4. 1. 6. Basic format
Transmission from the computer starts with STX, then the ID, command, parameter, and ETX are sent in this order.
Add parameters according to the details of control.
1. Basic control command (without parameter)
2. Basic control command (with parameters)
3. Basic control command (with sub command)
4. Operation
Specifies the method of processing the value specified by parameters.
Description
Sets the value specified by the parameter.
Adds the value specified by the parameter to the current value.
Sets the value specified by the parameter.
Adds the value specified by the parameter to the current value.
5. Sign
Specifies positive or negative of the value specified by parameters.
Description
The value specified by the parameter is a positive value or 0 (zero).
The value specified by the parameter is a negative value.
The value specified by the parameter is a positive value or 0 (zero).
The value specified by the parameter is a negative value.
6. Parameters
Specify the setting or adjustment value by right justification (0 is not suppressed).
For example, when the setting value is "1", set it as "00001".
7. ID of the basic control command
This projector will respond to the computer only in the following cases.
- If the sent ID coincides with the projector ID.
- RESPONSE(ID ALL) in RS232C settings of this projector is ON and the sent ID is ALL.
- Or If Group (A-Z) of the sent ID coincides with GROUP in RS232C settings of this projector and
RESPONSE(ID GROUP) in RS232C settings of this projector is ON.
Specifically, please refer to a separate volume "Control Commands".
8. Response (Callback) of the basic control command
In the period when the command can be accepted.
Differs according to each command.
In the period when commands cannot be accepted.
In case of the parameter error or REMOTE2 effective.

9. Attention
・ If a command is transmitted after the lamp starts illuminating, there may be a delay in response or the command
may not be executed. Try sending or receiving any command after 60 seconds.
・ When transmitting multiple commands, be sure to wait until 0.5 seconds has elapsed after receiving the response
from the projector before sending the next command.
・ It might take time by the time the response returns because the command is processed in the projector.
Set the time-out to 10 seconds or longer.
・ When multiple projectors are all controlled
1) Set a different ID for each projector
2) Set [RESPONSE(ID ALL)] to [ON] in only one projector
3) Set [RESPONSE(ID ALL)] to [OFF] for all other projectors set in Step 2)
・ When multiple projectors are all controlled by group unit
1) Set a different ID for each projector
2) Set [RESPONSE(ID GROUP)] to [ON] in only one projector
3) Set [RESPONSE(ID GROUP)] to [OFF] for all other projectors set in Step 2)
4. 2. Control through LAN terminal
Connection and command transmission changes depending on mode (admin password is set or not with web control).
Control according to the procedure in "4.2.2" on the protection mode (the password is set), and according to the
procedure in "4.2.3" on the unprotected mode (the password is not set).
4. 2. 1. Connection example
4. 2. 2. When Web control administrator rights password is set (Protect mode)
4. 2. 2. 1. Connecting
4. 2. 2. 1. Connecting
1. Obtain the IP address and port number (Initial setting value = 1024) of the projector and request for a connection
to the projector.
You can obtain both the IP address and the port number from the menu screen of the projector.
・
: Obtain from the main menu → [NETWORK] → [NETWORK STATUS]
・
: Obtain from the main menu → [NETWORK] → [NETWORK CONTROL] → [COMMAND PORT]
2. Check the response from the projector
