ProComp Infiniti Hardware Manual 7

Introduction
The ProComp Infiniti™ encoder is an eight (8) channel, multi-modality device for real-time
computerized biofeedback and data acquisition. It has 8 protected pin sensor inputs with two
channels sampled at 2048 s/s and six channels sampled at 256 s/s. The ProComp Infiniti encoder
is able to render a wide and comprehensive range of objective physiological signs used in clinical
observation and biofeedback.
The ProComp Infiniti basic package includes the following hardware:
One eight-channel ProComp Infiniti encoder unit
One TT-USB interface unit
A supply of fiber optic cable (1’ and 10’ cables)
Four alkaline ‘AA’ batteries
Thought Technology’s advanced design and active electronic sensors meet exacting standards for
instrument accuracy, sensitivity, durability, and ease of use. All sensors are completely non-
invasive and require little or no preparation for use. Depending on the software being used with
the ProComp Infiniti encoder, these may include sensors specialized for:
Electromyography (EMG) Electrocardiography (EKG)
Electroencephalography (EEG) Skin Conductance
Skin Temperature Voltage Isolation
Respiration waveform, rate, and amplitude
Blood Volume Pulse waveform, heart rate, and
amplitude (BVP)
Goniometer
Force
Torsiometer
The sensors pass signals to the host computer via the microprocessor-controlled ProComp Infiniti
encoder unit. The encoder samples the incoming signals, digitizes, encodes, and transmits the
sampled data to the TT-USB interface unit. A fiber optic cable is used for transmission, providing
maximum freedom of movement, signal fidelity, and electrical isolation. Cable lengths up to 25
feet can be used without signal degradation. A unique feature of the system design allows inputs
to accept any sensor, interchangeably (except the raw EMG MyoScan sensors which are used on
channel A and B). This allows a wide variety of configurations to be created by simply changing
the sensor types.
The TT-USB interface unit is connected to one of the host computer’s USB ports. It receives the
data arriving from the encoder in optical form and converts it into the USB format to
communicate with the software.
Please note, some hardware features may not be supported by all software programs. Consult the
software manual for a full list of features supported.
ProComp Infiniti Hardware Manual 8

Please note, some software programs will not function with a TT-USB, but require use of a PRO-SB in
its place.
Connecting the Encoder,
TT-USB and Sensors
SETTING UP THE ENCODER UNIT
Cut a convenient length of fiber optic cable cleanly and evenly using a sharp blade, or use the
whole length rolled up out of the way.
IMPORTANT: Winding the fiber optic cable in a loop smaller than 4 inches (10 cm) or bending it sharply
will damage the cable!
1. Plug the USB cable connected to the TT-USB interface unit supplied with the USB
connector on the computer being used. (If using the BioGraph®2.1 software please use
the Pro-SB in place of the TT-USB as described in the BioGraph®2.1 software manual.)
2. Insert one end of the fiber optic cable into the optical receiver jack on the rear face of
the TT-USB Interface unit and the other into the optical transmitter jack on the front of
the ProComp Infiniti encoder. Before inserting the cable, it may be necessary to loosen
the jack heads by turning them counter-clockwise.
3. Ensure that both ends of the optical cable are inserted all the way (about ¾ of an inch,
1.9 cm) into the jacks and that the heads are screwed down firmly.
4. Wind excess fiber optic cable into a large loop (approx. 6 inches, 15 cm).
5. Plug the sensors you wish to use into the input jacks on the front of the encoder unit.
6. Load four 1.5 V Alkaline or rechargeable Nickel-Metal Hydride (NiMH) batteries into the
encoder unit’s battery pack; check battery orientation being sure to respect the polarities
indicated on the inside of the battery compartment.
7. Push the encoder unit’s power button for 1 second.
8. Check that the encoder’s blue ‘ON’ indicator directly above the ON button is lit; if it is
not, check the condition and orientation of your batteries.
9. To switch the encoder ‘OFF’ push the power button for 1 second and ensure that the
blue indicator is no longer lit.
You may leave the encoder unit power ON if you intend to continue on to the following sections.

