   ‡ When connecting to your device by SSH, it can be addressed in three different ways:

   1. Using DNS
   2. Using mDNS
   3. Using its IP address directly

   In most organisations, central DNS servers are used. If your device is using a 'static' IP configuration, your IT department will have to create a DNS entry for it manually. If your device is using a dynamic (DHCP) IP configuration, the DNS entry will often be created automatically. To SSH into your device using DNS, set the hostname in your client to the device's hostname, e.g. MC-112345.

   If DNS is not provided by your organisation or your broadband router, try using mDNS. When your device is connected to a network, it announces its presence to all other nearby devices such as your laptop or PC. If your laptop or PC is configured to recognise these announcements, you can SSH into your device using mDNS by setting the hostname in your client to the device's hostname followed by ".local", e.g. MC-112345.local.

   If the above methods are not successful, use the devices IP address directly. The MinKNOW UI shows the IP addresses for each interface in the Settings - Network page. If your device has LAN and Wi-Fi interfaces, each will have a different IP address. To SSH into your device using its IP address, set the hostname in your client to the IP address, e.g. 10.20.30.41.

9. To connect the MinION Mk1C router to a Linux device:
   1. Locate the MinION Mk1C ID on the underside label of the device:

   

   1. Click on the Wi-Fi icon on the right of Menu bar at the top of the screen.

   

   Identify and click on the MC-XXXXXX ID under the Wi-Fi network options icon (shown above). Enter the Wi-Fi password (shown below) in the pop-up Wi-Fi Network Authentication window:

   Login with the Password:
   WarmButterflyWings98

   

   The following window will be presented when you have connected to the MinION Mk1C Wi-Fi router.

   

   1. Access the MinION Mk1C using the Linux File Browser and enter the server address.

   Open the File Browser (this can be found using the Search tool). Select Connect to server on the bottom of the list in the left panel. You will need to enter:

2. Network configuration - connection to your MinION Mk1C

   The MinION Mk1C has two interfaces that we support for data transfer. These are:

   • Ethernet port - direct to interface or LAN
   • Wi-Fi - direct to interface

   

   Networking with MinION Mk1C. Blue lines indicate a connection via the internet. The black line indicates a wired connection. The computer on the LAN (B.) can be used to configure the device using parameters that are not available through the Admin interface. You can also configure the MinION Mk1C using the Wi-Fi connected device (A.), however network compatibility issues may inhibit the update.

   Internet connection:

   This configuration requires an ethernet connection to the Local Area Network (LAN) from the MinION Mk1C. The LAN is connected to the internet, which enables updating of MinKNOW on the device.

   Interface connection:

   An interface, such as a laptop/mobile device/computer, can be wirelessly connected to the MinION Mk1C. Alternatively, the MinION Mk1C may be accessed and controlled by a computer on the LAN.

   Other configurations are also possible, however they are not supported by Oxford Nanopore Technologies:

   • Ethernet-desktop/laptop computer to control the MinION Mk1C - no internet
   • MinION Mk1C Wi-Fi (Client) to a router and desktop/laptop Wi-Fi to a router, which is itself connected to the internet
   • It is possible to adapt other data connections through the USB 2.0 port, however, Oxford Nanopore Technologies cannot advise or support this use.
3. Connecting by SSH/the terminal provides options to configure and access your MinION Mk1C computer and network.

   Connecting by the command line via SSH or the terminal enables several options:

   • Access and transfer data on to a mounted USB-hard drive - for instructions, see the Data transfer via SFTP section of this user manual.
   • Change the output directory from /data
   • Change between static and DHCP (dynamic) IP address of the ports on the MinION Mk1C
   • Access to the logs
4. Windows
5. Option 1

   If SSH is enabled in your Windows build, you can use the built-in Windows Command Prompt (CMD). Open a CMD prompt, then enter ssh minit@hostname (e.g. ssh minit@mc-111414):

   

   If it is your first time connecting, you will be asked to confirm the authenticity of the host. Enter yes to continue:

   

   Enter the password to establish an SSH connection. The default password is minit. Please note that characters will not appear on-screen as you type in the password.

