Knoll Systems Hdp420 Projector User Manual

							  21  
When Autosource is not checked, the projector defaults to Component initially, then defaults to 
whatever the last active source was when the projector was powered down. To display another 
source, you must manually select one by pressing the Source button on the remote or keypad.  
This cycles through all the sources that are selected in the Source Enable menu. 
 
The Source 1, 2, and 3 menus in the Sources menu allow  Sources   Source Enable  
you to assign a source to the Source 1, 2, and 3 buttons 
on the remote. The Source 4 menu selection would  
apply to the Custom key if that option is chosen in the  
Custom key menu, see page 22. 
 
To use the SCART RGB source, you must first select 
it in the Source Enable menu (the projector cannot 
automatically detect this source). Enabling 
SCART will disable Component and Composite  
sources. 
 
System>OSD Offset: System>OSD Offset: allows you to adjust the 
position of the OSD. By default, the menus are postponed in the 
upper left hand corner of the displayed image and the messages are 
postponed in the lower left hand corner. Adjust the offset to move 
these items more to the right and middle of the display.  
Rear: reverses the image so you can project from behind a 
translucent screen.       
Ceiling: turns the image upside down for ceiling-mounted projection. 
Auto Ceiling: uses an internal sensor to automatically turn  
on ceiling mount mode if the projector is inverted.  
High Power: maximizes the light output of the lamp.  
Auto Power: when AutoPower is checked, the projector automatically goes into the startup state 
after the projector receives power. This allows control of ceiling mounted projectors with a wall 
power switch. 
Display Messages: displays status messages (such as “Searching”) in the lower-left corner of 
the screen.  
Translucent OSD: makes the menus translucent. This prevents the image from being completely 
covered by the menus while you are making image adjustments.  
Sleep Timer: automatically turns off the projector after 4 hours.  
Power Save: automatically turns the lamp off after no signals are detected for 20 minutes. After 
10 additional minutes with no signal, the projector powers down. If an active signal is received 
before the projector powers down, the image is displayed. 
 
 
 
Startup Logo: allows you to display a blank screen   
instead of the default screen at startup. 
 
   
  
.    
 
Blank Screen: determines what color is displayed when 
you select Blank Screen in the Startup Logo menu 
and when no source is displayed. 
 
 
 
 
  
						

							22 
Language: allows you to select a language for the onscreen display.

  key on the remote, allowing you to quickly and easily use the effect. \
Highlight an effect and 
  press Select to choose a different one. 
 
• Blank Screen: displays a solid blank image. 
 
• Freeze: takes a snapshot of the projected image. If you’re watching video, the source video 
   continues to run but the image is frozen. 
 
• Source Info: the default effect. It opens a window with projector and source information. 
 
• Service Info: opens the Service info window. 
 
• Source 4: selects source 4 (by default, Source 4 is the Composite input). This gives you four 
  direct source options on the remote. See page 20. 
 
Service: To use these features, highlight them and press 
Select. 
 
Factory Reset: restores all settings to their default. 
   
Reset Lamp Hours: resets the lamp hours used in the 
Service Info menu to zero. Do this only after changing the 
lamp. 
 
Test Pattern: displays a test pattern. To display test patterns, first you must assign Blank Screen 
to the Custom key (page 17), then click the Test pattern check box in the Service menu to turn 
the option on, exit the menus, then press the Custom button on the remote. To select the 
patterns, use the up/down arrows on the remote or keypad. To exit the test patterns press  
the Custom button. 
 
Blue Only: turns off the Red and Green  
portions of the input, allowing you to properly  
adjust the color balance with a SMPTE color  
bar pattern. 
 
HDMI DDC: turns off the EDID extension. 
Some graphic cards cannot recognize the 
projector’s EDID. Uncheck this box if you  
have trouble using HDMI or DVI sources. 
Service Info: provides information about the  
projector’s software, serial number and lamp.

