1. Projector Control
----------------------------------------------------------------------
NEC projectors make use of control commands that control the functions of the projector via connection with
a personal computer or another device.
======================================================================
2. Connection Method
----------------------------------------------------------------------
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.

* 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.

5. Command Descriptions
----------------------------------------------------------------------
Precautions with Inscriptions:
(*1) Projector ID
It is the value when forwarding a factory.
This reflects the "Projector ID" that has been set to the projector.
(*2) Model code: "xxH" inscription
This will differ depending on the projector.
In case of MT/NP1000/1050 series 10H
In case of LT/LT80 series 20H
In case of VT series 40H
In case of GT series 50H
In case of HT series 60H
In case of WT series 70H
In case of HT10 series D0H
In case of LT180 series D0H
In case of LT30 series D0H
In case of NP40 series D0H
In case of NP4000 series 80H
(*3) Checksum: "CKS" inscription
This is the value of the lower 8 bits of the results calculated in byte units from all of the data up to the
immediately preceding data.
Example:
20H 81H 01H 60H 01H 00H 03H
+ + + + + + = CKS
(*4) Response error number
This is the value of the error number at the time of an error.
See "NAK" of "6-2. Data portion of response".
(*5) Term “RGB” and “COMPUTER”
On the HT1100, VT770, LT245/ LT265/ LT280/ LT380,
NP1000/NP2000/NP1150/NP2150/NP3150/NP4000/NP4001, LT25/ LT30/ LT35, VT48/ VT480/ VT580,
VT49/VT490/VT590/VT595/VT695/VT700 and NP40/NP50/NP60, the term "RGB connector" has been
changed to "COMPUTER".
(*6) Term “DVI” and “COMPUTER”
On the LT380, NP1000/NP2000/NP1150/NP2150/NP3150/NP4000/NP4001 and VT595/VT695/VT700, the
term "DVI connector" has been changed to "COMPUTER".
