Getting Started

This manual provides a reference for end-users installing for the first time and using their hub afterwards. As well as a guide for product safety-related information.
The OEM-PDS-C4 is intended to be used in an indoor static environment in which the environment falls within the tested specifications to provide charge, sync and management functionality. Please see the physical specifications section of this manual for information on the environment specifications.
4.1. Unpacking your product
When you have received your product, please check the packing slip inside the box to ensure all contents and quantities are correct before opening. This is to avoid retesting and repackaging any items that are not required.
When opening the packaging, use a suitable method to open the box i.e, do not use a knife. This is to ensure the product is not damaged.
CAUTION
Personal Injury and Damage to the product
There will be a label on the hub advising you to read the User manual before use. This will need to be removed before use as it may be covering host ports,vents etc.
4.2. What’s Included
OEM-PDS-C4 Hub
4.3. Connecting to a Host
Once the power is connected, connect the OEM-PDS-C4 to your host system using a USB 2.0 Type-C cable. Using an incorrect host cable may result in the hub and all subsequent ports not being recognised by your host.
Please note that USB specifications require a minimum 100 mA charge current to be available during data transfer. As indicated in above, if the attached device has a BC1.2 compliant CDP port, the device can draw up to 3A whilst transferring data.
4.4. Charging
Your OEM-PDS-C4 will allow your device to charge at the maximum rate possible up to 3A. The way that charging takes place is the OEM-PDS-C4 will provide the device with a capability to charge and the devices USB charging controller will determine the maximum amount of charge it wants to draw down.
Although a maximum charge rate of 3A is possible, the device itself determines the exact rate and as such you may not see the maximum amount of charging on every device type that is connected.
4.5. Cables
Some USB cables are data transfer only, and some are power delivery only. There are also options that can handle both tasks. Be sure to verify a cable’s abilities before purchasing it and select a cable which can handle the speeds and power transfer that you require. We would advise using the cable that was provided with the device to connect to our hubs.
4.6. Connecting the OEM-PDS-C4 to the Power Supply Unit using
Spade Connectors
Having ensured the output voltage of the DC power supply is 21V, and certainly does not exceed 5.6  Vdc, connect the PSU to the OEM-PDS-C4 using insulated copper cables of no less than six mm2cross-section and no longer than 150 mm. Longer cables or smaller cross-sections are likely to cause a voltage drop across the cable and improper board operation.
With the mains power supply disconnected, the PSU should be connected to the input spade terminals on the OEM-PDS-C4 using the cable (described above) terminated (at the OEM-PDS-C4 end) with crimp connectors. The positive voltage spade terminal is closest to the OEM-PDS-C4 board edge, and Ground (GND) is marked on the OEM-PDS-C4 board close to the innermost spade terminal.
Taking appropriate safety precautions, turn the mains supply on. Periodic inspection should be made to power supply cables and any USB cables for any signs of damage. If any damage is found then replace damaged cord before further use.

