Operation, cont’d
AUTO SW (auto switch mode) —
Disabled — Use manual input selection via the front panel
Input Selection button or through the RS-232 connector.
Enabled — The input with a video signal present is
selected automatically. If video is present on both inputs,
input 2 is selected.
SERR REM (serration pulse removal) —
Disabled — Serration pulses are passed along with the
vertical sync pulse.
Enabled — Serration pulses are removed from the output
vertical sync pulse.
SPLIT SCR (split screen) —
Disabled — Split screen is disabled.
Enabled — Split screen (demo mode) displays the selected
interlaced video on the left side of the screen and the line
doubled video on the right half of the screen.
STILL (still mode) —
Disabled — Selects motion compensation mode, which
optimizes motion video such as from DVD and laserdisc
players.
Enabled — Selects still mode, which enhances still video
such as text, for easier reading.
VGA (VGA mode) —
Disabled — The number of horizontal output lines is twice
the number of input lines per screen scan. For NTSC, the
number of horizontal lines, normally 262.5, doubles to 525.
For PAL, the number of horizontal lines, normally 312.5,
doubles to 625.
Enabled — The active vertical resolution becomes 480 non-
interlaced horizontal lines, regardless of input.
H+ (horizontal sync polarity pulse) —
Disabled — The horizontal sync polarity will be negative.
Enabled — The horizontal sync polarity will be positive.
V+ (vertical sync polarity pulse) —
Disabled — The vertical sync polarity will be negative.
Enabled — The vertical sync polarity will be positive.

X MODE (executive mode) —
Disabled — All front panel operations are enabled.
Enabled — Front panel picture control adjustments (Color,
Tint, Contrast, and H Shift) are locked out. The front panel
Min and Max LEDs light together to indicate that executive
mode is enabled.
13 H/HV/SOG switch — This switch selects the sync signal that is
output on the output H BNC.
H position — Horizontal sync only is output on the H BNC.
Vertical sync is output on the V BNC. Use this switch position
for RGBHV video.
HV position — Composite (horizontal and vertical) sync is
output on the H BNC. Use this switch position for RGBS video.
SOG position — Sync is on the green signal and is not output
on the H BNC. Use this switch position for RGsB video.
Operation
Plug in all system components and turn on the input devices
(DVD player, laserdisc player, DSS receiver, etc.) and the output
device. Set the input devices to output video in accordance with
their own operating instructions. The image should appear on
the screen.
For each input, adjust the picture controls (Color, Tint, Contrast,
and H Shift) for the best possible image.
Troubleshooting
If the image does not appear
1 . Ensure that all devices are plugged in and powered on.
The Lanciaxi is receiving power if the front panel power
LED is lit.
2 . Ensure that an active input is selected on the Lanciaxi.
3 . Ensure that the H/HV/SOG switch is in the correct
position for the video output.
4 . Ensure that the horizontal and vertical sync DIP switches
are in the correct position.
5 . Check the cabling and make corrections as necessary.
6 . Call the Extron customer support hotline if necessary.
