RS-232C Communication
RS-232C Communication
When the projector connects to the computer by RS-232C communication, the 
projector can be controlled with RS-232C commands from the computer . 
For details of RS-232C commands, refer to RS-232C Communication / Network 
command table .
Connection
1. Turn off the projector and the computer.
2. Connect the projector's  CONTROL port and the computer's RS-232C port 
with a RS-232C cable (cross). Use the cable that fulfills the specification 
shown in figure 
3. Turn the computer on, and after the computer has started up turn the projector 
on.
4. Set the COMMUNICATION TYPE to OFF. ( OPTION menu - SERVICE - 
COMMUNICATION  in the Operating Guide )

3. Response code / Error code ("h" shows hexadecimal)
(1) 
 
ACK reply : 06h 
When the projector receives the Set, Increment, Decrement or Execute 
command correctly, the projector changes the setting data for the specified 
item by [Type], and it returns the code.
(2) 
 
NAK reply : 15h 
When the projector cannot understand the received command, the projector 
returns the error code. 
In such a case, check the sending code and send the same command again.
(3) 
 
Error reply : 1Ch + 0000h
When the projector cannot execute the received command for any reasons, 
the projector returns the error code.   
In such a case, check the sending code and the setting status of the projector .
(4) 
 
Data reply : 1Dh + xxxxh 
When the projector receives the GET command correctly, the projector returns 
the responce code and 2 bytes of data.
NOTE •  For connecting the projector to your devices, please read the 
manual for each devices, and connect them correctly with suitable cables. 
• Operation cannot be guaranteed when the projector receives an undefined 
command or data.
• Provide an interval of at least 40ms between the response code and any other 
code.
• The projector outputs test data when the power supply is switched ON, and 
when the lamp is lit. Ignore this data.
• Commands are not accepted during warm-up.
•  When the data length is greater than indicated by the data length code, the 
projector ignore the excess data code. Conversely when the data length is 
shorter than indicated by the data length code, the projector returns the error  code to the computer.

Command Control via the Network
When the projector connects network, the projector can be controlled with RS-
232C commands from the computer with web browser. 
For details of RS-232C commands, refer to RS-232C Communication / Network 
command table
.
Connection
1. Turn off the projector and the computer.
2. Connect the projector's LAN port and the computer's LAN port with a LAN

communication for 30 seconds after being established.
Authentication
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 “a572f60c”.
1)
  Select the projector.
2)
  Receive the random 8 bytes “a572f60c” from the projector.
3)
    B i n d   t h e   r a n d o m   8   b y t e s   “ a 5 7 2 f 6 0 c ”   a n d   t h e   a u t h e n t i c a t i o n   p a s s w o r d 
“password” and it becomes “a572f60cpassword”.
4)
    Digest this bind “a572f60cpassword” with MD5 algorithm.
 
It will be “e3d97429adffa11bce1f7275813d4bde”.
5)
    Add this “e3d97429adffa11bce1f7275813d4bde” 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.NOTE  • As  for  the  transmission  of  the  second  or  subsequent  commands, 
the authentication data can be omitted when the same connection.