Using your OEM-PDS-C4

In this section, you can find information using your hub in charge or sync application. You can also find information on managing your hub, changing port modes, connecting multiple hubs to one host and using Cambrionix Software.
5.1. Using without connecting to a host
When the Hub is switched on and is not connected to a local host computer it is automatically configured to charge devices using its intelligent charging algorithm. Connect the devices to be charged to any of the available ports (not the Host Port) using USB – compliant cables.
5.2. Using when connected to a host
5.2.1 Connecting the Hub to a host computer
Connect the OEM-PDS-C4 to your host system using a USB 2.0 Type-C cable. Using an incorrect host cable may result in the hub and all subsequent ports not being recognised by your host.
5.2.2 Charging
When the Host Port is connected to a local computer, the hub defaults to Sync mode and charge currents are determined according to USB Implementers Forum (USBIF) Super-Speed USB3 specifications. If the attached device complies with USB-IF Battery Charging specification BC1.2 and supports Charging Downstream Port (CDP), the hub can provide high-speed charging at 1.5A. If the connected device does not comply with BC1.2, the charge current will be limited to 500mA in compliance with USB specifications.
If you wish to limit the charging to your devices whilst connected to your host system then you can disable CDP. You can disable CDP through Internal hub settings either by going through the advanced settings and turning “Sync charge” off or through the API and disabling it via code. For example, the instructions would be below using the command line. The CLI commands for turning off the sync charge options, with a 1 or 0 per port.
settings_unlock
settings_reset
settings_set sync_chrg 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
settings_set alt_sync_chrg 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
reboot
This can also be done via the API if this is easier. Just supply that string (joined with \n) like:
cbrxapi.cbrx_connection_set(handle, “Settings”, “settings_unlock\nsettings_reset\nsettings_set
sync_chrg 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0\nsettings_set alt_sync_chrg 0
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0\nreboot”)
Note that settings_reset clears any previous settings, so if you need to retain something else, it would be better to issue settings_display first, which gives you the entire settings which you can then modify and re-issue in entirity.
5.2.3 Data Transfer
If you wish to transfer data, change applications, restore or update your mobile device, a data  connection to a local host computer is required. The Cambrionix API and software is compatible withmacOS®, Windows™ and Linux® operating systems and can transfer data between these operating systems and many mobile operating systems such as iOS™ and Android™.
In order to transfer data, connect the host port to your local (host) computer using a USB 2.0 Type-C compliant cable. Any devices connected to the hub will now appear as if they were connected to the host computer’s USB port.
5.2.4 Communication Interface and Protocol
The OEM-PDS-C4 appears as a virtual COM port (VCP). On Microsoft Windows™, the systemwill appear as a COM port, the COM port number can be found in device manager. On macOS®, a device file is created in the / directory. S is an alpha-numeric serial string unique to each device /dev/tty.usbserial S
Devices incorporate a USB to UART converter IC from FTDI International. On Windows 7 or later, a driver may automatically be installed (if Windows is configured to download drivers from the internet automatically). If this is not the case, or if a Mac® or Linux® platform is used, the driver may be downloaded from www.ftdichip.com. The VCP drivers are required. For Linux® or Mac computers, the default OS drivers should be used.
The default communications settings are as below, ANSI terminal emulation should be selected.

5.3. Managing Ports & Your OEM-PDS-C4
Each port on your OEM-PDS-C4 can be managed either individually, or all together. You can turn the ports off and on, change the port mode, or change various other settings applicable to the OEM-PDSC4 more information can be found in the LiveViewer section under Internal hub settings. This can be done through LiveViewer, the CLI or by connecting to the hub via the API.
5.3.1 Port Modes

and no data channels open, mimics unplugging the device)

5.3.2 Switching port modes
You can switch between port modes by using LiveViewer, the CLI or by connecting to the hub via the API. If you switch a port off then this will stop any connection taking place to the USB device and would mimic unplugging the USB device completely from the host system.
You can disable CDP through Internal hub settings either by going through the hub settings and turning “Sync charge” off or through the API and disabling it via code. For example, using the command line, the instructions would be as below.
settings_unlock
settings_set sync_chrg 0000000000000000
5.3.3 Charging Profiles
To ensure attached devices charge at their optimum rate, our smart USB hubs come with the below intelligent charging profiles built in:
5.3.4 Firmware
The firmware can be kept up to date using our LiveViewer software. As part of delivering an easy user experience, our LiveViewer application is now a set- and-forget solution. The LiveViewer application will discover your USB hub’s firmware and present an update for you.
To update the firmware, first, go to the firmware section of LiveViewer. Here you can see the available Firmware versions to install to the hub.
The current firmware version on the hub is displayed in the firmware section alongside the hub’s name. This will appear red if a newer version is available or green if it is the most up to date.To install the firmware onto the hub click the hub(s) connected that you want to update, the latest  firmware will be automatically selected, if you wish to change the firmware version you are updatingto then this can also be done. Once selected press the update button at the top and the update will commence.
CAUTION
Your OEM-PDS-C4 may not function correctly
Do not downgrade firmware onto a new product
CAUTION
Your Cambrionix Firmware may get corrupted
Do not interrupt the Firmware update process.
Do not disconnect the power during the update process.
CAUTION
A new version may be available
Ensure you have the latest version of Firmware installed on your hub. These updates will often contain new features, fixes for bugs and performance improvements
5.4. Software
Cambrionix provides interfaces by which the Hub can be monitored and managed:

• LiveViewer
• Cambrionix Connect
• Cambrionix API
• Command Line Instructions

LiveViewer or Cambrionix Connect can use the API to interact with the devices through a user-friendly application, or the API can be used to provide other protocols that send translated string commands.
The OEM-PDS-C4 uses string commands to communicate with the host system. These can be sent via the virtual serial port of the OEM-PDS-C4 directly,
There are different channels for both our LiveViewer application and the API. The channels are Beta and Release. We would recommend using the release version of both the API and LiveViewer.
We will push bug fixes and updates through Beta before it is merged into the Release version. If you have found a bug that we have a fix for, the Beta releases may already have addressed these and implemented fixes.
5.4.1 LiveViewer
LiveViewer is an application downloaded fromwww.cambrionix.com/products/liveviewer . Once downloaded and installed on the host computer, LiveViewer allows you to switch the ports on and off and set the port mode. LiveViewer’s home page shows the hubs available, by selecting a hub you can obtain the following information about all the ports:

• Status (Attached/disconnected)
• Mode (Charge/Sync/Off)
• Profile (Charging profile)
• Duration (How long the device has been attached)
• End time (Time the battery reaches a threshold (full) level)
• Current (Quick charge current in mA)
• Energy (Present energy rate)

Tick boxes adjacent to each port symbol allow that port mode to be changed when the “enable port controls” is selected. LiveViewer shows the hub rail voltages, time since switched on, total current and power, and temperature. Further details on LiveViewer are available on our website. www.cambrionix.com/products/liveviewer
Internal hub settings
Within your hub, there are some specific controllable settings called ‘internal hub settings’. These are a variety of different settings for your OEM-PDS-C4.
You can navigate to the Internal hub settings by opening LiveViewer and selecting the hub you want to connect to. Once you have chosen the connected hub, navigate to the below icon on the top right of the screen from LiveViewer or Connect

Once you have pressed this you will be taken to the Internal hub settings section where you can view and change the Internal hub settings, including reverting back to default factory settings.

Empty
Attach Threshold (mA)| The attach threshold is the device current (mA) level at which the hub can determine that a device (iPhone etc.) has been attached to a port. The attach threshold may need to be increased if the device (iPhone etc.) is connected to a Cambrionix port with a cable which includes an LED or
other electronics. It may also need to be increased if you are using a device (iPhone etc.) with a 3rd party sled/holder/case (such as a barcode scanner or battery pack) which contains electronics or charging passthrough| 10

*Charging Downstream Port (CDP) Being enabled means that a port is capable of transferring data and charging the device at the same time with a higher current than just data syncing alone. With CDP enabled the hub can supply up to 1.5A
If you disable CDP you will receive the notification “This Hub has the Charge Downstream Port UCS mode disabled. This could limit the maximum current seen on some ports.” This notification is there to ensure you havent turned this off by accident and can still have the highest charge available.
There is more information on the Internal hub settings and how to manage them in our CLI manual. which can be found at the link here.

CAUTION
A new version may be available
Ensure you have the latest version of LiveViewer installed on your host system. These updates will often contain new features, fixes for bugs and performance improvements
5.4.2 Cambrionix API
The Cambrionix API allows you to monitor and control each port in detail and to integrate these functions into your own workflow processes. The API comprises a daemon (which is a program running in the background) that can be downloaded from www.cambrionix.com/products/api and installed on the host machine. Port information and control can be provided through the API. Calls are sent as a request to the API to “Get” port, device or Hub information, or “Set” port functions. A library of sample code is downloaded along with the API from the following link www.cambrionix.com/products/api and can be found within the program files under ‘examples’. These can help you integrate many of these functions into your process work-flow alongside the complete user manual.

