Basic format
Transmission from the computer begins with STX, then the ID, command, parameter, and ETX are sent in this 
order. Add parameters according to the details of control.
Attention
No command can be sent or received for 10 to 60 seconds after the lamp starts lighting. Try sending any 
command after that period has elapsed.
When transmitting multiple commands, be sure to wait until 0.5 of a second has elapsed after receiving the 
response from the projector before sending the next command. When sending commands without parameters, a 
colon (:) is not necessary.
Note
When the wrong command is sent, the “ER401” or “ER402” status is sent from the projector to the personal 
computer.
Projector ID supported on the RS-232C interface is ZZ (ALL) and a group of 1 to 64 and 0A to 0Z.
The “STX” character code is 02 and the “ETX” character code is 03.
If a command is sent with a projector ID specified, the projector will return answer back only in the following 
cases:
If it coincides with the projector ID,
ID specification is ALL and VPS-SYSTEM is the master,
or ID specification is group and Group is the master.
Control commands
When controlling the projector from a computer, the following commands are available:

  Cleaning and replacement of air filter
If the air filter is blocked with too much dust, the inside of the projector will become hot and the temperature monitor 
(TEMP) indicator will flash and the power will turn off. The static electric mesh filter should be replaced and the 
metal mesh filter and brush inside the filter unit should be cleaned after approximately 2 000 hours of use, although 
this is a guide only and the actual time will vary depending on the operating conditions.
Procedure of cleaning
1.  Turn off the main power and remove the power plug from the receptacle.
Turn off the main power supply observing the procedure (How to turn “OFF” the power supply) on page 36 
and then remove the power plug. •
2.  Use a Phillips screwdriver to 
loosen the filter cleaning unit 
fixing screw at the front of the 
projector.
Insert your hand into the base of the air filter 
and pull the air filter forwards while removing the 
filter cleaning unit from the projector.
3.  Remove the static electric mesh 
filter from the filter cleaning unit.
Loosen the static electric mesh filter so that it 
can be removed, and then remove it. •

Information
Note
If cleaning cannot remove the dust completely, then it is a sign to replace the static electric mesh filter. Consult 
the dealer. In addition, when the lamp unit is replaced, also replace the static electric mesh filter.
Do not wash the static electric mesh filter with water. 
Use a neutral detergent to clean off any oil from the movable metal mesh filter.  •
•
•
7.  Install the movable metal mesh 
filter to the filter cleaning unit. 
When reassembling, align the edge of the 
movable metal mesh filter with position A.
Hook the movable metal mesh filter onto the 
gear and the rail.
The movable metal mesh filter will be set to the 
correct position after the set is installed and the 
power is turned on, so it can be installed in the 
middle position during reassembly without any 
problem. •

Install the air filter, and then install the filter 
cleaning unit by carrying out removal step 2 in 
reverse.
Attention
The air filter must be installed before using the 
projector. If the projector is used without the air filter 
installed, foreign particles and dust will get inside the 
projector and cause problems with operation.•

Precautions on lamp unit replacement
Be careful when handling a light source lamp. The lamp unit has high internal pressure. If improperly handled, 
failure might result.
A used lamp unit may burst if it is handled violently. For disposition of used lamps, request an industrial waste 
disposal contractor.
If you continue to use a lamp after the replacement time, the lamp may break.
Phillips screwdriver is necessary when replacing a lamp unit. Take care not to slip your hand when using a 
screwdriver.
Attention
A lamp unit is an optional part. Contact the dealer.
Replacement Lamp Unit model No.:  ET-LAD10000 (single bulb),  ET-LAD1000F (4 bulbs)
  Rating: 250 W
Other lamps than specified above cannot be used. Be sure to use the specified lamp.
Timing of lamp unit replacement
The lamp used for the light source has its due life. The life of light source lamp used in the main unit is 2 000 hours. 
However, it may happen that the lamp becomes dead (will not light) by the time of 2 000 hours depending on the 
characteristics of individual lamps and working conditions (lamps may reduce their life affected by the times of 
lighting and the intervals between previous lighting and next lighting). Therefore, it is strongly recommended for the 
user to keep a spare bulb.
If a lamp unit has not been replaced after 2 000 hours of operation have elapsed, the lamp will turn off
