Fixed HDMI back power issue. USB-PC The BLIKVM PCIe card provides two USB interfaces, one is PC-IN (type c interface) and the other is USB-PC2 (pin interface). The purpose of these two interfaces is to connect to the USB of the controlled computer, used to control the mouse and keyboard. At the same time, only one interface can be used. The purpose of designing two interfaces is to directly use USB PC2 when the user's PC host has a row pin USB interface, which will make the wiring more concise. POWER-IN When using PoE power supply, there is no need to connect the PWR-IN port. When not using PoE power supply, connect the PWR-IN port to a standard 5V/3A USB power supply. ETHERNET-PoE Gigabit Ethernet port Standard: IEEE 802.3af PoE Input voltage: 37-57 V DC Output power: 5 V DC/2.4 A ATX-Connecter Connect to power control interface on the motherboard of the controlled computer with DuPont cables. It can turn on, off, and restart the controlled computer. The pin is defined on the printing of the PCIe board, BTN means button. According to the instructions of the computer motherboard, first find the position of the ATX function related pins on the motherboard, and then unplug the ATX ray that has been connected to the motherboard. After unplugging, the power button of the computer will lose its function. There are two rows of 8PIN pins on the PCIe board. It is unnecessary to distinguish between the two rows of pins when they are used with the same functions. One row of pins is used for KVM to control ATX-related functions, and the other row of pins is connected to the ATX DuPont head unplugged from the main board to maintain the original chassis power button function. Connect each wire according to the specific pin definitions on the motherboard and PCIe.

The default baud rate is 115200. There is an onboard CH341-based USB to UART converter present inside BliKVM v4 which is connected to UART0 of the mCore-H616 SoC , so you can connect a USB port of a PC to the 5V port without an external UART and a USB-C to dupont adapter. PC USB port current output Be careful when trying to use the 5V port because a PC USB port alone may not be able to provide 3A (5V) which is a documented requirement for the board to work. Either use a 12V 2A DC port at the same time as using the 5V port for serial communication without a USB Splitter board, or use the splitter board to split out the VCC pin and use a separate 5V 3A power supply to provide power to the 5V port's VCC pin. Likewise, when disconnecting a cable from the 12V 2A DC port while BliKVM is powered on, make sure to disconnect the cable from the 5V port first (because that will become the power source for BliKVM v4 after the 12V 2A source is disconnected unless a splitter is used). You should see something like this in your host kernel log (if you are using a Linux-based OS) when attaching a USB cable to the 5V port of BliKVM v4: usb 1-1.2: new full-speed USB device number 12 using xhci_hcd usb 1-1.2: New USB device found, idVendor=1a86, idProduct=7523, bcdDevice=81.34 usb 1-1.2: New USB device strings: Mfr=0, Product=2, SerialNumber=0 usb 1-1.2: Product: USB Serial ch341 1-1.2:1.0: ch341-uart converter detected usb 1-1.2: ch341-uart converter now attached to ttyUSB0 Accessing this port can then be done using GNU screen or TIO : tio /dev/ttyUSB0 mangopimcore login: blikvm # ...

Either use a 12V 2A DC port at the same time as using the 5V port for serial communication without a USB Splitter board, or use the splitter board to split out the VCC pin and use a separate 5V 3A power supply to provide power to the 5V port's VCC pin. Likewise, when disconnecting a cable from the 12V 2A DC port while BliKVM is powered on, make sure to disconnect the cable from the 5V port first (because that will become the power source for BliKVM v4 after the 12V 2A source is disconnected unless a splitter is used). You should see something like this in your host kernel log (if you are using a Linux-based OS) when attaching a USB cable to the 5V port of BliKVM v4: usb 1-1.2: new full-speed USB device number 12 using xhci_hcd usb 1-1.2: New USB device found, idVendor=1a86, idProduct=7523, bcdDevice=81.34 usb 1-1.2: New USB device strings: Mfr=0, Product=2, SerialNumber=0 usb 1-1.2: Product: USB Serial ch341 1-1.2:1.0: ch341-uart converter detected usb 1-1.2: ch341-uart converter now attached to ttyUSB0 Accessing this port can then be done using GNU screen or TIO : tio /dev/ttyUSB0 mangopimcore login: blikvm # ... If you need to check how much data is received over UART0 you can do this by looking at the counters exposed via proc as follows (the rx counter should increase when the data is sent from an external host if the built-in USB to UART converter is working properly): root@mangopimcore:~# grep '0: uart' /proc/tty/driver/serial 0: uart:16550A mmio:0x05000000 irq:284 tx:20306 rx:40 pe:1 RTS|DTR","title":"Serial Console Access via the 5V Port"},{"location":"BliKVM-v4-guide/#dev","text":"If you want to develop or port software on v4 hardware yourself, you can refer to this hardware resource description .","title":"Dev"},{"location":"BliKVM-v4-guide/#buy-link","text":"Buy v4","title":"Buy link"},{"location":"Datasheet-BliKVM-v4/","text":"BliKVM v4 Allwinner (H616/H313 SOC) BliKVM is a production-ready, plug and play KVM-over-IP device that offers professional users a convenient solution for remote server or workstation management .