CAUTION
A new version may be available
Ensure you have the latest version of API installed on your host system. These updates will often contain new features, fixes for bugs and performance improvements
5.4.3 Updating Software
By using LiveViewer you will be able to automatically download and install the most up to date software (LiveViewer and the Cambrionix API)
By going into the settings section on the left-hand side of LiveViewer, you can navigate to the general tab, and under this can see the options for keeping both LiveViewer and the API up to date.By default LiveViewer will check for updates regularly or, if you prefer, you can change to a manual update selection. You can also select which version of the software you would like to use between the Beta or Release options. You can also select historic versions of the API and LiveViewer to install.
When you have some software updates available, you can select install now to begin the installation process; a progress bar will appear to show the installation status. From this bar, you can also view the release notes for the version of the software you are looking at.
5.4.4 Removing Software
If you wish to uninstall the software (Cambrionix LiveViewer, Cambrionix API and the Cambrionix Recorder Service) from your host system, the following steps can do this.
Windows™
To remove the software from a Windows™ system, you can do so by going into “Add or remove programs” finding the software you wish to remove, selecting it and pressing “uninstall” macOS®
To remove the software from a macOS® system, locate the application in the Finder, drag the application to the Trash, or select the application and choose File >Move to Trash. You may be asked to enter the name and password of an administrator account on your Mac®. Then to completely delete the application, choose Finder > Empty Trash.
Alternatively, use the below instructions.
sudo /Library/Cambrionix/ApiService/bin/CambrionixApiService –remove
sudo /Library/Cambrionix/ApiService/bin/CambrionixRecorderService –remove
Linux®
To remove software on Linux® there are two options.
The first is to use the Software centre, then either the list of installed applications or the search bar to find the software you wish to remove. Once you have selected the application, click on the remove button and you will be prompted for a password, enter the password and the software will be removed.
The second way you can remove software is by using the command line. All you need to do is to use the command in the following fashion:
sudo apt remove program_name

You’ll be asked to enter your account password. When you enter it, nothing is visible on the screen.
You will need to confirm removal, it will ask for your confirmation, press the enter key or Y key: Keep in mind that you’ll have to use the exact package name in the apt remove command otherwise, it will show ‘unable to locate package error‘. You can type the first few letters of the program you want to uninstall, and then hit the tab key. It will show all the installed packages that match those letters at the beginning of their names.
5.4.5 Command Line Instructions (CLI)
Command Line Instructions can be used to control and monitor the functions of the hub and attached devices. To use the command-line interface a serial terminal emulator must be installed on the host computer. Examples include PuTTy, Serial, ZTerm, and Minicom. If you would like more information, please look at our more in-depth information here: www.cambrionix.com/cli
Two example commands can be seen below, you can use these commands to check hub information and health.

5.5. Scalability
If you wish to synchronise more devices, multiple OEM-PDS-C4 can be connected together (either in a star topology or daisy chained) to allow up to 20 devices to be managed from a single host computer simultaneously
In order to daisy-chain multiple OEM-PDS-C4, each OEM-PDS-C4 needs to be connected to mains power individually and the first OEM-PDS-C4 in the chain should be connected to the local computer through the “host port”. The host port of the next board in the daisy-chain is then connected to any of the first OEM-PDS-C4 downstream USB ports. More boards are added in the same way.
Using this daisy-chain approach, a maximum of three additional boards can be linked, allowing a total of 20 devices to be sync’d from a single host computer.
For more information on endpoints, connecting multiple devices and calculating howmany devices you can connect to your host system please see our technical note on endpoints.
5.6. Cooling the OEM-PDS-C4
The safety features of the product include an over-temperature feature that causes the board to temporarily shut down when the board temperature exceeds 65°C board temperature can be measured using a temperature sensor placed at the location shown in the diagram below.
Temperature can also be monitored via our API, LiveViewer App and the command line interface.
When measuring temperature to determine if forced cooling is required, the temperature should be measured whilst the OEM-PDS-C4 is under full load and at the highest ambient operating temperature.
Forced cooling may be required if the board is operated inside an enclosure and/or at high ambient temperatures. We recommend using a fan monitoring fan flow-rate and position to ensure the unit remains below 60°C.
The fan connections are made using 2/3 pins of the 4-pin connections. Two types of connection are possible:
a) Constant speed – Connect the fan using two wires to +5Vdc and GND
b) Variable speed – connect the fan using +5Vdc, GND and PWM

5.7. Cleaning your OEM-PDS-C4
Cleaning the product is generally not required, although in some instances it may be necessary if excess dirt/ dust/ hair has accumulated, or if minor liquid spillages have occurred on the module during operation or storage.
CAUTION
Electric shock or personal injury may occur
If there is a dirt/ spillage over a ventilation slot, external data/ power connector or product aperture, please remove power from the unit without touching the liquid and seek advise before reapplying power

