7.2. 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):
a. The Windows Terminal Server must have Remote Desktop Session Host (RDSH)
installed in the server roles in Remote Desktop Services (RDS).
b. 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.
c. To apply the settings, an update of the machine’s policies (‘gpudpate /force’) and then
a reboot must be performed.
d. When establishing the remote connection, enable ‘Other supported RemoteFX USB
devices’ in the RDP client’s options under ‘Local Resources’ under ‘More...’.
e. 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 insuffi-
cient or very slow connection speed in some system environments. We recommend using
virtual serial or Ethernet connections if the connection speed is slow.
7.3. 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.
The signotec Delta signature pad cannot be equipped with an integrated USB-to-serial converter,
in contrast to the smaller signotec signature pads.
However, the ‘signotec virtual COM port driver’, which must be purchased separately, is available
for them. This driver is available for Windows and Linux operating systems and converts the con-
nected USB device into a virtual COM port.
