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)

(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
