2.Your ModIT-MAX at a glance
The ModIT-MAX has been designed to provide high-speed data transfer to USB compliant
devices without being constrained by endpoint limits.
The ModIT-MAX can charge attached USB devices without using a local computer. The ModIT-
MAX allows almost any device to be charged at its optimum rate (up to 2.4A). The firmware can
be updated to ensure the ModIT-MAX 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 attached, the host can control the operation of each port using
software provided by Cambrionix. Device charging and synchronisation can be
monitored through Cambrionix’s LiveViewer Application, the Application Programming
Interface (API) or Command Line Interface (CLI). Cambrionix’s free monitoring and control
software can be downloaded from www.cambrionix.com/products/api
With your ModIT-MAX there is a Thunderbolt™ connection to the host which, is capable of up
to , meaning your upstream speeds to the host will be capable of this data transfer rate. The
upstream data transfer rate will be shared amongst the downstream 16 x USB3.2 Type-A
connections.

4.3.Connecting to the mains
Make sure you adhere to local safety regulations, connect the power cable to the socket and
switch the power supply on. The hub is now ready to charge the 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 ModIT-MAX to your host system using a
Thunderbolt™™ 3 cable. Using an incorrect host cable may result in the hub and all subsequent
ports not being recognised by your host.
Cambrionix would recommend using the Thunderbolt™ cable that is provided with our ModIT-
MAX. If you are looking at purchasing your own cable, to achieve 40Gbps a suitable cable would
be either:
l
up to 0.8m passive
l
up to 2m active.
Cambrionix recommend using cables certified by Intel® , all cables with the Thunderbolt™ logo
should have certification.
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 2.4A while transferring data.
4.5.Charging
Your ModIT-MAX will allow your device to charge at the maximum rate possible up to 2.4A. The
way that charging takes place is the ModIT-MAX 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.

ModIT-MAXPage 10 of 41
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.
4.7.Keys
Your ModIT-MAX comes with a set of keys which can be used to manually close and open the
locking mechanisms on all of the slots at once. This will override any other functions on the hub
so that you can secure devices away or make them available to remove.
These keys are provided with your ModIT-MAX but if you need any replacement's or spares you
can contact Cambrionix to organise a new set to be sent out.

5.Using your ModIT-MAX
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.
5.0.1LED Configuration
Your ModIT-MAX has inbuilt LEDs used to show the state of the ports or devices. These LEDs
can be configured to support your use case; this can be controlled either by using the APIto
send commands directly or through separate software.
The default LED behaviour of the hub is below.
ColourBehaviour
Flashing RedPort is in charge mode and is profiling the device
RedPort is in charge mode and is charging
Green
Port is in charge mode and the device has reached the
charged threshold
BluePort is in Sync mode and has a host connection
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 2.4A) 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.

ModIT-MAXPage 12 of 41
5.2.Using when connected to host
5.2.1Connecting the Hub to a host computer
You can use either Thunderbolt™ host port on the rear of the hub to connect to your host
system; there are two ports on the rear, so you can use one port to connect the host and the
other port to daisy chain multiple hubs.
5.2.2Authorising Thunderbolt™ hubs on Linux®
With Linux® systems, it is necessary to authorise/enrol the ModIT-MAX before it connects.
To do this, you will need to use "boltctl," which is used to control the Thunderbolt™ device
manager. "boltctl" is the command-line interface to interact with boltd, the system daemon
that manages Thunderbolt™ 3™ devices. Using "boltctl", input the following commands to
authorise and enrol your ModIT-MAX.
power [-t | --timeout seconds[
Power up the Thunderbolt™ controller. If the Thunderbolt™ controller is not in "native
enumeration mode", it can be completely powered down by the host firmware/BIOS. On
supported systems, there is an interface to "force" power the Thunderbolt™ controller. If
supported, this command will request the daemon to do so. The daemon will keep track of all
client requests and will release the force power override when the last request is
released.
authorize DEVICE
Authorize a currently unauthorized device identified via its unique id (uuid) DEVICE. If a
key is stored in the database, it will be used, given the security level of the domain
supports secure device connection. Use boltctl list to find out the uuid of a device.
enrol [--policy default] DEVICE
Authorize and record the device with the unique id DEVICE in the database. If the domain
supports a secure connection a new key will be generated and stored in the database
alongside the device and vendor name. The key, if created, will be used in the future
to authorize the device securely.

