Monitor

The user has a choice of high resolution EEG monitors:
17-inch or 19-inch. Both monitors display data at a

resolution of 1024 x 768 pixels.
The VikingSelect can be also obtained with either a 15-

inch or 18-inch flat panel display.

Networking

Networking on the VikingSelect is accomplished by
integrating the network card into the Intel PIII
motherboard.

FireWire Card

FireWire is a cross-platform implementation of the
high-speed serial data bus, as defined b y I EEE Stan dard
1394-1995, that can move large amounts of data
between computers and peripheral devices. It features
simplified cabling, hot s wapping, and transfer speeds o f
up to 400 megabits per second.

FireWire supports two types of data transfer:
asynchronous and isochronous. Traditional computer
memory-mapped, load and store applications makes
asynchronous transfer appropriate and adequate.

One of FireWire’s key features is its support of
isochronous data channels. Isochronous data transfer
provides guaranteed data transport at a pre-determined
rate. This is especially important for multimedia
applications where uninterrupted transport of time­critical data and just-in-time delivery reduce the need
for costly buffering.

may prevent a number of other services from not
starting. Any service that has an error will be listed in
the System log with the appropriate time stamp.

The Security log is not utilized by default. If security
logging is enabled failed and/or successful logon
attempts will be displayed as dictated by the user.
Security logging can be setup in User Manager. There is
not usually a practical reason for enabling security
logging for most Nicolet networks.

The Application log records errors generated by non­operating system applications. If a Nicolet application
crashes, a Dr. Watson message appears and an entry is
generated in the Application log.

Performance Monitor

This utility will not be used very often, if ever. Only
when items such as process threads, interrupts, hard disk
caching, or network requests are suspected to be causing
a problem should Performance Monitor be used. Items
can be monitored by pressing the plus button on the
toolbar. You can then select any number of possible
items to monitor. Keep in mind that Performance
Monitor uses resources itself and will skew your results
slightly. Task manager is a better utility when basic
processor, and memory information is needed.

Windows NT Diagnostics

Other Administrative Tools

Backup and Remote Access Administration are also
included in Administrative Tools. Neither one of these
options is used because the accompanying hardware,
(tape drive and/or modem) are not available through
Nicolet at this time.

Other Windows NT Properties

Right click on My Computer and select Properties to
view the System Properties and add new user profiles.

Changing the startup boot menu

Just before Nicolet ships a system we copy its
configuration to a text file and save this file on a
Customer Support Server. This text file is created using
Windows NT Di agnostics (MSD). MSD displays a
number of registry entries in an organized graphical
manner. This includes all of the system resources, hard
disk utilization, memory allocation, page file sizes,
graphics card specifications and other configuration
information. NT Diagnostics is a viewer only; items can
not be changed in this utility. You have the option to
print this information to a printer or text file. You may
be asked to copy this info to a file for comparison to the
shipping configuration MSD report. The diagnostics
report gives us an idea if the user has modified, added or
deleted anything on the system. Diagnostics is av ailable
to all users.

Choose the Startup/Shutdown tab. You can change the
amount of time the system waits for you to make a
selection. 0 seconds will not display a menu and
automatically boots the default selection, which is set in
the Startup: field boots to this tab.

Diagnostics

Software

Overview

This Section describes the Viking Select diagnostics an d
shows you how to run them. The Viking Select built-in
diagnostics will let you test the Viking Select hardware
that cannot be tested by off the shelf computer
diagnostics. The goal of the diagnostics software is to
provide a method for a non-technical Viking Select user
to identify the malfunctioning Least Replaceable Unit
(LRU).

To access the Diagnostics, double-click on the
Diagnostics Icon on the Windows Desktop.

The system displays the Diagnostics screen.

