Trigno Centro serves as the central hub of the Trigno System, connecting Avanti-Style Sensors and enabling high-quality EMG data collection. A high-throughput USB-C port ensures reliable, fast data transfer, while built-in features such as LED indicators, in-built triggering, synchronization outputs, analog channels, and event marking make Trigno Centro flexible and easy to integrate into a wide range of experimental setups. --- ## System Requirements | Material/Tool | Description | | --- | --- | | Software | Trigno Discover 1.7+ Delsys API 2.7.1+ | | Accessories | Power adapter, sensor charging station, USB-C cable | --- ## Step-by-Step Instructions ### Step 1: Powering and Connecting Trigno Centro 1. Connect Trigno Centro to power using the supplied adapter. 2. Connect the provided USB-C cable to the PC. > [!CAUTION] > Important > > - Only the Delsys provided SC-P09 Trigno medical power supply should be used. Do not use alternate power supplies. ![](https://cdn.us.document360.io/0adedc1d-5225-43a1-9673-53a5c8c15600/Images/Documentation/image(377).png) 1. When powered, the front LED on Trigno Centro turns white. ![](https://cdn.us.document360.io/0adedc1d-5225-43a1-9673-53a5c8c15600/Images/Documentation/image(87).png) 1. Press the power button on Trigno Centro to begin booting. 1. LEDs will flash orange during initialization. 2. Once booting is complete, LEDs turn solid orange, indicating the system is ready. ![](https://cdn.us.document360.io/0adedc1d-5225-43a1-9673-53a5c8c15600/Images/Documentation/image(88).png) --- ### Step 2: Understanding Trigno Centro LEDs Trigno Centro has two LED strips on the front panel that provide clear status feedback. | LED State | Meaning | | --- | --- | | No lights | No power connected | | White | Power connected, standby mode | | Flashing orange | Initializing (about 30 seconds) | | Solid orange | Ready to start streaming data | | Cyan | Pairing or Scanning command initiated (looking for Avanti-style sensors) | | Green Flashing | Data from the sensors are streaming to the device | | Magenta | Firmware update in progress (can take up to 30 minutes) | | Red | Internal error — Power Cycle the device | --- ### Step 3: Using Trigno Centro Features #### In-built Triggering Trigno Centro includes four BNC connectors on the back panel for sending or receiving trigger signals. These can be configured in Trigno Discover to use either a 3.3 V or 5.0 V TTL pulse, acting on rising or falling edges. - Any one of the four BNC connectors can be set as a start/stop trigger input. - Each connector also has a manual push button that can start or stop acquisition if the software command is not provided. ![](https://cdn.us.document360.io/0adedc1d-5225-43a1-9673-53a5c8c15600/Images/Documentation/image(89).png) #### Sync Outputs Trigno Centro provides a clock pulse synchronized with the Trigno wireless protocol (13.5 ms) via the BNC Connectors. In Trigno Discover, you can select output frequencies of 37, 74, or 148 Hz depending on your acquisition needs. This can be used to synchronize with other 3rd party systems that do not accept a TTL trigger pulse. ![](https://cdn.us.document360.io/0adedc1d-5225-43a1-9673-53a5c8c15600/Images/Documentation/image(90).png) #### In-built Analog Input The back panel of Trigno Centro allows integration of third-party analog sensors through a 15-pin female D-sub connection. The Trigno Analog Input Module can be connected to give easier access with 6 BNC connections. - Supports up to six analog input channels at an aggregate sampling rate of 48,000 samples per second - Configurable trigger channel available on pin 11, or on the Trigno Analog Input Module. - Four selectable input ranges from ±10 V to ±0.1 V, enabling optimization of signal-to-noise ratio For details on configuring analog inputs in Trigno Discover, see [Trigno Discover: Trial Set-Up](/v1/docs/trigno-discover-trial-setup). ![](https://cdn.us.document360.io/0adedc1d-5225-43a1-9673-53a5c8c15600/Images/Documentation/image(91).png) #### Microphone Input Trigno Centro also includes a 3.5 mm input jack on the back panel for connecting a PC-style condenser microphone. This input allows voice or sound to be sampled in a time-synchronized way with wireless sensor data. - Microphone signals are sampled at 48,000 samples per second with 24-bit resolution. - When the microphone input is active, the six analog input channels on the D-sub connector are suspended. > [!NOTE] > Information > > - If microphone inputs are enabled, then analog inputs cannot be used. > - Microphone data is recorded in Volts. ![](https://cdn.us.document360.io/0adedc1d-5225-43a1-9673-53a5c8c15600/Images/Documentation/base64-converted-image-1781024737800.png) --- ### Step 4: Key Features 1. Stream data from up to 32 sensors 2. High-throughput USB-C connectivity 3. LED status indicators for quick feedback 4. Flexible triggering via BNC connectors 5. Synchronized clock outputs 6. Integrated analog input with configurable ranges --- ## Troubleshooting | Issue | Solution | | --- | --- | | Trigno Centro displays solid red | Power Cycle the device. If the error persists, contact Delsys Support | | Trigno Centro flashes green but there is no software active | Power Cycle the device and reopen the software | --- DOC-659-1-0 The latest flagship Trigno system. Can stream data from up to 32 sensors, has built-in triggering capabilities, and has analog inputs. Our flagship wireless EMG product line; includes systems, sensors, and software. The newer models of our Trigno wireless sensors. These sensors are magnet-activated and have a flat, LED arrow. They are fully compatible with Trigno Discover, the Delsys API, and EMGworks. They are also compatible with all of our Trigno systems. Our flagship data acquisition software, compatible with all of our Trigno Systems and Avanti-Style sensors. The Delsys Application Program Interface (API) is designed as a bridge between Delsys Trigno data and the expanding digital world, creating customizable real-time interfaces for research and industry projects across movement and robotic applications. Pairing is a one-time setup that registers a sensor to a Trigno receiver Scanning is the process that detects sensors that have already been paired. Unplug your system from power and the USB connection for 3 seconds then plug back in. For Trigno Lite, simply disconnect from the PC then reconnect. - For clients from Europe, the Middle East & Africa, contact Delsys Europe Support - [support@delsyseurope.com](mailto:support@delsyseurope.com) - +44 161 504 5066 - For clients from the rest of the world, contact Delsys Support - [support@delsys.com](mailto:support@delsys.com) - +1 508 545 8200
