the switch closures using an ohmmeter or a test light. When equipped with the Option 01 VXI Interface, the commands will open all of the relay paths. All relays on the VX4380 will also be opened automatically on power-on. Figure 1–1 VX4380 Functional Block Diagram shows the configuration of the VX4380 with all paths open. Refer to Appendix B: Input/Output Connections for the connector pinouts and the Functional Block Diagram. Use a continuity tester to verify that all rows are open to all columns. Will close the 2-wire switch path from row 1 of section 1 to column 1 of section 1 (Row01Lo of Section 1 to Col01Lo of Section 1, and Row01Hi of Section 1 to Col01Hi of Section 1). Check the continuity. Be careful to prevent damage to the pins of the front panel connectors. Note that true measurement of the resistance of the path requires a high-resolution instrument and special procedures which are beyond the scope of this check. Use the commands and to open the previous path and close the 2-wire switch path from row 1 of section 1 to column 2 of section 1. Check for continuity of the two paths. Use the commands and 1–12 VX4380 256-Crosspoint Relay Matrix Module User Manual Getting Started incrementing r (the row number) from 1 through 4 for each value of c and s while incrementing c (the column number) from 1 through 16 for each value of s (the section number) from 1 through 4 to close the two-wire switch path from row r to column c of each section s. Check for continuity of the two paths each time. By testing in this manner, it can be verified that the module is operational. SYSFAIL* Operation SYSFAIL* becomes active during power-on, hard or soft reset, or self test, or if the module loses any of its power voltages. When the mainframe Resource Manager detects SYSFAIL* set, it will attempt to inhibit the line. This causes the VX4380 256-Crosspoint Relay Matrix Module to deactivate SYSFAIL* except when +5 V power is lost on the relay module on which it is installed. VX4380 256-Crosspoint Relay Matrix Module User Manual 1–13 Getting Started 1–14 VX4380 256-Crosspoint Relay Matrix Module User Manual Operating Basics Operating Basics The VX4380 256-Crosspoint Relay Matrix Module is a VXIbus message-based instrument and communicates using the VXIbus Word Serial Protocol. The module is programmed by issuing ASCII characters from the system controller to the VX4380 via the module VXIbus commander and the VXIbus mainframe backplane. Refer to the manual for the VXIbus device that will be the VX4380 Module commander for details on the operation of that device. If the module commander is a Tektronix IEEE-488 Interface Module, refer to the operating manual for the module and Appendix C: Examples in this manual for information on how the system controller communicates with the commander being used. Functional Overview The VX4380 256-Crosspoint Relay Matrix Module provides four 4 × 16 2-wire matrix sections. Each section can be configured to connect either the four rows or the sixteen columns to the section above or below it to produce up to a 16 × 16 2-wire matrix or a 4 × 64 2-wire matrix. Power-on The instrument runs its self test and is ready for programming five seconds after power-on. The VXIbus Resource Manager can add an additional delay. The Power LED of each relay module controlled by the Option 01 will be on. The Failed LED on each of these modules will be off. The default condition of the module after power-on is listed in the *RST command description. Self-test failures are described in the *TST command description. The format and syntax for the command strings are described in the Command Syntax section. A complete description of each command in alphabetical order is in the Command Descriptions section. VX4380 256-Crosspoint Relay Matrix Module User Manual 2–1 Operating Basics Instrument I/O: VXIbus Basics NOTE. If the user’s mainframe has other manufacturers’ computer boards operating in the role of VXIbus foreign devices, the assertion of BERR* (as defined by the VXIbus Specification) may cause operating problems on these boards. The Option 01 Module installed on a switching module is a C-size single slot VXIbus Message-Based Word Serial instrument. It uses the A16, D16 VME interface available on the backplane P1 connector and does not require any A24 or A32 address space. The module is a D16 interrupter. The Option 01 is neither a VXIbus commander nor a VMEbus master; therefore it does not have a VXIbus Signal register. The Option 01 is a VXIbus messagebased servant. The module supports the Normal Transfer Mode of the VXIbus using the Write Ready, Read Ready, Data In Ready (DIR), and Data Out Ready (DOR) bits of the module Response register. A Normal Transfer Mode read of the Option 01 proceeds as follows: 1. The commander reads the Option 01 Response register and checks if the Write Ready and DOR bits are true. If they are, the commander proceeds to the next step. If not, the commander continues to poll these bits until they become true. 2. The commander writes the Byte Request command (hexadecimal 0DEFF) to the Data Low register of the Option 01. 3. The commander reads the Option 01 Response register and checks if the Read Ready and DOR bits are true. If they are, the commander proceeds to the next step. If not, the commander continues to poll these bits until they become true. 4. The commander reads the Option 01 Data Low register. A Normal Transfer Mode write to the Option 01 proceeds as follows: 1. The commander reads the Option 01 Response register and checks if the Write Ready and DIR bits are true. If they are, the commander proceeds to the next step. If not, the commander continues to poll the Write Ready and DIR bits until they are true. 2. The commander writes the Byte Available command which contains the data (hexadecimal 0BCXX or 0BDXX, depending on the End bit) to the Data Low register of the Option 01. 2–2 VX4380 256-Crosspoint Relay Matrix Module User Manual Operating Basics The module also supports the Fast Handshake Mode during readback. In this mode, the module is capable of transferring data at optimal backplane speed without needing the commander to test any of the handshake bits. The Option 01 asserts BERR* to switch from Fast Handshake Mode to Normal Transfer Mode, per VXI Specification. The Option 01 Read Ready, Write Ready, DIR and DOR bits react properly, in case the commander does not support the Fast Handshake Mode. A Fast Handshake Transfer Mode read of the Option 01 proceeds as follows: 1. The commander writes the Byte Request command (hexadecimal 0DEFF) to the Option 01 Data Low register. 2. The commander reads the Option 01 Data Low register. A Fast Handshake Transfer Mode write of the Option 01 proceeds as follows: The commander writes the Byte Available command which contains the data (hexadecimal 0BCXX or 0BDXX, depending on the End bit) to the Data Low register of the Option 01. The commander may immediately write another Byte Available command without having to check the Response register. The module has no registers beyond those defined for VXIbus message based devices. All communications with the module are through the Data Low register, the Response register, or the VXIbus interrupt cycle. Any attempt by another module to read or write to any undefined location of the Option 01 address space may cause incorrect operation of the module. As with all VXIbus devices, the Option 01 has registers located within a 64 byte block in the A16 address space. The base address of the Option 01 device registers is determined by the device unique logical address and can be calculated as follows: Base Address = V16 * 4016 + C00016 where V is the device logical address as set by the Logical Address switches. Configuration Registers Table 2–1 lists the Configuration registers and a complete description of each register. The offset is relative to the module base address.

