External Control Manual
(for PX-42VR5/42XR3/50XR4/61XR3)
e.g., Personal computer
Application
These specifications are applicable to NEC plasma monitors and communications control from external equipment. "Please also support the command of VP series and refer to the manual of the conventional model about specification."
Connections
Connections should be made as described below.
1) Connector on the plasma monitor side: EXTERNAL CONTROL connector.
plasma monitor
Type of connector: D-Sub 9-pin male
No. Pin Name 1 No Connection
2 RXD (Receive data) 3 TXD (Transmit data) 4 DTR (DTE side ready) 5 GND
6 DSR (DCE side ready) 7 RTS (Ready to send) 8 CTS (Clear to send) 9 No Connection
External equipment

2) Connector on the external equipment side: Serial port (RS-232C) connector. See the specifications of the equipment that is to be connected for the type of connector and the pin assignment.
3) Wiring Use a crossed (reverse) cable. Wire the cable so that each pair of data lines cross between the two devices. These data line pairs are RXD (Receive data) and TXD (Transmit data), DTR (DTE side ready) and DSR (DCE side ready), and RTS (Ready to send) and CTS (Clear to send).
Communication Parameters

Communication Format
Command 1 Unit ID 1 Unit ID 2 Command 2 Data length Data Check sum
Command1
Command 1, along with command 2, is a number used to distinguish each command. When making it operate using ID, bit1 and bit0 are set up as follows.
Bit1,Bit0 Unit ID distinction bit
11B :Usually, a form (with no ID) 10B :Usually, a form (with no ID) 01B :Set ID 00B :Video wall ID
In the case of ACK, when the lower order 4 bits is FH (as in 3FH and 7FH), this indicates that the commands and data of the supported equipment have been received. When the lower order 4 bits is BH (as in 3BH and 7BH), this indicates that unsupported commands and data have been received.
Unit ID1,2 (UA1,UA2)
Unit ID 1 and unit ID 2 are numbers used to identify the equipment that is to be connected. 60H is used for the plasma monitor and 80H is used for external control equipment such as a personal computer.
4
1) Unit ID 1: Indicates the equipment sending the signal. When supporting Set ID by the command 1, 4 bits of low ranks of Set ID are set up.
2) Unit ID 2: Indicates the equipment receiving the signal. When supporting Set ID by the command 1, 4 bits of higher ranks of Set ID are set up.
* Set ID : it is the apparatus number assigned to each plasma monitor.
5
Total 208H
Command 2
Command 2, along with command 1, is a number used to distinguish each
command.
Check Sum (CKS), Error Processing, and ACK
1) The check sum described below and RS-232C odd parity are used together for a check of the received data. The check sum is the lower order 8 bits of one frame of sent or received data comprising the sum total of Command 1, Unit ID 1 and 2, Command 2, Data Length, and Data.
Check Sum Example
DFH 80H 60H 47H 01H 01H 08H
Command1 Unit ID1 Unit ID2 Command2 Data Length Data Check Sum
2) Error Processing
• When the communication interval is vacant for more than 4 ms, thereafter a
received Command 1 will be recognized. If, at this time, meaningful data cannot be recognized, that data will not be recognized (as valid data).
• An ACK will not be returned unless the receive data error, the check sum
error, and the receive data are all taken in.

The control method of the set by Set ID
When controlling two or more sets of plasma monitors, if the command using Set ID is used, it will become controllable individually. The example of the POWER ON command to the plasma monitor which set ID as "5" is shown below.
It is not based on ID but is the POWER ON command to all sets. 9F 80 60 4E 00 CD
In ID= "5", the value of ID-1=4 is set up. 9D 84 60 4E 00 CF
The example of a change in the single mode of a 4th page multi-system configuration and the multi-mode is shown below. ID of the set used as a master(etc PC) is set to 50, and it assumes that ID is shaken by AUTO ID to each set. ID shaken at each set is as follows.
Upper left set (master) ID = 50 = 32h Upper right set ID = 51 = 33h Lower right set ID = 52 = 34h Lower left set ID = 53 = 35h

Transmission of the above command performs a 4th page multi SPLIT display. Moreover, the following commands are published in order to change a 4th page multi-display into a single mode display.
DF 80 60 03 03 01 01 00 C7
All sets become a single mode display by the above-mentioned command. Since this command does not specify Set ID, all sets execute it.
*:Control by ID may not be able to be performed depending on connection with
external control apparatus.
