3. Mounting and Connecting SLICE Hardware

This section gives details on how to connect your SLICE hardware. Choose the connection
method you have from the options below for the quickest information.

3.1. General Connection Guidelines

Great care should always be taken when connecting any power, switch, sensor or any
other device to the SLICE system.

! DO NOT exceed the rated voltage input range for the device. Whenever

possible use the power supply or battery pack supplied with your SLICE system.

Version 1.0 - May 2010 16 ©DTS, Inc. - All Rights Reserved

SLICE User’s Manual [e-mail]

! DO NOT connect directly to vehicle power or other noisy power sources.

! ALWAYS disconnect the battery from the SLICE system before connecting to a

battery charger.

! ALWAYS use SLICE NANO with a heat sink as the SLICE NANO case is very thin

aluminum with very little heat sinking ability. Never use SLICE NANO mounted
to a thermally non-conductive surface like wood or plastic.

! Refer to proper grounding procedures described in Appendix H.

! Check that all cables show no signs of physical damage.

! Be sure all sensors have their cable shields ungrounded at the sensor end and

grounded at the SLICE input connector.

3.2. Guidelines for High Shock and Vibration Testing

SLICE MICRO and SLICE NANO components can generally be used in test environ­ments with maximum acceleration levels as high as 500 g. In some cases, SLICE
NANO can be used up to 5,000 g if proper care is used.

Proper mounting of the SLICE system, cables, and accessories is critical to successful
testing.

! DO NOT mount SLICE components in an area where they may be directly

impacted by an object.

! Use damping material whenever possible to help protect the SLICE system

from excessive shock or vibration, but remember that SLICE NANO requires a
heat sink.

! Be sure that connectors and wiring are properly secured.

3.3. SLICE Connectors and Cables

3.3.1. SLICE Connectors

SLICE is an ultra small data acquisition system. One challenge with a small
system is electrical connections. Although connectors such as Bendix, Amphenol,
and LEMO are common for instrumentation, all of these are much too large to be
practical for SLICE.

The SLICE system uses circular plastic connectors manufactured by Omnetics
Corporation (www.omnetics.com
contacts and are used in many military, aerospace and other high shock applica­tions. Connectors are available direct from Omnetics or can be purchased from
DTS.

Below are the connector types used by SLICE.

). These connectors use high-quality, machined

3.3.2. SLICE Cables

DTS provides a number of different SLICE cable options depending on the
connection needs. SLICE stack to stack connection cables are shown below.

SLICE MICRO Base units can be connected together via a daisy-chain cable.
SLICE NANO Base units can be connected to each other directly or via a daisy­chain extension cable.

! The AUX connector is a standard D-sub HD15. This can be used to hardwire a

Start Record or Event switch or monitor the Status line.

3.8. Using the SLICE Ethernet Interface

The SLICE Ethernet Interface is similar to the SLICE USB Interface. The main
difference is that the SLICE Ethernet Interface has an Ethernet connection to the PC
instead of a USB connection. This allows for a longer communications cable between
the PC and the SLICE system. The SLICE Ethernet Interface can also connect 2 SLICE
chains for large system configurations. See the example diagram below.

Notes:

! Although this shows a SLICE MICRO, connections with a SLICE NANO are

similar.

! The AUX connector is a standard D-sub HD15. This can be used to hardwire a

Start Record or Event switch or monitor the Status line.

3.9. Using the SLICE Distributor

The SLICE Distributor allows for the connection of up to 4 SLICE chains and converts
the communications signals from USB to Ethernet. This allows for a longer communi­cations cable between the PC and the SLICE system. The most common application
for the SLICE Distributor is for an embedded system with a high channel count as
shown for the in-dummy (manikin) configuration below.

4. Sensor ID and Supported Sensor Types

This section covers basic information regarding SLICE compatible sensors and sensor ID.
More detailed information regarding sensor connections can be found in Appendix I.

The diagram below shows a common 4-wire bridge sensor connection to a Bridge SLICE
input channel.

4.1. Sensor ID

Sensor ID is also referred to as electronic ID (EID). The function of EID is for the
SLICE hardware to automatically read and determine what sensor is attached to each
sensor input channel.

