Enterprise # Install a standalone Driver > Install the Synnax Driver on a computer other than the Core, log it in to the Core, and start it. Each Core includes the [Driver](https://docs.synnaxlabs.com/reference/hardware), which connects the devices on the Core’s computer. To connect devices on a different computer, install a standalone Driver on that computer. It connects to one Core over the network. ## Step 1Install the Driver **NI Linux Real-Time** Before you install: * Set the data acquisition modules of the controller to the NI-DAQmx real-time programming mode in NI MAX. See the [NI CompactRIO user manual](https://www.ni.com/docs/en-US/bundle/ni-compactrio/page/programming-modes.html). * Turn on SSH on the controller. You can turn it off after you install the Driver. Open an SSH connection to the controller and log in as `admin`. On NI Linux Real-Time, `admin` is root, so the commands on this page need no `sudo` there. Run: ```bash curl -LO https://github.com/synnaxlabs/synnax/releases/download/driver/v0.60.0/install-driver-nilinuxrt.sh && chmod +x install-driver-nilinuxrt.sh && ./install-driver-nilinuxrt.sh ``` The script installs the Driver as a service and starts it. The service also starts each time the controller starts. The Driver runs as root. **Linux** > The Driver needs a recent glibc. See [Requirements](https://docs.synnaxlabs.com/reference/enterprise/requirements) for the supported Linux versions. Download the Driver: ```bash curl -LO https://github.com/synnaxlabs/synnax/releases/download/driver/v0.60.0/synnax-driver-v0.60.0-linux ``` Move it into a folder on your `PATH`, and make it executable: ```bash sudo mv synnax-driver-v0.60.0-linux /usr/local/bin/synnax-driver ``` ```bash sudo chmod +x /usr/local/bin/synnax-driver ``` Install the systemd service: ```bash sudo synnax-driver install ``` The `install` command creates a `synnax` system user, the empty environment file `/etc/synnax/driver.env`, and the `synnax-driver` service. It does not start the service. It gives the service real-time permission and writes the udev rule `/etc/udev/rules.d/99-synnax-driver-latency.rules`, so Arc automations can run with [precise timing](https://docs.synnaxlabs.com/reference/control/arc/timing?platform=Linux#get-the-best-timing-from-a-computer). For [EtherCAT](https://docs.synnaxlabs.com/reference/hardware/ethercat/configure-device#network-interface-access), it gives the service raw Ethernet access and writes the udev rule `/etc/udev/rules.d/99-synnax-driver-ethercat.rules`. After you upgrade the Driver, run `sudo synnax-driver install` again. **Windows** Download the Driver: ```powershell Invoke-WebRequest -Uri "https://github.com/synnaxlabs/synnax/releases/download/driver/v0.60.0/synnax-driver-v0.60.0-windows.exe" -OutFile "synnax-driver.exe" ``` Move `synnax-driver.exe` to a permanent folder, such as `C:\Program Files\Synnax\`. Then add that folder to the `Path` system environment variable, so that each terminal can run `synnax-driver`. Then open a new terminal. **macOS** Download the Driver: ```bash curl -LO https://github.com/synnaxlabs/synnax/releases/download/driver/v0.60.0/synnax-driver-v0.60.0-macos ``` Move it into a folder on your `PATH`, and make it executable: ```bash sudo mv synnax-driver-v0.60.0-macos /usr/local/bin/synnax-driver ``` ```bash sudo chmod +x /usr/local/bin/synnax-driver ``` Check the installation: ```bash synnax-driver version ``` The output ends with the version: ```text Synnax Driver v0.60.0 ``` ## Step 2Log in to the Core Create a user for the Driver with the [Host role](https://docs.synnaxlabs.com/reference/enterprise/users#roles). Then run `login`. On Linux, run it with `sudo`. On NI Linux Real-Time, run it as `admin` with no `sudo`: ```bash sudo synnax-driver login ``` The command asks for the address of the Core, and checks that it can reach the Core. Then it asks for the username and the password: ```plaintext Host [localhost]: 10.0.0.45 Port [9090]: Secure (Y/N) [N]: Username: driver Password: ``` When the output shows `credentials saved successfully!`, the Driver is logged in. > The Driver saves the password as plain text in its state file, and each user of the computer can read the file. Give the Driver a user with only the Host role, not an administrator. ### Log in to a Core that uses TLS Answer `Y` to `Secure` when the Core uses TLS, and give the host name of the certificate, not an IP address. A certificate from a public authority, such as Let’s Encrypt, needs no more setup. For a certificate from your own authority, or from a Core that runs with `--auto-cert`: * **Linux, NI Linux Real-Time, and Windows** -> add the CA certificate to the trust store of the operating system. See [Install certificates](https://docs.synnaxlabs.com/reference/enterprise/certificates). * **macOS** -> the Driver does not read the macOS keychain. See the macOS tab of [Install the certificate](https://docs.synnaxlabs.com/reference/enterprise/certificates?platform=macOS#install-the-certificate). Set `GRPC_DEFAULT_SSL_ROOTS_FILE_PATH` in the shell that runs `login` and `start`. On Linux and NI Linux Real-Time, you can instead set the same variable in `/etc/synnax/driver.env`, before you run `login`. See [Environment file](https://docs.synnaxlabs.com/reference/enterprise/driver/configuration#environment-file). The Driver then trusts only the certificates in that file. ## Step 3Start the Driver **NI Linux Real-Time** The Driver started before you logged in, so restart it: ```bash synnax-driver restart ``` **Linux** Set the service to start when the computer starts, then start it: ```bash sudo systemctl enable synnax-driver sudo synnax-driver start ``` **Windows** The Driver has no service on Windows. Run it in a terminal, and keep the terminal open: ```powershell synnax-driver start --standalone ``` **macOS** The Driver has no service on macOS. Run it in a terminal, and keep the terminal open: ```bash synnax-driver start --standalone ``` ## Step 4Check the Driver **NI Linux Real-Time** Check the service: ```bash synnax-driver status ``` A running Driver prints: ```plaintext Synnax Driver is running (PID: 28191) ``` **Linux** Check the service: ```bash synnax-driver status ``` **Windows** The terminal that runs the Driver shows its logs. **macOS** The terminal that runs the Driver shows its logs. The Driver shows in the devices toolbar under the host name of its computer. To connect devices to it, see [Devices](https://docs.synnaxlabs.com/reference/hardware/devices).
