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 non­invasive 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.

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
the Pro-SB in place of the TT-USB as described in the BioGraph

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

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).
