22.6 Checking the Touch Pad

The touch pad on the TE 530 and 530B keypads functions also for the single-processor control

in connection with the Windows operating system of a dual-processor control and as of software

version smarT.NC!

This touch pad is not connected to the MC via keypad connector X45 but with a USB cable to

MC connector X141.

If the touch pad does not function, carry out the following test to find out if the touch pad itself

or the interface on the control is defective:

Try the second USB connector X142 on the control.

If a new mouse or touch pad is connected, it functions only after the control has been

switched off and on again.

Try a commercially available mouse on the USB connectors of the control (the mouse should

function on a Windows 2000 PC).

If necessary, you can also extend the USB cable of the touch pad, connect it to a laptop and

test the functioning (the laptop must be equipped with a Windows operating system with the

corresponding mouse driver).

As the touch pad is managed by Windows, there are also the corresponding Windows

settings. --> "My computer/Control Panel/Mouse..."