Icon Descriptions

the diagnostic message area.
This information includes hard ­ware version, software version,
and if applicable the fire wire
node number. This test indi­cates that the hardware is
present and communicating
with the software.

continued on next page

VikingSelect Service Manual

Auto test icon. This test will
determine which tests it can run
automatically according to the
system configuration. The
diagnostics will then run a test
on all recognized boards and
the amplifier and then display
the results in the Diagnostic
Message area. To view the
details of the test, select view
from the menu bar and detail
report from the drop down list.
The board test will perform a
check of the registers on each
board, and check for a valid
version and display t he findings
in the Diagnostic Message area.
The findings will be displayed
as a pass/fail message.
The amplifier test will set the
filters to a known position. The
amplifier will generate a 20 Hz
sine wave that will be used a
calibration signal. This signal
will be applied to the non­inverting (+) input of all chan­nels. The inverting (-) input
will be connected to ground.
The diagnostics software will
measure the RMS value for
each channel. The diagnostics
will perform the test for a gain
setting at 1 00, 1000, and
10,000. The values will be dis­played if detailed report is
selected otherwise, a pass/fail
message will be displayed.

Headbox test icon. This test is
used to check the continuity of
the patient signal path. When
this test is selected, a picture of
the Headbox will appear. The
software will set the filter to a
known position and the ampli­fier will generate a 20 Hz sine
wave that is used as a calibra­tion signal. This signal is sent
to the “Check amplifier” jack
on the bottom of the amplifier.
The user will use an electrode
linker to apply the signal to
each jack of the Headbox.
The software will continuo us l y
scan the electrodes inputs and
measure the RMS value for
each channel. If a valid level is
found on a scanned input, the
associated jack on the drawing
will change to green. When all
inputs have been checked, the
Done button is clicked. If all
inputs have passed, a pass/fail
message will be displayed in
the diagnostic message area.

FW Host

This section is designed to explain the FW Host
program and to describe its uses. It is not inte nded to be
a complete manual of the FW Host program. FW Host
was developed to test the new FireWire har dware before
there was application software available to test the
hardware. FW Host can be used to perform amplifier
and electrical stimulator setup as well as acquire and
display data. There is no support for the auditory
stimulator. It is designed as a tool for hardware
diagnostics. FW Host can be used to distinguish
between hardware and software problems very quickly,
as it is a completely separate software package that can
acquire data.

FW Host is loaded on all VikingSelect systems and can
be run from Start, Programs, Nicolet, Tools, FW Host

When the program opens, a window will appear that is
divides into two parts. The lower section is used to
display data. The upper section allows for reading and
writing of data to specific memory addresses. We will
not cover this in this document. When acquiring data the
Sensitivity value can be changed to adjust the display
sensitivity of all displayed waveforms.

The program has the ability to store and recall setting
files. A few settings files are shipped with the system.
To recall a setting file click on File, Open and select a
file. In this example, we will recall a settings file for
EP8 amp cal.

Once this settings file is recalled then press on the
button to start acquisition. A waveform similar to the
following should be displayed. Press the button
again to stop acquisition. To erase the waveforms and
clear the screen press the clear button.

Adjust the amplifier settings by clicking on Setup and
Amplifier. The following window appears and allows
you to adjust the amplifier parameters.

The first tab is the Acquisition tab.
Multiplex Mode - This allows you to select which amp

is used to acquire data if more that one amp is conn ected
to the system. If only one amp is connected to the
system, it will be the only amp available. The sample
rate will be adjusted to the proper number for the amp
selected. If you choose a sample rate that is
inappropriate for the amp select, data acquisition will
not take place.

Time Base - The time base for the acquisition screen.
Time base is in full screen units, not per division units.

Sweeps to Acq - This feature is not implemented.
Inputs - The amplifier channels that will be acquired

and displayed. If the input is checked, than that channel
will be acquired. Channel 1 mu st always be enabled

for any data acquisition to take place.
Amplifier Mode - Select Normal or Calibration for data

acquisition. When Calibration is selected, the
calibration signal needs to be set up. If pulse is selected
for the calibration signal, pulse width needs to be set up.

Amplifiers

Field Service Procedures

Three amplifiers can be used with the VikingSelect:

EA-2 2-Channel Amplifier
EA-4 4-Channel Amplifier
ES-8 8-Channel Amplifier

Each of these devices amplify electrical signals
generated by a patient, provide signal conditioning, and
convert the analog patient signal to digital data to be
sent to the computer. The VikingSelect application
interprets the digital data received from the amplifier
and displays the patient data on the computer monitor.

