In Autosync mode, the SuperView requires an external host sync source be
connected at the B
connected at the B
ACKGROUND
I
NPUT
connector. The output of the SuperView
will match the timing and format of the external source. Thus with a
1280x 1024 PC, running at 65 kHz and 60 Hz, and a separate Horizontal and
Vertical drive sync format (RGBHV), the output of the SuperView will also be
1280x 1024, 65kHz and 60Hz, with separate Horizontal and Vertical sync.

Autosync is not the default mode of the SuperView. To set the unit to Autosync
using the serial port, type the HOST AUTO command. To set the mode using the
front panel, press the O
using the serial port, type the HOST AUTO command. To set the mode using the
front panel, press the O
UTPUT
button and navigate to the Output Sync menu
where you can set the mode to Auto.
Autosync mode has two different states. If the background signal is connected
and visible, this is referred to as background Autosync mode. If the signal is
connected but turned off, then this is referred to as genlock Autosync mode; the
output characteristics of the signal are provided even though the signal is not
visible. The two modes are controlled with the BackGround ON|OFF
command.

When the SuperView sees a new host computer video timing, it checks to see if
the signal’s characteristics are in its list of stored timings. (See “Host List” on
page 49.) If the characteristics are not in its list, it uses an internal algorithm to
estimate the timing of the video, and configures itself appropriately. This
procedure is adequate for most applications and timings, but for greater
accuracy you can fine-tune and store the settings. This fine-tuning is done either
by feeding the exact timing numbers (using the HostTiming command) or
by an interactive adjustment procedure through the front panel or the serial port.

To adjust timing interactively through the serial port use the
HostInteractive
command. Adjusting the timing usually takes less than
five minutes. Refer to the HostInteractive command on page 49 for more
details.
