I. Application

This document defines the communications method for control of the NEC LCD monitor, MultiSync E705

/E805 when using an external controller.

(3/104)

II. Preparation

2. Connectors and wiring

2.1 RS-232C Remote control

Connect or: 9-pin D-Su b Cable: Cross (reverse d) cable or null modem cable

(Please refer “Controlling the LCD monitor via RS-232C Remote control” on User’s manual.)

2.2 LAN control

Connect or: RJ-45 10/1 00 BASE-T Cable: Category 5 or higher LAN cable

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

(4/104)

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 AS CII

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 moni tor again, after 15 mi nutes or more.

3.3 Communication timing

The controller should wait for a reply packet before the next command is sent. (Note) When the followi ng commands are sent, a controller shou ld wait for specifi ed 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

STX



Command code '0' '7'

Send "07"(30h, 37h) as Get Timing Report command. Complete "Get Timing Report" command packet as follows;

SOH-'0'-'A'-'0'-'A'-'0'-'4'-STX-'0'-'7'-ETX-CHK- CR

Command SS H Freq. V Freq. ETX

5.5.3 NULL Message

STX

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



01h-30h-30h-41h-42h-30h-34h-02h-42h-45h-03h-CHK-0Dh

SOH-'0'-'0'-'A'-'B'-'0'-'4'-STX-'B'-'E'-ETX-CHK- CR

Command code 'B' 'E'

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

A 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.

A null message will be returned by the monitor if the “Stop Proof of Play” command is sent and the mo nitor has not started Proof of Play.

Complete " NULL Message" command packet as follows;

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.

Step 1. The controller requests the Monitor to reply with the current brightness setting and capability