SLICE uses EID chips from Maxim IC, model DS2401 (see http://www.maxim-

ic.com/quick_view2.cfm/qv_pk/2903). To make soldering of the EID more easy, DTS

provides EID microcards, which have a chip scale packaged DS2401 soldered to a
circuit board with wires attached (see below).

Omnetics 7-pin Sensor Connector

4.2. Supported Sensor Types

The Bridge SLICE supplies 5 VDC excitation up to 20 mA and supports many types of
accelerometers, load cells, pressure sensors and other sensor types. The following
general sensor types are supported:

! Full (4-wire) or half bridge (2- or 3-wire) resistive and piezo-resistive types
! Voltage input: Input range 0.1 to 4.9 V; larger range with voltage expander

circuit

! Conditioned sensors with 5 V excitation and 2.5 V centered signal output

The IEPE SLICE MICRO (fourth quarter 2010) will support common piezo-electric

5.2. Data Collection Concepts

This section discusses the basics of data collection with SLICE.

5.2.1. Standalone Operation

SLICE is a standalone data logger. This means that once it is armed, the PC can
be disconnected if desired. After receiving a Start Record or Trigger signal, the
SLICE autonomously collects data, storing it to flash memory with no user
interaction. After the test, the user can reconnect the PC to download the data.

There is also a real-time mode in the SLICEWare software application that
allows the user to check channel inputs on an oscillograph-looking screen.

5.2.2. Data Collection Modes

SLICE supports two data collection modes, Circular Buffer and Recorder.

5.2.2.1. Circular Buffer Mode

In circular buffer mode, the user can program SLICE to record pre-trigger
data. For example, the test set-up can specify to record x seconds pre­trigger and x seconds post trigger. Time Zero (T=0) is marked when the
trigger signal is received.

5.2.2.2. Recorder Mode

5.3. SLICEWare

This section discusses the basics of data collection with SLICE using the SLICEWare
application.

The SLICEWare software application allows for easy:

! Test set-up
! Sensor database management
! Real-time sensor check-out
! Test execution
! Data download and viewing
! Data export

Recorder mode starts when a Start Record signal is received and continues
for the time specified in the test set-up. If a trigger signal is received
sometime after the Start Record, this marks the T=0 point.

sensor.

! Un-assign: Remove the highlighted channel in the Connected Sensors area.

! Apply: Commits the sensor set-up information to SLICE.

! Note: A sensor that is manually applied should not have a value in the

Sensor ID field and the SLICE should not have an EID installed on the
connector. If the Sensor ID field is populated or an EID exists on the
channel, the sensor will need to be re-applied after switching away from

Calibration History

! This field is automatically updated whenever a new sensitivity is applied to

the sensor attributes. You cannot enter directly into this field.

Options

! Invert: When checked, the data will be inverted.

! Shunt Check and Bridge Resistance: When Shunt Check is checked, the

sensor will have the bridge resistance measured during diagnostics and
compared to the value entered in Bridge resistance.

! SW Filter: Choose the frequency of a software filter to be applied to the

data when viewing. This only affects the viewed data as all data stored will
be as collected with the hardware anti-alias filter.

! Zero Method (post download software zeroing):

o Use Pre-Cal Zero: The Zero Measured Output (ZMO) of the sensor

during calibration will be used to set the EU zero of the downloaded
data.

o Average Over Time: Used in conjunction with ZeroStart and

ZeroEnd, the average EU value during the Start and End window
will be used to Zero the collected data. The Zero Start/End window
must be set to data that will be collected. If using a negative time,
then the Acquire tab must include this window.

o None: The actual recorded input will not be adjusted or

compensated for zero level. This setting can be used to show the
actual mV offset. An example may be to record a logic level signal
and see the actual on/off state.

o Remove Offset (hardware): When checked, this will remove the

ZMO during diagnostics. This will “electrically” zero the input.

o ZeroStart/End: See Zero Method!Average Over Time.
o Offset Check: Used in conjunction with Limit Low/High during

diagnostics. When checked, the ZMO is measured and compared
the Low/High limits as a pass/fail criteria during diagnostics.

SL ICE Grounding and Shielding Overvie

w

Electromagnetic Interference (EMI), Radio Frequency Interference (RFI) and
Electrostatic Discharge (ESD) can seriously degrade the performance of

electronic equipment if not addressed. DTS SLICE systems contain protection

f

or

EMI/RFI/ESD, h

owever, many dynamic testing environments

(pyrotechnics, blast) are particularly noisy and require the utmost attention
to grounding and shielding practices. The following recomm endations are
intended to maximize protection and keep systems functioning properly in

the harshest environments

.

