Projector Control Command Reference Manual ©NEC Display Solutions, Ltd. 2014-2017 BDT140013 Revision 6.1 Introduction This manual describes the commands used to control an NEC-made projector from a PC or other external device. A projector can be controlled by exchanging commands with an external device connected via a serial port or network. The manual assumes basic knowledge of projectors. For information about the functions of the model in use and how to adjust the device, see the operation manual of the projector .For information about the connection between the projector and an external device, see "1 Connecting an External Device" (page 5). Connect an external device as appropriate for the usage environment of the projector. Models for which the control commands are available See the Appendix "Connecting an External Device". Conventions For information about how commands and responses are expressed in this manual, see "2.1 Understanding command details" (page 10). NOTES 1. The acts of disclosure, duplication, and modification of part or whole contents in this reference manual without permission are prohibited. 2.

Parameter A character string in italic enclosed in brackets represents a parameter. For information about the parameters that are common to the control commands (ID1, ID2, CKS, LEN, ERR1, and ERR2), see "2.2 Parameters" (page 10). For information about those parameters whose content varies from command to command (DATA), see the description of the relevant command. 2.2 Parameters The parameters that are used in the control commands are listed below. Parameter name Description ID1 Control ID The value of the "control ID" set for the projector is used. ID2 Model code This varies depending on the model in use. CKS Checksum The checksum is calculated as follows. ① Add all preceding bytes of data. ② Use the value of the low-order one byte (eight bits) of the addition result obtained in ① as the checksum. LEN Data length This indicates the data length of the data part (DATA??) following LEN (in bytes). DATA?? Variable length data This varies depending on the character string stored. ERR1 Response error The cause of an error is represented by a combination of error codes. ERR2 For information about error codes, see "2.4 Error code list" (page 12). Example of checksum calculation 20h 81h 01h 60h 01h 00h ① Add all the data preceding the checksum. "20h + 81h + 01h + 60h + 01h + 00h = 103h" ② Use the low-order one byte "03h" of the addition result obtained in ① as the checksum. ©NEC Display Solutions, Ltd. 2014-2017 10 2.3 Responses After a command is sent to the projector, its result is returned as a response. How a response is returned differs depending on the execution result of the command. When the execution of a command succeeds When the command does not request data, a response is returned with no data part. When the command requests data, a response is returned with data added to data parts. When the execution of a command fails A response is returned with the cause of the failed command execution indicated in and .