B-board The b-board has an adapted full-height and half-height metal PCI mounting plate, which can be installed on the computer case. The user connects the pins on the B-board to the ATX control interface on the computer motherboard using the color DuPont cables provided with the product. ATXA-B Instructions for connecting to the computer motherboard According to the instructions of the computer motherboard, first find the position of the ATX function related pins on the motherboard, and then unplug the ATX ray that has been connected to the motherboard. After unplugging, the power button of the computer will lose its function. There are two rows of 8PIN pins on the ATXA-B motherboard. It is unnecessary to distinguish between the two rows of pins when they are used with the same functions. One row of pins is used for KVM to control ATX-related functions, and the other row of pins is connected to the ATX DuPont head unplugged from the main board to maintain the original chassis power button function.

For example, if the EDID is set to 1080P60Hz, and the controlled computer supports this resolution, it will output at 1080P60Hz. Additionally, EDID can be used to disable audio, modify the display model, name, manufacturer, and other information. In most cases, you don't need to change it, but sometimes, especially with strange UEFI/BIOS behavior, it may be necessary. Note BliKVM v1, v2, and v3 use the CSI video capture scheme, which supports EDID settings. However, BliKVM v4 uses the USB video capture scheme, which does not support EDID settings. For v3 HAT, there is a limitation of two CSI channels on the Raspberry Pi 4B, which means it can only capture video input with a maximum resolution of 1080P50Hz. Therefore, if you set 1080P60Hz EDID for v3, it will not be able to capture the image. If you are using PiKVM OS, you can refer to this link for modification instructions.

Both editors work with the binary EDID format. Using these tools, you can modify the EDID information like editing a file, similar to changing the information on an identity card. By editing the EDID, you can adjust the parameters and characteristics of the display to suit different usage requirements, and thus achieve better display performance.","title":"HDMI EDID"},{"location":"edid/#edid","text":"The EDID file in BliKVM serves the purpose of informing the controlled computer about the expected HDMI output resolution.

By editing the EDID, you can adjust the parameters and characteristics of the display to suit different usage requirements, and thus achieve better display performance.","title":"Custom EDID"},{"location":"faq/","text":"FAQ & Troubleshooting As a first step, we recommend carefully reading our documentation. Most steps to successfully set up your BLIKVM are already described there. If you run into any issues you can check this page which will list common errors. If that still doesn't help you you're welcome to raise an issue ticket or join our Discord for further help. Common Questions Can I connect multiple servers to a single BLIKVM? Yes, but it requires additional work to set up. See this page . How can I get the access to PiKVM in my local network over Internet? If your router has an external IP address, you can use port forwarding to forward port 80 (Web), port 8008 (mjpeg), and port 8188 (webrtc) In all other cases, you can use the excellent free VPN service Tailscale. Which BLiKVM hardware version should I choose, such as BLiKVM V1 CM4, BLiKVM V2 PCIe, and BLiKVM V3 Hat? First, please refer to this page for a comparison of the main parameters of each version. V1 and V3 are external solutions, while V2 is an internal chassis solution. If you have a chassis and there is space inside, choosing the V2 PCIe version would be a better option. So how do you choose between the external solutions V1 and V3? V1 is based on the CM4 platform, with higher integration and ready-to-use versions available. V3 is based on the Raspberry Pi 4B platform, with all IO ports exposed and greater expandability. Another key difference is that V1 supports up to 1080P60Hz input, while V3 supports up to 1080P50Hz input. Of course, you also need to consider whether you already have a CM4 or 4B, as purchasing the corresponding baseboard would offer better cost-effectiveness. Can I use BLIKVM for gaming? No, because: For HDMI-CSI bridge, bus bandwidth is not enough to transmit more than 1080p60. For HDMI-USB dongle, high latency and low video quality. General hardware video capture differs from software streaming and introduces additional latency. Can BLIKVM do 4K video? For HDMI-CSI bridge, no. There is not enough bandwidth in the CSI bus for that much data. 1080p60 will max out the bandwidth. For the USB capture devices: technically yes, they will downsample to something smaller to meet the USB 2.0 bandwidth limitations, so the source may be 4k, but the stream will not. The 4K real-time video will not fit through the network anyway. Where does the cursor/video latency come from? Here is the chain of transferring an image to your browser or VNC client. Capture device -> Compression -> Network -> Decompression -> Rendering 100-200ms is very, very fast for this. But we are working to speed things up even more. Does BLIKVM support sound? BliKVM v1 CM4, v2 PCIe, v3 HAT version supported\uff0c v4 Allwinner not support now. Can I power the Pi via PoE? Yes! Hat and PCIe version supported. First Steps What is the default password? How do I change it? If you use PiKVM, there are two types of accounts: OS and PiKVM (web interface) accounts. The system account blikvm can be used for SSH/UART access and has the password blikvm . The web interface account is called admin and has the password admin . The PiKVM account cannot be used for SSH access and vice versa. To change passwords, use the following commands (become the root user): su - # If you're in the webterm rw # Switch filesystem to read-write mode passwd blikvm # Change blikvm user password kvmd-htpasswd set admin # Change web ui admin password ro # Back to read-only How do I add another user? If you use PiKVM software, as stated above you need to make 2 accounts, 1 for the shell, the other for the PiKVM Web UI. If you require additional users for PiKVM UI, you can use the following: # su - # rw # kvmd-htpasswd set发货清单