The is optional white space, followed by any one of the following command terminations: a line feed or new line character (hexadecimal 0A, decimal 10) the END bit set the END bit with a line feed or new line The command string is buffered until the terminator is encountered, at which time the entire string is processed. H In addition to terminating a command, the semi-colon character directs the SCPI command parser to interpret the next command with the assumption that all characters up to and including the last colon in the previous command have just been parsed. In the following example, the Option 01 is installed on a VX4380 Module. Two additional VX4380 Modules are installed in consecutive slots to the right of the first VX4380. Under these conditions, the commands cause all relays on all three VX4380 Modules to open. Note that each of these commands is terminated by a line feed. An equivalent method of sending these commands using the semi-colon character as a terminator is After a line feed or END bit is used to terminate a command, the parser no longer makes the assumption described above. Thus, after the command is parsed, the command is no longer valid. VX4380 256-Crosspoint Relay Matrix Module User Manual 3–1 Command Syntax In the next example, the Option 01 is installed on a VX4330 Module. Two additional VX4330 Modules are installed in consecutive slots to the right of the first VX4330. The commands connect the commons of sections 1 through 6 on the first VX4330, sections 1 and 2 on the second VX4330 and sections 1 through 4 on the third VX4330. An equivalent way to send these commands using the semi-colon as a terminator is Note that in these examples represents a single line feed character. H White space characters can be used to make a command string more readable. These characters are ASCII-encoded bytes in the range hexadecimal 00-09 and 0B-20 (decimal 0-9 and 11-32). This range includes the ASCII control characters and the space, but excludes the line feed . White space characters are ignored when legally encountered in a command string. White space is allowed anywhere in a command string, except for the following: Within a program mnemonic ( for example RO UTE ) Around a colon (:) mnemonic separator (for example ROUTE: CLOSE or ROUTE :CLOSE) Between a mnemonic and a (?) (for example CLOSE ?) Following an asterisk (*) (for example * STB?) Within a number (for example 12 34) Within a module name specified in a [ROUTe:]MODule[:DEFine] command (for example ROUTE:MODULE:DEFINE RFM UX, 1). At least one white space character is required between a command/query header and its associated arguments. For example in the command the command header is the string “route:configure:join”. The arguments associated with this command are the module name “m1” and the section list “(1:6)”. At least one white space character must be sent before the first argument. 3–2 VX4380 256-Crosspoint Relay Matrix Module User Manual Command Syntax In the query )',+ $'* % the query header is the string “route:close?”. The argument associated with this query is the channel list “(@m1(1:64))”. At least one white space character must be sent before the channel list argument. Syntax Example H All characters in a command can be sent in either upper or lower case form. H Multiple data parameters passed by a command are separated by a comma (,). H A question mark (?) following a command indicates that a response will be returned. All responses from the module are terminated with a carriage return and a line feed (hexadecimal 0A) character. H In the command descriptions, the following special characters are used. Except for the colon (:), these characters are not part of the command and should not be sent. If an optional field is omitted, the default for the command is applied. [] Brackets indicate an optional field | A bar indicates a logical OR choice : A colon is used to separate command fields <> Field indicator Capital letters indicate the minimum required characters which need to be sent. Lower case letters are optional. For example, the syntax of the trigger source command is given as ! ), & - - # + - )!& Each of the following is a valid form of this command: +)#!! )* (, & *',) ,* +)#!* (*',) "'$ )#! )#!',) )#!',) )#!! )',) %% # + VX4380 256-Crosspoint Relay Matrix Module User Manual 3–3 Command Syntax SCPI/IEEE 488.2 Command Elements The definition of elements used in SCPI/IEEE 488.2 commands and command descriptions is as follows: ASCII integer representation of a decimal number. ASCII integer, fixed point or floating point representation of a decimal number. A user-defined ASCII string to be associated with the local bus address of a relay module. strings must start with a letter and may consist of alphanumeric characters, underscores, and digits. The maximum length of a is 12 characters. One or more ASCII strings separated by “!” characters that specify a relay on a relay module. The format of a field for each of the SurePath relay modules is: H VX4320 RF Multiplexer: ! The range of the first field is 1 to 4. This field specifies a relay within one of the sections of the VX4320. The range of the second field is 1 to 8. This field specifies a section of the VX4320. A one-dimensional may also be used to specify a channel on a VX4320 Module. The one-dimensional is given by the formula: ( (section – 1 ) × 4 ) + relay. where variables “section” and “relay” are section and relay numbers specified in a two-dimensional . H VX4330 Scanner/Multiplexer: ! The first field specifies a relay within the specified section. The range of this field depends on the current configuration of the section of the VX4330 specified in the second field. The range of the second field is 1 to 6. This field specifies a section of the VX4330. 