Ground all DAS equipment, power supplies and sensor mounting fixtures
whenever possible. This is an extremely important s tep toward ensuring the

best performance from your SLICE system.

•Always connect a cable from a good Earth ground to the test article, test fixture or

instrumented vehicle. Not only does this help divert potentially disruptive electrical
energy, it is also good safety practice. For remote testing applications, a metal ground
rod driven 3 ft into the soil can be an effective Earthing device.

•Ground

all SLICE enclosures to the test article o

r v

ehicle

• Install ground cables between all SLICE Stacks and the test article or vehicle.

• Install ground cables between electrically isolated test article/sensor mounting surfaces

and the SLICE Stacks.

© 2009-2010 DTS Principles of Dynamic Data Acquisition

SL ICE Grounding and Shielding Overvie

w

Shield sensor cables

• Use shielded sensor cables. The shield provides a path for EMI /RFI energy to flow to the

DAS ground and enclosure, thus reducing effects on sensor signals.

“

”

•

Connect the sensor cable shield on the DAS side only to the Shield or ground pin on the

SLICE.

• Do not connect the shield at both ends. Connecting the sensor cable shield at both ends

will cause large ground-loop currents that can increase noise or cause damage.

• P C Grounding?

g

• This is more important than you might think.

• If the Laptop used to communicate with SLICE is powered from a source that has a

significantly different ground potential than the SLICE system, communication with the
SLICE can be impaired. In severe cases damage to the laptop or SLICE can occur .

• Either run the la

ptop

on battery power or use a voltmeter to make sure the AC outlet

p p y p

g

round is not at a significantly different potential than the ground connected to the test

article or vehicle.

• Carefully consider routing and cable design for any high current signals to air bags,

cameras, lights, etc.

•

Route these cables away from sensor wiring

.

• Cross sensor wiring at 90" angles if the cables must cross.

ommendations

• Flat braided ground cable has lower impedance than typical round

wires and hence makes a better ground connection.

• Never assume that co nnections are good until you check them with

an ohmmeter. Should be <1# for short runs or <5# for long runs.

• Ground cables inside test dummies should be braided type with a 12-

gage equivalent size.

• Ground cables from a test article or vehicle to the SLICE Stack should

be braided strap type with a 15-gage equivalent size.

• The cable from a test article or vehicle to the Earth connection

should be large enough to create an a low impedance connection
given the distance between Earth connection and test vehicle. 8 to
12 gage equivalent is comm o n.

• If braided cable is not available, any ground wire is better than none!

Overview

The .DTS file is an XML based file that contains information about the overall test and the individual
channels. Some of the information may be redundant with information stored in the binary channel header.

The attributes and relationships of each XML node are described below

XML Structure

<Test>

The Test tag is the outer most tag. It's attributes describe details common to the entire test. It contains the
following attributes.

Name Data type Description

Id String

The name of the test, typically the same as the .DTS
file name

Description String The description of the test provided by the user.

InlineSerializedData Boolean

Guid Windows UUID string A unique identifier assigned to each event

<Modules>

Within the Test node will be a list of modules contained within a <Modules></Modules> tag. A module
corresponds to a data acquisition system - for example an entire stack. Each module will have it's own
<Module> tag with the following attributes.

Name

Data

type

Description

AaFilterRateHz Integer

Appendix J: Software Information

XML Structure

The name cut off frequency of the hardware anti-alias filter
used during the test

Number Integer A sequential number assigned to each module within the test

SerialNumber String The factory assigned serial number of the base

NumberOfSamples Integer

The number of samples stored in each channel file. This will be
fewer than the number of samples originally requested by the
user if the data has been sub sampled or if only a portion of the
data was downloaded.

UnsubsampledNumberOfSamples Integer The total number of samples collected during data acquisition

PostTriggerSeconds Double

The number of seconds of recorded data that the user requested
after t=0.

PreTriggerSeconds Double

The number of seconds of recorded data that the user requested
before t=0.

RecordingMode String

Either the value RecorderMode or CircularBuffer. Other values
will be added in the future.

