# Connect the 2nd PC

The 2nd PC is the brain of the setup. Any laptop, mini PC or desktop works — it does not need to be powerful.

## What you need

* The 2nd PC, already running Windows
* The USB cable that came with your DMA card

## Steps

1. **Plug the USB cable** into the port that sticks out of the DMA card at the back of the main PC.
2. **Plug the other end** into a USB port on the 2nd PC.
3. **Turn both PCs on.**
4. **Install the software** for your setup on the 2nd PC (the loader or tool that came with your order).
5. **Follow the on-screen steps** in that software. It will detect the card on its own.

## Two ways to use the 2nd PC

**Option A — second monitor or KVM** Keep the 2nd PC's screen next to your main monitor. Simple and reliable.

**Option B — fuser** A [fuser](/hardware/hardware-products.md) blends the 2nd PC's picture into your main monitor, so everything shows on one screen. Ask in your ticket and we will recommend one for your monitor.

## Common questions

**Can I use my old laptop?** Yes, as long as it has a free USB port and runs Windows 10 or 11.

**Does the 2nd PC need internet?** Only to download the software the first time. After that it can run offline.

**Can I use the same mouse and keyboard for both PCs?** Yes — that is exactly what the input device or fuser is for. Ask in your ticket and we will set you up.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://guides.privatesolution.org/dma-card-setup/connect-the-2nd-pc.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