3–4 1 – 10 4-wire 1 – 20 4-wire independent 1 – 20 2-wire 1 – 40 1-wire VX4380 256-Crosspoint Relay Matrix Module User Manual Command Syntax H VX4350 General Purpose Switching module: The range of this field is 1 to 64. It specifies one of 64 relays on the VX4350. H VX4380 Matrix: ! ! The range of the first field is 1 to 4. It specifies the row of a relay in one of the sections of the VX4380. The range of the second field is 1 to 16. It specifies the column of a relay in one of the sections of the VX4380. The range of the third field is 1 to 4. It specifies a section of the VX4380. A one dimensional may also be used to specify a channel on a VX4380 Module. The one dimensional is given by the formula: ( (section – 1 ) × 64 ) + ( ( row – 1 ) × 16 ) + column where variables “section” and “row” and “column” are section, row, and column numbers specified in a three-dimensional . Channel_list> A list of channel numbers on one or more relay modules. The limits on the channel numbers in a depend on the model number of the relay module(s) specified in the . The syntax of a is shown in the following diagram: A module_name is an ASCII string that has been associated with a relay module in a ROUTe:MODule:DEFine command. A channel_range may consist of a single or a range of s. A range of s is indicated by two s separated by a colon (:) character. A may have one, two or three dimensions depending on the architecture of the relay module it applies to. VX4380 256-Crosspoint Relay Matrix Module User Manual 3–5 Command Syntax The following are examples of valid s for Tektronix VX4320, VX4330, VX4350, VX4372, VX4374, and VX4380 relay modules. In these examples it is assumed that the Option 01 is installed on a VX4320 Module. A VX4330, VX4350, VX4372, VX4374, and VX4380 are installed in consecutive slots to the right of the VX4320. The default module names for the VX4320, VX4330, VX4350, VX4372, VX4374 and VX4380 in this example are m1, m2, m3, m4, m5, and m6 respectively. These module names may be overridden by specifying new module names with the [ROUTe:]MODule[DEFine] command. It is also assumed in these examples that all sections on the VX4330 Module have been configured as 10-to-1 4-wire scanners. 3–6 Channels Specified Channel number 1 of section 2 on the VX4320 Module. Channel number 4 in section 1 and relay number 3 in section 8 of the VX4320 Module. Channel number 4 in sections 1 through 8 on the VX4320 Module. Channel number 4 in sections 1 through 8 on the VX4320 Module. Channel 1 in section 6 of the VX4330 Module. All channels on the VX4330 Module in the following order: 1!1, 1!2, 1!3, 1!4, 1!5, 1!6, 2!1, 2!2, 2!3, 2!4, 2!5, 2!6, ... , 10!1, 10!2, 10!3, 10!4, 10!5, 10!6. All 10 channels in section 3 of the VX4330. All 64 channels on the VX4350 Channels 1, 2, 3, 10, 11, and 20 through 13 on the VX4350. Channel 1 in section 2 of the VX4372. Channel 3 in section 1 of the VX4374. The channel that connects row 1 to column 13 in section 3 of the VX4380. The channel that connects row 1 to column 1 in section 2 of the VX4380. Same as the previous example. The channels that connect columns 1 through 16 to row 1 in section 1 of the VX4380. Same as the previous example. Channels 1!1!1, 1!1!2, 1!1!3, 1!1!4, 1!2!1, 1!2!2, 1!2!3, 1!2!4, 1!3!1, 1!3!2, 1!3!3, 1!3!4, 2!1!1, 2!1!2, 2!1!3, 2!1!4, 2!2!1, 2!2!2, 2!2!3, 2!2!4, 2!3!1, 2!3!2, 2!3!3, 2!3!4 on the VX4380 Module. VX4380 256-Crosspoint Relay Matrix Module User Manual Command Syntax As the syntax diagram shows, channels on more than one relay module may be specified in a . The next example specifies channels on three different relay modules. Channels Specified (@m1(1!1), m2(4!6), m6(3!13!2)) Channel 1 of section 1 on the VX4320, Channel 4 of section 6 of the VX4330, and the channel on the VX4380 that connects row 3 to column 13 in section 2. A list of to be executed on one or more relay modules. The syntax of a is supported on the VX4350 and VX4380 modules and is described by the following diagram: , , , ( @ ( ) ) Each is identified by the @ character and represents a single location in the scan sequence. The syntax contains a list of channels that are operated simultaneously when the single location in the scan sequence is reached. A maximum of eight channels may be specified in each . As mentioned above, the module names used in s may be specified with a [ROUTe:]MODule[:DEFine] command. The command route:module:Define rfmux, 1 changes the module name assigned to the VX4320 to “rfmux”. The following can then be used to specify channels on the VX4320. (@rfmux(3!1,2!2)) specifies channel 3 in section 1 and channel 2 in section 2 of the VX4320. The order in which channels are specified is important in the [ROUTe:] CLOSE? and [ROUTe:]OPEN? queries. The states of the channels are returned in the same order that the channels are specified in the . VX4380 256-Crosspoint Relay Matrix Module User Manual 3–7 Command Syntax The order in which channels are specified is also important in the [ROUTe:] SCAN command. This determines the order in which the relays will be closed each time a trigger event is detected. The order in which channels are specified in a is important in the [ROUTe:]CLOSe command when channels in the same section of a VX4320 or a VX4330 are specified. A VX4320 can close only one channel in a section. If a [ROUTe:]CLOSE command specifies more than one relay in a section of a VX4320, the last channel in the will be closed. For example, the command close (@m2(1!1,2!1)) will close channel 2 of section 1 of the VX4320. A VX4330 can close only one channel in a group of joined sections that have been specified in a [ROUTe:]CLOSe:MODe SCAN, , command. If more than one channel in such a group of sections is specified in a [ROUTe:]CLOSe command, the last channel specified will be closed. For example, the commands route:configure:join m2,(1:6) route:close:mode scan,m2,(1:6) join the commons of all six sections of the VX4330 Module and set the mode of the [ROUTe]:CLOSE to scan mode for all six sections of the VX4330. The command route:close (@m2(1!1,1!6)) will then result in channel 1 of section 6 being closed and all other channels on the module being opened. output queue The Output queue of the Option 01 VXI Interface is used to return replies to queries received by the interface. Bit 4 (the MAV bit) of the Status Byte register is set to indicate that this queue is not empty. The DOR bit in the VXI Response register is also set to indicate that this queue is not empty. The commander of the Option 01 VXI Interface monitors the DOR bit to determine when it may read a message from the Output queue. .

