# Delsys Trigno EMG Setup

A Quick Start Guide for the Delsys Trigno EMG integration with Motive.

## Overview

Motive versions 3.4 and later support the digital integration of Delsys Trigno devices. Through this integration, Motive records electromyography (EMG) measurements from the Trigno EMG sensors along with the tracking data. 

This page provides instructions to set up the Delsys Trigno platform with the OptiTrack motion capture system.

### Required Components

The following hardware is required to use the Delsys Trigno EMG plugin with an OptiTrack Ethernet camera system:

* OptiTrack eSync 2 with BNC cable
* Delsys Trigno Centro
* Delsys Trigno Avanti, Mini, Duo or Quattro Sensors
* USB cable to connect the Delsys Trigno Base Station to Motive computer

The following software must be installed:

* Motive 3.4 or above, with a *Motive:Body* or *Body Unlimited* license
* Delsys Trigno Discover, with a license for 2.1 or above
* OptiTrack Delsys Plugin from the OptiTrack [downloads](https://www.optitrack.com/support/downloads) page. 

## Hardware Setup

The diagram below shows how the Delsys Trigno hardware connects to the Motive computer and the OptiTrack camera network. 

{% hint style="success" %}
Instructions on using the Delsys equipment are available in the [Delsys Trigno User Guide](https://delsys.com/downloads/USERSGUIDE/MAN-047-1-2-Trigno-Discover.pdf) or through [Delsys support](https://delsys.com/support/).

"><figcaption></figcaption></figure>

1. Connect the eSync 2 to the camera network. Please see the [External Device Sync Guide: eSync 2](/synchronization/synchronization-hardware/external-device-sync-guide-esync-2.md) page for instructions on this step.
2. Connect the Trigno BaseStation to the Motive PC with the USB cable.&#x20;
3. Connect the Trigno BaseStation to the eSync 2 with the BNC cable.
4. Open the *Trigno Discover* application.
5. Activate the Trigo Base Station and EMG sensor and connect them to Trigno Discover.&#x20;

## Software Setup

Install the required software and plugin on the Motive PC.&#x20;

### Delsys Software Setup

Follow the instructions for installing and using the Delsys *Trigno Discover* software found in the [Delsys Trigno User Guide](https://delsys.com/downloads/USERSGUIDE/MAN-047-1-2-Trigno-Discover.pdf) or through [Delsys support](https://delsys.com/support/).&#x20;

Open the *Centro Triggers* tab and enable the *Start Input* and *Stop Input* options. Select the channel the BNC cable is connected to on the Trigno Base Station (see below).

Once streaming is confirmed, close the Trigno Discovery application.

### Motive Setup

Download and install Motive from the [OptiTrack downloads](https://www.optitrack.com/support/downloads?cat=motive) site. Please see the [Installation and License Activation](/motive/installation-and-activation.md) page for more information about system specifications, licensing requirements, and installation instructions.&#x20;

{% hint style="success" %}
This plugin requires Motive version 3.4 or higher. Please [contact Sales](https://www.optitrack.com/contact) if you need assistance upgrading your Motive license.&#x20;
{% endhint %}

### Install Plugin

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.optitrack.com/movement-sciences/movement-sciences-hardware/delsys-emg-setup.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