• Ensure that the product is switched off and the power cord is removed from the product. Hold the power cable by the plug and do not touch either the plug or the power cord with wet or damp hands as an electrical shock may result
• Wipe the product with a clean, dry and soft cloth. Do not use detergents which contain alcohol, solvent or surface-active agents. Do not spray water or detergent directly onto the product Mildly dampen a soft and dry cloth in water and wring thoroughly to clean the product as required
• Dry the product thoroughly once the cleaning has finished
• Reconnect the power cord and use your product as advised once cleaning is complete

Ports Lifetime
Standard USB connections have a minimum rated lifetime of 1,500 cycles of insertion and removal.
USB-C receptacles have a minimum rated lifetime of 10,000 cycles of insertion and removal. This is an industry-standard.
One thing you can do to prolong the lifetime of the ports on your OEM-PDS-C4 is to use “sacrificial cables” in between the hub and your charging cables so when you repeatedly connect/ disconnect you are only going to wear the cables rather than the hub.
6.5. Consumables and Placing Orders
Below is a list of any Consumable products you may require for your OEM-PDS-C4 including the cables you will require to connect devices to the hub.
Cables…………………………………………… USB 2.0 Type-C
If you require any spare parts, such as the power cable or USB 2.0 Type-C cable, these can be ordered by quoting the product part number and the spare part number (available from the Getting Started section).
These can be ordered from the reseller or solution partner you purchased your OEM-PDS-C4 from, or from Cambrionix directly.

Troubleshooting

If you experience any issues with your OEM-PDS-C4; please try the following troubleshooting steps, if the issue is not addressed in this section, please get in touch with your local vendor or Cambrionix. To contact Cambrionix Support please see Help and Support.

7.1. Common troubleshooting tips
Some tips and information to check first.
If you directly connect the same device to the port the hub is in, does it appear to the OS.
If you plug a device (phone, USB stick) into the hub, does it appear to the OS (device manager/system info etc.).
Try switching the cables with ones that are working/ use cable from a hub that is working.
7.2. Logging through LiveViewer
If you are experiencing a bug or an issue, we may ask you to obtain some logs of the behaviour, to see in more detail what is happening. To get logs of the behaviour use the following steps to get a zip file of the logs.

1. Open LiveViewer (if this is not already downloaded, then go onto our website and download both the API and LiveViewer) www.cambrionix.com/software
2. Once in LiveViewer, on the left-hand side of the screen, select the settings section.
3. Once in the settings section, select the API tab.
4. In the API section click the “cog” button on the right hand side of the local API
5. Click the “select all” tick box and then the save button.
6. After this is enabled, use the hub in a way that causes the issue you are seeing.
7. Wait for the issue to occur, i.e. device disconnects.
8. Make a note of the time and date that the issue occurs then go back to the API page in LiveViewer, and press the zip logs.
9. Once you have the logs un-tick the “select all” box and save your settings.
10. Send the logs to us for us to take a look at.

The API keeps a maximum of 20 logs at 256Mb each, so the latest one is usually smaller. If a crash occurs, you would see a smaller log file and the next instance of API shuffles the existing ones
7.3. Hardware Failure
If the Hardware fails the LEDs can flash in a pattern to determine the type of failure. The power LED will flash the pattern if no LEDs are present on the downstream ports.
The unit will blink four times, followed by eight long or short flashes, which then repeat. The flashes are a number in binary which match a number in our error code list.
i.e if the LED flashes the following – BBBB SLSSSLSS, the binary number is 01000100.
7.4. Device connection
If you are seeing any device connection issues please read through the following trouble shooting steps to see if this resolves the observed behaviour.
Device issues when updating
We have found that during updates on some devices the connection can be dropped or lost on the device, this is due to devices going in and out of the bootloader and requiring different power levels.
In most instances disabling CDP and changing the ports to always be on has resolved this issue for our customers.
You can disable CDP through Internal hub settings either by going through the advanced settings and turning “Sync charge” off or through the API and disabling it via code. For example, the instructions would be below using the command line.
settings_unlock
settings_set sync_chrg 0000000000000000
You can set the ports to always be on through Internal hub settings through the advanced settings and turning “Ports On” settings to always on for each port. When you set the port to always be on you will need to set a default profile on each port for when the port(s). There is a desription for each profile within LiveViewer or Cambrionix Connect.
Unstable device connection
Some devices can have unstable connections with your host system through the OEM-PDS-C4. We have only observed this behaviour in a very few amount of devices, disabling CDP and setting the ports to always be on has resolved all issues and the connections are stable.
You can disable CDP through Internal hub settings either by going through the advanced settings and turning “Sync charge” off or through the API and disabling it via code. For example, using the command line, the instructions would be as below.