The EA-2 and EA-4 amplifiers have input jacks for
patient interface electrodes built into the amplifiers.
The input for each channel consists of a positive ( + ),
negative ( - ), a ground (gnd), as well as a DIN input
adapter for concentric EMG needles. The EA-2 and
EA-4 also have a temperature read circuit that is active
in the NCV software. The temperature of the patient
can be recorded and may be used to correct nerve
conduction velocities. The temperature read circuit is
active in the NCV software only.

The ES-8 amplifier differs in that it only has inputs for
head box connections. The ET-16A and ET-16B
electrode headboxes have 16 inputs for patient inter face
electrodes on each headbox. The ES-8 amplifier does
not have a temperature read circuit.

The amplifiers have an internal circuit that provides
measurement of patient electrode impedance. This
value is displayed through the VikingSelect software.
When the Impedance button is pressed on the control
panel, a 20 Hz signal is sent out the ground electrode
and is measured on the positive and negative inputs
separately. The change in amplitude is proportional to
the impedance of the recording electrodes. The
impedance function is available only in a VikingSelect
waveform screen. The range of the impedance meter is

0.5K Ohms to 180K Ohms.
The amplifier has a built in Calibration signal. This

signal is a rectangular pulse that will vary in amplitude
and duration depending on the test selected. The
amplitude values are 2, 20, 200, 2000, 20000 uVolts.
When the Calibrate/Impedance button on the control
panel is pressed, the normal inputs to the amplifier are
shorted to ground and the cal-signal is used as an input
for the amplifier. The value of the cal-signal
(amplitude and duration) will be displayed on the
waveform screen. The software markers can be used to
verify the proper operation of the amplifier.

The patient analog signals are converted to digital
signals by the analog to dig ital converte r (ADC) circuit .
The ADC uses a 16-bit digitizer with a 1uV effective
time resolution. The input impedance of the amplifier is
>1000M Ohms.

2, 4 & 8-Channel Amplifiers

2-Channel Amp Inputs

The 2-Channel EA-2 Amplifier is equipped with a
temperature probe jack to measure skin temperature
during a nerve conduction study.

The 4-Channel EA-4 (not available at the time of this
printing) and 8-Channel EA-8 Amplifiers are designed
to collect patient signals from multiple electrode
locations without physical relocation of electrodes. The
VikingSelect application software automatically selects
the electrodes and retrieves the amplified patient
response.

Field Service Procedures

This section discusses the hardware and software
components that make up the system network. A
Nicolet network consists of two or more systems
connected to a hub or switch via a category 5 UTP
cable. A network stops being just a Nicolet network
when there is an additional connection to a hospital
backbone or Information System.

The network “functional unit ” consists of hardware and
software components:

• Ethernet Category 5 cable (UTP)

• Ethernet 10 or 100 Mbit Hub

• Microsoft Networking Services and Protocols

Revision 3/23/01 4 - 33

VikingSelect Service Manual

Software Components

The Windows NT operating system takes care of all
network communication. Services are loaded to support
the following Network protocols .

TCP/IP By far the most co mmon network proto-

col. Flexible, widely used and relatively
fast

NetBEUI The fastest Protocol available for Small

Microsoft Networks. This protocol works
great when there is a small number of
workstations connected on a “private” net­work. The main downfall to NetBEUI is
that it cannot be routed, making it unsuit­able for larger installations.

IPX/SPX The protocol used by Novell for connec-

tion to other Novell enabled clients and
Servers. If a Novell network is not being
used this protocol along w ith its dep endant
protocol, NWLink NetBIOS should be
removed to increase logon speed.

Network Setup

This procedure describes the steps required to set up a
Nicolet-only network and configure it to run the NicVue
patient administration database .

Items required

• Two or more systems

• One Category 5 network cable per system (max

length 100M/300ft)

• 100Mb or 10/100Mb switchable hub or switch, with
as many ports as needed (typically four or eight)

• Valid IP addresses for each system (discussed on the
following page)

4 - 34 Revision 3/23/01

Field Service Procedures

Configure Network Services & Protocols (All
Stations)

NOTE:
If your Nicolet network will connect to an existing

hospital backbone or information system, the
hospital IS department should configure the network
services and protocols.

Step Action

1. Right click on Network Neighborhood,

select Properties.

2. a. From the Identification tab, enter a

unique Computer Name that best
describes the individual system
(i.e.WORK1).

b. Make sure the Workgroup is the same

across all systems (usually Nicolet). A
domain can be used if the facility wants
to manage this, but it’s not necessary.

3. a. From the Protocols tab, highlight the

NetBEUI protocol and click on Remove.

NOTE:

Perform steps 3b-3d ONLY IF no
integration is required with a Novell server
or network.

b. If IPX/SX and NWLink are listed under

Protocols, click on the Services tab.

c. Highlight and remove Cl ient Servi ces for

Netware.

d. Go back to the Protocols tab an d remove

IPX/SPX and NWLink. The only
remaining protocol should be TCP/IP.

Step Action

4. a. From the Protocols tab, highlight TCP/IP

and select Properties.

b. Verify that Specify an IP address is

selected.

c. Specify an IP address of 192.168.1.x,

where x is a unique number from 1-255.
(The ReVue station is usually

192.168.1.1, and the Acquisition sta­tions are.2, .3, .4, etc.)

d. Verify identical Subnet Masks;

255.255.255.0 is the default and should
be left that way.

e. The Default Gateway should be left

blank.

f. All other tabs in the TCP/IP Properties

window should be left blank and in their
default state. This may result in an error
message about WINS not being config­ured on an adapter. If this message
appears, click on OK and finish closing
the TCP/IP Properties window.

5. Click on the Services tab and verify that all

necessary services are installed. The six
default services are:

• Client Services for NetWare (As
mentioned above, if you are not
connecting to a Novell network, you
should have already removed this
service.)

• Computer Browser

• RPC Configuration

• NetBIOS Interface

• Workstation Service

• Server Service

6. Click on the Adapters tab. The default

adapter is the EtherExpress Pro.

7. The Bindings are automatically set up by

Windows NT and sho uld not be modi fied.

Set up Shares and Verify Network Connections
(All Stations)

Step Action

8. Click on OK to close the Network window

and reboot.

9. Repeat steps 1-8 for each computer on your

network. Your computers should now be
ready to talk on the network

Verify Network Cabling

Step Action

1. Plug one end of the network cable into the

system’s network card and the other end
into a numbered port on the hub. Some
hubs/switches have an Uplink port; systems
should not be plugged into this port.

2. With the systems and the hub powered on,

verify the Link indicator lights on the hub
and network cards are illuminated

3. If plugging into a wall jack instead of a hub,

make sure the port is active. You may need
to involve the IS department for this step.

4. From Windows NT Explorer, verify the

D:\Nicolet share is set up at each station.
Right click on the D:\Nicolet folder and
select Sharing to enable the share if it is not
already set up.

5. Verify that the systems can see each other

through Network Neighborhood.

6. If a system does not appear, do a Find Com-

puter search for it Right click on Network
Neighborhood, select Find Computer from
the drop-down menu, then enter the com­puter name you are looking for.

7. Try pinging any computers that don't show.

If they don't ping, troubleshoot the network.

8. After all computers appear on the network

and have the Nicolet share folder available,
open NicVue to start configuration.

NicVue Setup

Refer to the NicVue Software G uide (P /N: 26 9-5377 02)
for information on a common database, when
connecting Viking Selects to a network.

Set Up the Main Database (ReVue Station or
Server)

NOTE:

Perform steps 9-12 ONLY on the system holding the
Main Database.The Main Database typically resides on
a ReVue station or Server. Choose a system that will

always remain ON.

Step Action

9. Select Tools/Database/Settings. The pass-

word is Nicolet.

continued on next page

4 - 36 Revision 3/23/01

Field Service Procedures

Set Up the Databases (Acquisition Stations

NOTE:

Perform steps 13-16 on ALL acquisition systems.)

10. Each acquisition system requires a pointer

to the Main Database on the ReVue system
or Server. You can either type in the path if
you know it (for example \\Review\Nico­let\Npa\Npa.mdb), or you can click the
Browse button and find the file in Network
Neighborhood.

