Frequently Asked Questions

I cannot see the Henson camera on the test screen, only the feed from the computer’s built in webcam - what should I do?

If the laptop or computer has a built in webcam of its own then this, rather than the Henson camera, may initially be displayed on the test screen. To override this, the Henson camera needs to be selected in the Henson Options program.

Close all Henson software and run the Options program from the desktop shortcut.

Click ‘No’ to the opening message and click on the Video tab. The picture from the currently selected video device will be visible. To change it, click the dropdown box next to the video and select the other camera. The feed from the Henson camera should now be visible.

If there is no alternative camera listed in the dropdown then check that the USB cables from the rear of the Henson are both connected to the controlling computer (or a suitable powered USB hub).

The chinrest does not stop when I release the on-screen button using a touchscreen - what is wrong?

First of all, try operating the on-screen button using a standard mouse. If it works correctly then the touchscreen settings will need adjusting.

The issue may be that your touchscreen is not set up to replicate a mouse. This may be a setting on the touch screen software or in the Windows Control Panel.

Go to the Mouse section of Control Panel and turn off any right click events as these can be automatically triggered after one or two seconds of pressing and holding down a button.

If this does not solve the problem, then please contact your service agent for further information. You can find your local service agent via our Distributors page.

There appear to be a loss of communication between my computer and the Henson 9000 bowl...

If you can see the feed from the Henson camera on screen but are still getting messages about the Henson not being connected then check that the two USB cables from the rear of the Henson are both plugged into the computer (or a powered USB hub).

Open the Henson Options program from the Desktop shortcut, answer ‘No’ to the initial question and click on the Computer tab. There should be a device listed in the box shown below

Screen

It will not be called ‘Henson’ but if it is listed then check that the ‘Software only’ box is not ticked.

If it is then untick it and click the Save button.

I'm receiving a message about FT device I/O error - what's the issue?

This is usually caused by a conflict with another piece of equipment using the same USB chipset as the Henson. A common one is the IR receiver for the Thompson test chart which uses a very old USB driver and can cause issues.

The process to fix it is as follows:

  1. Disconnect your computer from the Internet.
  2. Open Control Panel from the Start menu.
  3. Click on Device Manager.
  4. Expand the Universal Serial Bus (USB) controllers option.
  5. Locate the two relevant USB devices.
  6. Unplug the Henson 7000 USB lead and one device should disappear
  7. Right click on the remaining device and select Uninstall.
  8. A message will appear – tick the box that says ‘Remove driver software from this computer’.
  9. Click the Search button on the toolbar at the top of the Device Manager window (it looks like a magnifying glass). The device will reappear.
  10. Repeat the uninstall process – each time ticking the “Remove driver software from this computer” box until the device does not reappear or you get a message stating that a driver cannot be found.
  11. Unplug the infrared (IR) receiver USB cable.
  12. Plug in the Henson USB cable. It may find a driver. If it does not then run the program CDM20824_Setup.exe from the C:\Henson7000\Install files\ folder. This is a USB driver and will prompt windows to sort out the new hardware.
  13. Once the driver has loaded run the Henson Options program, select the listed USB device in the Computer tab and click ‘Save’.
  14. Now plug in the IR receiver USB lead and it will use the updated Henson driver.
  15. You can now restore your Internet connection.

I think my Henson might be dead - what should I do?

Firstly check that the mains supply to the unit is OK. If it is then remove the mains cable from the socket on the underside of the unit and check the two fuses that are located in a drawer under the mains input connector. If the fuses are OK, then contact your service agent.

You can find your service agent via our Distributors page.

Remote support

In the event that you have any problems with your Henson, it is often possible for us to remote view your PC/control device in order to fix issues online.

To do this we require that the control device you are using is connected to the internet and has a remote access program running. You can download the remote client using this link. Once it is installed on your device, give the service technician the ID number and s/he will be able to view your machine and offer advice on the issue.
