# How can I synchronize PRO/PRO X devices with other systems?

We support four communication protocols:

1\. Lab Streaming Layer (LSL), which is a wireless protocol.

2\. UDP (wireless protocol) TTL wired triggering.

3\. 1-bit TTL triggering is supported by PRO and PROX, and an 8-bit TTL connector can be found only on PROX. You can find an example blog on how to send triggers using a TTL cable [linked here](https://mbraintrain.com/how-to-set-up-ttl-in-neurobs-presentation-with-smarting-pro/).

4\. UTC timing *(contact us for more information)*

You can send triggers/data streams from any software/hardware that support these protocols. If you need help with designing your experiment, you can contact us at [support@mbraintrain.com](mailto:support@mbraintrain.com)

We can share example scripts written in:

- **MATLAB, using Psychtoolbox functions**. We have scripts that send LSL and UDP triggers. As an example task, we used Checkerboard (visual) and Three-tone Oddball task (auditory).
- **Python + PsychoPy**. Same as with previous.
- [**Neurobs Presentation software**](https://www.neurobs.com/) support LSL and TTL communication. We also have sample visual and auditory experiments.
- [**E-Prime**](https://pstnet.com/products/e-prime/) software can use all LSL, TTL and UDP protocols. If you're not using any of these but need help figuring out the synchronization, feel free to reach out.