When the command parser detects a syntax error or data range error, it places an error message describing the error in the Error/Event queue. Bit 2 of the Status Byte Register is set to indicate that this queue is not empty. Bit 5 of the Standard Event Status Register (the Command Error bit) is set if the parser detects a syntax error. Bit 4 of the Standard Event Status register (the Execution Error bit) is set if the parser detects a numeric argument that is out of range. When a SYSTem:ERRor? query is received, an error message is dequeued from the Error/Event queue and placed in the Output queue. VX4380 256-Crosspoint Relay Matrix Module User Manual 3–9 Command Syntax 3–10 VX4380 256-Crosspoint Relay Matrix Module User Manual Functional Command Groups This section lists the VX4380 system and module commands. System Commands The following low-level commands are typically sent by the module’s commander, and are transparent to the user of the module. (An exception is the Read STB command, which is sent whenever a Serial Poll on an IEEE-488 system is performed.) Most commanders or Slot 0 devices have specific ASCII commands that cause the commander to send one of these low-level commands to a specified instrument. Refer to the operating manual of the commander or Slot 0 device for information on these commands. Command Effect Begin Normal Operation The module begins operation if it has not already done so. Byte Available Transfers module commands to this module. Byte Request Requests the module to return a byte of data from the output queue. Clear The module clears its VXIbus interface and any pending commands. Current module operations are unaffected. Clear Lock Clears the Lock bit of the Response register. Read Protocol The module returns its protocol to its commander. Read STB The module returns its VXI status byte to its commander. Set Lock Set the Lock bit of the Response register. Trigger Close the next relay in a scan list that has been defined by a ROUTe:SCAN command. A VXI Trigger command is enabled as a trigger source by a ROUTe:SEQuence:SOURce BUS command.

The following example defines a scan sequence of 10 relays. The sequence is aborted after the third relay in the sequence is closed. In this example, module names m1 and m2 refer to VX4380 Modules. After a scan sequence is aborted, triggers are no longer accepted by the Option 01 until another INITiate[:IMMediate] command is received. Command Response Define a scan sequence. This command disables the following trigger sources: VXI TTL triggers, VXI Trigger commands, *TRG command, and IMMediate triggers. The TRIGger[:SEQuence][:IMMediate] command, however, overrides this command. It triggers the module and skips the delay specified in a previously issued TRIGger [:SEQuence]:DELay command. Initiate the scan sequence. Close the first relay in the sequence. Open the first relay and close the second relay in the sequence.

A module_name is an ASCII string that has been associated with a relay module in a [ROUTe:]MODule[:DEFine] command. A channel_range may consist of a single or a range of s. A range of s consists of two separated by a colon (:) character. One, two and three dimensional s are supported for the VX4380. A three dimensional consists of three ASCII-encoded decimal integers separated by exclamation point characters (!). The first integer specifies a row, the second a column, and the third a section of the VX4380. For example, 2!3!4 specifies the relay that joins row 2 to column 3 in section 4 of the VX4380. Two dimensional s consist of two ASCII-encoded decimal integers separated by an exclamation point character. The first integer specifies a row and the second specifies a column. When a two dimensional is issued, the section number defaults to 1.

For example, the channel spec 3!10!2 specifies the relay that connects row 3 to column 10 in section 2. The equivalent one dimensional is equal to ((2–1) × 64) + ((3–1) × 16) + 10 = 106. Description This command closes the relays specified in the portion of this command. After these relays are closed, a delay specified in a previously issued [ROUTe:]CLOSe:DWELl command is generated. This command is used to assign a close delay to each module controlled by an Option 01 daughter board. If more than one module is specified in the argument of the [ROUTe:]CLOSe command, the longest dwell time assigned to any of the specified modules is used. After this delay, VXI TTL triggers that have been enabled by a previously issued OUTPut:TTLTRG :STATE command are pulsed low for 3 sec. Examples In this example, the Option 01 is installed on a VX4380 Module. Two additional VX4380 Modules are installed in consecutive slots to the right of the first VX4380. The default module names for these three modules are m1, m2, and m3. These module names may be altered with the [ROUTe:]MODule[:DEFine] command.

When a trigger event is detected from an enabled trigger source, the next relay in an initiated scan sequence is closed after the current closed relay is opened. The action of opening the currently closed relay and closing the next relay in a scan list is called sequencing the scan list. Specifying BUS in the TRIGger[:SEQuence]:SOURce command enables a IEEE488.1 Group Execute Trigger command to sequence the scan list. It is assumed that the commander of the Option 01 is a IEEE488 talker/listener and that this device converts a IEEE488.1 GET command to a VXI Trigger command. Specifying HOLD in the TRIGger[:SEQuence]:SOURce command disables all trigger sources except the TRIGger[:SEQuence}[:IMMediate] comand. Specifying IMMediate in the TRIGger[:SEQuence]:SOURce command causes the Option 01 to sequence through the scan list without waiting for a trigger event. Specifying TTLTrg in the TRIGger[:SEQuence]:SOURce command enables one of eight VXI TTL triggers to act as a trigger source. is a single digit between 0 and 7.

VX4380 256-Crosspoint Relay Matrix Module User Manual IEEE-488.2 Common Commands This section lists the IEEE-488.2 common commands and queries recognized by the VX4380. *CLS Clear Status. This commands clears the following: Event Status register (ESR) Error/Event queue Output queue *ESE Event Status Enable (ESE) command. This command defines the mask for setting the Event Status Summary bit (bit 5) in the Status Byte register (*STB?). The mask is logically ANDed with the Event Status register (*ESR?) to determine whether or not to set the Event Status Summary bit. The mask can be any numeric value from 0 to 255, corresponding to the encoded bits of the ESR register. A “1” in a bit position enables reporting of the function. A “0” disables it. The *ESE register is cleared at power-on, or by writing an *ESE 0 command only. If is not specified, it defaults to 0. For example, the command *ESE 37 (hexadecimal 25, binary 00010101) enables setting the Event Status Summary bit whenever an operation is complete, a query error is detected, or an execution error is detected. *ESE? Event Status Enable (ESE) query. This command returns the value of the Event Status Enable register as a numeric value from 0 to 255. For example, a value of 32 (hexadecimal 40, binary 00100000) indicates that command error reporting is enabled. *ESR? Event Status Register (ESR) query. This command returns the value of the Event Status register. The *ESR command is destructively read (that is, read and cleared). The Event Status Summary bit in the Status Byte (*STB?) is also cleared by a read of the ESR. The ESR is set to 128 on power-on (bit 7) set. It is VX4380 256-Crosspoint Relay Matrix Module User