NAK return

In the following cases, the projector returns the command with “:N” added.

(1)Though the command sent from the computer is received by the projector successfully, it cannot be executed because the projector is in the operation prohibition state.

(2)The data length of the sent command is incorrect or the command is invalid.

When a command is sent out during the following operations, it may not be executed.

(1)During signal switching

(2)In the process of the auto position

(3)After the power is turned on.

The projector receives no commands for about 20 seconds (or for 2 minutes at the longest if the lamp does not light up promptly as the life is expiring). In this case, the projector returns the received command with NAK added.

The return command is sent out within 1 second at the latest.

When sending commands successively, wait to receive the return command of the current command before sending a next command.

The projector may not receive a command when the splash screen is being displayed immediately after turning on the power. Use command “00r10” to cancel the splash screen.

While using the LAN terminals, the LAN functions take precedence.

For the LAN terminals, the same commands as those for connecting with the TCP/IP (port number 63007) are avail- able. Note, however, that the response becomes slightly slower than when using the RS-232C terminals.
