Power Supply
Trigno Systems are equipped with an isolated medical grade power
supply. The green power LED on the base station will illuminate
when power is connected to the Base Station. The power supply is
provided with interchangeable country-specific plug adapters. The
power supply can be conveniently stored in the Base Station storage
space when the system is not in use.
Figure 3. Trigno SC-P05 International Medical Power Supply with plug
adapter kit.
Trigno System are specifically designed and approved to
function only with the Power Supply provided. Power Supply
substitutions constitute a violation of the medical safety
approvals and will void the warranty.
If using a mains-powered PC then an additional isolation
transformer is required for medical compliance to IEC60601-1.
Refer to Appendix I for further details. No PC isolation is
required for operation on a battery-powered laptop.

13
Getting Started with the TrignoTM System
Software Installation
The Trigno EMG system is controlled by a PC through the USB
port, and thus requires specialized software. Trigno Systems
include a Delsys Software DVD containing EMGworks Signal
Acquisition and Analysis Software and the Trigno Control Utility
software for use with 3rd party data acquisition systems.
Install EMGworks from the Delsys Software DVD prior to
connecting the Trigno Base Station to the computer.
Powering the Base Station
Connect the Trigno power supply to the circular DC jack located
on the side of the Base Station. Energize the power supply by con-
necting it to a Mains outlet or to an isolation transformer. Ensure
that the PC to be used with the Base Station is connected to the
same isolation transformer. Please refer to Appendix I for clarifica-
tion on using an Isolation Transformer. The power LED on the
Base Station will illuminate anytime power is applied. Ensure that
the Base Station antenna is securely attached to the antenna con-
nector.
Figure 4. Connecting the Trigno Base Station power supply.
Connecting the Base Station
It is important to install EMGworks software prior to connecting
the Base Station to the PC. If not, the “Found New Hardware”
dialog will appear and Windows will prompt for a driver location.
Cancel this dialog and install EMGworks from the Delsys DVD in
order to register the Trigno drivers with the operating system.

14 Trigno Wireless System User’s Guide
TM
Once the software is correctly installed, the PC will automatically
detect the Trigno Base Station when connected to the USB port.
Charging the Sensors
Before using the system, the sensors should be fully charged by
placing them in the Base Station cradle slots. Ensure the Base Sta-
tion is powered and that the green power LED is illuminated.
When charging, the sensor LEDs will illuminate to an amber color.
Once the sensor battery is fully charged the sensor LED will turn
green. A complete charge cycle from a fully depleted sensor takes
approximately 2.5 hours.
Do not force the sensors into the recharging cradles of the Base
Station. The sensors are keyed so that they can only be inserted
in one orientation. Check the sensor orientation and check for
obstructions in the cradle if physical resistance is met while
cradling the sensors.
Recharge only with the approved power supply (SC-P05)
originally included with the system. Charging with any other
power supply may damage the device and will void the
warranty.

Acquiring Data in EMGworks Acquisition
Refer to the “Acquiring and Plotting Data” video tutorial
(provided on the DVD) for a brief introduction to configuring the
EMGworks software with the Trigno system. This and additional
EMGworks tutorials can be found on our website.
Refer to the EMGworks documentation (accessible in the Help
menu of the software) for detailed instructions on setting up data
collection in EMGworks.
Whenever data are collected in EMGworks, the analog outputs on
the base station are also active, so it is possible to collect data in
EMGworks and in a secondary data acquisition system
simultaneously.
Sampling the Analog Outputs
If samplig the analog output signals from the Trigno System using
a 3rd party data acquisition system, refer to the “Using the Analog
Outputs” section of this guide.
Digital Outputs (Trigno SDK)
The Trigno SDK presents digital outputs that can be read into sev-
eral common data collection platforms. Please refer to our online
help for more information.

