Hi everyone, I'm looking for the RS232 code to auto on/off our NEC
MultiSync P461. Wonder if anyone has this?
Thanks

Patricia,
You can find the NEC Multisync P461 manual here:
http://www.nec.com.au/media/docs/P461_User_Manual.pdf-cf079321-5c5b-43c9-9e70-8f59835475a9-0.pdf
External Code Codes Manual
http://www.necdisplay.com/cms/documents/UserManuals/External_Control.pdf
http://www.necdisplay.com/cms/documents/UserManuals/S_P_X_Series_ExternalControl.pdf
The RS232 Codes for Power on\off are:
7.2 Power control
1) The controller requests the monitor to control monitor power.
Header
SOH (01h): Start Of Header
'0' (30h): Reserved
Monitor ID: Specify the Monitor ID which you want to change a setting.
Ex.) If Monitor ID is '1', specify 'A'.
'0' (30h): Message sender is the controller.
'A' (41h): Message type is "Command".
'0'-'C (30h, 43h): Message length is 12 bytes.
Message
STX (02h): Start of Message
'C'-'2'-'0'-'3'-'D'-'6' (43h, 32h, 30h, 33h, 44h, 36h): power control command
'0'-'0'-'0'-'1' (30h, 30h, 30h, 31h): Power mode
0001: ON
0002, 0003: Do not set.
0004: OFF (same as the power off by IR)
ETX (03h): End of Message
Check code
BCC: Block Check Code
Refer to the section 4.5 “Check code” for a BCC calculation.
Delimiter
CR (0Dh): End of packet
Header Message Check code Delimiter
SOH-'0'-Monitor ID-'0'-'A'-'0'-'C' STX-'C'-'2'-'0'-'3'-'D'-'6'-
'0'-'0'-'0'-'1'-ETX BCC CR

Hi,
If someone could explain this to me, I'd greatly appreciate it. This is in regard to using hexidecimal codes to control an NEC MultiSync from a DMP using an RS232 connector.
When testing the codes to turn off the NEC screen, the follwing codes work:
020100000003
AND
3030220D
However, this code does not:
0130413041304302433230334436303030340D
What I don't understand is that the above two codes, which do work, are not documented in any NEC manuals, but rather, I found them while searching around on the internet and happen to find a manual on an Elmo expansion board (not at all related and odd beyond all belief, and even stranger, the second of the above two working codes is for a Mitsubishi projector, not even a flatscreen).
The latter, not working, code is painstakingly based on the NEC manual, as follows:
01 Start
30 0 - reserved
41 A - The first monitor in the array
30 0 - Message sender is the controller
41 A - Message type is command
30 0
43 C - This and above one is the message length
02 STX Start the message
43
32
30
33
44
36 - This and above set are the power control command
30
30
30 - Describes the power mode
34 - To turn the power off
33 - To do nothing
32 - To do nothing
31 - To turn the power on
0D - end
So, where did the working code come from? And why won't the approved and blessed NEC codes work? I also tried variations from other posts in this thread and they didn't work either. I'm at a total loss, and I may have slipped unknowingly into an alternate universe, if someone doesn't slap me and get me back out of it.
Thanks!

Hi Tomas
I am having some problems determining the correct codes for an NEC multisync LCD4020 pannel
I have the information from the NEC manual but not sure how this translates to the DMP HEX codes
1) The controller requests the monitor to control monitor power.
Header
SOH (01h): Start Of Header
'0' (30h): Reserved
Monitor ID: Specify the Monitor ID which you want to change a setting.
Ex.) If Monitor ID is '1', specify 'A'.
'0' (30h): Message sender is the controller.
'A' (41h): Message type is "Command".
'0'-'C (30h, 43h): Message length is 12 bytes.
Message
STX (02h): Start of Message
'C'-'2'-'0'-'3'-'D'-'6' (43h, 32h, 30h, 33h, 44h, 36h): power control command
'0'-'0'-'0'-'1' (30h, 30h, 30h, 31h): Power mode
0001: ON
0002, 0003: Do not set.
0004: OFF (same as the power off by IR)
ETX (03h): End of Message
Check code
BCC: Block Check Code
Refer to the section 4.5 “Check code” for a BCC calculation.
Delimiter
CR (0Dh): End of packet
Do you have some pointers here?
Cheers

Using following codes:
3. Create system task "TV ON"
use type "set"
rs232.tx_hex=3030210D
4. Create system task "TV OFF"
use type "set"
rs232.tx_hex=3030220D
5. RS232 Fetch Settings (This setting will allow you to check the RS232 settings)
Get
p=rs232.*

Tomas,
would you be able to provide me the codes to power on and off an NEC 462 digital display.
Thanks in advance.

For those who are having trouble finding HEX codes for NEC screens, NEC has a tool called PD Comms Tool that sends control commands via rs232 or LAN and returns the relevant hexadecimal value, which can be added to a command query string in the DMM.
Here is the tool:
