Elektronik GmbH USB hub 2.0 8-port Manual
1. Safety instructions
The USB hub 2.0 8-port is intended for use indoors. It may not be exposed to moisture. If the device is brought
from a cold environment into a warm one, it must be allowed to stand for at least one hour without the power
cord and other cables connected until any condensation moisture has dried.
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, disconnect the power cord and wait for about a minute.
2. General information
This USB hub has eight USB 2.0 downstream ports that can be turned on and off individually via USB. When they
are turned off, the power supply (+5V) and the data lines are isolated by semiconductor switches. Control is
provided by the USB hub Toolmonitor (PC software). Whether ports are active after the device is turned on, and
which ports, can be configured and stored.
Each USB port can be configured as a standard port (SDP), charging-capable connection (CDP), or a charger
connection (DCP) and provides the connected device with up to 2.5A.
In addition to the USB ports, the USB hub also has an 8-channel relay multiplexer that can be used to turn a
centrally connected voltage (at most 48V) on each port individually on and off independently from one another,
for example for supplying a device with a voltage other than 5V. The connection uses a 4mm banana plug.
Whether and which ports should be activate after the hub is turned on (for example to have access to the mouse
or keyboard) can be stored in non-volatile storage.
A switch on the device can be used to turn off all ports temporarily or to restore the previous switching state of
all ports.
A number that can be stored in the device can be used to distinguish between multiple USB hub 2.0 8-port units
on a PC.
External software can be used to control the USB hub Toolmonitor completely remotely. 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 ®). It is also possible to use the USB hub under Linux.

4.2. Installing drivers
Connect the USB 2.0 HUB 8 to a free USB port and turn it on with the switch on the back. The actual USB hub is
detected automatically by Windows and appropriate drivers are installed. Additional drivers are required for the
control components. The following options are available:
1) If the PC has access to the Internet, starting with Windows 7 ® the driver is automatically loaded and
installed by Windows Update.
2) Alternatively, the driver can be loaded and installed from http://www.ftdichip.com/Drivers/VCP.htm.
For a simple installation, please click "setup executable".
3) If "MCD USBHub8Monitor" is included, after it is installed the driver can be found and installed in the "USB
Driver" directory of its installation directory.
By default, the installation path is:
<Drive name>:\MCD Elektronik GmbH\MCD USBHub8Monitor\USB Driver
4.3. Installing Toolmonitor
The USB 2.0 HUB 8 can be completely controlled via text commands (see Chapter 11 on p. 20). Optionally, the
USBHub8Monitor can be installed as a graphical user interface and as an interface for other applications. To do
this, start the USBHub8Install installer (EXE or MSI file) and follow the instructions in the installation dialog. After
installation, the Toolmonitor can be started from the Start menu.
Under Setup Register COM Server, the Toolmonitor can be registered so that it can be controlled from other
applications.

6. Function of the USB ports
6.1. Operating modes
The USB hub provides eight high-speed-capable USB 2.0 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).
The current is limited to the maximum possible value.
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. Dedicated charging port (DCP)
The port attempts to negotiate a charging protocol with the connected device. To do this, it tries
different variants one after the other, including BC1.2 DCP, 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!
DCP connections can also be active without a host connected.
Due to the many charging schemes – some of which are manufacturer-specific – there is no guarantee
that battery charging will succeed with a particular mobile device and that no damage can result!
6.2. Connection detection
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 (e.g. USB fans or reading lights). Connection detection
can be disabled individually for each port if the small test current should lead to unexpected problems.
In CDP mode, it may be that the connection detects such 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.

6.3. Current measurement
Each USB port has a mechanism to measure the current, with a resolution of about 10mA. 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.
6.4. Current limitation
The switching threshold for current limitation can be configured individually for each USB port in steps of
500mA to up 2500mA. Current limitation is in principle configurable regardless of use, but the following
limits are recommended:
Most USB connectors are specified at 1.5A to 1.9A. So in general, a current limitation of no more than
2000mA should be configured.

7. Function of the relay multiplexer
The relay multiplexer makes it possible to emit an externally powered voltage on up to eight outputs. This
permits, for example, USB devices to be powered that cannot be operated with operating voltage via USB.
The multiplexers can be switched independently of the USB ports. The connection uses a
4mm banana plug.
The multiplexers are not fused. They can be damaged in case of overload.
Seite 11 von 21
Elektronik GmbH USB hub 2.0 8-port Manual
8. Function of the USB hub 2.0 8-port
8.1. Behavior when power is applied
It can be determined whether the USB goes into normal mode after power is turned on, or initially into
ready mode.
If normal mode is active, then the ports and multiplexers are turned on as configured in advance. If the hub
has not yet been enumerated by the host, all communications ports (SDP and CDP) remain off until
enumeration is complete and will only then be turned on.
In ready mode, the hub acts as though it had been placed in ready mode immediately after being turned on
(see next section). Ports for which no exceptions are defined are not turned on.
8.2. Behavior in ready mode
The button on the front panel can be used to switch the USB hub from normal mode into ready mode and
back. In ready mode, all ports and multiplexers are normally turned off; however, exceptions can be defined
for devices that should not be turned off (e.g. for the mouse/keyboard or for charging ports). Ports or
multiplexers that are already switched off, however, are not turned back on in ready mode, even if an
exception has been defined for them. In ready mode, the hub rejects any command for configuration or
setting of ports or multiplexers from the PC. Read accesses continue to work. This prevents devices turned
off manually from being turned back on by the PC unintentionally.
8.3. Behavior after ready mode
If the USB hub returns to normal mode after ready mode, it either restores the state of the ports
immediately before ready mode or switches the ports to the same state as before the USB hub was turned
on. Which of these two behavioral patterns is followed can be configured.
8.4. Button lock
The button can be locked against unintentional actuation. If this function is saved, the USB will always go
into normal mode after being turned on.
8.5. Saving the configuration
All settings can also be written to the hub for storage. In this case, the currently active settings are not
affected. Saved settings will be restored the next time the hub is turned on.
The storage cells for configuration are subject to a certain amount of wear (> 100,000 write cycles). The
storage commands should therefore not be executed within a program loop or the like.
The USB ports always change mode only after the device is turned off and on again.
8.6. Recognition number
The USB hub can permanently store a number (00 to FF hexadecimal, or 0 to 255 decimal) that can be
queried later. This helps distinguish between multiple hubs on a PC. Otherwise, this number has no function.
Seite 12 von 21
Elektronik GmbH USB hub 2.0 8-port Manual
8.7. Resetting
Pushing the button on the front panel for about 10 seconds resets the USB hub to factory settings. The hub
then restarts. The ports and multiplexers will be switched accordingly. This must be followed by the
corresponding command. If the button lock is active, this function is not possible. The factory settings
include:
Normal mode after power on
No exceptions for ready mode
After ready mode, restore the state from before ready mode
All USB ports are standard ports (SDP)
Current limitation of all ports is 2.5A
Connection detection for USB devices is enabled
The button is unlocked.
All USB ports are off after the USB hub is turned on
All relay multiplexers are on after the USB hub is turned on
The recognition number is not changed
All USB ports are turned off by a reset. Disconnect all connected storage media from the operating
system beforehand.
The relay multiplexers will all be turned on. Disconnect any connections for which this is not desired.

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).
