Command Format
Command formats differ among the different communication ports.
●  
TCP #23 
You can use the RS-232C commands without any changes. The reply data 
format is the same as the RS-232C commands. However, the following reply 
will be sent back in the event of authentication failure when authentication is 
enabled.
HeaderData lengthRS-232C commandCheck sumConnection ID

RS-232C commands  →   RS-232C commands that start with 0xBE 0xEF  
(3 bytes)
Check Sum  →   This is the value to make zero on the addition of the 
lower 8 bits from the header to the checksum.
Connection ID  →   Random value from 0 to 255 (This value is attached 
to the reply data)
●  
TCP #9715
Send Data format
The following formatting is added to the header (0x0), Data length (0x0D), 
Checksum (1byte) and Connection ID (1 byte) of the RS-232C commands.

Automatic Connection Break
The TCP connection will be automatically disconnected after there is no 
communication for 30 seconds after being established.
The projector does not accept commands without authentication success 
when authentication is enabled. The projector uses a challenge response type 
authentication with an MD5 (Message Digest 5) algorithm.
When the projector is using a LAN, a random 8 bytes will be returned if 
authentication is enabled. Bind this received 8 bytes and the Authentication 
Password and digest this data with the MD5 algorithm and add this in front of the 
commands to send.
Following is a sample if the Authentication Password is set to “password” and the 
random 8 bytes are “a57f60c”.
Authentication
) Select the projector.
) Receive the random 8 bytes “a57f60c” from the projector.
3)  Bind the random 8 bytes “a572f60c” and the Authentication Password 
“password” and it becomes “a57f60cpassword”.
4)  Digest this bind “a572f60cpassword” with MD5 algorithm. 
It will be “e3d97429adffa11bce1f7275813d4bde”.
5)  
Add this “e3d9749adffabcef77583d4bde” in front of the commands 
and send the data. 
Send “e3d97429adffa11bce1f7275813d4bde”+command.
6)   When the sending data is correct, the command will be performed and the \
reply data will be returned. Otherwise, an authentication error will be returned.
• As for the transmission of the second or subsequent commands, the 
authentication data can be omitted when the same connection.

Maintenance
A lamp has finite product life. Using the lamp for long periods of time could cause 
the pictures darker or the color tone poor. Note that each lamp has a different 
lifetime, and some may burst or burn out soon after you start using them\
. 
Preparation of a new lamp and early replacement are recommended. To prepare 
a new lamp, contact ViewSonic and tell the lamp type number.
Lamp
Type number = RLC-038     (DT0087)
.Turn the projector off, and unplug the power cord. 
Allow the projector to cool for at least 45 minutes.
.Prepare a new lamp.  
If the projector is mounted on a ceiling, or if the lamp 
has broken, also ask the dealer to replace the lamp.
3.Loosen the screw (marked by arrow) of the lamp 
cover and then slide the lamp cover to the side to 
remove it.
4.Loosen the 3 screws (marked by arrow) of the 
lamp, and slowly pick up the lamp by the handles.
5.Insert the new lamp, and retighten firmly the 
3 screws of the lamp that are loosened in the 
previous process to lock it in place.
6.Slide the lamp cover back in place and firmly 
fasten the screw of the lamp cover.
7.Turn the projector on and reset the lamp time using

Lamp warning
Lamp (continued)
 HIGH VOLTAGE HIGH TEMPERATURE HIGH PRESSURE
►The projector uses a high-pressure mercury glass lamp. The 
lamp can break with a loud bang, or burn out, if jolted or scratched, handled 
while hot, or worn over time. Note that each lamp has a different lifetime, and 
some may burst or burn out soon after you start using them. In addition, when 
the bulb bursts, it is possible for shards of glass to fly into the lamp housing, and 
for gas containing mercury to escape from the projector’s vent holes.
►About disposal of a lamp: This product contains a mercury lamp; do not put 
it in a trash. Dispose of it in accordance with environmental laws.
• For lamp recycling, go to www.lamprecycle.org (in the US).
• For product disposal, contact your local government agency  
or www.eiae.org (in the US) or www.epsc.ca (in Canada).
For more information, call ViewSonic.
WARNING
• If the lamp should break (it will make a loud bang when it does), 
unplug the power cord from the outlet, and make sure to request a replacement lamp from your local dealer. Note that shards of glass could damage the projector’s internals, or cause injury during handling, so please do not try to clean the projector or replace the lamp yourself\
.• If the lamp should break (it will make a loud bang when it does), ventilate the room well, and make sure not to breathe the gas that comes out of the projector vents, or get it in your eyes or mouth.• Before replacing the lamp, turn the projector off and unplug the power cord, then wait at least 45 minutes for the lamp to cool sufficiently . Handling the lamp while hot can cause burns, as well as damaging the lamp.
• Never unscrew except the appointed (marked by an arrow) screws.
• Do not open the lamp cover while the projector is suspended from a ceiling. This is dangerous, since if the lamp’s bulb has broken, the shards will fall out when the cover is opened. In addition, working in high places is dangerous, so ask your local dealer to have the lamp replaced even if the bulb is not broken.• Do not use the projector with the lamp cover removed. At the lamp replacing, make sure that the screws are screwed in firmly. Loose screws could result in damage or injury.
• Use only the lamp of the specified type.
• If the lamp breaks soon after the first time it is used, it is possible that there are electrical problems elsewhere besides the lamp. If this happens, contact your local dealer or a service representative.• Handle with care: jolting or scratching could cause the lamp bulb to bur\
st during use.• Using the lamp for long periods of time, could cause it dark, not to light up or to burst. When the pictures appear dark, or when the color tone is poor, please replace the lamp as soon as possible. Do not use old (used) lamps; this is a cause of breakage. 
Disconnect the plug from the power outlet
