RS 232 AND LAN CONTROL

RS 232
You may control and monitor the projector remotely through the serial
RS232 control interface.
Two RS232 protocols are employed. A simple instruction set (SIS)
ASCII protocol gives access to the most frequently used commands.
In addition, a binary protocol is available where each command is a
series of 32 bytes in one packet. The protocols allow for both SET
and GET operations. To utilize GET operations the host needs a
routine for receiving and interpreting incoming packets. SET-
operations are used to force the projector into different modes, like
setting brightness and contrast, switching between sources, etc.
A separate document "RS-232 and LAN communication protocol and
command set" is available that describes the communications
parameters and operational codes in detail.
LAN
The projector can be controlled and monitored through the LAN
connector as an alternative to RS232.
LAN control is available either through an embedded web page for the
most frequently used commands or using the same command set as
for RS232 for full access to all system controls.
NOTE! THE PROJECTOR IS CONFIGURED WITH A DEFAULT IP
ADDRESS. SEE THE SYSTEM INFORMATION AVAILABLE
THROUGH THE MENU SYSTEM OR REMOTE CONTROL FOR THE
ACTUAL IP-ADDRESS.
Detailed descriptions of configuration, use and command set is
described in a separate document "RS-232 and LAN communication
protocol and command set".
You may consider using the LAN interface as a means of theft-
detection. When the projector is removed, the LAN will be
disconnected; this may be detected over the local area network and
could be used to trigger an alarm.

TROUBLE SHOOTING

NO IMAGE
No connection: Check if all connections are properly made.
Source off: Check if the equipment is powered on.
Lamp dead: The lamp may need replacement. Check the LAMP TIME
in the UTILITIES sub menu.
Source hibernated: Engage the source to display and activate image.
Notebook external screen: Different notebook PC's use different
combinations of keystrokes to enable the external graphics port.
Source scan off: Check SOURCE SCAN in the SET UP sub menu. If
setting is OFF, the projector will not search for the next active source,
but will remain with the current source selected.
No lens: Check if lens is attached properly.
Shutter engaged: Check if the shutter is engaged.
Lens cap: check if the lens cap is off!
DARK IMAGE
Old, worn lamp: The lamp may need replacement. Check the LAMP
TIME in the UTILITIES sub menu.
Low BRIGHTNESS and CONTRAST settings: Press AUTO or use
the menu system, PICTURE sub menu for CONTRAST and
BRIGHTNESS adjustment.
FLICKERING IMAGE
Bad lamp: Replace the lamp. Check the LAMP TIME in the UTILITIES
sub menu.
UNSHARP IMAGE
Keystone correction may have been activated inadvertently,
compressing parts of the image that affect the display of fine-line
graphics, text and other images of high resolution.
Source resolution is different from projectors native resolution:
The projector will automatically scale and resize the input format to its
native resolution. Use a different scaling factor in the PICTURE sub
menu, ASPECT. You may also adjust the SHARPNESS.