SampleRateHz Integer The rate at which sampling occurred during data collection.

StartRecordSampleNumber Integer

The sample number at which the start signal was first detected.
The value will always be 0 when
RecordingMode=CircularBuffer

NumberOfChannels Integer The number of user configured channels within the module

InlineSerializedData Boolean

<TriggerSampleNumbers>

This is a list (possibly 0 length) of trigger sample numbers. In the circular buffer case there will be one trigger
sample number. In recorder mode the trigger is optional. In the case of multiple event mode, there may be
more than one trigger sample number.

<Channels>

The Channels tag contains a list of channel elements. It should have the same number of entries as
NumberOfChannels in the Module tag. The type of the child elements will depend on the type of signal
conditioning SLICE used.

<AnalogInputChanel>

The AnalogInputChanel tag corresponds to a Bridge SLICE channel.

Note:

There is a typo in the tag name. Channel is misspelled. It is left for backwards compatibility.

Many of the attributes indicate how the channel was configured during the test. The AnalogInputChanel
element has the following properties:

Name Data type Description

ChannelType String This identifies the representation of the data contained in

the .BIN file. Currently this value is always expected to be

SLICEWare_DTS_File_Format

<Modules>

DTS.Serialization.Test+Module+AnalogInputChannel

Number Integer

The channel number within the signal conditioning unit. In
a Bridge SLICE channels are numbered 0 - 2

Start Date Currently unused

Bridge String Either FullBridge or HalfBridge

BridgeResistanceOhms Integer

The specified bridge resistance used during the shunt
check.

ChannelDescriptionString String The user provided description for the channel

Description String

The user provided description for the sensor. Currently the
same as ChannelDescriptionString

Sensitivity Double

The sensitivity of the sensor in either mv/V/EU or mv/EU
depending on ProportionalToExcitation

SoftwareFilter String

The requested filtering to apply to this channel. Stored data
is unfiltered, and this value must be used to apply proper
filtering. Typical values are "1650hz" for CFC1000.

ProportionalToExcitation Boolean

Indicates if the output of this sensor is proportional to
excitation. Used in conjunction with Sensitivity.

IsInverted Boolean

(Optional)

Indicates if the data should be inverted before
presenting to the user. If missing, this attribute is
considered 'false'.

IsSubsampled Boolean

(Optional) Indicates if the data stored on disk is at a lower
sample rate than the original data collection. If missing,
this attribute is considered 'false'.

ExcitationVoltage String

Indicates the nominal excitation voltage. Valid values are
currently Volt5 and Volt2.5.

Eu String

The user provided Engineering Units (EU). For example
"mm", "g", or "msec2"

SerialNumber String The serial number of the sensor used with this channel

ShuntEnabled Boolean

Indicates if the user requested the channel be shunted
during diagnostics.

RemoveOffset Boolean

Indicates if the user requested hardware offset
compensation be used during diagnostics.

ZeroMethod String

Identifies the type of software offset compensation that
should be used. If the value is "UsePreCalZero" then the
Pre Calibration zero value stored in the channel file should
be used. If the value is "AverageOverTime" then an
average value computed from the channel data should be
used.

ZeroAverageWindowBegin Double

If ZeroMethod=AverageOverTime this is the beginning of
the window to be used for computing the average.

ZeroAverageWindowEnd Double

If ZeroMethod=AverageOverTime this is the end of the
window to be used for computing the average.

InitialEu Double

A value provided by the user that should be subtracted
from all scaled data in addition to the selected ZeroMethod

UnsubsampledSampleRateHz Integer

The sampling rate used during data collection. Valid only if
IsSubsampled=true

SLICEWare_DTS_File_Format

<AnalogInputChanel>

MeasuredShuntDeflectionMv Double

(Optional)

If a shunt test was performed, the actual
deflection of the shunt

TargetShuntDeflectionMv Double

(Optional) If a shunt test was performed, the expected
shunt deflection

MeasuredExcitationVoltage Double

(Optional) The measured excitation voltage, if available.
Used by SliceWARE for scaling proportional-to-excitation
sensor data if "factory" excitation voltage is not available.

FactoryExcitationVoltage Double

(Optional) The factory excitation voltage, if available.
Used by SliceWARE for scaling proportional-to-excitation
sensor data.
