1. General
The USB hub is operated using a 12…24 VDC power supply with at least 35 W output power, which is sufficient for
a 900 mA output current on each USB port.
This USB hub has six USB 3.0 downstream ports, which can be turned on and off individually via USB. When they
are turned off, the power supply (+5 V) and the data lines are isolated by semiconductor switches. Control is
provided by the USB hub Toolmonitor (PC software). Whether or not and which ports are active after switching on
the hubs can be configured and stored. The USB 3.0 host connection is usually also used to control the USB hub.
Alternatively, control also can be provided from another host using the additional USB 2.0 connection on the back.
In addition to this control via USB, ports can alternatively also be turned on and off via external control inputs.
Whether or not and which ports are active after switching on the USB hub (for example to have access to the
mouse or keyboard) can be stored in non - volatile storage.
A number, that can be stored in the device, can be used to distinguish between multiple USB hub 3.0 6-Port units
on one PC.
The USB hub is controlled through a virtual serial interface with simple text commands (see chapter 8). This makes
is possible to use the USB hub under Linux as well. If the operating system does not already provide native support
for USB serial converters from FTDI, Linux drivers can be found at http://www.ftdichip.com/Drivers/VCP.htm.
The Toolmonitor USB hub 6-port can also be installed, which provides a user interface for the control and
configuration of the USB hub. It communicates to the USB hub through the virtual serial interface and in turn offers
an interface for remote control. COM / DCOM or a .Net assembly can be used as the interface. This allows the
USB hub Toolmonitor to be integrated into many different applications (MCD TestManager CE, LabView®,
Microsoft Visual Studio® (C#, C++, Visual Basic), Microsoft Office® (for example Excel®), Open Office®). There is
also a command line tool available. This USB hub 3.0 6-Port with two control inputs can also be implemented for
Linux operating systems, if required.
Order number: # 153780

3. Safety Instructions
The USB hub 6-Port is intended for use indoor. It may not be exposed to moisture. Except for the fuse, the device
has no parts that can be replaced by the user. Any repair must be carried out by a trained technician. Before
opening the housing, all cables must be disconnected from the device.

4. Installation of Software, Drivers and Hardware
4.1. Installation of Software
On the USB storage card included, the “Drive:\Software\Installer“ directory contains the installation file for the
Toolmonitor. To install it, start the file “USBHub6Install.msi“ and follow the instructions of the installation dialog.
4.2. Installation of Drivers
The drivers for the USB hub are integrated into the operating system. For the controller, the driver under Windows®
(Windows® 7 through Windows® 10) is automatically downloaded from Windows® Update. For older Windows®
versions (starting with Windows® XP) or if no Internet connection is available, the driver can be installed manually.
The installation file for this driver is on the USB storage card included, in the “Drive:\Software\Drivers“ directory.
Start the file “CDMxxxxx_Setup.exe“ file located there (xxxxx is a number denoting the version number). After
installation, it will take another few seconds before the USB hub is ready to use.
The USB storage card provided cannot be operated on the USB hub without a power supply. Please connect
a suitable power supply to the USB hub or plug the USB card into a USB connector on your PC.
4.3. Connecting the Hardware
The USB hub is powered by a 12…24 VDC power supply (self - powered) with at least 40 W output power, which is
sufficient for 900 mA output current on each USB port, including the power supply of the hub itself. Weaker power
supplies can lead to functional problems due to overload.
Weaker power supplies can be used. However, it is then the user's responsibility to ensure that they are not
overloaded. Signs of overload are dropped connections and error messages related to excess USB current.
The connection for the external power supply is a DC connector with a 2.5 mm inner diameter and 5.5 mm outer
diameter. The plus pole is on the inner contact.
Some USB devices with their own power supply have leakage currents that are conducted through the host to the
ground and shield. These currents can cause functional problems in the device or the host. The functional ground
connection should help prevent such critical configurations. It is connected to the potential of the housing and the
cable shields, and should be connected to a ground potential.
We discourage from connecting the functional ground to a dirty ground point, since this tends to lead to more
connection drops and downtime.

Figure 1: Front View of the USB hub
The USB hub can be controlled either through the hub input ("USB", on the right) or an external control
("ext. Control", on the left). If the external USB control input is connected to another host, control is carried out
through it and only the pure USB hub functionality will remain on the hub input. Alternatively, if configured correctly
the USB ports can also be turned on and off from the parallel input.
If no USB host is connected to the hub input ("USB", on the right), then all USB ports are turned off or remain
off. The exception to this rule are pure charging ports (DCP or charger - emulation), if a power supply is
connected. Only if a USB host is connected and as long as it stays connected will the ports be turned on as
configured.

