Table 5-9. List of error parameters Parameters 0x0001 Error type Network in use 0x0002 No applicable setting 0x0003 0x0004 0x0005 0x0006 0x0007 0x0008 0x0009 0x000A Resource error Download in progress Setting not currently possible Lamp off Error between projector and EasyMP.net EasyMP.net rebooting Status mismatch Projector error 0x000B Network not connected 0x000C 0x000D Locked Not available for stack Error condition An attempt was made to communicate with the projector via a network connection, but another computer was already communicating with the projector. Parameter is outside the setting range and FromTo is incorrect. Command is not supported, or unknown command. Insufficient EasyMP.net resources. Projector is in download mode. The apply command received cannot be processed. Projector lamp is switched off. When the command was sent via EasyMP.net and too many retries or timeouts occur between EasyMP.net and the projector, it indicates an error upstream from EasyMP.net. EasyMP.net is at end sequence. A command which was different from the expected command was received. When too many retries or timeouts occur between master and slave projectors when connected in a stack, it indicates an error upstream from the master projector. An attempt at communication with the computer (network) was made, but no computer (network) exists. An item which has been locked by the administrator (installer) was specified. A command which cannot be used for a stack configuration was specified. (8) Checksum : Represent checksum (1 byte) Checksum calculation method All bytes of data from the size to the parameters is added together, and the twos complement of the result in hexadecimal format is subtracted from 0x0100 to obtain the checksum. Example) For the command "1D 0007 01 10 00 02 0A CS" 0x00 + 0x07 + 0x01 + 0x10 + 0x00 + 0x02 + 0x0A = 0x24 ---> 0x0100 - 0x24 = 0xDC 8 of 20