   

   If the SSH connection is successfully established, the shell prompt will now read minit@hostname:~$

   

6. Option 2

   A third-party SSH client such as Bitvise (example images shown below) or Putty may be used. The following default options can be entered:

   Host – device ID or IP address (e.g. MC-111414)
   Port – 22
   Username – minit
   Initial method – password
   Password – minit

   

   If a connection is successfully established, Bitvise will automatically open a terminal window and an SFTP browser. Alternatively, you can click on New terminal console or New SFTP window on the left-hand side:

   

7. Linux/macOS
8. On both Linux and macOS operating systems, you can use the built-in Terminal program.

   Open a Terminal, then type ssh minit@hostname (e.g. ssh minit@mc-111414):

   

   If it is your first time connecting, you will be asked to confirm the authenticity of the host. Enter yes to continue:

   

   Enter the password to establish an SSH connection. The default password is minit. Please note that characters will not appear on-screen as you type in the password.

   

   If the SSH connection is successfully established, the shell prompt will now read minit@hostname:~$

   

1. Important If you are uncertain about changing any network parameters on your device, you will need to contact your IT department.
2. Network configuration - Static vs dynamic IP

   The LAN interface on the MinION Mk1C can operate in either DHCP (dynamic) mode or static mode. When in DHCP mode, the settings are acquired from the network’s DHCP server. Some networks do not have a DHCP server or you may wish to override the settings it provides. In such circumstances, the static mode can be used.

   The static mode comes pre-configured with the following settings:

   
IP Address/Subnet Mask: 192.168.0.1/24
Default Gateway: 192.168.0.1
DNS Servers: 9.9.9.9, 8.8.8.8


3. To configure static IP addressing on the Ethernet port:

   Here is an example of possible static settings that may be provided by your IT department:

   
IP Address: 10.20.30.40
Subnet Mask: 255.255.255.128
Default Gateway: 10.20.30.1
DNS Servers: 10.0.0.53, 10.0.1.53

   
   
   To change the static profile to match these settings:

   1. Log in to your MinION Mk1C using SSH via the WiFi connection.
   2. If you are given the subnet mask in the form xxx.xxx.xxx.xxx, convert this to CIDR format, which is a number between 1 and 32 (common values are 16, 24 and 25). You can use the following website to convert from xxx.xxx.xxx.xxx to a CIDR value: https://docs.netgate.com/pfsense/en/latest/network/cidr.html
   3. Look up the xxx.xxx.xxx.xxx value in the first column and find the corresponding CIDR value in the second column. In the example above, 255.255.255.128 corresponds to a CIDR value of /25.
   4. Once you have this value, open a terminal window and enter the following commands:
      
      

   sudo nmcli con down dhcp

   sudo nmcli con down static

   sudo nmcli con mod static ipv4.method manual ipv4.address 10.20.30.40/25 ipv4.gateway 10.20.30.1 ipv4.dns 10.0.0.53,10.0.1.53 ipv4.routes "" connection.autoconnect yes

   sudo nmcli con up static

   In some instances, these commands may give an error message, however this is not a problem and the error should be ignored.
   The addresses specified in the third command line are the values that need to be changed to match particular settings. Note that there is no space between the DNS server addresses.

   Use the following command to verify that your settings are correctly applied:

   
sudo nmcli dev show eth0


4. To configure dynamic IP addressing on the Ethernet port:

   Open a terminal window and enter the following commands:

   
sudo nmcli con down static
sudo nmcli con up dhcp


1. Important Hardware check

   A hardware check must be performed on all new devices or when software has been updated. This uses the Configuration Test Cell(s) (CTC), that come pre-inserted into your device in place of flow cells.

