Page 4: Application
I. Application This document defines the communications method for control of the NEC LCD monitor, MultiSync P403/ P463 /P553 when using an external controller. (4/137)
Page 5: Preparation
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...
Page 6 (Please refer “Controlling the LCD monitor via LAN control” on User’s manual.) (6/137)
Page 7: Communication Specification
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 packet interval before next command is sent. The packet interval needs to be longer than 600msec for the LCD monitor. (7/137)
Page 8: Communication Format
4. Communication Format Header Message Check Code Delimiter The command packet consists of four parts, Header, Message, Check code and Delimiter. Recommended sequence of a typical procedure to control a monitor is as follows, [A controller and a monitor, two-way communication composition figure] ■...
