BIONOMADIX BN-ACCL3 MODULE
BioNomadix Accelerometry X, Y, Z — Wireless Physiology
The BioNomadix Tri-axial Accelerometer (BN-ACCL3) is a broad spectrum acceleration measurement
system. The transmitter can be attached to any part of the subject's body to measure three-axis acceleration
associated with movement in that particular location.
The system comes factory preset to support an operational range of ±16 G, with a maximum system
bandwidth of 400 Hz. Ranges can be set to as low as ±2 G with bandwidths as low as 3 Hz.
The system can also be configured to act as a "tap detector," detect either single or double taps. In this
mode, the system can act as an event recorder for self-report. When "double-tapped," for example, the
system will output a pulse to precisely mark the time location of the observed event.
In Acceleration measurement mode, the BN-ACCL3 will output X, Y and Z acceleration values on three
associated channels. The system is very well suited for mobile applications. The system can measure the
acceleration of gravity (static) for tilt-sensing and can also measure very fast-changing, dynamic
acceleration resulting from rapid movement or impact.
The BioNomadix Accelerometer module is capable of recording three independent X, Y and Z channels.

Setup Overview
1. Setup the BioNomadix ACCL3 Transmitter (BN-TX) with subject.
2. Setup the BioNomadix ACCL3 Receiver (BN-RX).
3. Setup the software.
Hardware Setup
The BioNomadix ACCL3 Transmitter and Receiver unit are shipped as a matched pair and must always be
used as a pair (see serial number and ID sync options). Up to 16 channels per BioNomadix system can be
monitored simultaneously, returning data quality equal to standard BIOPAC MP modules. Normal
operating range between transmitter and receiver is 10 meters line of sight in standard laboratory
environments.
BioNomadix Transmitter
Setup
1. Secure the Transmitter module on Subject, (i.e. with a strap, or
inside a BioNomadix shirt pocket).
For optimum results, the BioNomadix Custom Sport Shirt is
recommended. This specially-designed shirt is made of a
lightweight material with numerous “pockets” for housing
multiple transmitters.
2. Set the power switch on the BioNomadix Transmitter to ON. The Status light will flash sequences
based upon connectivity and battery life. Single blinks every half second indicates that the
transmitter and receiver are not communicating.
3. Double blinks occurring every two seconds indicate successful pairing and normal operation
between transmitter and receiver.
Controls
ID: Press to illuminate Status light of matching Receiver unit.
On/Off: Power switch for the transmitter. The transmitter power must be turned OFF for charging.
Status: Solid amber when battery power is low. Approximately one hour of operation remains after
light turns amber, full-charge with BN-BAT-CGR battery charger typically requires one hour.
BioNomadix Receiver
BEFORE BEGINNING:
Decide whether one or both available channels will be used. (If using only one channel, set “X”
to ON and “Y” and “Z” to OFF)
Set channel slider to correct position.
Attach Receiver unit to the right side of the MP150 unit, or the left side of the IPS100C. The
Status light will turn green when communicating with transmitter.
Set desired channel options on the Receiver module.

second when communication is interrupted.
Input Signals: X, Y & Z
“X” Assigns the input signals for channels 1-4.
“Y” Assigns the input signals for channels 5-8
“Z” Assigns the input signals for channels 9-12.
On/Off
Enables or disables module channels: “X” channels 1-4, “Y” channels 5-8, Z
channels 9-12.
Transmitter Battery Life
Transmitter battery life is described below as a change of color in the sequence of LED flashes.
LED Color Pattern Charge %
green green green green 75% - 100%
yellow green green green 50% - 75%
yellow yellow green green 25% - 50%
yellow yellow yellow green 5% - 25%
yellow yellow yellow yellow < 5%
System Setup
Connect the BioNomadix Receiver to the right side of the MP150, and then turn on the MP150 power
button. Data acquisition to MP150 will proceed as programmed.
Transmitter Characteristics
If the paired signal is interrupted due to electrical interference or a subject wandering out of range, the most
recently-acquired data point to the MP150 will be retained, with normal wireless transmission continuing
once communication is reestablished. See BioNomadix Operational Range and Characteristics on page 6.

BioNomadix Operational Range and Characteristics
10 meters line-of-sight is typical in standard laboratory environments. Operational range can be more or less
depending on factors such as presence of electromagnetic interference, multi-path, or RF signal blocking. In the event
of a communications failure, BioNomadix modules will attempt to re-establish communication over a one second
period and during this time, the data will be kept at the last successfully transmitted value. After 0.5 second of
communication failure, the BioNomadix transmitter will return the data to a “0” value and will continue to attempt to
re-establish communication with the paired receiver.
The BioNomadix transmitter is purposely kept at very low power so as not to disrupt the sensitive biophysical
parameter measured and to enhance battery life. If the BioNomadix pair is used outside the laboratory (used without
the benefit of multi-path) and if the Transmitter is line-of-sight blocked from the Receiver, then communication
dropouts are increasingly possible. A functional solution is to keep the Transmitter and Receiver in constant line-of-
site view.