Manual 3–53 IEEE-488.2 Common Commands cleared by an *ESR? or *CLS command only. When converted to a binary number, the bits of the ESR correspond to: bit 0 (LSB) 1 2 3 4 5 6 7 (MSB) Operation Complete Request Control Query error Device Dependent error Execution error Command error User Request Power On The Error bits are set whenever the module detects an error. The error values from –100 to –199 are Command errors. Error values from –200 to –299 are Execution errors. Error values from –300 to –399 are Device Dependent errors. Error values from –400 to –499 are Query errors (see the SYSTem:ERRor command description). The Request Control and User Request bits are unused, and are always reported as zeroes. The Operation Complete bit is set in response to an *OPC command. A 1 indicates that the module has completed all pending commands and queries. *IDN? Identification query; This returns a 4-field response. Field 1 is the manufacturer, field 2 the model, field 3 the serial number, and field 4 contains both the SCPI and the firmware version levels. For the VX4380, the serial number field is always a 0. The response syntax is: where xx indicates the model number of the relay module that the Option 01 is installed on: 3–54 Value of xx Model Number 20 VX4320 30 VX4330 50 VX4350 80 VX4380 VX4380 256-Crosspoint Relay Matrix Module User Manual IEEE-488.2 Common Commands *OPC Operation Complete. This command causes the module to set the Operation Complete bit in the Event Status register (ESR) when all pending commands and queries are complete. *OPC? Operation Complete query. This command causes the module to place a “1” in the Output queue when all pending commands and queries are complete. All commands following *OPC are suspended until the pending operations are complete. The *OPC? command does not affect the OPC bit in the Event Status register. *RST Reset. This command causes the Option 01 to open all relays on all modules under its control. This command sets the Option 01 Module to its power-on state with the following exceptions: the Error/Event queue, Output queue, Standard Event Status Enable register, SCPI Status Operation Event Enable register and SCPI Status Questionable Event Enable register are not cleared. The condition of the Option 01 daughter board and the switching modules that it controls after receipt of a *RST command is as follows: Contents of the SCPI Status Operation Event register = 0 Contents of the SCPI Status Operation Condition register = 0 Contents of the SCPI Status Questionable Event register = 0 Contents of the SCPI Status Questionable Condition register = 0 All VXI TTL triggers are disabled Trigger subsystem is in the idle state Trigger source = IMMediate Number of times to sequence through an entire scan list = 1 Time in seconds to wait after a trigger event is detected before sequencing to the Next relay in a scan list = 0 All relays on all modules are set to the open position No scan list is defined Default module names are assigned as follows: The module that has a Option 01 VXI Interface daughter board installed is assigned module name “M1”. Modules without the Option 01 VXI Interface daughter board in consecutive slots to the right of module “M1” are assigned module names “M2”, “M3”, ..., “M11”.

This command defines a mask that is ANDed with the contents of the Status Byte register. If the result of this operation is non-zero, the Option 01 generates a VXI Request True interrupt. Bits 0, 1, 3, 6, and 7 of the SRE register are not used. Bits 2, 4, and 5 are set to enable VXI Request True interrupts to be generated under the conditions listed in the following table. Bit No. Meaning bit0 (LSB) Not used 1 Not used 2 The Error/Event queue contains one or more error messages 3 Not used 4 The Output queue contains one or more query responses 5 The contents of the Standard Event Status register ANDed with the contents of the Standard Event Status Enable register produces a non-zero result. 6 Not used 7 Not used *SRE? Service Request Enable (SRE) query. This command returns the value of the Service Request Enable register as a numeric value from 0 to 255. Bit 6 is unused, and is reported as zero. 3–56 VX4380 256-Crosspoint Relay Matrix Module User Manual IEEE-488.2 Common Commands *STB? Status Byte Query. This query returns the value of the Status Byte register as a numeric value between 0 and 255. The Status Byte register contents (with the exception of bit 6) are also returned in response to a VXI Read STB command. Bit 6 is read destructively in response to a VXI Read STB command. Bit 6 is not read destructively is response to a *STB? query. The Status Byte register is encoded as follows: Bit No. Meaning bit 0 (lsb) Not used bit 1 Not used bit 2 Set when the Error/Event queue contains one or more error messages. bit 3 Not used bit 4 Set when the Output buffer contains one or more query responses. bit 5 Set when the contents of the Standard Event Status register ANDed with the contents of the Standard Event Status Enable register produces a non-zero result. bit 6 Set when the contents of bits 0 through 5 and bit 7 of the Status Byte register ANDed with the contents of the Service Request Enable register produce a non-zero result. If bit 6 becomes set, the Option 01 will generate a VXI Request True interrupt on the VME interrupt level selected by its interrupt level select switch. If bit 6 becomes set and the Status Byte register is read using a VXI Read STB command, bit 6 will be reported as being set. In response to subsequent VXI Read STB commands, bit 6 will be reported as being cleared. If bit 6 becomes set and the Status Byte register is read using a *STB? query, bit 6 will be reported as being set. Bit 6 will continue to be reported as set in reponse to *STB queries until the contents of bits 0 through 5 and bit 7 of the Status Byte register ANDed with the contents of the Service Request Enable register is equal to 0. bit 7 Not used. VX4380 256-Crosspoint Relay Matrix Module User Manual 3–57 IEEE-488.2 Common Commands *TRG Trigger Command. This command is equivalent to a VXI Trigger command. This command is valid only after the following commands have been received by the Option 01: Command Description [ROUTe:]SCAN Define a scan list TRIGger [:SEQuence] :SOURce BUS Select a VXI Trigger command as a trigger source. INITiate[:IMMediate] Initiate the scan list. This command places the trigger subsystem in the “ARM” state. The trigger subsystem remains in this state until the Option 01 has sequenced through the entire scan list “n” times, where “n” has been previously specified in a TRIGger[:SEQuence]:COUNT command. The trigger subsystem then returns to the IDLE state. The trigger subsystem also returns to the IDLE state if an ABORt command is received by the Option 01. After these commands have been issued, a *TRG command will cause the Option 01 to take the following actions: Generate a trigger delay that has previously been specified in a TRIGger [:SEQuence]:DELay command. Open the currently closed channel. Generate the open delay that has previously been specified in a [ROUTe:]OPEN:DWELl command. Close the next channel in the scan list. Generate the close delay that has previously been specified in a [ROUTe:]CLOSe:DWELl. Pulse one or more VXI TTL trigger signals that have been enabled by a previously issued OUTPut:TTLTRG [:STATe] ON command. If the module containing the channel is a scanner module, pulse the appropriate front panel encode signal. If another *TRG command is received before this sequence is complete, a SCPI –211,“Trigger