Answer:

Calibration for touchscreens via Teradici PCoIP firmware is designed to work from the OSD in native resolution with elo branded touch screens. To calibrate from a different resolution other than native, the elo device must be bridged and the elo device driver installed.

Bridge the touchscreen device by performing the following steps.

  1. From the zero client Administrator Web Interface (AWI) go to Permissions > USB
  2. Under Bridged Devices click the Add New button
  3. Type the device's VendorID and ProductID into the appropriate fields.
  4. Reset the PCoIP Zero Client
  5. Connect to your virtual machine

After the device is bridged, install the recommended device driver to use features such as calibration, alignment and right-hand mouse options. If already installed, access your driver control panel to make any necessary changes.

Steps to calibrate the device can be found on the elo support site currently found at the following url.

Unsupported ELO devices such as the "Intellitouch+ 2515 USB" may function within a PCoIP session but not in a pre-session (PCoIP Zero Client OSD).

For firmware 4.0.x and earlier, connect the device after a PCoIP session has been established and consider the following environments.

  • In a workstation environment, should Windows not recognize the device natively, consider installing the elo device driver.
  • In a View environment where the operating system does not recognize the elo device, bridge the device as described in the steps above and test for functionality. If it still does not function, consider installing the appropriate ELO device driver and test again.
  • In a  HP Anyware environment where the operating system does not recognize the elo device, bridge the device as described in the steps above and test for functionality. If it still does not function, consider installing the appropriate ELO device driver and test again.

ELO models that are currently not supported with PCoIP are:

  • APR Accoustic pulse recognition
  • Intellitouch+ (may work in an established PCoIP session)
  • Projected Capacitive (ProCaP)
