applications. Each VIBbox packages up to four DT9857E
modules in a rugged enclosure to provide up to 64 IEPE
24-bit Delta-Sigma sensor inputs, 8 D/A stimulus outputs,
4 tachometers, 4 32-bit counter/timers, 8 measurecounters, and 32 DIO lines. If additional channels arerequired, users can connect multiple VIBboxes together
to achieve up to 256 IEPE inputs, 32 D/A stimulus
outputs, 16 tachometers, 16 32-bit counter/timers, 32

VIBbox-64 provides 64 analog IEPE input channels,VIBbox-48 provides 48 IEPE inputs, and VIBbox-32
provides 32 IEPE inputs. Software-selectable gains of 1
and 10 provide effective input ranges of ±10 V and ±1V. Each analog input channel uses a 24-bit Delta-Sigma

IEPE Support

Analog Output ClockApplications that require accelerometer, vibration, noise,or sonar measurements often use IEPE sensors. IEPE
conditioning is built-in to the analog input circuitry of theVIBbox. Each analog input channel provides the following
capabilities for IEPE support:

VIBbox supports an internal D/A clock, which is derived
from the 48 MHz crystal oscillator. The clock frequencyof the D/A output clock can be programmed to avalue between 30 kHz and 216 kHz for pacing output
operations.

• Excitation current source — Internal excitation

Output Triggers

current source of 4 mA.
• Coupling type — Software-programmable AC
coupling or DC coupling.
• Compliance voltage — +24 V

To start an output operation, the following output
triggers are supported: software trigger or external
digital (TTL) positive or negative trigger.

Analog Input Clock

Tachometer Inputs

VIBbox supports an internal clock, which is derived fromthe 48 MHz crystal oscillator, for pacing analog input
operations. The sampling frequency can be programmed
to a value between 195.3 Hz and 105.4 kHz.

VIBbox-64 supports four tachometer input signals,
VIBbox-48 supports three tachometers, and VIBbox-32
supports two tachometers, all with a range of ±30 V.
The frequency or period between two edges of thetachometer input signal can be measured to calculate
the rotational speed of the high level tachometer input.
The values can then be returned in the analog input data
stream. The starting edge (either rising or falling) of eachtachometer signal is programmable. An internal 12 MHz
counter is used for the measurement.

Input Triggers
VIBbox supports both a start trigger and a reference
trigger. Users can specify a start trigger to acquirepost-trigger data when the specified start trigger event
occurs. To acquire pre- and post-trigger data, users canspecify both a start trigger and a reference trigger. In
this case, pre-trigger data is acquired when the start
trigger occurs and post-trigger data is acquired when thereference trigger occurs. Post-trigger acquisition stops
when a user-specified number of samples have beenacquired. The following trigger sources are supported:

General-Purpose Counter/Timers
VIBbox-64 supports four 32-bit, general-purpose
counter/timers, VIBbox-48 supports three counter/timers, and VIBbox-32 supports two counter/timers.
The value of the counter/timers can be returned in
the analog input data stream, if desired. The following
counter/timer functions are supported: event counting,edge-to-edge measurement, continuous edge-to-edge
measurement (for determining the frequency and period
width of a signal), continuous pulse output, one-shot,repetitive one-shot, and up/down counting operations.
Programmable gates, clocks, and output signals are alsosupported.

• software trigger source (start trigger only)• external digital (TTL) positive or negative trigger• threshold trigger
Analog Output Channels
VIBbox-64 supports eight 32-bit analog output channels,
VIBbox-48 supports six analog outputs, and VIBbox-32
supports four analog outputs, all with an output rangeof ±10 V. A two-pole Butterworth filter and quiet start
circuitry prevents noise from interfering with the output
signal. VIBbox supports single-value, waveform, andcontinuous analog output operations. In addition, thedigital output ports can be updated simultaneously withthe analog output channels for simultaneous stimulus
and control applications.

Measure Counters

Digital I/O Lines

VIBbox-64 supports eight measure counters, VIBbox-48
supports six measure counters, and VIBbox-32 supports
four measure counters. Each counter can measure thefrequency or period between two signals or two edges ofthe same signal and return the value in the analog input
data stream. This is useful for correlating analog input
and digital positional data.

VIBbox-64 supports four digital input ports and four
digital output ports, the VIBbox-48 supports three digital
inputs ports and three digital output ports, and the
VIBbox-32 supports two of each.
Each digital input port consists of 8 digital input lines andeach digital output port consists of 8 digital output lines.
Users can read all digital input lines or write to all digital
output lines with a single-value digital I/O operation.

A variety of programmable signals and edges aresupported for the measurement, including the A/D
conversion complete, tachometer signal, measurecounter/timer, and digital input signals. An internal
48 MHz counter is used for the measurement.

Users can also return the value of the digital input
ports in the analog input stream for synchronous input
measurements, or update the value of the digital output
ports in the analog output stream for synchronous
waveform stimulus and control.

VIBbox-64 packages four DT9857E modules in a rugged enclosure for field use. The user can take advantage of the full
expandability of this module series in a self-contained enclosure. The use of a USB hub internal to the system allows easy
connection to the host computer through one simple USB cable. An external power supply is included.

The DT9857E provides sixteen IEPE analog inputs, 2 analog
outputs, 16 DIO, 1 counter/timer, 1 achometer, and 2
measure counters on each board set. VIBbox-64 packages
four of these to bring the channel count to: 64 IEPE analog
inputs, 8 analog outputs, 64 DIO, 4 counter/timer, 4tachometers, and 8 measure counters. For more informationon the DT9857E module, visit our web site: www.mccdaq.

Channel Expansion
If desired, you can connect up to four VIBboxes together
to synchronize up to 256 analog inputs,8 analog outputs,
128 digital input lines, 128 digital output lines, 16counter/timers, 32 measure counters, and 16 tachometer
inputs.
Any VIBbox model can be connected together formaximum flexibility. For example, if 80 analog input
channels are required, users can connect one VIBbox-48
and one VIBbox-32 together.

VIBboxes are connected together by attaching an EP377
Trigger Bus cable from the Sync Bus connector of one VIBbox
to the Sync Bus connector of the next VIBbox. Each VIBbox
must be powered using an external power supply andconnected to a USB 3.0 port of a host computer.

QuickDAQ with Advanced FFT Analysis
QuickDAQ with Advanced FFT Analysis is a ready-tomeasure application package that ships free with VIBbox.
Combine QuickDAQ with VIBbox to acquire data, record
data to disk, analyze the data, display the results in botha plot and digital display, and read a recorded data file.
Data can be exported to other applications like Microsoft
Excel® and The Mathworks MATLAB® for moreadvanced analysis.

A maximum of four VIBboxes, in any combination of VIBbox
models, can be connected together to expand the number ofchannels.

All channel data is available at the same time due to thesimultaneous operation and parallel configuration of theI/O circuitry. This parallel measurement capability assuresthat vibration data can be analyzed at the same instantin time without the time lapse and phase difference ofmultiplexed systems.

Key Features• QuickDAQ with Advanced FFT Analysis

When multiple VIBboxes are connected together, users
can achieve a maximum throughput rate of 51.2 kS/s
on each channel. IEPE inputs from sensors such as
microphones, accelerometers, and other transducers thathave a large dynamic range can be connected directly
and measured at this very fast throughput rate.