Using the Wireless EMG Sensors
Orienting the EMG Sensors on the Skin
Trigno EMG Sensors employ 4 silver bar contacts for detecting the
EMG signal at the skin surface. It is crucial that the orientation of
these bars be perpendicular to the muscle fibers for maximum
signal detection. The top of the sensor is shaped with an arrow to
aid in the determination of this orientation. The arrow should be
placed parallel to the muscle fibers underneath the sensor. The
sensor should also be placed in the center of the muscle belly away
from tendons and the edge of the muscle. The sensor is easily
attached to the skin using the Delsys Adhesive Sensor Interface.
Figure 6. EMG Sensors must be properly oriented with the muscle fibers. Align
the sensor’s arrow with the direction of the underlying muscle fibers.
Cleaning the Sensor Site
Prior to affixing the EMG sensor on the surface of the skin, the
sensor site must be properly cleaned to remove dry dermis and any
skin oils. Wiping the skin prior to sensor application is critical. If
excessive hair is present, it will also be necessary to shave the site.
In cases where the skin is excessively dry, it may be useful to
dislodge dry skin cells by dabbing the site with medical tape. The
dry cells will attach the tape’s adhesive when it is removed. Be sure
to wipe with isopropyl alcohol to remove any adhesive residue that
may remain.
Applying the Trigno Adhesive Skin Interfaces
Trigno System are supplied with specially-designed adhesive
interfaces to simplify sensor attachment. These hypo-allergenic
interfaces are manufactured from medical grade adhesive approved
for dermatological applications. Usage of the interface promotes a
high quality electrical connection between the sensor bars and the
muscle-fiber direction

17
skin, minimizing motion artifacts and the ill-effects of line
interference. To ensure a strong bond with the skin, it is advised to
remove excessive hair and wipe the skin area and the EMG Sensor
with isopropyl alcohol to remove oils and surface residues. Allow
the skin to dry completely before applying the interfaces.
Adhesive Sensor Interfaces are for single use only.
Immediately discontinue use if skin irritation or discomfort
occurs. All Adhesive Sensor Interfaces and Reference Electrodes
are for single use only. Discard after using. Reseal storage bag
to maintain freshness.
Turning the Sensors ON
Trigno Sensors are turned on by depressing the rubber button for
approximately one second. The green LED on the sensor will
immediately begin to flash, and begin searching for a Base Station
that has been properly paired and is within its range. If no Base
Station is found, the LED will alternate between amber and green,
indicating that it does not have an established communication link.
As soon a link is established with the Base Station, the sensor LED
will flash green approximately once per second, indicating that data
are streaming.
Figure 7. Turning the Trigno Sensor “ON”.
Trigno Sensor Status Console
A Status console for Trigno Sensors is available when operating
EMGworks and when using the Trigno Control Utility. The
console tracks all Trigno sensors in the system in real-time, relaying
their on/off state, their battery charge level and their
communication quality in the network. Additionally, this console

18 Trigno Wireless System User’s Guide
TM
hosts the sensor pairing function and can send an “off” command
to all sensors.
A compact display of this information is accessible in EMGworks
by hovering over the notification area icon for the Trigno
hardware. The full dialog is displayed by double-slicking this icon.
Figure 8. The Trigno Sensor Status Console offers real-time sensor feedback.

power, E) wireless signal strength, F) sensor pairing, G) off command.
Turning the Sensors Off
There are several mechanisms for turning the Trigno sensors off,
described as follows:
•Send an “off” command via software
•Dock the sensor in an active charge cradle
•Hold sensor button for approximately 20 seconds
•5 minute time-out if sensor is not communicating with base
station

19
Using the Analog Outputs
The Trigno System provides simultaneous analog signal
reconstruction of data being detected by all active sensors. These
signals are made available on the 68-pin connectors located on the
Base Station. EMG signals at these outputs are amplified by a
factor of 909, with full dynamic range of ±5V. Similarly
accelerometer signals are presented with a nominal full range of
±5V. These must be calibrated according to their selected
operational range (±1.5g, ±6g). Note that the EMG and
accelerometer signals exhibit fixed 48 and 96ms delays respectively,
from the time the sensor detects the event to the time the analog
signal is reproduced.
