==Overview==
PiKVM-A8 is a member of the [[PiKVM]] <ref>PiKVM © belongs to https://pikvm.org</ref>family. It only supports Raspberry Pi 4 Model B. It is directly inserted into the computer case as a PCI card. That is, you can put a computer into your computer. It does not require additional cables and is more convenient to use.
==How to Cool==
[[X630-A8]] (PiKVM-A8 PCIe version) equipped with a active cooling fan (3007 5V PH2.0) that cool your raspberry pi;

==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). [[File:I2S-Cable-KVM-A8.jpg|400px|Right I2S Cable for KVM-A8]] ===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> :[[File:Pi4-V3-HAT.png|800px|PiKVM V3 platform]] 3. Flash it to a microSD memory card by following [https://docs.pikvm.org/downloadflashing_os the simple instructions] or [https://www.raspberrypi.com/documentation/computers/getting-started.html#installing-the-operating-system Official installation tutorial]
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 rootthen type the password, and the default password is 'root' also. 2. Switch OS to writable mode rw3. 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.txtThen 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 ==Installation Video=Enable OLED display===Run the following command in web terminal window to enable OLED display: rw systemctl enable --now kvmd-oled roIf you are using <code>PiKVMOS V3 Pre-A8 Installation Video: https:Assembled<//youtucode>, the OLED configuration is already pre-installed, you can ignore this step.be/BV8UkSgqWLo

'''Q: Why PiKVM-A3/A4/A8 does not show the video only display <span class="tb_red">No Signals</span>?'''
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.
3. Whether the raspberry pi 4 temperature is too high;
4. Maybe it is the problem of Pikvm OS itself, and needs Contact us via email to be resolved by PiKVMsupport@geekworm.com
A. No, one PiKVM-A8 can only control one pc. Please refer to [[X680]] 4-port IP KVM Switch.

#default password is root also