TT-USB Installation Notes:
The TT-USB unit is a Plug and Play device (PnP) i.e., oversimplified, Plug-and-Play automatically
tells the software (device drivers) where to find various pieces of hardware (devices). The driver
for the TT-USB is installed along with the BioGraph Infiniti Main Application software. Therefore,
before you could use the TT-USB with your ProComp Infiniti encoder the Biograph Infiniti
Software must be installed on your computer.
In Windows XP screens similar to the one below may appear.
Windows should recognize when new
device is plugged into one of its USB
ports
Let windows install the software
automatically
If the BioGraph Infiniti Software was
already installed on you computer
Windows® will automatically install
the proper drivers.
Unsigned Driver Messages
Microsoft uses digital signatures for device drivers to let users know that drivers are compatible
with Microsoft® Windows® XP, Windows 2000. A driver’s digital signature indicates that the
driver was tested with Windows for compatibility and has not been altered since testing.
ProComp Infiniti Hardware Manual 10

If a driver is “unsigned” (indicating that certification of the driver by Microsoft was pending but
not yet complete at the time of release), you might see one of the following warnings during
driver installation or update.
•Digital Signature Not Found warning. Click the Yes button to complete the driver
installation.
•On Windows XP systems, a Hardware Installation or Software Installation warning that
the software has not passed Windows logo testing to verify its compatibility with
windows XP. Click the Continue Anyway button to complete the driver installation.
Windows 2000 and XP have a new feature that controls the installation of unsigned device
drivers. There are three settings for Driver Signing:
•Block: This will prevent the installation of unsigned drivers.
•Warn: This will prompt the user whether to install an unsigned device driver or not.
•Ignore: The system will install unsigned drivers without prompting the user.
The TT-USB device drivers are unsigned and you may need to set your system to Warn or
Ignore. The rest of this section describes how to do that.
First, locate the My Computer icon on
the desktop or in Windows Explorer.
Right-click on the My Computer icon
and select Properties.
Windows XP
After clicking on the Hardware tab
your screen should look like one of the
two screens shown. Now click on

Battery Placement
Opening The Compartment
Looking at the underside of the ProComp Infiniti device, you will
see a long door in the plastic enclosure. Holding the encoder
with the connectors facing you and with the door up, push lightly
down and back with your thumbs on the door to slide it open.
Attention:
The internal workings of the ProComp Infiniti encoder is not intended
to be opened for repair except by qualified service personnel. The
tamper-evident seal under the batteries in the battery compartment
should not be removed or broken. Thought Technology may refuse to
honor the unit’s warranty if the seal is broken.
Polarity
When the compartment cover has been slid out, place four AA batteries in the slots, observing
the polarity as illustrated. Please note that a diagram of the correct battery polarity is embossed
on the inside surface of the compartment.
Closing The Compartment
Slide the door back into the ProComp Infiniti case, gently pushing it in until you feel the click of
the locking mechanism.
Keeping An Eye On The Battery Level
Since each sensor draws a small amount of power from the batteries when connected to the
ProComp Infiniti, it is better to connect only the sensors that are going to be used for a session
before you start recording; this will ensure maximal battery life. Most Thought Technology
software applications will display a battery power indicator; we recommend that you replace the
batteries as soon as this indicator falls below about 50% of the battery power.
COMPACT FLASH
The compact flash (CF) is used as an alternative storage medium for
data being recorded by the encoder. The CF card is a small square
approximately the size of a box of matches and is inserted into the
rear surface of the encoder with its label facing up. The encoder is
delivered with a protective insert in the compact flash slot. To
remove it, push the button next to the slot once to eject the button,
then push again to remove the card, pushing the button back in.
The CF card can then be inserted; you will notice that the CF card
can only be inserted one way into the encoder to protect from
incorrect insertion. When inserted properly it will be flush with the
encoder rear. Follow the procedure above to remove this card when
no longer required, and re-insert the protective insert. CF cards
require a CF card reader to transfer data to the PC. The CF cards
and reader can be purchased from most computer stores. Before its
ProComp Infiniti Hardware Manual 14

