Note Setting the VXIbus Interrupt Level: The HP E1422 uses a default VXIbus

interrupt level of 1. The default setting is made at power-on and after a *RST command. You can change the interrupt level by executing the DIAGnostic:INTerrupt[:LINe] command in your application program.

Setting the Logical

Address Switch

Follow the next figure and ignore any switch numbering printed on the Logical Address switch. W hen installing more than one HP E1422 in a single VXIbus Mainframe, set each instrument to a different Logical Address.

Disabling the

Input Protect

Feature

(optional)

Disabling the Input Protect feature voids the HP E1422’s warranty. The Input Protect feature allows the HP E1422 to open all channel input relays if any input’s voltage exceeds ±19 volts (±6 volts for digital I/O SCPs). This fe ature will help to protect the card’s Signal Conditioning Plug-ons, input multiplexer, ranging amplifier, and A/D from destructive voltage le vels. The le vel that trips the protection function has been set to provide a high probability of protection. The voltage level that is certain to cause damage is somewhat higher. If in your

application the importance of completing a measurement run outweighs the added risk of damage to your HP E1422, you may choose to disable the Input Protect feature.

Voids Waranty! Disabling the Input Protection Feature voids the HP E1422’s warranty.

To disable the Input Prote ction feature, locat e and cut JM2202. Make a singl e cut in the jumper and bend the adjace nt ends ap art. Se e foll owing i llust ration for locat ion of JM2202.

Disabling

Flash Memory

Access

(optional)

The Flash Memory Protect Jumper (JM2201) is shipped in the “PROG” position. We recommend that you leave the jumper in this position so that all of the calibration commands can function. Changing the jumper to the protect position will mean you won't be able to execute:

•The SCPI calibration command CAL:STORE ADC | TARE

•The register-based calibration commands STORECAL, and STORETAR

•Any application that installs firmware-updates or makes any other

modification to Flash Memory through the A24 window.

With the jumper in the “PROG” po sition, you ca n completely ca librate one or mor e HP E1422s without removing them from the application system. An HP E1422 calibrated in its working environment will in general be better calibrated than if it were calibrated separate from its application system.

The multimeter you use dur ing the per i odi c ca li bra ti on c ycl e should be considered your calibration transfer standard. Have your Calibration Organization control unauthorized access to its calib ration cons tants. See the HP E1422 Service Manual for complete information on HP E1422 periodic calibration.

If you must limit access to the HP E1422's calibration constants, you can place JM2201 in the protected position and cover the shield retaining screws with calibration stickers. See following illustration for location of JM2201.

Installing the Module

Installation of the HP E1422 VXI module is covered in your HP Mainframe manual.

WARNING All instruments within the VXI mainframe are gr ounded thro ugh

the mainframe chassis. During insta llation, tighten the instrument’ s retaining screws to secure the instrument to the mainframe and to make the ground connection.

WARNING SHOCK HAZARD. Only qualified, service-trained personnel who

are aware of the hazards involved should install, configure, or remove the VXI Module. Disconnect all power sources from the mainframe, the Terminal Modules, and installed modules before installing or removing a module.

Instrument Drivers

Two driver types are supplied on the HP Universal Drivers CD that comes with your Instrument. There is a VXIpl ug&pl ay driver which includes a front panel program and help file. In addition there is also a down-loadable driver for the HP E1406A Command Module. Follow the instructions that are presented by the CD setup program. Also view the readme .txt file pro vided wit h the VXIplug&pl ay driver for possible update information.

About Example Programs

Examples on CD All example programs mentioned by file name in this manual are available on the

HP Universal Drivers CD supplied with your HP E1422. Again see the readme.txt file for the specific file locations of these examples.

Sequences

Typical Example

program

Where programming concept s ar e discussed in this manual, the commands to send to the HP E1422 are shown in the form of command sequences. These are not example programs because t hey are not written in a ny computer language. Th ey are meant to show the HP E1422 SCPI commands in th e sequ ence the y shoul d be se nt. Where necessary th ese sequences include comments to describ e program flow and

control such as loop - end loop, and if - end if. See “Example SCPI Command Sequence” on page 134. for an example. For VXIplug&play users, there is an “Example VXIplug&play Driver Function Sequence” on page 135.

The Verify program (file name ve rif.cpp) is printed below to show a typical VXIplug&play program for the HP E1422.

Verifying a Successful Configuration

An example ’C’ progra m source is s hown on th e fol lowing p ages. T his pr ogram is included on your HP Universal Drivers CD that comes with your HP E1422A (file name verif.cpp). The program uses the *IDN? query command to verify the HP E1422 is operational and r esponding t o commands. The program also has an error checking function ( check( )). It is important to include an instrument error checking routine in your programs, particularly your first trial programs so you get instant feedback while you are learning about the HP E1422. Compile this program according to the plug&play help file (hpe1422.hlp) topics "Introduction to Programming" Environments".

/******************************************************************************* verif.cpp

This example program verifies your instrument installation by reading the instrument IDs and then querying for and printing the SCP types found.

Use the "Copy Button" in the Help File’s "Example" window to place this code into the clipboard, then paste this code text into your development tool’s editor window. Similarly, "Copy" the actual example code from the help file’s "Example" window and paste it into the location provided below.
