most accurate colors. If it does not, try the other choices and select the one that does. 
HDMI Black Level: This control compensates for incoming elevated black levels present 
in certain video signals. When you set it to Auto, the VX-2000d automatically determines 
the best setting according to the incoming video signal type. For some types of video, you 
may want to override the setting. Set it to 0 IRE if blacks appear elevated (dark gray). If 
blacks appear “crushed” (too dark), set it to 7 IRE. 
Background: Select Background from the Options menu, then press  or  to select 
the image background – solid blue, solid black or the Runco logo welcome screen. The 
Background appears when no incoming signal is present. 
Power Save: Select Power Save from the Options menu to access the power 
management features of the VX-2000d.
S-232C Port: When this option is set to On, the RS-232 port is always active and 
consuming power, even when the projector is in standby mode. When set to Off, the 
RS-232 port is inactive and does not consume power when the projector is in standby 
mode. 
 
When this option is set to On, the projector enters standby mode 
after 15 minutes of inactivity (no input signal). Five minutes before this is to occur, the 
message “Enter STANDBY mode in 5 min.” appears on-screen. This message updates 
to indicate the amount of time before the projector enters standby mode. 
When set to Off, the projector remains in the “power on” state regardless of the 
presence or absence of an input signal. 
 
Baud Rate: Select Baud Rate from the Options menu, then press the  or  button to 
select the projector’s RS-232 baud rate. This function is used to change the transfer rate 
of the RS-232 connection between the projector and the DHD Controller. The default 
setting is 9600 bps. Do not change it unless specifically instructed to do so by 
Runco Technical Support. 
Fan Mode: If the projector is being used in a high-altitude environment, use the Fan 
Mode control to prevent it from overheating. Set it to High Altitude (2) to run the fan at high 
speed; set it to Normal (1) to run the fan at normal speed.
Orientation: Refer to Adjusting the Picture Orientation on page 32. 
Factory Default: To reset all projector settings (including image settings) back to their 
factory defaults, choose 
Factory Default from the Options menu. When the confirmation 
message appears, select All Reset to perform the reset or Return to cancel. This action 
is not undoable. Proceed with caution! 
Always set this option to On. Doing otherwise may disrupt 
communication between the projector and DHD Controller. 
When you set the Auto Power Off function to Off, the LED function 
(refer to 
page 59) is automatically set to On. 
The Factory Default command does not reset the Lamp Timer or 
OSD Language setting.

Lamp Replacement
The lamp should be replaced when it reaches the end of its life (typically 2000 hours), or 
sooner if a noticeable degradation in brightness occurs. Contact your Runco dealer to 
obtain a replacement lamp.
1. Turn off the projector and unplug the power cord. Allow the projector to cool down for 
approximately 45 minutes prior to removing the lamp assembly for replacement.
2. Using a Phillips screwdriver, loosen the two Lamp 
Cover screws on the side of the projector and 
remove the cover.
 
 
 
 
 
 
 
 
 
3. Remove the three Phillips round-head lamp 
assembly mounting screws. These are identified by 
arrows pointing to them on the lamp housing.
4. Grasp the lamp assembly handle and pull gently, removing the lamp module from the 
projector housing.
5. Install the new lamp module. Secure it in place with the three screws that you 
removed in Step 3.
6. Replace the lamp cover and re-tighten the two Lamp Cover screws.
7. Re-connect the AC power cord to the projector.
8. Reset the Lamp Hour counter by doing either of the following: 
On the projector rear-panel keypad (see Figure 2-6), press and hold the 
ENTER, DOWN and RIGHT buttons simultaneously. Then, press the ON button. 
On the DHD Controller front panel (see Figure 2-3), while pressing and holding 
the ENTER button, press the POWER () button. 
When you do, “LAMP 0000H” appears on-screen to confirm the counter reset. 
5. Maintenance and Troubleshooting
Always reset the Lamp Hour counter when you replace the lamp. 
Do this only if you have just installed a new lamp. This will ensure 
that number of hours logged on the lamp is accurate.

6.1 
RS-232 Connection 
and Port Configuration
To interface the DHD Controller with a home theater automation/control system or a PC 
running terminal emulation software, connect it to your control system or PC as shown in 
Figure 3-11. 
Configure the RS-232 controller or PC serial port as follows: no parity, 8 data bits, 1 stop 
bit and no flow control. Set the baud rate to 19200, to match that of the DHD Controller 
RS-232 port. 
6.2 
Serial Command 
Syntax
Serial commands to the DHD Controller take the following form:
 Commands are not case-sensitive. 
 For a single command that takes no parameters, type the command followed by a 
carriage return; for example, to set the aspect ratio to Letterbox, type 
LETTERBOX
 . 
 For a single command that takes a parameter, type the command, a space or a 
comma and the desired value followed by a carriage return; for example, to set the 
brightness to -10, type BRIGHTNESS
 -10  or 
BRIGHTNESS,-10
 . 
 You can also send a string of multiple commands on a single line, separated by 
commas. For example, COMPOSITE,BRIGHTNESS
 100,ANAMORPHIC  
switches to the Composite video input, sets the brightness to 100 and sets the aspect 
ratio to Anamorphic. Command strings can be up to 255 characters long. 
 
Table 6-1 lists the RS-232 command set. The “Parameter (min/max)” column shows the 
valid parameter ranges, or “NA” for commands that take no parameters. 
When you enter a valid command, the DHD Controller executes it and acknowledges it 
with a plus sign on the command line (+ >). When you enter an invalid command – one 
that is misspelled or followed by values outside the valid range for that command – the 
DHD Controller ignores it and returns a minus sign (- >). 
 
6. Serial Communications
Avoid combining the ON or POWER 1 commands with other commands 
on a single line. After sending ON or POWER 1, allow at least 15 
seconds for the DHD
 Controller to power up. Once it does, it will accept 
and properly execute multiple serial commands.