ModIT-MAXPage 13 of 41
5.2.3Charging
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 2.4A. If the connected device does not comply with BC1.2, the charge
current will be limited to 900 mA 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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.
5.2.4Data 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
Thunderbolt™™ 3 compliant cable. Any devices connected to the hub will now appear as if they
were connected to the host computer’s USB port.

ModIT-MAXPage 14 of 41
In order to transfer data, connect the Thunderbolt™ port of your local (host) computer to one
of the Thunderbolt™ ports on the back of the hub using a Thunderbolt™ 3 compliant cable. A
Thunderbolt™ 2 cable with a Thunderbolt™ 2-3 adaptor can also be used with consequently
reduced data speeds. Any devices connected to the hub will now appear as if they were
connected to the host computer’s USB port. The hub is fully compliant with SuperSpeed USB3.2
and can provide up to 5Gbps data transfer speeds per port. A yellow LED above each port will
illuminate when Syncing. You can use the program of your choice to transfer data to and from
your device. If the attached device has a BC1.2 compliant CDP port, the device can draw up to
1.5A while transferring data.
5.2.5Communication Interface and Protocol
The ModIT-MAX 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
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
5.3.Scalability
USB controllers generally have an endpoint limit, limiting the number of devices that can be
enumerated when connected to the USB3 port of a local computer. USB3 port xHCI host
controllers in most computers limit the number of endpoints enumerated between 64 and 128.
Mobile devices enumerate as more than one endpoint, and complex devices with touch panels
often enumerate as 5 or 6 endpoints. Consequently, the number of devices that can be
successfully enumerated is typically limited to less than twenty.

ModIT-MAXPage 15 of 41
By using Thunderbolt™ connectivity and incorporating host controllers inside the hub each port
can handle up to 16 endpoints. If you wish to synchronise more devices, multiple hubs can be
daisy-chained to allow up to 96 devices to be managed simultaneously from a single host
computer.
To daisy-chain multiple hubs, each hub needs to be connected to mains powerindividually, then
the first hub in the chain should be connected to the local computer through one of the
Thunderbolt™ ports. The next hub in the daisy-chain is connected using one of its
Thunderbolt™ ports to the remaining Thunderbolt™ port of the first hub. A third, fourth and
fifth hub can be added in the same way, connecting the available Thunderbolt™ port of
theprevious hub to one of the Thunderbolt™ ports of the next device in the daisy-chain. Using
this approach, a maximum of six hubs can be linked together, allowing 96 devices to be synced
from a single host computer.

ModIT-MAXPage 16 of 41
5.4.Manage Ports & Your ModIT-MAX
Each port on your ModIT-MAX 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.
5.4.1Port Modes

5.4.3Firmware
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 updater section of LiveViewer. Here you can
see the available Firmware versions to download and install to the hub.

ModIT-MAXPage 17 of 41
The current firmware version on the hub is displayed in the firmware updater 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/ hubs connected that you want to update,
then select the firmware version you want to upgrade to. Once selected press the update
button at the top and the update will commence.
Firmware versions and hardware
We advise not to change the firmware version on any new products you receive as this may
cause compatibility issues and stop your ModIT-MAX from functioning.
CAUTION

ModIT-MAXPage 19 of 41
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 ModIT-MAX uses string commands to communicate with the host system. These can be
sent via the virtual serial port of the ModIT-MAX 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.
