1.3.1.11 C-Touch Transfer Problems
Problem
Problems with transferring project data to or from C-Touch.
Solution
Assuming that you can connect to C-Touch, one cause of problems with transferring projects to
the C-Touch unit is that the memory has worn out. The Flash memory in C-Touch (units
manufactured prior to 2006) is only guaranteed for 100 rewrite cycles. It is unlikely that a C-Touch
would be reprogrammed this many times in a normal installation, but units used for training could
be. There is no fix for this.
If the transfer starts but does not complete, the problem may be with unreliable communications.
1.3.1.12 C-Touch Calibration
Problem
It is necessary to press next to a C-Touch component in order for it to operate
or
The start-up screens respond to touch, but after that it is not possible to control anything.
Cause
C-Touch needs to be re-calibrated.
Solution
There should be a calibration button somewhere in the C-Touch Project to start the calibration
process (this is a button with the
calibration
Special Function set).
If the calibration process is failing, it may be because your finger is too large. It is important to
press exactly on the X. To do this, use a device like a PDA stylus which has a small tip.
Do not
use anything sharp, as it will damage the screen.
If the calibration is way off, it may be necessary to reset the calibration. If your firmware is earlier
than version 1.6, then you can reset the calibration by either downloading the version 1.6 firmware
or :
·
Connect a PC to the C-Touch (via the download cable, or via C-Bus)
·
From the
Transfer
menu, select the
Connect to Touchscreen
menu item
·
From the
Transfer
menu, select the
Control Touchscreen | Reset Calibration
menu item
·
Disconnect from C-Touch
·
Calibrate as described above
1.3.1.13 C-Touch as a PCI
Problem
How do you use C-Touch as a PCI ?
Solution
C-Touch can be used as a PC Interface (PCI). It is necessary for any software that is using the
C-Touch as a PCI to set the handshaking lines correctly, as they are used to power the C-Touch