ignored” error message will be placed in the Error/Event queue. The *TRG command will continue to have this effect until the trigger subsystem is placed in the IDLE state. If additional *TRG commands are recieved after the 3–58 VX4380 256-Crosspoint Relay Matrix Module User Manual IEEE-488.2 Common Commands trigger system is placed in the IDLE state, the Option 01 will place a SCPI –211,“Trigger Ignored” error message in the Error/Event queue. The IEEE-488.2 Specification equates the *TRG command with an IEEE-488.1 Group Execute Trigger (GET) command. IEEE-488-to-VXI interface modules typically convert IEEE-488.1 GET commands to VXI Trigger commands. For this reason, the Option 01 equates the *TRG command with a VXI Trigger command. *TST? Self Test query. In response to this query, the Option 01 performs a self test of each of the switching modules under its control. During self test, the Option 01 verifies that it can properly control the relay drive circuitry of each switching module under its control. After the self test is complete, each module is restored to its pretest state. If all modules pass self test, an ASCII “0” is placed in the Output buffer. If one or more modules fail the self test, an ASCII “1” is placed in the Output buffer and error message(s) describing the failure are queued in the Error/Event queue. Issue a SYSTem:ERRor? query to read these error messages. *WAI Wait to Continue. This command causes the module to wait until all pending commands and queries are complete. All commands following *WAI are suspended until the pending operations are complete. VX4380 256-Crosspoint Relay Matrix Module User Manual 3–59 IEEE-488.2 Common Commands 3–60 VX4380 256-Crosspoint Relay Matrix Module User Manual Status and Events Status and Events The Status and Event Reporting System reports asynchronous events and errors that occur in the VX4380 256-Crosspoint Relay Matrix Module. This system consists of four 8-bit registers and two queues that you access through the command language. You can use these registers and queues to query the instrument status and control the interrupts that report events. In general, after an interrupt occurs, first conduct a serial poll, query the registers to see why the interrupt occurred, and then send the SYSTem:ERRor? query to see a descriptive error message. This section describes the four registers and two queues of the Status and Event Reporting system. For each register, you are given a description, a table describing all of the bits, and an example of how to use the register. The Status and Event Reporting process, synchronizing programming commands, and the system messages are also described in this section. Status and Event Reporting System The Status and Event Reporting system monitors and reports such events as an error occurring or the availability of a response to a query. This system includes descriptions of the following registers and queues: Status Byte Register H Status Byte Register H Service Request Enable Register H Standard Event Status Register H Event Status Enable Register H Output queue H System Error and Event queue The Status Byte Register, shown in Table 4–1, summarizes information from other registers. Use a serial poll or a *STB? query to read the contents of the Status Byte Register. The response is the sum of the decimal values for all bits set. When you use a serial poll, bit 6 shows Request Service information. When you use the *STB? query, bit 6, the Master Status Summary bit, indicates that bits 5, 4, or 2 may be set. VX4380 256-Crosspoint Relay Matrix Module User Manual 4–1 Status and Events Table 4–1: The Status Byte Register Bit Decimal Value Function 0–1 – Not used. 2 4 Error/Event queue Not Empty indicates that information is contained in the Error/Event queue and is waiting to be read. 3 – Not used. 4 16 Message Available shows that output is available in the Output queue. 5 32 Event Status Bit indicates that one or more events have occurred and the corresponding bits in the Standard Event Status Register have been set. 6 64 Request Service (obtained from a serial poll) shows that the VX4380 has requested service from the GPIB controller. Master Status Summary (obtained from *STB? query) summarizes the Event Status bit, Message Available bits, and Error/Event queue Not Empty bits in the Status Byte Register. 7 – Not used. A common example of using the Status Byte register is to enable the Message Available bit. This is done by sending an *SRE 16 command to the Option 01 VXI Interface Module. If the *STB? query returns a value of 80, bit 4 (decimal value of 16) and bit 6 (decimal value of 64) have been set (giving a decimal sum of 80). Bit 4 indicates that a message is available in the output queue. Bit 6 indicates that a bit in the Status Byte register that has been enabled by setting the corresponding bit in the Service Request Enable register (in this case bit 4) has been set. Service Request Enable Register The Service Request Enable Register, shown in Table 4–2, controls which bits in the Status Byte Register will generate a service request. Use the *SRE command to set bits in the Service Request Enable Register. Use the *SRE? query to see which bits in this register are enabled. The response from this query is the sum of the decimal values for all bits set. Table 4–2: The Service Request Enable Register 4–2 Bit Decimal Value Function 0–1 – Not used 2 4 Error/Event queue Bit indicates that a service request will be generated when a message is placed in the Error/Event queue. VX4380 256-Crosspoint Relay Matrix Module User Manual Status and Events Table 4–2: The Service Request Enable Register (Cont.) Bit Decimal Value Function 3 8 Not used 4 16 Message Available Bit indicates that a service request will be generated when a message is placed in the Output queue. 5 32 Event Status Bit indicates that events summarized in bit 5 of the Status Byte Register will generate a service request. 6–7 – Not used If, for example, the *SRE? query returns a value of 48, bits 4 and 5 are set in the Service Request Enable Register. Any event that causes the Message Available bit (bit 4) or Event Status bit (bit 5) to be set in the Status Byte Register now generates an interrupt. If you want an interrupt to be generated only when the Event Status bit (bit 5) is set, use the *SRE 32 command. Standard Event Status Register The Standard Event Status Register, shown in Table 4–3, records many types of events that can occur in the VX4380. Use the *ESR? query to read the contents of this register. The response is the sum of the decimal values for all bits set. Reading this register clears all bits so the register can accumulate information about new events. Table 4–3: The Standard Event Status Register Bit Decimal Value 0 1 Operation Complete shows that the operation is complete. This bit is set when all pending operations complete following a *OPC command. 1 – Not used 2 4 Query Error shows that data in the Output queue was lost. 3 8 Not used 4 16 Execution Error shows that an error occurred while the VX4380 was executing a command or query. Table 4–6 on page 4–7 lists the execution error messages. 5 32 Command Error shows that an error occurred while the VX4380 was parsing a command or query. Table 4–5 on page 4–7 lists the command error messages. 