Maintenance 
Cleaning the lens      
1 Apply a non-abrasive camera lens cleaner to a 
   soft, dry cloth. 
• Avoid using an excessive amount of cleaner,  
  and don’t apply the cleaner directly to the lens.  
  Abrasive cleaners, solvents or other harsh 
  chemicals might scratch the lens. 
2 Lightly wipe the cleaning cloth over the lens in a  
   circular motion. 
         Lamp hours used 
 
 
Replacing the projection lamp 
The lamp hour’s timer in the Service Info menu counts the                    wait 60 minutes  
number of hours the lamp has been in use. Twenty hours 
before the lamp life expires a message appears on the  
screen at startup indicating that you should change the  
lamp. The LED on the top of the projector also blinks red  turn off and unplug the projector 
twice to indicate that the lamp should be changed. Use only      
a replacement lamp with the same type and rating as the 
original lamp. Lamps can be purchased direct from Knoll or 
the dealer that sold the projector. 
 
1 Turn off the projector and unplug the power cord. 
   If ceiling mounted, disconnect all cables and 
   detach the projector from the ceiling mount.   
 
2  Wait 60 minutes to allow the projector to 
    cool thoroughly. 
 
3. Turn the projector upside down on a 
    soft cloth so that the lamp door is 
    facing you. Remove the base or ceiling  
    mount plate, if attached, by removing the three screws. 
 
4.Loosen the two captive screws on the lamp door and lift it off. 
 
5. Loosen the two captive screws that attach the lamp housing 
    to the projector. 
 
6.   Carefully remove the lamp housing. Dispose of the lamp in 
      an environmentally proper way. 
            
WARNING: 
To avoid burns, allow the projector to cool for at least 60 minutes before you replace the lamp. 
Be extremely careful when removing the lamp housing. In the unlikely event that the bulb  
ruptures, small glass fragments may be generated.                     
 
The lamp housing is designed to contain these fragments, but use caution when removing the   
lamp housing. Before replacing the lamp, clean the lamp compartment and dispose of cleaning 
materials. Make sure to wash your hands after lamp replacement. This product has a lamp, which 
contains a very small amount of mercury. Dispose of it as required by local, state or federal 
ordinances and regulations. For more information see www.eiae.org.

Remote control discrete codes 
 
You can use these codes to program another remote to learn the projector’s remote functions. 
To activate discrete mode, press and hold the Custom button on the remote for 10 seconds. The 
backlight blinks twice when discrete mode is entered. The remote buttons are now remapped to 
new functions as listed below. To return to normal remote mode, press and hold the Custom 
button on the remote for 10 seconds. The remote also returns to normal m\

RS232 COMMAND FORMAT 
All commands consist of 3 alpha characters followed by a request, all enclosed in parentheses. 
The request can be a read request (indicated by a “?”) or a write request (indicated by 1 to 4 
ASCII digits). 
 
A read request format (AAA?) where 
 
  (  starts the command 
  AAA denotes the command 
  ? denotes the read request 
  )  ends the command 
 
A read command returns the range and the current setting, for example: 
 
 
 Function   Command   Response 
 
 Brightness   (BRT?)    (0-22,10) 
 Lamp hours   (LMP?)    0-9999,421) 
 
 
 
A write request example: (AAA####) where 
 
   ( starts the command 
   AAA  denotes the command 
   #### denotes the value to be written (leading in zeros not necessary) 
   ) ends the command  
 
 
Some commands have ranges, while others are absolute. If a number greater than the maximum 
range is received, it is automatically set to the maximum number for that function. If a command 
is received that is not understood, a “?” is returned. With absolute settings, “0” is off, 1-999 is on. 
The one exception is the Power command, where 0 is off and 1 is on. 
 
    
Function  Command  Response 
 
  Brightness  (BRT10)  Sets brightness to 10 
  Power   (PWR0)   Turns power off 
  Power   (PWR1)   Turns power on 
  Power   (PWR9999)  ?
