Overview
Update:
X680 is upgraded from V1.3 to V1.5 in June 2024, adding the following features:
- Supports switching between hosts in the web UI
- Supports HDMI input resolutions up to 1920x1080 at 60Hz
Notes
The X680 doesn't support PiKVM's Mass Storage Drive because it already supports hotkey switching. The integrated USB hub supports data sharing between 4 target hosts and can also be used for one of them, which will be available even in BIOS/UEFI when you need a live disk to revive the OS or even reinstall it.
Step-by-Step Guide: Reinstalling the Operating System Remotely
1. Insert a flash drive into a USB 2.0 port on your X680.
2. Utilize one of the target hosts to create a bootable USB stick using standard Microsoft tools, such as the Media Creation Tool. Alternatively, you can create a bootable USB stick from an ISO file using other tools like Rufus.
3. Switch to the target host where the operating system will be installed and proceed with the regular installation procedure.
This X680 is a member of the PiKVM[1] family, it is a 4-port IP KVM Switch empowers you to securely manage up to four computers/servers remotely from almost anywhere using the internet or your local area network (LAN).
Unlike software solutions that require installation and work through your server's operating system, this IP KVM Switch offers KVM control from the BIOS-level onward. Reboot, monitor the entire boot process, and interact with your connected system easily, while the integrated remote ATX power control allows you to switch the machine on/off, reset it, and monitor power & storage LED activity remotely. Featuring 3 additional USB2.0 ports for peripheral sharing (USB storage, CD ROM, etc.), allowing file transfers and disk emulation for remote application and OS installs.
The IP KVM Switch supports direct switching through buttons on front panel and hotkey through keyboard connected to the special USB 1.1 port. it also supports remote hotkey switching between computers for easy monitoring.
About the USB OTG port of X680: The USB OTG port is used to control the keyboard and mouse. However, when the OTG port is in use, it prevents the control of the keyboard and mouse. The X680 utilizes the CM4 and does not have additional USB ports for connecting a USB drive.

FAQ
- First of all, we recommend you to get more FAQ information on the official website: official FAQ, or check the following FAQ;
- You can post a issue ticket at Geekworm forum or email to us (support@geekworm.com) and attached your installation pictures or videos to get some help.
- Blog sharing for reference: https://www.andysblog.de/kvm-over-ip-pikvm-als-bausatz
Q: Why is the X680 not working?
A:
1. Firstly, must make sure the hardware expecially CM4 is connected correctly and securely.
- Check if the X680's onboard SYS-PWR, CM-PWR, CM-ACT LEDs are lit.
- If SYS-PWR LED is not lit, that means no power to X680; If the CM-PWR and CM-ACT LEDs are not lit, that means that the CM4 is not installed properly. Please recheck the CM4 installation, or check if the CM4 / X680 installation slot is damaged.(This is important! Many problems are caused by poor contact of CM4)
- If the X680's SYS-PWR, CM-PWR, CM-ACT LEDs are lit, then check the wiring connection.
Please refer to the following picture for the wiring connection and LED description.
2. Make sure to use the right pikvm OS. Only PiKVM V3 is supported.
V3 Pre-Assembled version already includes OLED display configuration, while V3 HAT Kit version need to configuring OLED yourself.
3. Important: Remove the USB cable after programming is complete.
4. Please email us at support@geekworm.com if you have further questions.
Q: Why is USB mass driver not recognized?
A: Please refer to the description in the red rectangle in the picture below;
The USB mass is not recognized in PIKVM OS, you can understand USB mass as a local USB HUB in PIKVM OS.
These 3 USB ports are used for local switching between target PC1-PC4, e.g. a USB disk with the OS image can be used to install the os in PC1, if switching to PC2, then the os can be installed in PC2, and so on.
Q: How to switch to root user?
A: run the following command:
su root
Then type the password, the default password is 'root' also.
Q: Does the x680 support audio?
Q: Why OLED is not display?
A: Please follow the steps below to check
1. Please confirm that your OS is right:
Due to downloading the wrong firmware, the OLED cannot be displayed. We ALSO made such mistakes during testing
2. Please check if the order of OLED screen pins is correct, please email to support@geekworm.com if it's a wrong pin order;
The run the following command to check the I2C address
sudo i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- 3c -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- --
3c is a hexadecimal number, it is the I2C address of OLED, if you can’t find this value, please shut down and reconnect shield and OLED, then run this command again, If you still can't find the OLED's I2C address, the OLED screen may be damaged.
4. Then run the following command to enable OLED display:
rw systemctl enable --now kvmd-oled ro
Q: Does x680 support proarammable switch between PC?
A: NO
Q: Does the X680 support PoE power? How to enable PoE Power?
A: The X680 doesn't support POE, but you can use something similar to the PD3005G-3A
Q: Why can't I switch to another PC?'
A: You need to make sure that your target computer is not in sleep, because when the computer is sleep, the USB port will stop supplying power
Q: Why NVME SSD cannot be recognized？
A: Login the pikvm web teminal, then type the following command:
lspci
The result of the command should look similar to the following, if you can't find something similar to the following, your NVME SSD is not compatible
