Quick Setup Guide
The vibration control system software runs on several different hardware
platforms from Crystal Instruments:
•Spider-81: an 8-channel device that can be expanded to a system with
hundreds of channels
•Spider-81B: a 4-channel economic version of Spider-81
•Spider-80X: a compact packaging of Spider-81 that can be expanded to a
system with hundreds of channels
•Spider-20: a 4-channel handheld Wi-Fi enabled signal analyzer and data
recorder
When there is no confusion, this manual refers the hardware platforms above as
“Spider”. When the description is specifically related to a type of hardware, the
product model number will be mentioned.
Important Safety Information
The Spider product complies with:
EN 61326:1997+A1:1998+A2:2001
EN61000-3-2: 2000 & EN61000-3-3: 1995+A1:2001
The Spider and its accessories should be used only as specified in this User’s
Manual or the warranty protection provided by Crystal Instruments may be void.
Condensation may form on the circuit boards when the device is moved from a
cold environment to a warm one. In these situations, always wait until the device
warms up to room temperature and is completely dry before turning it on. This
acclimatization should take about 2 hours.
For the most accurate measurements, a warm-up phase of 20 minutes is
recommended.
These devices have been designed for use in clean and dry environments. They are
not to be operated in 1) exceedingly dusty and/or wet environments, 2) in
environments where danger of explosion exists, and 3) in environments
containing aggressive chemical agents.
Always lay cables in such a manner as to avoid tripping hazards.
A Warning identifies conditions and actions that pose hazard(s) to the user. A
Caution identifies conditions and actions that may damage the instrument.

Spider DSA User’s Manual
11
To avoid electrical shock or fire:
1. The Spider is a low voltage measurement instrument.
2. Do not apply input voltages above the rating of the instrument. Never
apply a voltage that potentially exceeds ±20 V.
3. Review the entire manual before using the instrument and its
accessories.
4. Do not operate the instrument around explosive gas or vapor.
5. Before use, inspect the instrument, BNC connectors and accessories
for mechanical damage and replace if damaged. Look for cracked or
missing plastic. Pay special attention to the insulation surrounding
the connectors.
6. Remove the cables and accessories that are not in use.
7. Use the ground input only to ground the instrument. Do not apply
any voltage.
8. Do not insert metal objects into connectors.
9. Use only the wall-mount AC Adapter provided by Crystal
Instruments.
AC Adapter Voltage Range
For external power sources theSpider-80X uses a wall-mount AC adapter. The AC
Power range is: 100 –240VAC, 47 –440 Hz.
Maximum Measurement Input Voltage
The maximum working input voltage is 20 V peak. Voltage ratings are given as
“working voltage”. They should be read as Vpeak for dynamic applications and as
VDC for DC applications.
The maximum input range without damaging the hardware is40Vpeak.
Connecting Your PC to the Spider Front-End
You can connect the Spider modules through an Ethernet LAN or
directly to your PC using an Ethernet crossover cable. There is a CAT-5
100Base-T jack on the rear of the modules.
If your Spider system consists of more than one module, you will need to connect
the modules with a network switch or router. It is recommended that your system
use a private LAN rather than a shared office LAN. Spider hardware supports
IEEE 1588 time synchronization. To scale the measurement system with more
than one Spider unit, an Ethernet switch supporting IEEE 1588 is highly
recommended.

Spider DSA User’s Manual
12
Figure 1: Topology
Set Master or Slave Mode
The M/S switch on the back of each unit is used to control whether it
is configured as a Master or a Slave. For a system with multiple units,
only one can be configured as a Master, and all others must be set as
Slaves.
If you are using only one module, the system will automatically configure it as a
Master regardless of the switch position. If additional modules are added later, it
will be necessary to configure the first module as the Master and each of the
additional modules as Slaves.
Connect the Power Adapter
Connect the power adapter to the power jack on the rear of the device and to an
AC power source. The power adapter is an AC to DC converter that accepts 100 –
240 VAC (47 –440 Hz) and outputs 15VDC. The total power consumption is less
than 10 watts during full operation.
Turn Spider Power On
After the Ethernet cable and power adapter are connected to the Spider, press the
Power button on the front of the unit. The LAN LED will illuminate.
IP Setup
When each Spider is shipped, unless the user has requested otherwise, it is set by
default to the Dynamic Host Configuration Protocol (DHCP). If no DHCP server
is found when Spider is connected to a PC or LAN, the device will resort to a link-

