For the HDMI-CSI bridge it depends on the version you bought. Either pull it gently up as on the Raspberry or push it sideways. Make sure that the cable is inserted on the correct side and until it stops, and then push the black latch back. Never connect or disconnect the flat cable from a powered device. This is not Plug-and-Play, and you can damage it. Also use only the cable that was included with the device package, or make sure that the third-party cable has the correct pinout.

**Raspberry Pi 4**: since one USB-C female connector is used to receive power and perform keyboard/mouse/drive emulation a special Y-cable must be made that splits the DATA and POWER lines of USB-C (see [reasons](https://github.com/pikvm/docs/issues/11)). It can be made from two suitable connecting cables, or soldered together from scratch. Be sure to check the circuit diagram below, otherwise you may damage your devices. The appropriate USB pinout(s) can easily be found on Google. Please note that if you make a Y-cable from two no-name cables, the colors of the wires may not match those shown. Use a multimeter to make sure the connections are correct.
**Raspberry Pi Zero W**: This board has two USB micro connectors: one for power supply, the second for emulating a USB OTG device. You need to prevent backpowering as in the RPi4 case. To do this, you need to cut off the red power wire in the OTG wire, or seal the +5v pin in the USB-A connector with electrical tape like this:
**Connect VIN pin of Arduino to [any Raspberry's 5v pin](https://pinout.xyz/pinout/5v_power) for PS/2 only device. But you don't need to connect the Arduino VIN pin if you connected USB (Arduino will get power through it).**

## SPI connection to Arduino Micro
Using an SPI connection, an Arduino Micro or compatible can be flashed from the Pi and used as an HID keyboard and mouse. Unlike UART, SPI does not share pins with Bluetooth on the Raspberry Pi so the Bluetooth radio does not need to be disabled.

Before powering either device, double-check the connections. The following should be wired from the Pi to either the level shifter or the Arduino. While the Arduino tolerates 3.3V logic input, 5V outputs from the Arduino can damage or destroy the Raspberry Pi and must not be connected directly to 3.3V GPIO pins directly.

Programming assumes the Arduino is powered via USB, either from the connected host or the Pi itself. If the USB is not connected, 5 V may be provided by the Raspberry Pi GPIO but should be disconnected prior to connecting USB to the microcontroller's USB port. The Raspberry Pi does not have backcurrent protection, a circuit using one or more Schottky diodes can be built to OR power from multiple sources but it's easier and more cost effective to avoid conflict and voltage differences between power supplies by leaving the 5 V wire disconnected.

If you need to change it, you will first need to connect to the switch with a Windows machine, most easily directly through an ethernet cord, with your Windows laptop (or VM) up and assigned to a fixed IP address, such as 192.168.1.5. Once you've launched the utility you will see this screen:

On this screen, ensure you are on the "General" tab. Click the radio button for "Network control". Change the IP address to the default for the switch (may already be this -- 192.168.1.10). Press the "Connect" button. Should make the status light go green, as well as the selected port. If you do not get a connection here, you cannot proceed to change the IP address. To change the IP address, change to the "Settings" tab at the top. You will then see this screen:

On this screen, change to your desired IP address, gateway, mask, and port. Then press apply. Watch the box on the right to see if it applied OK. Press Query again to double-check. The actual IP address will not be changed until you power off/power on the switch. Make sure you have these settings correct, because if you get them wrong you would have to connect over RS232/serial and not the network.

5. **Important!** If you are going to use GPIO pins to control a relay, KVM switch, or anything else, be sure to check the v3 shield pinout. Many ports are busy with internal functions. Before using them for your own use, you must disable them, otherwise you may damage the device.
3. _Optional:_ (This step is not nessessory if using TigerVNC) Some VNC clients (for example TightVNC) can't use user/password authentication. In this case you can enable passphrases mode in `/etc/kvmd/override.yaml`:
The `-o` makes sure that the WiFi passphrase is stored encrypted. Otherwise it will be stored in cleartext in the profile file. `wifi-menu` will scan for all available WiFi networks and provide you a list:
