Citrix
The local devices can be selected for redirection when using current Citrix versions, for example,
via Citrix Receiver. Th
ese 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.
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.
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 available
for devices without an integrated USB-to-serial converter (FTDI).
This driver is available for Windows and Linux operating systems and converts the con-
nected USB device into a virtual COM port.
7.4.
Special features of Citrix environments
There is an alternative connection method for signotec signature pads in Citrix
environments. The Virtual Channel technology enables you to use signature
pads without needing the COM port to map on the server. The technology is
also not limited to the use of devices with a virtual COM port, but also supports
native HID and WinUSB devices. In addition, the Virtual Channel connection offers significantly
better performance and stability and is therefore the recommended connection type for compatible
Citrix environments.
Note:
The signotec Virtual Channel driver is required on the client. The driver is available
ex-works for various systems (such as IGEL and Rangee clients). If this is not the case, the
driver must be purchased.
7.5.
Using a USB-to-Ethernet adapter
Signature pads used in HID or WinUSB mode can also be connected to the
signotec USB-to-Ethernet adapter. In this way, the device can be integrated
into the network via IP and is therefore available across several workstations,
for example. The connection via IP can also improve the performance in
terminal server environments. Please refer to the description of the network adapter for more
information.
Note:
The USB-to-Ethernet adapter is only compatible with devices in USB mode and
therefore not with devices operating in virtual serial mode (vCOM).
