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).

2.1 Understanding command details
In this manual, commands and responses are expressed as follows.
20h 88h <ID1> <ID2> 0Ch <DATA01> - <DATA12> <CKS>
Command/response A series of strings enclosed in a frame represents a command or response (in
hexadecimal notation).
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.
①Add all preceding bytes of data.
②Use the value of the low-order one byte (eight bits) of the addition
result obtained in ①as 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
ERR2
Response error The cause of an error is represented by a combination of error codes.
For information about error codes, see "2.4 Error code list" (page 12).
Example of checksum calculation
20h81h01h60h01h00h<CKS>
①Add all the data preceding the checksum.
"20h + 81h + 01h + 60h + 01h + 00h = 103h"
②Use the low-order one byte "03h" of the addition result obtained in ①as the checksum.
