5.3 Command Control via the Network

You can configure and control the projector via the network using RS-232C commands.

Communication Port

The following two ports are assigned for the command control.

TCP #23

(Network Control Port1 (Port: 23))

TCP #9715

(Network Control Port2 (Port: 9715))

NOTE

• Command control is available only via the specified port above.

Command Control Settings (&21)

Configure the following items from a web browser when command control is used.

Example: If the IP address of the projector is set to 192.168.1.10:

1) Enter “ http://192.168.1.10/” into the address bar of the web browser, and select

Projector Web Control from the selection window.

2) Enter your user name and password, and then click the [OK].

3) Click the [Port Settings] on the main menu.

4) Click the

[Enable] check box to open Network Control Port1 (Port: 23) to use

TCP #23. Click the [Enable] check box for the [Authentication] setting when authentication is required, otherwise clear the check box.

5) Click the [Enable] check box to open Network Control Port2 (Port: 9715) to use TCP #9715. Click the

[Enable] check box for the [Authentication] setting when authentication is required, otherwise clear the check box.

6) Click the [Apply] button to save the settings.

5.3 Command Control via the Network (continued)

When the authentication setting is enabled, the following settings are required.

(&32)

7) Click the [Security Settings] on the main menu.

8) Click the [Network Control] and enter the desired authentication password.

* See NOTE.

9) Click the

[Apply] button to save the settings.

NOTE

• The Authentication Password will be the same for

Network Control

Port1 (Port: 23), Network Control Port2 (Port: 9715) and PJLink™ Port

(Port: 4352).

• The new configuration settings are activated after restarting the network connection. When the configuration settings are changed, you must restart the network connection. You can restart the network connection from Network

Restart on the main menu. (&38)

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. (&RS-232C Communication in the Operating Guide - Technical)

However, the following reply will be sent back in the event of authentication failure when authentication is enabled.

<Reply in the event of an authentication error>

Reply

0x1F

Error code

0x04 0x00

● TCP #9715

Send Data format

The following formatting is added to the header (0 x 02), Data length (0 x 0D),

Checksum (1 byte) and Connection ID (1 byte) of the RS-232C commands.

Connection ID

→ This is the value to make zero on the addition of the lower 8 bits from the header to the checksum.

→ Random value from 0 to 255 (This value is attached to the reply data)

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 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) Connect the projector.

2) Receive the random 8 bytes “a572f60c” from the projector.

3) Bind the random 8 bytes “a572f60c” and the Authentication Password

“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.