   Note: If using a Flongle Flow Cell, we recommend regularly checking the Flongle adapter by inserting the empty adapter and completing a hardware check. For checking the device or flow cell position, use a MinION CTC, even if a Flongle Flow Cell will be used for sequencing.

2. Navigate to the Start homepage and select the 'Hardware Check' option.

   The hardware check page will open.
   

3. Select 'Start' on the Hardware Check page to start check.

   Note: To check the Flongle adapter, insert the EMPTY adapter. To check device or position, insert only a MinION CTC.

   

4. You will be automatically navigated to the Sequencing Overview page.

   A loading bar will be displayed under the flow cell during the check.

5. End of Step The hardware check will complete after approximately one minute.

   Hardware check pass is indicated by a green check icon.

   An orange check icon is a fail.

   1. Flongle hardware check pass
   2. MinION hardware check pass
   3. Flongle hardware check fail

   

   If the hardware check fails, remove and reinsert the CTC, and run a hardware check again. If the check fails for a second time, please contact Technical Support via email (support@nanoporetech.com).

1. Flow cell check

   We strongly recommend performing a flow cell check before loading a DNA or RNA library to assess the number of pores available.

   Oxford Nanopore Technologies will replace any flow cell that falls below the warranty number of active pores within 12 weeks of purchase, provided that you report the results within two days of performing the flow cell check and you have followed the storage recommendations.

   Flow cell	Minimum number of active pores covered by warranty
   Flongle Flow Cell (FLO-FLG001)	50
   MinION/GridION Flow Cell	800
   PromethION Flow Cell	5000

2. Navigate to the Start page and select 'Flow Cell Check' to open the flow cell check page.

   

3. When you see the flow cell type and flow cell IDs recognised, click 'Start' to begin.

   

4. You will be automatically navigated to the Sequencing Overview page.

   A loading bar will be displayed under the flow cell during the check.

5. Flow cell health indicators

   The quality of the flow cell will be shown as one of the three outcomes:

   1. Yellow exclamation mark (Flongle flow cell): The number of sequencing pores is below warranty. Take the flow cell out of the device, re-insert it and run a flow cell check again. If the flow cell is still below warranty, contact support@nanoporetech.com

   2. Green tick (MinION flow cell): The number of sequencing pores is above warranty.

   3. Question mark (PromethION flow cell): A flow cell check has not been run on the flow cell during this MinKNOW session.

   

   Note: The indicator of quality will only remain visible during a MinKNOW session. Once the MinKNOW session has ended, the status of the flow cell will be erased.

1. For instructions on how to set up a sequencing experiment and how to monitor the progress of the experiment, refer to the MinKNOW protocol in the Nanopore Community.

   To run a sequencing experiment, you will need your DNA or RNA sample purified and a sequencing library prepared. For more information about sample preparation, refer to the Prepare section of our Documentation.

   Filezilla can be downloaded for various OS to enable data transfer from your MinION Mk1C.

   The following default options can be entered:
   Host – device ID or IP address (e.g. MC-111414)
   Username – minit
   Password – minit
   Port – 22

   

   If it is your first time connecting, you will be asked to confirm the authenticity of the host. Check the box to Always trust this host, add this key to the cache and click OK to continue:

   

   If the SFTP connection is successfully established, you will see the Mk1C file directory shown on the right-hand side of the UI. Please note that Filezilla defaults to the home directory (/home/minit):

   

   You can navigate to the /data directory by entering /data into the Remote site field and clicking Enter:

   

1. Either press the power button or navigate to the 'Device settings' in the Host settings and click either 'Shutdown' or 'Reboot'.

   

2. Wait for the dialogue box to open and click either 'Shut down' or 'Reboot'.

   

3. Tip The reboot will disconnect the MinION Mk1C from any device that is remotely connecting via Wi-Fi or SSH.

   You will need to reconnect the MinION Mk1C to any device that was connected before the reboot using the procedure described in the Network settings and connection section of this document.

