2. Your PP8S at a glance
The PP8S has been designed primarily for desktop use, being highly compact and quiet. It
provides 10W of charging power to each of its 8 x USB 2.0 Type-A ports, allowing mobile
devices to be charged quickly, safely and reliably. All ports can be controlled using Cambrionix
software to enable charging and data transfer while monitoring important port and device
information.
The PP8S can charge attached USB devices without using a local computer, and our intelligent
charging algorithm allows almost any device to be charged at its optimum rate (up to 2.1A). The
firmware can be updated to enable new charging profiles, ensuring the PP8S can charge the
latest devices. It is ready to charge out-of-the-box and sync devices when attached to a host
computer.
When a local (host) computer is connected, the host can control the operation of the ports
using freely available software. Device charging and synchronisation can be monitored through
Cambrionix’s LiveViewer App, the Application Programming Interface (API) or Command Line
Interface (CLI). Cambrionix’s free monitoring and control software can be downloaded from
www.cambrionix.com/software

cable to the PSU. Making sure you adhere to local safety regulations, connect the power cable
to the 100 – 250 VAC mains power outlet and switch the hub on using the small power switch
located adjacent to the power input connector on the hub. When the device is switched on, a
red LED will be illuminated. The hub is now ready to charge attached devices.
Periodic inspections should be made to power supply cables and any USB cables for any signs of
damage. If any damage is found, replace the damaged cord before further use.
4.4. Connecting to Host
Once the power is connected, connect the PP8S to your host system using a USB 2.0 Type-A
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 delivered
during data transfer. As indicated in above, if the attached device has a BC1.2 compliant CDP
port, the device can draw up to 2.1A while transferring data.

5. Using your PP8S
In this section, you can find information using your hub in a charge only or a charge and 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 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.
Once the devices are connected, the algorithm will detect the highest charge rate allowable for
each attached device. Charging at the optimum rate (up to 2.1A) specified by the manufacturer
will commence once profiling is complete. Depending on the state of charge of the device
attached, this may take tens of seconds.
5.2. Using when connected to host
5.2.1 Connecting the Hub to a host computer
Connect the PP8S to your host system using a USB 2.0 Type-A 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 2.1A. If the connected device does not comply with BC1.2, the charge
current will be limited to 500 mA in compliance with USB specifications.

PP8S Page 12 of 35
If you wish to limit the charging to your devices whilst connected to your host system then you
can disable CDPon all ports by inputting the following commands.
The CLI commands for turning off the sync charg 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 hub is compatible with macOS®,
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-A 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
ThePP8S appears as a virtual serial port (also called a UART or VCP). On Microsoft™ Windows,
the system will appear as a COM port. 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

PP8S Page 13 of 35
Devices incorporate a FT230X 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 should be set to 115200 baud, 8 data bits, no parity, and
one stop bit. This is sometimes referred to as "115200,8,N,1". No flow control is used. ANSI
terminal emulation should be selected

PP8S Page 14 of 35
5.3. Scalability
If you wish to synchronise more devices, multiple hubs can be connected to allow more devices
to be managed from a single host computer simultaneously.
To daisy-chain multiple hubs, each hub needs to be connected to mains power
individually, and the first hub in the chain should be connected to the local computer through
the hubs’ “host port”. The Host port of the next hub in the daisy-chain is then connected to any
of the first hub's downstream USB ports. More hubs are added in the same way.
way.
Using this daisy-chain approach, a maximum of eight additional hubs can be linked, allowing a
total of 57 devices to be synced from a single host computer. Alternatively, a star topology can
be used, which allows up to 64 devices to be synced from a single computer. In this
arrangement, the first hub is attached in the same way, connecting the hubs host port to the
computer’s USB port. Thereafter, eight additional hubs can be attached to the downstream USB
ports of the first hubs by their host ports as shown below.

