USB redirection on the terminal server
The signotec signature pads feature support for native USB redirection from Windows Remote
Desktop and Citrix.
a)
Remote Desktop
The following steps are required to use this feature on a Windows Terminal Server with RDP
(Remote Desktop):
•
The Windows Terminal Server must have Remote Desktop Session Host (RDSH)
installed in the server roles in Remote Desktop Services (RDS).
•
At the client, the following group policy must be enabled:
Computer Configuration >
Administrative Templates > Windows Components > Remote Desktop Services >
Remote Desktop Connection Client > RemoteFX USB Device Redirection, and enable the
‘Allow RDP redirection of other supported RemoteFX USB devices from this computer’
option.
•
To apply the settings, an update of the mac
hine’s policies (‘gpudpate /force’) and then
a reboot must be performed.
•
When establishing the remote connection, enable ‘Other supported RemoteFX USB
devices’ in the RDP client’s options under ‘Local Resources’ under ‘More...’.
•
An additional icon should be displayed in the connection line of the remote session after
a successful connection to show the available and redirected devices.
b)
Citrix
The local devices can be selected for redirection when using current Citrix versions, for example,
via
Citrix Receiver. These can also be accessed on the Citrix desktop via the ‘Devices’ area and
can be enabled or disabled.
Note:
The connection via USB redirection is supported; however, it offers only an insuf-
ficient or very slow connection speed in some system environments. In this case, we
recommend using virtual serial or Ethernet connections.

Virtual serial connection at the terminal server
Signature pads can be used via a serial interface in a Windows Terminal Server or Citrix environ-
ment.
a)
A device featuring an integrated USB-serial converter (FTDI)
(item no. ends with FT100)
can be addressed via a virtual COM port, which is used to simulate the serial port. It means
that the device can be used as a local resource on a terminal server. To do so, the stand-
ardised FTDI driver must be installed on the client.
b)
The ‘signotec virtual COM port driver’, which must be purchased separately, is avai
lable for
devices without an integrated USB-to-serial converter (FTDI). This driver is available for
Windows and Linux operating systems and converts the connected USB device into a virtual
COM port.
