==User Manual==
First you need to make sure your hardware connections are correct, please refer to the above video and diagram below.
<span style="color:red;font-weight:bold">'''Important Note:'''</span> If you receive and are using the black 10pin I2S audio cable, the I2S cable maybe in the wrong wire connection. Refer to below photo.
Please do not use the wrong I2S cable for KVM-A8, you need to change the I2S cable to right direction to use or attach order number to contact us via email(support@geekworm.com).

===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 OS''', NOT support '''V4'''</span>

3. Flash it to a microSD memory card by following [https://docs.pikvm.org/flashing_os the simple instructions] or [https://www.raspberrypi.com/documentation/computers/getting-started.html#installing-the-operating-system Official installation tutorial]
4. Power the device, then open explore to login the pikvm web ui.
===Enable RTC ===
<span style="color:red;">Only need to configure the RTC function for the X630-A8 V1.7 version, X630-A8 V1.8 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''' button battery. run the following command in web terminal window:
1. switch to 'root' user
su root
then type the password, and the default password is 'root' also.
2. Switch OS to writable mode
rw
3. Edit the /boot/config.txt file, and change 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.txt
Then save & '''reboot''' the device;
4.Test & setting RTC, write&read the time of Raspberry Pi to RTC DS1307
date
sudo hwclock -w
sudo hwclock -r
5. Swith OS to readonly mode
ro
===Enable OLED display===
Run the following command in web terminal window to 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 hdmi audio===
Refer to [[Enable pikvm hdmi audio]]

Q1: Why PiKVM-A3/A4/A8 does not show the video only display No Signals?
</div>
<div class="mw-collapsible-content">
A:
# Please check the hardware connection. Double-check that the video capture device is connected correctly and tightly.
# Make sure you use the original HDMI port. If your desktop only has a VGA display port, there may be no video signal when you use <b>VGA to HDMI adapter</b>, 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.
# Change the HDMI cable to test.
# Test the X630 separately to check if there is HDMI output.
# Some laptops do not output any signal until you switch the output (usually via the FN + and an F5 key on the keyboard).
# Your computer maybe enter sleep mode, please exit sleep mode.
