Presets
When PAL is converted to NTSC or when NTSC is converted to
PAL, the aspect ratio of the display can be distorted. In order to
correct this distortion, six presets (shown in figure 5) are
available. Please refer to chapter three, RS-232 Control, for
information on choosing and using these presets.

device(s) (VCRs, monitors, projectors). The image should now
appear on the screen.
1 . Ensure that all devices are plugged in.
2 . Make sure that each device is receiving power. The TSC’s
front panel LEDs light if the device is receiving power and

device, turn on the Color Bars output, using an SIS
command, and disconnect the input signal.
5. Check that the appropriate output standard is selected.
6 . To test the system setup and output, substitute a video test
generator (VTG) for one of the video inputs. To use a
VTG, unplug the input and output devices and the TSC’s
power cord, replace the video source with a VTG, then
reconnect power cord to restore AC power.