5.6. Function of the USB Ports
Operating Modes 5.6.1.
The USB hub provides six high - speed - capable USB 3.0 ports. Each port can be configured to one of four modes.
These four modes are:
1. Standard port (SDP):
If the maximum current is exceeded, the port shuts off.
2. Charge - capable port (CDP):
Like a standard port, but it announces itself to the connected USB device as a charge - capable USB port
according to the USB battery charging specification V1.2 (USB-IF BC1.2 CDP).
3. Dedicated charging port (DCP BC1.2):
The port announces itself to the connected USB device as a dedicated charging port according to the USB
battery charging specification V1.2 (USB-IF BC1.2 DCP). The current is limited to the maximum possible
value. In this mode, no USB communication is possible with the connected device!
4. Charger - emulation:
The port attempts to negotiate a charging protocol with the connected device. To do this, it tries different
variants one after the other, including YD/T-1591 (2009) and variants compatible with many portable
devices from Apple® and RIM®. The current is limited to the maximum possible value. In this mode, no USB
communication is possible with the connected device!
Dedicated charging port connection and charger emulation can also be active without a host connected
(operation as a standalone charger).
Due to the many charging schemes – some of which are manufacturer - specific – there can be no guarantee
that battery charging will succeed with a particular mobile device and that no damage can result!
Connection Detection 5.6.2.
The USB ports have a function to detect when a USB device is connected. This also works for connected devices
that only use the power from the connection (such as USB fans or reading lights). Connection detection can be
disabled individually for each port if the small test current should lead to unexpected problems.
Some USB devices that have their own power supply draw very little power from the USB port. This type of
device can consequently not be detected and the USB port will not be fully enabled. In this case, connection
detection must be disabled for this port.
In CDP mode, it may be that the connection detects a device, but does not detect when it is disconnected.
This has no effect on the other functions of the USB hub, however. Connecting a normal USB device or
turning the port on and off will reset connection detection again.

Elektronik GmbH USB hub 3.0 6-Port, 2 Control Inputs Manual
Page 9 of 18
Current Measurement 5.6.3.
Each USB port has a mechanism to measure the current, with a resolution of about 10 mA. This permits the actual
current consumption of the connected device to be measured and monitored. This applies to both operating
currents of USB devices and non - USB devices as well as charging currents.
Current Limitation 5.6.4.
The switching threshold for current limitation can be configured individually for each USB port in steps of 500 mA to
up 2500 mA. Current limitation is in principle configurable regardless of use, but the following limits are
recommended:
Mode
Current limitation
Standard port (SDP)
900 mA
Charge - capable data connection (CDP)
1500 mA – 1800 mA
BC 1.2 dedicated charging port (DCP)
2000 mA – 2500 mA
Charger - emulation
2000 mA – 2500 mA
Most USB connectors are specified at 1.5 A to 1.9 A. So in general, a current limitation of no more than 2000
mA should be configured. The total output current can be no greater than 6000 mA. If an attempt is made to
configure a higher limit, an error message will occur. The power supply connected must be able to provide the
output current and the operating power for the USB hub (see technical data, chapter 7) at a stable voltage of
12 V to 24 V.
Host Notification 5.6.5.
If too much current is drawn from a USB port, it shuts off and notifies the operating system. User intervention is
then required to restore the USB port to operation. In automated systems, this may be undesired. For this purpose,
host notification can be disabled for certain USB ports or for all of them. A restart is then carried out via the
controlling application. To do this, the port in question must first be specifically turned off and then back on.
The response of the operating system to overload events may differ from the behavior described above,
depending on the version and the driver used.
Connection Type 5.6.6.
It can be specified for each individual port whether it has established a USB 2.0 or USB 3.0 connection. The
connection to the host (PC) can also be queried in the same way.

Figure 9: USB Hub Configuration
A checked box in this column causes the corresponding USB port no longer to be turned on and off via
USB, but rather from the corresponding signal on the parallel input.
This setting only has an effect if the corresponding port is set to parallel port control ("External
controlled"). If this checkbox is checked, the USB port is turned on for a high level on the corresponding
parallel input; otherwise, for a low level. An open parallel port input corresponds to a high level.
This setting only has an effect if the corresponding port is not set to parallel port control ("External
controlled"). Turns the corresponding USB port on when the box is checked.
Turns connection detection on. In DCP mode and charger - emulation, connection detection is
necessary for correct functioning. Devices that consume less than 1 mA from the USB port are
frequently not detected and the port is then not released. For this case, connection detection can be
turned off.
Places the corresponding port into SDP, CDP, DCP, or charger - emulation mode.
This function reports an excess current event to the operating system and leaves further handling to it.
Without this function, the port will turn back on as soon as the overload is removed. Host notification is
available only for the first four ports.
Sets the current limitation per port. In total, at most 5000 mA can be set. Without a power supply, at
most 100 mA per port is permitted (500 mA total).
Reads out the current configuration.
Applies the configuration set in the dialog. It will be lost when the power supply to the USB hub is lost.
Reads out the configuration currently stored.
Saves the configuration set up in the dialog, but does not apply it. This configuration is restored by the
USB hub after uninterrupted power supply is restored.

8. Interface Description
The command line interface uses simple ASCII strings. Recognized valid commands are acknowledged with the
string "ok" if the command is a configuration command. For a read command, the corresponding data is sent. An
unrecognized command is answered with "???". In ready mode, all configuration commands are answered with
"off". A prefix "D" changes no current settings, but rather specifies a write or read access to the non - volatile
memory from which the configuration will be taken when the USB hub is turned on. All strings are terminated with a
CR (ASCII 13).
