* '''DON'T''' power via raspberry pi's TYPE-C port, because it is occupied as USB OTG.
* For use with raspberry pi 4, [[X630-A3]] (PiKVM-A3) equipped with a active cooling fan that cool your raspberry pi;
* For use with raspberry pi 4, [[X630-A8]] (PiKVM-A8 PCIe version) equipped with a active cooling fan that cool your raspberry pi;
* For use with raspberry pi zero 2 w, [[X630-A4]] (PiKVM-A4) allows to use [[C296]] aluminum heatsink with your raspberry pi zero 2 w, but user need to prepare 4pcs M2.5*7mm screws yourself.

'''Note:'''
:<span style="color:red;">Please use the supplied USB Type-C to USB 2.0 A-Male Cable only. USB-C to USB-A cable only with DATA lines(for keyboard and mouse emulation) and no power supply, Using other cable might cause instability or damage to either the host PC or the Pi.
:We need to ensure you isolate the 5v connection between the Raspberry Pi and host PC to prevent backpower issues that can cause instability or damage to either the host PC or the Pi.
:Some PC case may not have HDMI port, you need to use VGA/DVI to HDMI adapter to transfer HDMI port, but VGA to HDMI adapter may not be compatible with PiKVM-A3

#The black and red wires(wire group ②) come from X630-A5 accessories.
===OS Download & Installation===
1. Firstly, need prepair a micro sd card, a minimum 16 Gb class 10 memory card is recommended.
2. Download an appropriate OS image for the PiKVM, the url link is: https://pikvm.org/download/
:We recommend that you use the ''''V3 Pre-Assembled'''' version, and this image includes OLED display configuration.
:For Raspberry Pi 4, please use [https://files.pikvm.org/images/v3-hdmi-rpi4-box-latest.img.xz PiKVM V3 platform]. <span style="color:red;">Only compatible with '''PiKVM V3 Platform OS''', NOT support '''V4'''</span>
===OS downloadEnable RTC ===Download Link: https<span style="color:red;">Only need to configure the RTC function for the X630-A3 V1.5/V1.3/pikvmV1.org/download2 version, X630-A3 V1.6 don't need.</span>
1. switch to 'root'user su rootthen type the password, and the default password is 'PS:''root'also.
===Enable OLED display===
Run the following command in web terminal windowto enable OLED display:
rw
systemctl enable --now kvmd-oled
ro
If you are using <code>PiKVM OS V3 Pre-Assembled</code>, the OLED configuration is already pre-installed, you can ignore this step.
===Enable RTC hdmi audio===It is important Refer to note that we used a different RTC IC than the official PiKVM hardware. Firstly, insert the ```C1220``` button battery. run the following command in web terminal window:<pre>rwsudo nano /boot/config.txt#Then change the line: dtoverlay=i2c-rtc,pcf8563 to dtoverlay=i2c-rtc,ds1307 #Test RTC#Display the current time of the Raspberry Pidate #Write the time of Raspberry Pi to DS1307reboot before next stepsudo hwclock -w[[Enable pikvm hdmi audio]]

<summary>Q. Why the device does not show the video only display <b><span class="tb_red">No Signals</span></b>?</summary>
<ul><li>Please check the hardware connection. Double-check that the video capture device is connected correctly and tightly.</li>
<li>Make sure you use the <span class="tb_red">original HDMI</span> port. If your desktop only has a VGA display port, there may be no video signal when you use VGA to HDMI adapter, and there is no way to solve this; However, you can try to lower the resolution and restart the PC to test, but the probability of success is very low.</li>
<li>Change the HDMI cable to test.</li>
<li>Test the X630 separately to check if there is HDMI output.</li>
<li>Some laptops do not output any signal until you switch the output (usually via the FN + and an F5 key on the keyboard).</li>
<li>Your computer maybe enter sleep mode, please exit sleep mode</li>