first use in the encoder, a CF card requires PC formatting using the
file manager. With the CF card inserted into the reader connected
to the PC, from Windows open the file manager and identify the
Removable Drive. Right click the removable drive and select
Format.
Select Format Type Full, if using Windows® XP select file system FAT not FAT32 and select
Start. When this is complete use the single master file build function provided by the Infiniti
Software to finish the process.
It is recommended that you temporarily disable any virus scanning utility while formatting the
Compact Flash as this will considerably increase the speed of the process.
Attention:
Formatting CF Card with File System other than FAT will render it Inoperable.
Users should follow the appropriate procedures used for disconnecting peripheral devices when
unplugging the Compact Card from its PC reader.
Compact Flash Setup
Compact Flash Rebuilding
To rebuild the Compact Flash for use in the encoder, follow these steps:
1. Place the CF card in the CF Card Reader connected to the PC.
2. From the Infiniti software's main screen, select "Compact Flash Options", and then
"Rebuild Compact Flash".
3. Select the "Create" option and press OK. Wait for the operation to complete. This may
take some time, especially for larger Compact Flash cards.
4. After the operation has concluded, you may remove the CF card from the reader. It is
now ready for use in the encoder. However, you may wish to first initialize the Compact
Flash card so that the encoder's date and time will be set (see below).
ProComp Infiniti Hardware Manual 15

Attention:
Never use a CF card previously used with other devices for recording with the ProComp Infiniti. Thought
Technology’s rebuilding process creates a single file on the CF card. Do not delete or overwrite this
file, or attempt to create any other files on the Compact Flash once it has been formatted!
If the Thought Technology format file is overwritten or deleted, the CF card may need to be re-formatted
first to it’s original PC format, using the Format facility of your PC’s operating system. If you need to do
this, choose the FAT16 file system for best results. After doing this, use the Thought Technology
rebuilding option again. If you are unsure how to do this operation please contact technical support for
more information.
Encoder Time Setting
The encoder has an internal clock to enable time and date stamping of the sessions recorded
onto the CF card. The encoder will retain its time and date when batteries are changed
if the fresh batteries are inserted within 30 seconds of removing the old ones. If the
time is lost it will reinitialize to January 1 2000. As part of the CF formatting procedure you may
wish to set up the date and time for the encoder, so that sessions can be time stamped for future
reference.
To set the date and time follow these steps:
Insert the CF card into the CF card reader
If not already selected, from the Infiniti software’s main screen, select “Compact Flash
Options”. Then select “Set Compact Flash Date/Time”.
Specify a date and time, a brief period in the future, when you will insert the Compact
Flash in the encoder. Press OK and wait for the operation to complete.
If off, turn on the encoder. Remove the CF card from the reader and as close as
possible to the specified time, insert it into the encoder. The time setting will
immediately take effect, and will set the encoder’s internal clock to the specified date
and time.
Questions And Answers About Compact Flash Time-Setting
Question My batteries have died in my encoder. Will I need to reset my encoder time and
date?
Answer No. Old batteries, even if they are too dead to operate the encoder, will keep the
clock running for a long time. When you do change your batteries, be sure to
put in the fresh ones within 30 seconds of removing the old ones, in order to
retain the date and time setting.
Question My batteries died a number of weeks ago, and they were removed for longer
than 30 seconds. How do I reset the time?
Answer Follow the directions above under Encoder Time Setting.
Question I recorded some sessions after the battery was removed for more than 30
seconds, so the encoder time may have been lost. What date and time will they
have?
Answer The date and time will be marked as invalid and will not be available for these
sessions. For each session recorded with an invalid time, the software will
prompt you for the starting time of the session. So if you know that the time is
invalid on the encoder, be sure to note the starting time of each session, if this
information is important.
ProComp Infiniti Hardware Manual 16

Compact Flash Usage
When a Compact Flash module is inserted in the unit (or the unit is turned on with a CF inserted)
and is recognized as a valid Compact Flash, the CF LED turns on for about 1 second, then blinks
in a single burst, a number of times to indicate available space. The CF LED then goes out,
awaiting a switch command. If no space remains on the Compact Flash, only the initial 1-second
blink is performed. This sequence is replayed when the dipswitch is changed.