Spider DSA User’s Manual
13
local address auto configuration. In this mode, the device randomly chooses
an address in the 169.254.x.x address space.
Since all this happens automatically, the IP settings of the Spider modules should
not need to be manually set.
If a static IP configuration is required, IP settings of the Spider can be changed
with the Front-End IP Address Setup Tool that was installed with EDM. This
tool is in the EDM installation folder. It is called “Front-End IP config.exe”.
Figure 2: Set Device IP Address
Each connected hardware module will be listed by serial number. To change
settings, select a module, enter the desired IP address, subnet mask, and default
gateway, and click Set static IP address. You can also choose to have the IP
settings automatically assigned via DHCP by clicking Enable DHCP. The LED
on the Spider will flash for a couple seconds, indicating that the new IP has been
assigned. It is helpful to keep track of the IP address of each module and its
physical location.
Resetting to Factory Default IP Settings
To reset to the factory default IP address of 192.168.1.153 for the Spider-80X,
press and hold the Reset button on the back of the unit for 4 seconds.
For the Spider-81, it is recommended to use the front panel LCD and menu
buttons to make changes to the IP settings.
Computer Network Settings
The network settings on the PC must have a matching subnet and subnet mask in
order to communicate with a Spider module. If both the computer and the Spider
module are set to use DHCP, then they will automatically configure matching IP
addresses with the correct matching subnet settings.

Spider DSA User’s Manual
14
To verify the network connection, use the PING command in the Command
Prompt window on the PC. In the Windows Start Menu, select Run, type ping
192.168.1.182 (the actual IP of your Spider), and press enter.(Note: replace the
factory default IP, 192.168.1.182, with the actual configured IP address of the
device.
If it is correctly configured, the ping command will receive responses, as shown
below.

Vibration Visualization
ODS window is available in all the three test types of EDM Spider DSA software.
This option provides fast and efficient structural model generation and full 3D
visualization of the structure under test.
The base elements (points, lines, and surfaces) can be added/deleted graphically,
or through typed Model Editor entry. Components can be specified for each part
of the structure when they are created. Each component can have its own origin,
as well as its directions and Euler angles. The basic component library includes:
line, plane, cube, cylinder and sphere. Any of these can be added to the geometry
model by specifying origin, direction, dimensions, and the number of cells of the
component.
The geometry model can be saved and later recalled by other tests. Also, the
model can be cleared when the user wants to start over with a new geometry
model for the structure under test. Several types of format from 3rd party
applications are supported for geometry model import. The Universal File Format
(UFF) format of point and line models is widely used, may be imported to EDM
DSA Operational Deflection Shape.
Editor is designed to help users to create the geometric models for viewing the
operational deflection shapes of the test structure including adding and deleting
the points, lines, surfaces, cubes, spheres, and cylinders.
Figure 223. An Overview of Editor
On above Editor tab window, there are icons on the left side of the window, as
well as icons on the top of the window. The left side one icons are grouped for the

icons related to create, edit, remove or save the model. While the icons on the top
side are related to the display of the geometry model.
Here’s the example of creating a geometric shape as shown above. Click the Add
Object button and then click the Add Panel button.
Figure 224. Add Panel Window
Choose the panel direction as X-Y. Therefore, the panel created will be on the X-Y
plane. Origin of X, Y, and Z is the initial center coordinates of the panel. User can
choose to add a displacement to either direction if necessary. Size is the total
width and height of the panel. Cell defines the number of cells along each
direction. Rotate is the rotational movement on specific axis such as XY axis, XZ
axis, and YZ axis. With above parameters set, press OK to finish creating such a
geometric shape.
Click the Perspective button on the top right corner of the graph window to
display a 4-pane view window as shown below.

The first group icons on the left side of the Editor window can be used to
add/remove object to/from the model graphically.
Following 3 toggle buttons are used to specify the object type to be operated on,
Point
Line
Surface
Only one of the above objects can be selected. The selection of the other one, will
disable the previous selected one.
Add object
This is a toggle button too. When it is toggled on, the selected Point object will be
added to the graph area by a left mouse click.
For the case of Line object is toggled on, left mouse click the starting point, and
drag to the next point, followed by a left mouse click, will create a line between
these two points.

Spider DSA User’s Manual
18
Similarly, for the Surface object, left mouse click the first point, drag to the second
point, left mouse click, and drag to the 3rd point, will create a triangle surface.
Remove object.
To remove an object graphically, first select the object type, i.e., point. Then, on
the geometry model, left mouse click the object which needs to be removed. The
selected object will be highlighted as red. Now, click the “Remove Object” button
to delete the object. Note: when a point is removed, the related lines and surfaces
will be removed too!
