I. Application
This document defines the communications method for control of the NEC LCD monitor, MultiSync P404 /P484 /P554 /V404 /V484 /V554/ V404-T/ V484-T/ V554-T/ P754Q/ V754Q/ V864Q/ V984Q/ C751Q/ C861Q/ C981Q when using an external controller.
II. Preparation
2. Connectors and wiring
2.1 RS-232C Remote control
Connector: 9-pin D-Sub
Cable: Cross (reversed) cable or null modem cable
(Please refer “Controlling the LCD monitor via RS-232C Remote control” on User’s manual.)
(4/139)
2.2 LAN control
Connector: RJ-45 10/100 BASE-T
Cable: Category 5 or higher LAN cable
(Please refer “Controlling the LCD monitor via LAN control” on User’s manual.)
(5/139)
III. Communication specification
3. Communication Parameter
3.1 RS-232C Remote control
(1) Communication system Asynchronous (2) Interface RS-232C (3) Baud rate 9600bps (4) Data length 8bits (5) Parity None (6) Stop bit 1 bit (7) Communication code ASCII
3.2 LAN control
(1) Communication system TCP/IP (Internet protocol suite) (2) Interface Ethernet (CSMA/CD) (3) Communication layer Transport layer (TCP) * Using the payload of TCP segment. (4) IP address (Default) Automatic setup * If you need to change, Please refer “Network settings” on User’s manual. (5) Port No. 7142 (Fixed)
(Note) The monitor will disconnect the connection if no packet data is received for 15 minutes. And the controller (PC) has to re-connect to control the monitor again, after 15 minutes or
more.
3.3 Communication timing
The controller should wait for a reply packet before the next command is sent. (Note) When the following commands are sent, a controller should wait for specified period after receiving the reply command before sending the next command.
Power On, Power Off: 15 seconds
Input, PIP Input, Auto Setup, Factory Reset: 10 seconds

4. Communication Format
Header Message Check Code Delimiter
The command packet consists of four parts, Header, Message, Check code and Delimiter.
Note: Don't add extra data (Example: padding data) after Delimiter.
Recommended sequence of a typical procedure to control a monitor is as follows,

4.2 Message block format
“Message block format” is allied to the “Message Type” in the “Header”.
Refer to the section 4.1 “Header block format” for more detail.
1)Get current parameter
The controller sends this message when you want to get the status of the monitor.
For the status that you want to get, specify the “OP code page” and “OP code”,
refer to “Appendix A. Operation code table”.
“Message format” of the “Get current parameter” is as follows,
Refer to section 5.1 “Get current parameter from a monitor.” for more details.

To tell the controller that the monitor does not have any answer to give to the host (not
read y o r n ot e x p e c t e d)
A n u l l m e s s age will be returned by the monitor if the “Start Proof of Play” command is
sent and the monitor has already started Proof of Play.
A null message will be returned by the monitor if the “Stop Proof of Play” command is sent
and the monitor has not started Proof of Play.

6. Typical procedure example
The following is a sample of procedures to control the monitor, these are examples of "Get
parameter", "Set parameter" and "Save current settings".
6.1. How to change the “Backlight” setting.
