About this Chapter
This chapter will explain hardware configuration before installation in a
VXIbus mainframe. By attending to each of these configuration items, your
HP E1419A won’t have to be removed from its mainframe later. Chapter
contents include:

Configuring the HP E1419A
There are several aspects to configuring the module before installing it in a
VXIbus mainframe. They are:
•Setting the Logical Address Switch . . . . . . . . . . . . . . . . . . . 14
•Installing Signal Conditioning Plug-ons . . . . . . . . . . . . . . . . 15
•Disabling the Input Protect Feature . . . . . . . . . . . . . . . . . . . 19
•Disabling Flash Memory Access . . . . . . . . . . . . . . . . . . . . . 19
For most applications you will only need to change the Logical Address
switch and install SCPs prior to installation in a mainframe. The other
settings can be used as delivered.
Switch/Jumper Setting
Logical Address Switch 208
Input Protect Jumper Protected
Flash Memory Protect Jumper PROG
NOTE Setting the VXIbus Interrupt Level: The HP E1419A uses a default VXIbus
interrupt level of 1. The default setting is in effect 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.
Chapter 1 Getting Started 13

Setting the Logical
Address Switch Follow the next figure and ignore any switch numbering printed on the
Logical Address switch. When installing more than one HP E1419A in a
single VXIbus Mainframe, set each instrument to a different Logical
Address.

Installing Signal
Conditioning
Plug-ons
The following illustrations show the steps you’ll use to install Signal
Conditioning Plug-ons. The HP E1419A supports only non-programmable
analog input SCPs in positions 0 through 3. Any mix of SCP types can be
installed in SCP positions 4 through 7.
CAUTION Use approved Static Discharge Safe handling procedures anytime you have
the covers removed from the HP E1419A or are handling SCPs.

Disabling the Input
Protect Feature
(optional)
Disabling the Input Protect feature voids the HP E1419A’s warranty. The
Input Protect feature allows the HP E1419A to open all channel input relays
if any input’s voltage exceeds ±19 volts (±6 volts for non-isolated digital
I/O SCPs). This feature will help to protect the card’s Signal Conditioning
Plug-ons, input multiplexer, ranging amplifier, and A/D from destructive
voltage levels. The level 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 E1419A, you may choose to disable the Input Protect
feature.
VOIDS WARRANTY Disabling the Input Protection Feature voids the HP E1419A’s warranty.
To disable the Input Protection feature, locate and cut JM2202. Make a
single cut in the jumper and bend the adjacent ends apart. See following
illustration for location 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” position, you can completely calibrate one
or more HP E1419As without removing them from the application system.
An HP E1419A 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 during the periodic calibration cycle should be
considered your calibration transfer standard. Have your Calibration
Organization control unauthorized access to its calibration constants. See the
HP E1419A Service Manual for complete information on HP E1419A
periodic calibration.
If you must limit access to the HP E1419A’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.