PP8S Page 15 of 35
5.4. Manage Ports & Your PP8S
Each port on your PP8S can be managed either individually, or all together. You can turn the
ports off and on, change the port mode, or change the charging profiles. This can be done
either through LiveViewer, or by connecting to the hub via the API.
5.4.1 Port Modes
Charge Turn specific ports or the whole hub to charge only mode (no data
channels open only power)
Sync Turn specific ports or the whole hub to sync mode (data and power
channels open)
Biassed Detect the presence of a device but it will not sync or charge it.
Off Turn specific ports on or off or switch the whole hub on or off. (no
power and no data channels open)
5.4.2 Charging Profiles
To ensure attached devices charge at their optimum rate, our smart USB hubs come with the
below intelligent charging profiles built in:
0 Intelligent charging algorithm which will select a profile 1-6
1 2.1A (Apple)
2BC1.2 Standard (this covers the majority of Android™ phones and
other devices)
3 Samsung
4 2.1A (Profile 1 but with a longer timeout)
5 1.0A (Typically used by Apple)
6 2.4A (Typically used by Apple)

PP8S Page 16 of 35
5.5. Software
More productivity, saving you time. Cambrionix provides three interfaces by which the Hub can
be monitored and managed:
• LiveViewer
• Cambrionix API
• Command Line Instructions
The PP8S uses string commands to communicate with the host system. These can be sent via
the virtual serial port of the PP8S directly, or the API can be used to provide other protocols
that send translated string commands. LiveViewer can use the API to interact with the devices
through a user-friendly application.
There are three different channels for both our LiveViewer application and the API. The three
channels are Alpha/ Beta and Release. We would recommend using the release version of both
the APIand LiveViewer.
We will push bug fixes and updates through Alpha and then onto Beta before it is merged into
the Release version. If you have found a bug that we have a fix for, the Alpha and Beta releases
may already have addressed these and implemented fixes.
5.5.1 Installing Software
Cambrionix has two pieces of software that can be used to manage the devices and your hub
using different host systems. This section has instructions and information on using our
software on three of the most popular host systems.
Our software is available to download from www.cambrionix.com/software, you will find
software available for Windows™, Mac® and Linux® Systems.
To install on Mac® and Windows™ systems, download the install files from the above link, once
downloaded run the install process and dialogue boxes will help you through installation and
initial set-up.
For Linux® systems, download the install files from the website at the above link. Once
downloaded, you can either install it from the desktop GUI or the command line via:
sudo apt install ./

PP8S Page 17 of 35
after this command you will need to enter the file name that has just been downloaded from
our website.
5.5.2 LiveViewer
LiveViewer is an application downloaded from www.cambrionix.com/products/liveviewer.
Once downloaded and installed on the host computer, LiveViewer allows you to switch the
ports on and off, set the port to charge only, or sync mode. LiveViewer’s home page shows 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 port is
in Sync mode, only instantaneous current can be monitored through LiveViewer. When the port
is in Charge mode, the charge profile, current, energy rate, charge duration and end time are
displayed. In addition to individual port information and control, 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.
NVRAMsettings
Within your hub, there are some specific controllable settings called "none volatile
RAMsettings", which are referred to as NVRAM settings. These control a variety of different
settings on your PP8S.
You can navigate to the NVRAM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 and click on advanced.

PP8S Page 18 of 35
Once you have pressed advanced this will take you to the advanced settings page where you
can view and change the NVRAMsettings, including reverting back to default factory settings.
5.5.3 Cambrionix API
Cambrionix API allows you to monitor and control each port in more detail and to integrate
these functions into your own workflow processes. The API comprises a daemon 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 using JavaScript Object Notation
(JSON) Remote Procedure Calls (RPC) over TCP. JSON-RPC calls send a request to the API to
“Get” port, device or Hub information, or “Set” port functions (such as mode). A library of
sample Python code can be obtained from www.cambrionix.com/products/api to help you
integrate many of these functions into your process workflow alongside the complete user
manual.
5.5.4 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.

PP8S Page 19 of 35
You can select when you would like the automatic software checks to take place 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 Alpha, Beta or Release options.
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.
5.5.5 Removing Software
If you wish to uninstall the software (Cambrionix LiveViewer and Cambrionix API) from your
host system, the following steps can do this. One thing to note when removing the API is to
check you have also removed the recorder service which will install alongside it.
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"
