'''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

: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>

===Enable RTC ===
<span style="color:red;">Only need to configure the RTC function for the X630-A3 V1.5/V1.3/V1.2 version, X630-A3 V1.6 don't need.</span>
Due to different RTC chips with official PiKVM hardware, you still need to '''configure RTC''' to make RTC work normally.
Firstly, insert the ```C1220``` '''CR1220''' button battery. run the following command in web terminal window:<pre>1. switch to 'root' user su rootthen type the password, and the default password is 'root' also. 2. Switch OS to writable mode rwsudo nano 3. Edit the /boot/config.txt#Then file, and change the line: <code>dtoverlay=i2c-rtc,pcf8563 </code> to <code>dtoverlay=i2c-rtc,ds1307</code> (due to use the different RTC chip). sudo nano /boot/config.txtThen save & '''reboot''' the device;
===Enable OLED display===
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 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>
