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

 

V321,V461 

and LCD4215

(R)

 

when using an external controller

.

 

 

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

 ( Except LCD4215

(R)

)

 

 

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.) 

 

3. Communication Parameter
