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 (
18).
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 fulfi lls the specifi cation 
shown in fi gure 
3. Turn the computer on, and after the computer has started up turn the projector 
on.
4. Set the COMMUNICATION TYPE to OFF in the COMMUNICATION menu of the 
OPTION - SERVICE menu.

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.

[TCP #23]
1. Command format
Same as RS-232C communication, refer to RS-232C Communicaton command format.
2. Response code / Error code ("h" shows hexadecimal)
Four of the response / error code used for TCP#23 are the same as RS-232C 
Communication (1)~(4). One authentication error reply (5) is added.
(1)  ACK reply : 06h 
Refer to RS-232C communication
 (11).
(2)  NAK reply : 15h 
Refer to RS-232C communication
 (11).
(3)  Error reply : 1Ch + 0000h 
Refer to RS-232C communication
 (11).
(4)  Data reply : 1Dh + xxxxh 
Refer to RS-232C communication
 (11).
(5)  Authentication error reply : 1Fh + 0400h 
When authentication error occurred, the projector returns the error code.
[TCP #9715]
1. Command format
The commands some datum are added to the head and the end of the ones of 
TCP#9715 are used.

[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).
NOTE • 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.

NOTE • As for the transmission of the second or subsequent commands, the 
authentication data can be omitted when the same connection.
2. Response code / Error code ("h" shows hexadecimal)
The connection ID is attached for the TCP#23's response / error codes are 
used. The connection ID is same as the sending command format.
(1) ACK reply:  06h + ××h   (××h : connection ID)
(2) NAK reply:  15h + ××h
(3) Error reply:  1Ch + 0000h + ××h
(4) Data reply:  1Dh + xxxxh + ××h
(5) Authentication error reply:  1Fh + 0400h + ××h
(6)  Projector busy reply:  1Fh + ××××h + ××h 
When the projector is too busy to receives the command ,the projector 
returens the error code. 
In such a case, check the sending code and send the same command again.
Automatic Connection Break
The TCP connection will be automatically disconnected after there is no 
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 connected to a LAN, a random 8 bytes will be returned 
if authentication is enabled. Bind this received 8 bytes and the authentication 
password, and digest the data with the MD5 algorithm, and add it in front of the 
commands to send. 
Following is a sample of authentication process. 
  Authentication password: password (example) 
  Random 8 bytes: a572f60c (example)
1)  Select a projector and receive the random 8 bytes from the projector. 
  “a572f60c”
2)  Bind the random 8 bytes and the authentication password. 
  “a572f60cpassword”
3)  Digest this bound with MD5 algorithm. 
  “e3d97429adffa11bce1f7275813d4bde”
4)  Add this code in front of the commands and send the data. 
  “e3d97429adffa11bce1f7275813d4bde” + [command].
5)  When the sent data is correct, the command will be performed and the reply 
data will be returned. Otherwise, an authentication error will be returned.
