I. Application

This document defines the communications method for control of the NEC LCD monitor, MultiSync P403/ P463 /P553 /P703 /P801 /X464UN /X554UN /X464UNV /X554UNS when using an external controller.

(4/141)

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.)

2.2 LAN control

Connector: RJ-45 10/100 BASE-T Cable: Category 5 or higher LAN cable

(5/141)

(Please refer “Controlling the LCD monitor via LAN control” on User’s manual.)

(6/141)

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)
(4)	IP address	* Using the payload of TCP segment.
		(Default) Automatic setup
		* If you need to change,
(5)	Port No.	Please refer “Network settings” on User’s manual.
		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 next command is sent. (Note)

A normal answer cannot be performed when a monitor is a busy state. Please refer “5.5.3 NULL message”.

Specify a commands receiver’s address.

The controller sets the “MONITOR ID” or “GROUP ID” of the monitor controlled in here.

On the reply, the monitor sets ‘0’ (30h), always.

(9/141)

Ex.) If you want to control a monitor that has the "ID No." as '1', specify a destination address 'A'(41h). If you want to control all of the monitors which are connected by a daisy chain, specify a destination address ‘*’(2Ah).

The controller must be ‘0’ (30h).

On the reply, the monitor sets the own MONITOR ID in here.

5thbyte) Message Type: (Case sensitive.)

Refer to section 4.2 “Message block format” for more details.

ASCII 'A' (41h): Command.

ASCII 'B' (42h): Command reply.

ASCII 'C' (43h): Get current parameter from a monitor.

ASCII 'D' (44h): "Get parameter" reply.

ASCII 'E' (45h): Set parameter.

ASCII 'F' (46h): "Set parameter" reply.

6th -7th bytes) Message Length:

Specify the length of the message (that follows the header) from STX to ETX. This length includes STX and ETX.

The byte data must be encoded to ASCII characters.

Ex.) The byte data 3Ah must be encoded to ASCII characters '3' and 'A' (33h and 41h). The byte data 0Bh must be encoded to ASCII characters '0' and 'B' (30h and 42h).

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,
	STX	OP code			OP code			ETX
			page
		Hi		Lo	Hi		Lo

ØRefer to section 5.1 “Get current parameter from a monitor.” for more details.

2)Get Parameter reply

The NULL message returned from the monitor is used in the following cases;

ØTo tell the controller that the monitor does not have any answer to give to the host (not ready or not expected)

ØFollowing operation s need 15 seconds for to execute, so the monitor will return this message when another message is received during execution.

²Power ON and Power OFF

ØFollowing operations need 10 seconds for to execute, so the monitor will return this message when another message is received during execution.

²Auto Setup, Input, PIP Input, Auto Setup and Factory reset.

ØA null message will be returned by the monitor if the “Start Proof of Play” command is sent and the monitor has already started Proof of Play.

ØA 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.
