Digital Projection LIGHTNING 10sx And LIGHTNING 15sx User Manual

							The function buttons, located at the bottom of the remote control, allow you to
adjust (where applicable) the brightness, contrast, sharpness, saturation, hue, 
position, size, pixel resolution, pixel phase and colour temperature of the channel
currently being displayed. If a motorised lens mount is fitted to the projector the
focus and horizontal/vertical position of the displayed image may also be adjusted
using the ‘LENS’ button.
Although it is not a necessity, it is recommended that the On Screen Display should
be ON before adjusting any of the channel parameters as you can then be sure
which function (if any) has been activated.
When the OSD in ON, pressing a function button will bring up its icon and a scalar
bar indicating the current setting. This value can then be adjusted using the cursor
keys. The current channel is displayed in the background so that you can see the
changes in the image as it is adjusted. All of the functions operate a Hold Live 
system which deactivates the function after 5 seconds if no further buttons are
pressed (or 5 seconds after the last adjustment was made).
The cursor keys are repeat action buttons and will keep changing a setting until
released or the parameter limits have been reached.
After making your adjustments to the channel image you can toggle between the
original and revised parameter settings using the PREV (previous) and REV
(revised) buttons on the remote control. To save your new settings press the SAVE
button, the save icon will appear for 5 seconds along with a message stating,
Channel XX updated successfully (where XX is the channel number currently
being displayed).
As factory preset channels are mapped to specific inputs it is not possible to change
a factory preset channels input. Should you wish to use a modified version of these
channels using a different physical input the modifications must be saved a new
channel using Channel Set Up.

							BRI, SAT, SHARP, CON, HUE
These function buttons are used to select and adjust the image parameters. When
selected their associated icon and a numerical field will appear. The settings are
adjusted using the cursor keys with the ñand ðcursors increasing the value and
the ïand òcursors decreasing it.
POS
Sets the horizontal and vertical position of the image. Pressing a cursor key will
move the image in that direction.
SIZE
Sets the horizontal and vertical image size. The width is increased with the ðcursor
and decreased with the ïcursor. The height can be increased using the ñcursor
and decreased using the òcursor.
PIXEL
This function is used to adjust the number of horizontal pixels being sampled in the
incoming image and is only relevant for channels configured for computers. The ñ
and ðcursors can be used to increase the value or the ïand òcursors can be used
to decrease it.
PHASE
This function is only relevant to computer channels and is used to adjust  the phase
of the pixel clock with the ñand ðcursors increasing the value and the ïand ò
cursors decreasing it.
COL
This function adjusts the colour temperature setting in steps of 100° (or 500°) from
3000° to 9000°. When this function is selected the colour temperature icon will
appear along with a numerical field showing the current temperature. The ñand ð
cursors can be used to increase the value or the ïand òcursors can be used to
decrease it. Holding down a cursor key for up to 5 seconds will automatically step
100° per second, after 5 seconds the value will change in 500° steps.

							LENS SHIFT
Adjusts the horizontal and vertical position of the displayed image relative to the
projector. To select Lens Shift press LENS until the Lens Shift dialogue box
appears on the screen. The horizontal shift can then be adjusted using the ïand ð
cursors. The vertical shift (rising/falling front) is adjusted by using the ñand ò
cursors.
Vertical and horizontal shift can be used in combination, however the extent of their
individual ranges will be reduced depending on the amount of shift used i.e. vertical
shift is maximised when horizontal shift is centred and vice versa. When the extent
of the range reaches its limit, it is possible that there will be a slight distortion of the
lens position which may result in additional flare. If this position is reached, reduce
the lens shift until the distortion is removed.
ZOOM
The LENS button on the remote control also has a Zoom option.
E-ZOOM
A means of setting a window, centred within the DMD™, of independently
adjustable height and width. The entire image will be displayed inside the window
and the area of the DMD™ outside the window will be black (see C—28).
FOCUS
To select Focus press LENS until the Focus dialogue box appears on the screen and
then make any adjustments using the ñand òcursor buttons.
Focus adjustment starts very slowly and may not be immediately obvious, therefore
the cursor buttons should be held down until the focus visibly changes. To achieve
optimum focus it may be necessary to repeat the adjustment a couple of times until
the operation of the feature feels comfortable to use.