6 – Not used 7 128 Power On shows that the VX4380 was powered on. Function VX4380 256-Crosspoint Relay Matrix Module User Manual 4–3 Status and Events The following example assumes that all bits have been enabled using the Event Status Enable Register (see the next section for information about this register). If a *ESR? query returns a value of 128, bit 7 (decimal value of 128) is set indicating that the instrument is in the initial power-on state. Event Status Enable Register The Event Status Enable Register, shown in Table 4–4, controls which events are summarized in the Event Status bit (bit 5) of the Status Byte Register. Use the *ESE command to set bits in the Event Status Enable Register. Use the *ESE? query to see what bits in the Event Status Enable Register are set. The response from this query is the sum of the decimal values for all bits summarized in the event status bit of the Status Byte Register. Table 4–4: The Event Status Enable Register Bit Decimal Value 0 1 Set bit 5 of the Status Byte register when bit 1 (the Operation Complete bit) of the Standard Event Status register is set. 1 2 Not used 2 4 Set bit 5 of the Status Byte register when bit 2 (the Query Error bit ) of the Standard Event Status register is set. 3 8 Not used 4 16 Set bit 5 of the Status Byte register when bit 4 (the Execution Error bit) of the Standard Event Status register is set. 5 32 Set bit 5 of the Status Byte register when bit 5 (the Command Error bit) of the Standard Event Status register is set. 6 64 Not used 7 128 Set bit 5 of the Status Byte register when bit 7 (the Power On bit) of the Standard Event Status register is set. Function If, for example, the *ESE? query returns a value of 255, all bits are set, indicating that all events will set the event status bit (bit 5) of the Status Byte Register. The Output Queue The System Error and Event Queue 4–4 The VX4380 stores query responses in the Output queue. The VX4380 error and event messages are stored in the System Error and Event queue. Use the SYSTem:ERRor? query to get the event number and a text description of the event. Reading an event removes it from the queue. The Event queue stores detailed information for up to 10 events; the events are stored in first-in first-out order.

If the corresponding bit in the Event Status Enable Register is also enabled (2), then the event status bit in the Status Byte Register is set to one (3). VX4380 256-Crosspoint Relay Matrix Module User Manual 4–5 Status and Events When output is sent to the Output queue (for example, a response to a query), the message available bit in the Status Byte Register is set to one (4). When a bit in the Status Byte Register is set to one and the corresponding bit in the Service Request Enable Register is enabled (5), the master status summary bit in the Status Byte Register is set to one and a service request is generated (6). Messages The VX4380 generates error messages in response to events caused by commands or queries. Each type of event sets a specific bit in the Standard Event Status Register. Thus, each message is associated with a specific Standard Event Status Register bit. In the message tables that follow, the associated Standard Event Status Register bit is specified in the table title. Not shown in the tables are secondary messages giving more detail about the cause of the error or the meaning of the message.

Note that this command causes all relays in the scan list to be opened. WRITE H scan (@matrix_2(1!1!3:1!16!3)) Set the trigger source for the defined scan list to “immediate”. This causes the Option 01 daughter board to generate its own internal triggers. Each time a trigger is generated, the following sequence of events occurs: Wait for the trigger delay defined by the TRIGger[:SEQuence]:DELay command to expire. Open the relay in the scan list that is currently closed. Wait for the open dwell time assigned to the module containing the relay just opened to expire. Close the next relay in the scan list. Wait for the close dwell time assigned to the module containing the relay just closed to expire. Pulse any enabled VXI TTL triggers low for 3 sec. In this case, the default trigger delay of 0 is used, the default open dwell time of 0 is used, and the close dwell time has been set to 0.25 seconds. Note that the second and third events are skipped when the first trigger is received. The last three events are skipped when the last trigger is received. Triggers are not recognized until an INITiate[:IMMediate] or an INITiate:Continuous command is received. H Set the number of times to scan through the defined scan list to 2, to begin when an INITiate[:IMMediat] command is received. WRITE H Scan through the entire scan list two times.

Although some of these terms may have different meanings in other systems, it is important to use these definitions in VXIbus applications. Terms which apply only to a particular instrument module are noted. Not all terms appear in every manual. Accessed Indicator An amber LED indicator that lights when the module identity is selected by the Resource Manager module, and flashes during any I/O operation for the module. ACFAIL* A VMEbus backplane line that is asserted under these conditions: 1) by the mainframe Power Supply when a power failure has occurred (either AC line source or power supply malfunction), or 2) by the front panel ON/ STANDBY switch when switched to STANDBY. Asynchronous Communication Communications that occur outside the normal “command-response” cycle. Such communications have higher priority than synchronous communication. Backplane The printed circuit board that is mounted in a VXIbus mainframe to provide the interface between VXIbus modules and between those modules and the external system. Bus Arbitration In the VMEbus interface, a system for resolving contention for service among VMEbus Master devices on the VMEbus. Bus Timer A functional module that measures the duration of each data transfer on the Data Transfer Bus (DTB) and terminates the DTB cycle if the duration is excessive. Without the termination capability of this module, a Bus Master attempt to transfer data to or from a non-existent Slave location could result in an infinitely long wait for the Slave response. Client In shared memory protocol (SMP), that half of an SMP channel that does not control the shared memory buffers. CLK10 A 10 MHz, ±100 ppm, individually buffered (to each module slot), differential ECL system clock that is sourced from Slot 0 and distributed to VX4380 256-Crosspoint Relay Matrix Module User Manual Glossary–1 Glossary Slots 1–12 on P2. It is distributed to each module slot as a single source, single destination signal with a matched delay of under 8 ns. Commander In the VXIbus interface, a device that controls another device (a servant). A commander may be a servant of another commander. Command A directive to a device. There are three types of commands: In Word Serial Protocol, a 16-bit imperative to a servant from its commander. In Shared Memory Protocol, a 16-bit imperative from a client to a server, or vice versa. In a Message, an ASCII-coded, multi-byte directive to any receiving device. Communication Registers In word serial protocol, a set of device registers that are accessible to the commander of the device. Such registers are used for inter-device communications, and are required on all VXIbus message-based devices. Configuration Registers A set of registers that allow the system to identify a (module) device type, model, manufacturer, address space, and memory requirements. In order to support automatic system and memory configuration, the VXIbus standard specifies that all VXIbus devices have a set of such registers, all accessible from P1 on the VMEbus. C-Size Card A VXIbus instrument module that is 340.0 mm × 233.4 mm × 30.48 mm (13.4 in. × 9.2 in × 1.2 in).