4. End of Step The powering down sequence:

   You will initially see some scrolling code. After ~10 seconds, the screen will go blank and the lights at the side of the screen will power down. It is safe to remove the power cable from the MinION Mk1C at this point, if shutting down.

1. Overview

   MinKNOW is the software used on nanopore sequencing devices. The software is described in more detail in the MinKNOW Technical Document. The MinKNOW Protocol provides instructions on how to use the software.

2. Important Updating the software

   Oxford Nanopore Technologies will post a release note when new software or updates go out via the Nanopore Community.

   We urge users to update as soon as reasonably possible after the release has been made available.

   Note: Please check the information for firewall access to the necessary IP addresses and ranges in this section.

   Users will not be able to update their device if connected remotely or if a run is in progress.

3. Firewall settings for Oxford Nanopore Technologies' devices

   The Oxford Nanopore Technologies software will require access to the AWS IP ranges currently listed here:

   http://docs.aws.amazon.com/general/latest/gr/aws-ip-ranges.html

   Access to the following IP addresses is also needed:

                 178.79.175.200  
                  96.126.99.215  
   

4. Plug an Ethernet cable into the Ethernet port and connect to the network.
5. A dialogue box will open when a new update is available.

   Select Get Update to update the device software automatically.

10. Wait for the software to update; this may take several minutes.

    

11. Check the software version number under 'Current version'.

1. Although MinION Mk1C software can be updated via the user interface, there are occasions where software updates have to be executed manually. This can also be done if the user prefers to update via the command line, since the UI does not give feedback during updates.

   Always refer to the release notes for any version-specific commands that may be supplied.

2. Connect to the MinION Mk1C using SSH.
3. Open a terminal window, and update the list of available software using the following commands:

   
sudo apt clean
sudo apt update
sudo apt install ont-mk1c-release

   
   
   These commands should complete successfully, without any errors or warnings. If you do see an error or warning message, check your MinION Mk1C is able to connect to the Internet. Run the following command to diagnose network connection problems:

   
sudo /opt/ont/mooneye/bin/ont-mooneye-check-network --verbose --diagnose


   Once the commands have completed successfully without errors, please reboot the device using the command:

   
sudo reboot


4. To update all software (operating system and the MinKNOW software), enter the following command:

   
export DEBIAN_FRONTEND=noninteractive
sudo apt upgrade


5. Optional Action

   Alternatively, to update just the MinKNOW software, enter the following command:

   
export DEBIAN_FRONTEND=noninteractive
sudo apt install ont-mk1c-release


6. If you are prompted to continue, type ‘y’ and press Enter.
7. Restart your MinION Mk1C following the update for all processes to complete successfully (this will not be prompted for).

1. From March 2022, we are delivering microSD cards to customers to update their OS so that they can use future versions of MinKNOW (22.03 onwards) with the latest features.

   If you meet the requirements below, you can update your device before the microSD card arrives.

   Note: there is no guarantee this process will work, as not all vendors of microSD cards have been tested internally at Oxford Nanopore.

2. Important Requirements
   • Blank 16 GB+ microSD SDXC card
   • Computer with a microSD port/USB SD card adapter
   • Balena Etcher for Windows or Mac (https://www.balena.io/etcher/)
3. Find out the current version of Ubuntu on your MinION Mk1C.

   If your MinION Mk1C serial number is greater than MC-112454, your device shipped with Ubuntu 18.04 (Bionic).

   Alternatively, on the user interface navigate to Settings and then Software. Click on the ‘I’ icon next to the MinKNOW version: you should see either ubuntu-bionic or ubuntu-xenial.

4. Download the correct SD card image.

   If your Mk1C is currently on Ubuntu Xenial, download the following image (with MinKNOW 21.11 included):
   https://nanoporetech.box.com/s/bsuzar12lvjp15qawz421t9zghk59jw0

   Please visit our Help website for information on how to update MinKNOW on the MinION Mk1C after upgrading to Bionic (https://help.nanoporetech.com).