11. On each Acquisition system, make sure that

the options Use Local Database file and
Update Local DB file on Exit are both
checked.

12. The Local Database file should be listed as

D:\Nicolet\Npa\NpaLocal.mdb.

13. Verify everything is correct and click OK.

Verify the Device Configuration Manager (DCM)
Settings (All Stations)

NOTE:

The DCM settings are unique for each station, and mus t
be verified or, in some cases changed.

Step Action

Step Action

18. If data is going to be stored directly to the

Server, add a selection for the server. The
entry will look like: Host = \\Server Path =
\\SharePath and No drive letter . Because the
server will not automatically have a path set
up for the Nicolet applications, you may
need to create a directory and share path.
We recommend that you use the same share
structure that was set up on the Acquisition
systems (\Nicolet as the share folder and the
necessary folders under that, for example,
\EEG, \LTM, \NPA, \V ikDir) This setup will
make data flow more seamlessly to NicVue
and allow you to use the default share paths
listed in the NicVue DCM.

19. Click on the Network Systems tab. The Net-

worked systems listed apply to ALL com­puters sharing the Database, so they only
need to be set up once for all systems.

20. Click the Insert button and a line opens up

in the Systems List. Click the Browse but­ton next to Computer Name and select a
computer from the list. Leave the label the
same as the computer name.

21. Click Insert again and repeat the process

until all computers, Including the local
machine, are listed in the Network Systems
Tab. Accept and exit.

14. Select T ools/System Setup. Th e password is

Nicolet.

15. From the Utilities Tab select DCM.

16. If the Computer name has changed make the

necessary changes to the Host Name of the
DCM section. This will reassign the Label
so that it functions correctly.

17. By default, there should be an entry for the

local data storage path on the D:\ partition
and a selection for the CDR. Unless data
will be stored directly to a remote server
these are the only two selections that are
needed.

Field Adjustments/Maintenance

There are no field adjustable components associated
with the network. If network problems occur, check the
physical connections, cables, ports, and connectors.

Testing/Troubleshooting

TCP/IP provides some utilities to help diagnose and
isolate network problems. Additional 3rd party
troubleshooting tools can also be utilized.

Ping

The Ping command is used to send a small signal to a
known address to get a resp onse. If the remo te computer
is available on the network it will send a response back
to the local computer and display the transmission time
on the screen.

IPconfig

This command lists the local machine’s IP address,
subnet mask, and default gateway.

Ipconfig /all

The /all switch lists all of the settings that IPconfig does,
but adds a description of the network adapter, the
physical (MAC) address, and lists the status of network
services such as DNS and DHCP, as they pertain to the
network adapter.

29. Resize your screen areas appropriately.

Test the Setup

30. Add a new patient and run a test.

4 - 38 Revision 3/23/01

ARP - Address Resolution Protocol

ARP is the utility that resolves IP address to the physical
MAC address. You can display a list of cached MAC
addresses by typing ARP -a at the DOS prompt. If ARP
is not functioning, resolution doesn’t occur and
communication cannot take place via IP address.

Field Service Procedures

Invalid DCM Error Message

This error typically appears if you change the computer
name in NT after configuring the system. The identical
computer name must be set in NicVue and the installed
Nicolet acquisition and review applications:

Step Action

1. From the NT desktop, double click on My
Computer/Control Panel/Network. Ver-

ify the correct Computer Name and the
Workgroup Nicolet.

2. Open NicVue. Select Tools/System
Setup/Utilities/DCM. Select the correct
System Name from the drop-down menu.

Click on OK to close the window.

3. Open the VikingSelect application. Click
on the Preferences icon (computer). Click
on the Paths tab, and select the the correct
computer name from the Acquisition Data
Files Path drop-down menu. Click on OK
to close the window.

Collisions

The number of times two or more LAN cards have
attempted to access the network simultaneously. A high
value usually indicates a busy network. It can also
indicate that you have used an unsupported type of
coaxial cable, too long of a cable, or have not placed
terminators on the end nodes. In rare cases, a
malfunctioning LAN card continuously transmits noise,
resulting in a high number of collisions.