ECLTRG Six single-ended ECL trigger lines (two on P2 and four on P3) that function as inter-module timing resources, and that are bussed across the VXIbus subsystem backplane. Any module, including the Slot 0 module, may drive and receive information from these lines. These lines have an impedance of 50 W; the asserted state is logical High. Embedded Address An address in a communications protocol in which the destination of the message is included in the message. ESTST Extended STart/STop protocol; used to synchronize VXIbus modules. Extended Self Test Any self test or diagnostic power-on routine that executes after the initial kernel self test program. External System Controller The host computer or other external controller that exerts overall control over VXIbus operations. FAILED Indicator A red LED indicator that lights when a device on the VXIbus has detected an internal fault. This might result in the assertion of the SYSFAIL* line. IACK Daisy Chain Driver The circuit that drives the VMEbus Interrupt Acknowledge daisy chain line that runs continuously through all installed modules or through jumpers across the backplane. ID-ROM An NVRAM storage area that provides for non-volatile storage of diagnostic data. Instrument Module A plug-in printed circuit board, with associated components and shields, that VX4380 256-Crosspoint Relay Matrix Module User Manual Glossary–3 Glossary may be installed in a VXIbus mainframe. An instrument module may contain more than one device. Also, one device may require more than one instrument module. Interface Device A VXIbus device that provides one or more interfaces to external equipment. Interrupt Handler A functional module that detects interrupt requests generated by Interrupters and responds to those requests by requesting status and identity information. Interrupter A device capable of asserting VMEbus interrupts and performing the interrupt acknowledge sequence. IRQ The Interrupt ReQuest signal, which is the VMEbus interrupt line that is asserted by an Interrupter to signify to the controller that a device on the bus requires service by the controller. Local Bus A daisy-chained bus that connects adjacent VXIbus slots. Local Controller The instrument module that performs system control and external interface functions for the instrument modules in a VXIbus mainframe or several mainframes. See Resource Manager. Local Processor The processor on an instrument module. Logical Address The smallest functional unit recognized by a VXIbus system. It is often used to identify a particular module. Mainframe Card Cage. For example, the Tektronix VX1410 Intelliframe, an operable housing that includes 13 C-size VXIbus instrument module slots. Memory Device A storage element (such as bubble memory, RAM, and ROM) that has configuration registers and memory attributes (such as type and access time). Message A series of data bytes that are treated as a single communication, with a well defined terminator and message body. Message Based Device A VXIbus device that supports VXI configuration and communication registers. Such devices support the word serial protocol, and possibly other message-based protocols. Glossary–4 VX4380 256-Crosspoint Relay Matrix Module User Manual Glossary MODID Lines Module/system identity lines. Physical Address The address assigned to a backplane slot during an access. Power Monitor A device that monitors backplane power and reports fault conditions. P1 The top-most backplane connector for a given module slot in a vertical mainframe. The left-most backplane connector for a given slot in a horizontal mainframe. P2 The bottom backplane connector for a given module slot in a vertical C-size mainframe; or the middle backplane connector for a given module slot in a vertical D-size mainframe such as the VX1500. Query A form of command that allows for inquiry to obtain status or data. READY Indicator A green LED indicator that lights when the power-on diagnostic routines have been completed successfully. An internal failure or failure of +5 V power will extinguish this indicator. Register Based Device A VXIbus device that supports VXI register maps, but not high level VXIbus communication protocols; includes devices that are register-based servant elements. Requester A functional module that resides on the same module as a Master or Interrupt Handler and requests use of the DTB whenever its Master or Interrupt Handler requires it. Resource Manager A VXIbus device that provides configuration management services such as address map configuration, determining system hierarchy, allocating shared system resources, performing system self test diagnostics, and initializing system commanders. Self Calibration A routine that verifies the basic calibration of the instrument module circuits, and adjusts this calibration to compensate for short- and long-term variables. Self Test A set of routines that determine if the instrument module circuits will VX4380 256-Crosspoint Relay Matrix Module User Manual Glossary–5 Glossary perform according to a given set of standards. A self test routine is performed upon power-on. Servant A VXIbus message-based device that is controlled by a commander. Server A shared memory device that controls the shared memory buffers used in a given Shared Memory Protocol channel. Shared Memory Protocol A communications protocol that uses a block of memory that is accessible to both client and server. The memory block operates as a message buffer for communications. Slot 0 Controller See Slot 0 Module. Also see Resource Manager. Slot 0 Module A VXIbus device that provides the minimum VXIbus slot 0 services to slots 1 through 12 (CLK10 and the module identity lines), but that may provide other services such as CLK100, SYNC100, STARBUS, and trigger control. SMP See Shared Memory Protocol. STARX Two (2) bi-directional, 50 W, differential ECL lines that provide for inter-module asynchronous communication. These pairs of timed and matched delay lines connect slot 0 and each of slots 1 through 12 in a mainframe. The delay between slots is less than 5 ns, and the lines are well matched for timing skew. STARY Two (2) bi-directional, 50 W, differential ECL lines that provide for inter-module asynchronous communication. These pairs of timed and matched delay lines connect slot 0 and each of slots 1 through 12 in a mainframe. The delay between slots is less than 5 ns, and the lines are well matched for timing skew. STST STart/STop protocol; used to synchronize modules. SYNC100 A Slot 0 signal that is used to synchronize multiple devices with respect to a given rising edge of CLK100. These signals are individually buffered and matched to less than 2 ns of skew. Synchronous Communications A communications system that follows the “command-response” cycle Glossary–6 VX4380 256-Crosspoint Relay Matrix Module User Manual Glossary model. In this model, a device issues a command to another device; the second device executes the command; then returns a response. Synchronous commands are executed in the order received. SYSFAIL* A signal line on the VMEbus that is used to indicate a failure by a device. The device that fails asserts this line. System Clock Driver A functional module that provides a 16 MHz timing signal on the Utility Bus. System Hierarchy The tree structure of the commander/servant relationships of all devices in the system at a given time. In the VXIbus structure, each servant has a commander. A commander may also have a commander.