   The recovery SD card for devices on Bionic is available here (latest image has MinKNOW 22.12.5 preinstalled):
   https://nanoporetech.box.com/s/yftsu9fr9ukqilairdjx8xadtr1u5ygl

   If your MinION Mk1C is already on Bionic, you will need to update to the more stable version if you are unable to update to MinKNOW 22.03.

5. Complete the factory restore.

   Power down the Mk1C. Insert the microSD card and power on your Mk1C. After 30 seconds you should see a System Recovery pop-up screen:

   

   Select Factory Reset to re-image the device with the software on the microSD card.

   Follow the on-screen instructions to complete the OS update.

   If no screen is observed, it is likely you have downloaded the wrong microSD card OS image, so check your OS version again. Alternatively, your device needs to perform some pre-requisite actions, see the Troubleshooting section ("If your Mk1C does not boot from microSD card") for more information. If you have issues, contact support@nanoporetech.com.

6. Update to the latest version of MinKNOW for the MinION Mk1C, which supports the latest chemistry, bug fixes and performance enhancements.

   Please visit our Oxford Nanopore FAQ and Help Centre if you are having difficulties updating MinKNOW on the MinION Mk1C.

7. Completing your OS update

   All sequencing data stored in the /data folder is retained after the OS upgrade. However, please note that you may need to configure some device settings after the update.

   If you use a mounted external storage to the Mk1C, you will need to remount the external storage. Follow the instructions in the Mount network drive section in this user manual.

   If you cannot connect to the internet (you may see the error "Unknown connection 'static'"), follow the instructions in the (Advanced) Network configuration - static vs dynamic IP section in this user manual.

1. Important The MinION Mk1C device has a signing key installed, which is a piece of software used to authenticate MinKNOW updates. On the 16th June 2022 the current signing key has expired, which means you will not be able to update the Mk1C software unless you are either on MinKNOW version 22.05.8, or if you add a new signing key to your device. Below are the instructions for adding the new key to your trusted list via the command line.
2. To add recognition of the signing key to a MinION Mk1C by command line without also updating the software, connect to the device via SSH.

   For details on how to connect via Secure Shell for various operating systems, see the (Advanced) Connecting by the command-line section of this user manual.

3. Once connected, run the command:

   wget -O- https://cdn.oxfordnanoportal.com/apt/ont-repo.pub.2022 | sudo apt-key add -

   This command can also be used for MinKNOW for MinION Mk1B Linux installations.

4. Confirm that you can update MinKNOW via the MinION Mk1C UI after following the steps above.

   If you are unable to update MinKNOW or check for updates, repeat the steps above again. If the issue is not resolved, contact Customer Support at support@nanoporetech.com.

1. Navigate to the Help section of the Host settings.

   

2. In the 'Export Logs' panel, select 'Export'.
3. When the logs are successfully exported, the user will be notified of where they are located.

   The logs will be downloaded as a TGZ file in the logs directory.

   

1. Some Mk1C devices with serial numbers MC-110999 or lower may not be able to recognise the microSD card with OS updates. Follow the steps below to change your device so that boot from SD card works.
2. Copy the file from the link below to your Mk1C.

   https://nanoporetech.box.com/s/2vsqb3d6n5mbbtyrbpu1kyai2p3ohknj

   Use the following command at your PC/Mac command line/terminal, respectively, to copy the attached file to your Mk1C:

   scp ./u-boot.img minit@<your-device>:/home/minit

   Note: if you encounter issues, make sure that your PC/Mac is connected via Ethernet to the same network as your MinION Mk1C.

3. Connect to your device using SSH:

   ssh minit@<your-device>

4. Overwrite the kernel and kernel_b partitions with the image:

   sudo dd if=~/u-boot.img of=/dev/disk/by-partlabel/kernel

   then run:

   sudo dd if=~/u-boot.img of=/dev/disk/by-partlabel/kernel_b

5. Reboot the device:

   sudo reboot now

   Leave the device to boot to completion, and do not turn it off mid-reboot.
