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

4.3.Connecting to the mains
Connect the Power Supply Unit (PSU) to the hub using the 4-Pin DIN plug. Connect the power
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 next to the power input 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.
4.5.Charging
Your PP8S will allow your device to charge at the maximum rate possible up to 2.1A. The way
that charging takes place is the PP8S 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.
4.6.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
advice using the cable that was provided with the device to connect to our hubs.

5.Using your PP8S
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 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
5.2.1Connecting 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.
5.2.2Charging
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.

PP8SPage 13 of 38
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 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.
5.2.3Data 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.
5.2.4Communication Interface and Protocol
The PP8S appears as a virtual serial port (also called a UART or VCP). On Microsoft Windows™,
the system will 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

PP8SPage 14 of 38
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

PP8SPage 15 of 38
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 hub’s “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.

PP8SPage 16 of 38
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.

5.5.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.
5.5.1Installing 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.
Linux® OS systems tested with our software are Ubuntu 18.04 LTS or Debian 9; some other OS
versions based on the two mentioned will work. Some different Linux® OS versions may work,
but we have not tested with them.
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.

PP8SPage 18 of 38
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/.
after this command you will need to enter the file name that has just been downloaded from
our website.
5.5.2LiveViewer
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 and set the port 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 "enable
port controls" is selected. 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 "non-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 then clicking advanced on the bottom of the page

PP8SPage 19 of 38
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.
There is more information on the NVRAMsettings and how to manage them in our CLImanual.
which can be found at the link here.
5.5.3Cambrionix 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 (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 (such as mode). A library of sample 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.
5.5.4Updating 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.
