External Control NEC LCD Monitor

1. Application

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

LCD4020/4620/5220/6520 and MULTEOS M40/46 when using an external controller .

2. Connectors and wiring

Connector: D-Sub 9-pin

Cable: Cross (reversed) cable or null modem cable

(Please refer “Using the LCD with RS-232C” on each User’s manual.)

3. Communication Parameter

(1) Communication system Asynchronous

(2) Interface RS-232C

(3) Baud rate

(4) Data length

(5) Parity

9600bps

8bits

None

(6) Stop bit 1 bit

(7) Communication code ASCII

3.1 Communication timing

The controller should wait for a packet interval before next command is sent.

The packet interval needs to be longer than 600msec for the LCD monitor.

(1/40)

4. Communication Format

Header Message Check Code Delimiter

The command packet consists of four parts, Header, Message, Check code and Delimiter.

Sequence of a typical procedure to control a monitor is as follows,

13. Security Lock

13.1 Security Lock Control

This command sets the condition of security lock function to "LOCK" or "UNLOCK".

If security pass codes 1st to 4th are matched with monitor resisted pass codes, then this command is executed, and reply no error status and a new condition.

If codes aren't matched with them then setting isn't changed, and reply error status and a current condition.

If the monitor receives this command while waiting for Pass codes inputs, then it only checks Pass cords (and releases image muting if Pass codes are OK) and doesn't apply "EN" parameter.

1) The controller requests the monitor to set the condition of security lock.