Bad Transmissions

The number of unsuccessful tr ansmissions. A high valu e
generally indicates cabling or hardware problems.

Good Transmissions

The number of successful transmissions. A low value
could indicate a LAN card is not efficiently receiving
network data. In such cases, test this LAN card with
only a few other LAN cards to make sure this low value
is not a result of poor transmissions from another
network card.

4. Open the Viking Review (or other ReVue)
application. Click on the Preferences icon
(computer). Click on the Paths tab, and
select the the correct computer name from
the Review Data Files Path drop-down
menu. Click on OK to close the window.

Network Vocabulary

CRC Errors

A hardware-generated error associated with corruption
of data as it passes through the network. A high value
could indicate that a LAN card is not correctly
transmitting data. It might also indicate that faulty
cabling or electrical noise is corrupting the data in
transit.

Alignment Errors

A hardware-generated error associated with
misalignment of data as it is received. A high value
could indicate cabling or hardware problems.

Good Receives

The number of successful receives.

Retransmissions

The number of times a retransmission was necessary
due to an error.

Resource Exhaust

The number of times the PC could not receive a packet
because there were no buffers available to receive the
data. A high value could indicate that your computer is
continually running out of buffers. If this is the case, call
Product Support.

Field Service Procedures

Auditory Stimulator

The Auditory Stimulators and components are:

• Auditory Stim Board

• Unshielded TDH-39

• Shielded TDH-39

• TIP 300 Tubal Inserts

• Bone Vibrator

Auditory Stim Board

The Auditory Stim Board provides the circuitry to
initiate an auditory stimulus.

Troubleshooting

The most efficient way to check the Auditory b oard is to
swap the headphone cable plugs in the Auditory Stim
boards’s jacks.

• If no sound comes out of one of the ear phones after
swapping the cable plugs, the board may need
replacing.

• If sound is produced in the other ear phone, the
headphones should be replaced.

A much more accurate method to verify a board
problem is to use the VikingSelect Evoked Potential
Software and headphones. This method effectively
checks basic parameters such as stimulus type
(click/tone/noise) and stimulus delivery (left/right ears).
However, this method does not reliably test parameters
such as stimulus intensity and click polarity.

The auditory board is calibrated at the factory. The
output intensity is measured electrically, using two

Ω fixed resistors. These resistors are connected

300
differentially to one of the headphone outputs.

Hardware Components

The Auditory Stim board is a LRU and has no
replaceable parts or peripheral components.

The Software Components

The Nicolet VikingSelect application controls the
Auditory Stim board. No additional software is
required.

Field Adjustments/Maintenance

The Auditory Stim board has no field adjustable
components.

Step Action

1. Set the following AEP parameters as shown

below.

• Stimulus Type = Burst

• Stimulus Intensity = Maximum

• Rate = 10 Hz

• Frequency = 1 kHz

• Test Ear = Both (L&R)

2. Set up the oscilloscope following step 6 in

the section, “Electrical Stimulator A” (see
Chapter 5, “Electr ical Stimulator A” on

page 5-10). Adjust the voltage range to

5V/div.

3.

Insert the 300
phone jack on the right side.

4. See the table in the next column for the

Troubleshooting

When troubleshooting the 2-channel electrical
stimulator sub-system, the fault can be one channel, or
both channels. The normal fault is the absence of
electrical stimulus output. If the stimulus output is
present, but suspected not to be at the correct intensity
or duration, verify the output in accordance with ch apter
5 page 5-10.

To verify the IES-D9 relay unit and control box are
functioning properly, the stimulus must be routed to
each output jack pair on the relay unit. This can be done
by placing the Manual/Remote switch to Manual and
setting the dial on the control box to route the stimulus
to the pair of jacks being tested. This can also be done
with the control box in Remote, but the user must set the
software to direct the stimulus to the pair being tested.

While troubleshooting the IES-D9, the indicator that
will help to determine the faulty component is the LED
on the IED-D9 Control Box. The LEDs on the Control
Box are lit by the electrical stimulus passing through the
Control Box. The stimulus must be >0.8mA for the
LEDs to light. By checking the LED and the output
from the Relay Box , the faul t can be narrowed down to a
single component.