If the card is not recognized as a valid Compact Flash, the CF LED blinks quickly (about 10 times
per second) for between 1 and 2 seconds, then blinks slowly a number of times indicating an
error code. The error code blink is repeated a total of 3 times. The CF LED then goes out.

ProComp Infiniti Hardware Manual 18

Attention: Do not remove the CF card without first stopping recording. If the CF card is removed during
recording, generally only the last second will be lost; however there is a small risk of greater data loss.
PROTECTED PINS
A number of regulatory bodies (like the FDA in the USA) have
adopted safety specifications requiring that all medical products for
physiological monitoring be manufactured with electrode leads that
have no exposed metal plugs. For this reason, the ProComp Infiniti
encoder and all our sensors use specially designed connectors that
have all metallic surfaces recessed within the plastic casing. These
connectors, with protected pins, require some care when plugging
and unplugging the sensors to the ProComp device or the extender
cable to the sensor head.
When connecting a sensor, be sure to properly line up the guiding
dot on the top of the plug with the notch in the encoder's input
socket. Forcing the plug into the jack in any other position may
damage your equipment.
Electrical Interference
When performing a biofeedback session, it is best to avoid placing the ProComp Infiniti
near the computer, display monitor or any other electrical device, where it can be
exposed to electromagnetic fields. We recommend that you try to keep the encoder within the
client's natural electrical field. In most cases, you can do so by fastening the belt-clip to the
client's waist.
Caring For The Fiber Optic Cable
A fiber optic (FO) cable is used for transmitting the
sensor data to the computer. Although this technology
provides maximal electrical isolation, signal fidelity and
freedom of movement, some care has to be taken
when handling the fiber optic cable, as it is much less
flexible than a regular electric wire.
Winding Or Bending
It is most important to avoid bending the cable too sharply. In a FO cable, information travels as
light impulses. Any kink along the optical fiber may partially or completely block the light's path
and, thus, interrupt the flow of sensor information to the computer. When using your system, try
to keep the extra length of cable wound in a loose loop no smaller than about 4 inches (10 cm)
in diameter.
Shorter Length Of Fiber Optic Cable
Although we ship the ProComp Infiniti system with one short and one long FO cable, the short
length should only be used as a troubleshooting tool because it is too short and forces the
ProComp Infiniti to stay too close to the computer. Should you suspect a problem with the long
FO cable, replace it with the short one and see if you can establish a good connection. If the
system works well with the short cable, then you probably have a break in the longer one.

searching for kinks. If you do find a break, the optic fibers may be too damaged to let the light
pass properly. Using a sharp, carpet cutter type blade, you can slice the FO cable into shorter,
unkinked bits. We do not recommend using scissors because they make a V-shaped cut that may
impede the data stream.
TT-USB And Encoder Connections
The FO connector on the ProComp Infiniti and the TT-
USB Interface are susceptible to breaking when they
are hit directly. This can occur if the ProComp Infiniti is
dropped on the floor. Whenever possible, fasten the
device to the client or to a chair, using the belt clip. On
the TT-USB Interface, you will also notice a hole
labeled Switch. This plug is for connecting external
devices, such as a muscle stimulation device, when you
want to use the switch control feedback option in the
software.
The TT-USB receives the data from the ProComp Infiniti encoder via the fiber optic and sends it
on to the computer via the USB port. It has four connectors;
1. Fiber Optic Connector – Connects to Fiber Optic Cable from encoder.
2. Mini USB Connector – Connects via USB cable to computer.
3. Switch Connector – Connects via a 3.5mm jack acts as a computer controlled switch.
4. Sync Connector – Connects to optional sync cable to connect more than one TT-USB
interface together to synchronize data between units. This input can also be used as an
event input.