Multiple projectors are used to produce a brighter image, to join up two or more
images or to display two or more images side by side.
When using multiple projectors it may be necessary to control all projectors at once,
or to operate an individual projector. This is achieved through the use of the Infra-
red remote control or a computer.
Each projector has its own unique address which is set using the remote control or a
computer (see Set Projector Address, C—35 & Computer Control, opposite). The
remote control can operate up to 32 projectors and a computer is capable of 
operating up to 127.
The A button on the remote control is used to program the remote control unit to
send a command to all operating projectors, or to an individual projector, see the 
examples below.
To activate only projector #1:
1.  Press A twice.
2.  Press 1.
3.  Use control buttons to operate projector #1.
To address all of the projectors:
1.  Press A twice.
2.  Press 0 (zero is the global address).
3.  Use control buttons to operate all projectors.
You must press the A button twice within three seconds in order for the function
to be recognised and the function will be automatically de-selected if you do not
issue any commands within 10 seconds.
All of the remote commands, apart from A, can be global or individual. If you use
the remote for an individual projector, you will need to make sure that only that
projector receives the command.

							To control the projector by computer, it is necessary to set up certain parameters
within the control device and then connect the projector via a suitable cable to the
computer (see D—19, Cables & Connections). The cable should be plugged into the
‘Computer In’ port on the projector and extra projectors may be connected, in
‘Daisy Chain’ fashion, using the ‘Computer Out’ port. A maximum number of 127
individually addressed projectors may be connected in this way.
The projector and computer send data to each other at RS232 levels. The
following protocol must be specified for the computer’s serial port:-
Data Rate:19,200 baud
Data bits:8
Stop bits:1
Parity:None
Handshake:None
The Data Rate can be changed to 9,600. For more information contact your dealer.
Data transfer to and from the projector is made up as a series of ASCII coded 
hexadecimal characters formed into message packets using the structure below:-
Address   Header   Data Length   Data   Checksum   Delimiter
AddressProjector address (01 - 127) consisting of two characters.
HeaderCommand instruction consisting of two characters.
Data LengthA two character number representing the data string length.
DataVariable length string of characters.
ChecksumTwo least significant digits of sum generated by adding all 
previous pairs of characters.
DelimiterCarriage return.
It is recommended that the checksum calculation is used, however, it can be avoided
by substituting two lower case ‘x’s instead of two calculated digits. This tells the
projector to ignore the checksum and treat the message as being correctly received.

							Using an appropriate RS232 interface (see D—19, Cables & Connections) the 
projector can be used in conjunction with a third party switching device. Currently
‘Extron System 8’ and ‘Extron System 10’ are compatible with the projector.
The projector and external switching device communicate at RS232 levels using the
following protocols:-
Data Rate:9,600 baud
Data bits:8
Stop bits:1
Parity:None
Handshake:None
At present, an external switcher will allow you to control the lamp power, picture
mute and channel change functions. Messages transferred to and from the projector
are made up as a series of ASCII coded hexadecimal characters formed into 
message packets using the structure below:-
Header   Data Length   Data   Checksum
HeaderRepresents data type according to the table below.
Data LengthWill indicate the amount of variable length data to follow, in 
bytes, not including the checksum.
DataVariable length string of characters.
ChecksumA checksum of XX will indicate that the checksum should be
ignored and the message treated as correctly received.
Header Message Data Meaning
04 Lamp Power XXChange lamp power to specified value. 
00 = minimum power and FF = maximum.
07 Picture Unmute - Unmutes the Picture.