You can set the ports to always be on through Internal hub settings through the advanced settings and turning “Ports On” settings to always on for each port. When you set the port to always be on you will need to set a default profile on each port for when the port(s). There is a description for each profile within LiveViewer or Cambrionix Connect.
Battery information for Android
If you are observing an issue displaying battery information on Android devices ensure firstly you have ADB tool installed and open then try these things in order.

1. Check that developer options are enabled on the android device, and then that USB debugging is also enabled.
2. If you have done this step and it still does not work, go to Developer Options and click ‘Revoke USB debugging authorisations’. Unplug the cable and reconnect.
3. If this still doesn’t work, turn off the developer options at the top, re-enable it, and re-enable ‘USB Debugging’.
4. You can get detailed info directly from ADB at each step to diagnose things:
   adb.exe shell dumpsys battery # Use -s SERIAL_NUMBER as first options
   if you have more than 1 Android attached

Unknown devices
Sometimes, within Liveviewer and device manager, the connected device may show up as an unknown device.
This can be due to the host system needing to be trusted on the device. This can be done on the device itself on the initial connection.
This could also be due to an insufficient number of endpoints available on the USB controller in the host system. This limitation within the USB controller can only be resolved if you connect fewer USB devices to the controller in question.
For Apple devices there is a setting called “USB accessories” which can be activated, Once activated it will reduce the amount of times a device will need to be unlocked/ trusted.
More information can be found at the link https://support.apple.com/en- gb/HT208857.
Cannot connect any more devices
Sometimes, you may reach the endpoint limit of your USB controller and this may stop you from being able to attach any more devices to your host system.
You can create more space is to change connections from USB3 to USB2. You can change the connection by disabling USB3 in the BIOS on startup.
A much simpler way is to use USB2 cables instead of USB3 cables, limiting the connection to USB2.
7.5. Hub connection issues
If you there are issues with the hub and connecting to your host system, please see below troubleshooting solutions.
Hub not connecting to host
If you see that the OEM-PDS-C4 is not connecting to the host system, one of the issues may be caused by the USB drivers on your host system not being up to date. It is good practice to ensure you have the latest drivers and updates installed on your host system, which is usually handled by the OS, but sometimes may require an update directly from the USB host controllers manufacturer, which will be found on their website.
USB drivers required are FTDI drivers, which can be found on the site https://ftdichip.com/drivers/.

Daisy chaining multiple PDSync-C4 using expansion port
USB C cables can have variations in speed, power, and protocol capabilities. Some “active” or E-mark type-C cables may not work on the daisy chain when connecting the expansion port to another PDysnc-4. We recommend to use “passive” type-C cables and not to use cables fitted with emarkers, see your cable supplier to see if e-markers are fitted.
Cannot access the COM port
You may get an error message stating “COM (and then a number) could not be opened (Access is denied)”.
This is because an application has control over the COM port that the hub is connected to, and no subsequent application can access the hub. To resolve this, you will need to close any other applications that are using the COM port before trying to use the COM port.
7.6. Using with a headless system
If you are using a headless systemwith no GUI, then and you require to enable logging for support issues, you can use the following command to create the logging cfg file manually:
echo
*=DEBUG>/etc/opt/cambrionix/cambrionix.log.cfg
Then after re-producing the problem, you can zip the logs from the folder
/var/log/cambrionix
You may delete the file belowwhen you are finished with it.
/etc/opt/cambrionix/cambrionix.log.cfg
7.7. Software troubleshooting
Some users have noted that the API can cause a high level of CPU usage. This can sometimes be linked to the API recorder service. If you are finding this and you are not using it then we would recommend to uninstall it from your system entirely. Information on how to uninstall programs can be found in the Removing Software section.
Firmware Update
If you have older hardware with Firmware version number lower than 1.83 then the hub may not be compatible with the Cambrionix API and will need to be updated to the latest version of Firmware using the Command Line Updater which can be downloaded and installed from the following link.
