Control Commands for NEC Projector (Basic) Rev 08.04.14a
Copyright (C) NEC Display Solutions, Ltd. 2002-2014
--------------------------------------------------------------------- Updated on August 4, 2014
--------------------------------------------------------------------- This file contains information about NEC projector control commands.
---------------------------------------------------------------------The following 3 kinds of connection methods are available for sending and receiving control commands.
1. Serial connection using the serial port on the projector
A serial cable is required.
2. USB connection using the USB port on the projector
A USB cable is required.
3. LAN connection
3-1. LAN connection using a wired LAN card
A wired LAN card and LAN cable are required.
3-2. LAN connection using a wireless LAN card
A wireless LAN card is required.
3-3.LAN connection using the LAN port on the projector
A LAN cable is required.
3-4. LAN connection using a wireless LAN unit
A wireless LAN unit is required
Status of supported connection
* A USB cable is supplied as standard with the MT860/1060/1065/1075.
* The GT5000/6000 does not come with a USB cable.
* Note that a connection method using the supplied USB cable is not supported for the LT220/240/260.
* The serial cable, LAN card and LAN cable are separately sold.
* The WT610 replaced the WT610 and uses the same command set.
(CAUTION)
Before making connections, be sure to invalidate the standby mode of the projector and set the "idle mode". The
projector cannot use the control commands in the standby mode.
Setting method: Under projector [Projector Options] --> [Setup], enter a check for [Idle Mode] on Page 4.
( CAUTION ) (!1)
Before making connections, be sure to select [NORMAL] for [STANDBY MODE].
Setting method : From the projector's menu, select [SETUP] --> [OPTIONS(2)] -->[STANDBY MODE]--> [NORMAL].
( CAUTION ) (!2)
The projector accept the "POWER ON" command during [POWER-SAVING] mode for[STANDBY MODE].
Supplement:
(!1) Only the NP600/NP610/NP3200 series is compatible.
(!2) Only the M300 series is compatible.
---------------------------------------------------------------------The communications method conforms to the RS-232C standard.
* A USB cable is supplied as standard with the MT860/1060/1065/1075.
* The GT5000/6000 does not come with a USB cable.
* Note that a connection method using the supplied USB cable is not supported for the LT220/240/260.
* The serial cable, LAN card and LAN cable are separately sold.
( CAUTION )
Before making connections, set the standby mode of the projector to "NORMAL" or "Idol mode".
The projector cannot use the control commands in the power-saving condition, but the following model can use
some control commands.
Baud rate: 38400 bps
(NP600 series, NP610 Series, VT60/VT70/VT80/VT90 series, VT700: 19200bps)
Data length: 8 bits
Parity bit: No parity
Stop bits: 1 bit
Communications mode: Full duplex
The control connector is described below.
[ HT/LT/NP40/VT70/VT80/VT90/WT ]
The PC CONTROL connector is a mini DIN 8-pin connector.
1 To TxD of PC
2
3
4 To GND of PC
5
6
7 To RxD of PC
8
* 2, 3, 5, 6, and 8 are used inside the projector.
---------------------------------------------------------------------On the LT/MT/SX/GT series projectors communication is done in a frame
composed of header, data, and checksum.
The frame sent from the controller to the projector is referred to as
a command, and the one sent from the projector to the command as an
reply is referred to as a response.
The response has two types; Acknowledge (hereafter referred to as ACK)
that recognizes a command and Negative Acknowledge (hereafter referred
to as NAK) that fails to recognize a command.
4-1. Frame Format
**********************************************************************
One frame comprises a header, a data portion, and a checksum.
Frame Format:
+-------------------------------+----------------------+--------+
| Header portion | Data portion |Checksum|
| | (Max. 4095 Bytes) | |
+-----+-----+-----+-------+-----+-----+-- --+-------+--------+

| | | | +------------- Data length
| | | +-------------------- Model code
| | +------------------------- Projector ID
| +------------------------------- ID2
+------------------------------------- ID1
* ID1: (8 Bit)
This is an identification data assigned to each command.
Command :
This sets an identification data assigned to each command to send it.
( See each command description.)
Response :
This returns the 6th bit of received ID1 as HIGH.
For ACK it sends the 8th bit back as LOW (recognized); for NAK it
sends the 8th bit back as HIGH (not recognized).
* ID2: (8 Bit)
This is an identification data assigned to each command.
Command :
This sets an identification data assigned to each command to send it.
( See each command description.)
Response :
This returns the value of received ID2 as is.
* Projector ID : (8 Bit)
This is a projector ID for the projector that sends and receives
frames.
Command :
This specifies a projector ID for the projector that sends and
receives commands. (individual notification)
Entering 00H or FFH becomes a common command for all the projectors.
(broadcast notification)
This is convenient for controlling multiple projectors at the same
time.
* When the controller is connected with the projector on a one-to-one
basis Broadcast notification is recommended.
* When the controller is connected with multiple projectors
To control a certain projector, use "individual notification".
For all others "broadcast notification" is recommended.
Response :
This returns the projector ID for a projector received regardless of
individual notification or broadcast notification.
CAUTION :
To notify individually, specifying a model code from the following
model codes is required.
* Model code: (4 Bit)
This is a model code for the projector that sends and receives frames.
Command :
This specifies a model code for the projector that sends commands.
(individual notification)
Entering 0000B or 1111B becomes a common command for all the
projectors. (broadcast notification)
This is convenient for controlling multiple projectors at the same
time.
* When the controller is connected with the projector on a one-to-one
basis Broadcast notification is recommended.
* When the controller is connected with multiple projectors
To control a certain projector, use "individual notification".
For all others "broadcast notification" is recommended.
Response :
This returns the model code for a projector received regardless of
individual notification or broadcast notification.
Table of Model codes
------------------------------------------ 0000B : (broadcast notification)
0001B : MT Series
0010B : LT Series
0011B : SX Series
0101B : GT Series
1111B : (broadcast notification)
CAUTION :
* When the model code is set to "broadcast notification", the command
becomes broadcast notification command, regardless of values of the
projector ID.
* Model code is specified using upper ranking 4 bits of data length.
The lower ranking 4 bits becomes the upper bits of data length.
* Data length : (12 Bit)
This is data length of data portion (unit:: byte).
Command :
This sets data length of data added to a command to send it.
( See each command description.)
Response :
This sets data length of data added to a response to send it.
( See each command description.)
CAUTION :
Data length is specified using total of 12 bits ( 0 - 4095) of 4 bits
of the 4th byte and 8 bits of the 5th byte.* The upper ranking 4 bits
of the 4th byte is model code.
* Data portion
This becomes data of data length specified in the data length portion.
Command :
This sets data added to a command to send it.
( See each command description.)
Response :
This sets data added to a response to send it.
( See each command description.)
* Checksum
This is lower ranking 8 bits of the sum total of the header and data
portions of one transmit and receive data frame.
4-2. Data portion of response
**********************************************************************
For ACK
This returns ACK without adding data portion to the command that does
not request data.
This returns ACK with adding data to the data portion for the command
that requests data.
For NAK
This adds a cause of not accepting the command to data portion to
return it.