The following steps are for a fault that results in no
output from one stimulator. To follow this procedure
both channels of the electrical stimulator must be active
with an output >1.0mA. Shut down the system prior to
removing or attaching any cables. Never troubleshoot a
system that is connected to a patient.

Field Service Procedures

Step Action

1. With both channels of the electrical stimula-

tor active, check the LEDs on the IES Con­trol box. If the LEDs are lit with no output,
continue with step 5. If the LED’s are not
lit, continue with step 2.

2. Shut down the VikingSelect and swap one

end of the SC101/102 cables between the
electrical stim board and the IES control
box. This will direct the stimulus from
channel 1 of the stim board to the input of
channel 2 on the control unit.

3. If the fault is with the Electrical stim board

or SC101/102 cables the LED that did not
light will change sides. If initially channel 1
would not light and now channel 2 will not
light, the fault is with the Electrical stim
board or SC101/102 cable.

4. If the same side LED is not lit, the fault is

with the Relay Box, Relay Box cable, or the
Control Unit. Replace the SC101/102
cables to the original positions and continue
with step 5.

5. Shut down the VikingSelect and swap the

relay box cables at the output of the IES
control unit. This will direct the stimulus
from channel 1 on the e-stim board to R elay
Box 2 and the stimulus from channel 2 on
the e-stim board to relay box 1.

6. Check the output at the Relay Box and ver-

ify that the fault changed sides. If initially
the fault was on Relay Box 1, now the fault
should be on Relay Box 2. If the fault
changed sides, the fault is on the side with
the Relay Box Cable or Relay Box that has
no output.

7. Swap the Relay Box cable (at both ends)

with the known good cable from the other
side to isolate the fault to the Relay Box or
the Relay Box cable.

8. If the fault did not change sides when the

relay box cables were swapped, the fault is
with the Control Box.

Revision 3/23/01 4 - 52

Field Service Procedures

The following example will troubleshoot a problem with no output from Relay Box 1. The LED for channel 1 will

When the electrical stimulator is active the same symptoms occur: LED for channel 1 is not flashing and the LED for
channel 2 is flashing. There is no output from Relay Box 1. This shows that the fault is not with the electrical stim
board or the cables between the electrical stim board and the IES-D9 control unit.

Return the cables between the electrical stimulator board and the IES-D9 control unit to the o riginal p osi tions. Now,
swap the cables between the IES-D9 control unit and the relay boxes.

Because the fault stayed with Relay Box 1, the fault is with the Relay Box or the Relay Box Cable. The Relay Box
Cable can be swapped with the known good Relay box cable connected to Relay Box 2 to eliminate it as the faulty
component.

The S403 Probe is used in contact with the patient’s skin
to deliver a low current, microvolt pulse. This pulse of
current stimulates the patient’s muscles to initiate an
electromyographical response.

Hardware Components

The S403 Probe is a LRU and has no replaceable parts
or peripheral components.

Software Components

The Nicolet VikingSelect application controls the S403
Probe. No additional software is required.

Field Adjustments/Maintenance

The S403 Probe requires no adjustment or maintenance.

Troubleshooting

Step Action

1. Connect the S403 current probe to the

STIMULATOR 1 jack on the stimulator
box.

2. Test the probe in both REMOTE and CON-

SOLE modes from the VikingSelect system
application (console mode only with the
IES-D9).

3. With no load conn ected to the current probe,

turn the% CURRENT CONTROL knob on
the probe from 0% to maximum and watch
the VikingSelect display screen. The
IMPEDANCE LIMIT message on the
screen should turn OFF when 0 mA is
selected and turn ON before 2mA is
selected. Verify that the IMPEDANCE
LIMIT message stays ON through the maxi­mum range.

4. Adjust the output dial on the probe and

place the prongs to your palm. A small elec­trical charge should be felt.

5. If no charge is felt, test the 405 using elec-

trodes and electrode leads.

6. If an output is produced using the electrodes

and leads, but not with the probe, replace
the probe.
