Has anyone cracked the code on an URC MX-5000 for a JVC projector using IP?  I can get a PJ_OK test response but can't get a command to work.  I am not sure where/how to put the PJREQ for a handshake.  I have the Denon working, DirecTV working IP, still need to get the Sony BD, projector and iTach for screen going.  But for now, if I could get the code cracked on 1 command for the projector, I am sure I can do the rest myself.  Power on is:

21 89 01 50 57 30 0A
but to communicate you need to initiate connection, receive a PJ_OK (which I do receive so IP and port is correct) and respond in 5 seconds with PJREQ.  Somehow that is where I just can't get it coded right.
The projector is a 2012 D-ILA RS45U

actually you can get a quite precise manual of IP/RS-232 control of those projectors from JVC web site. This is good news. Bad news are that it won't help you, I suggest. The reason why - they done IP control protocol weird. I tried to implement it in one of my crestron projects, but after couple of hours decided to use RS-232, and let me tell you why. IP control looks like two parts - first off all you should establish a connection to the socket:

Crestron: Hi, who's there?
JVC: I'm JVC Projector
Crestron: Let me send you a command?
JVC: Well. Do it.

After that control system should send a command within 5 seconds, because if there was no activity - projector closes a socket and you should start over.

So it means that if you need to send ANY command - you should start with initializing procedure, even if you just asking status response. And there is no way to eliminate this (as far as I know).

Good luck

Thanks Yecora, I have tried it umpteen ways but just can't get the timing right to connect, send PJREQ handshake, receive J_ACK and send power on Hex or ASCii command.  May need pauses after connection?  Tried it but that did not work yet.  I am using a URC MX-5000.  I suspect until someone writes a true 2-way module those type remotes will have trouble.  I can do it on Roomie Remote, not sure how they wrote it and even then doubt the iOS language would translate.  I can also do it with Hercules (from one of the manuals you reference a free virtual termina emulator) by establishing connection, quickly sending PJREQ, then quickly sending power on hex, oila, projector is on.  SO, it works but I have no idea how to write it in CCP.  I mean, JVC, are there REALLY that many people hacking in and turning projectors on, through a firewall?  I suspect they would get my or clients quicken way before changing my screen size!

Using Wireshark (free utility to watch traffic on LAN), I get this using Hercules set-up Utility (a Virtual Terminal), it works to turn on projector (the second line is the ...PW Power on acknowledgement):


PJ_OK..,2.....,20..PJREQPJACK!..PW1
...PW

I get this using URC:
PJ_OK..,2.....,20..PJREQ,,,,21 89 01 50 57 31 0A

I am sending this in Hercules:

1. Click Connection command button on test mode window, correct IP and port 20554
2. I receive in virtual terminal: PJ_OK
3. I then immediately send in ascii: PJ_REQ
4. I receive: PJACK
5. I then Immediately send in HEX: 21 89 01 50 57 31 0A

My URC MX-5000 Macro in CCP looks like this:
..,2.....,20..PJREQ,,,,21\x2089\x2001\x2050\x2057\x2031\x200A

• Port and IP correct
• I receive PJ_OK upon sending command
• ASCII selected, automatic carriage return selected

Any ideas?  Seems I am almost there but not getting the acknowledgement ‘PJACK’ so my power on is not accepted.

this does not work either as a macro in URC:

..,2.....,20..PJREQ!..PW1

Wireshark result (still no PJACK and no poweron:

PJ_OK..,2.....,20..PJREQ!..PW1

well, just in case

is that LAN watch utility can get info about Samsung TV IP control protocol?

Yecora, I think it would work if you can send the commands from a PC with the software on it and you know the IP address and port.  Create a filter to weed out all unneccessary traffic.  The filter is typed like this where the variables are those for your TV:

tcp port 20554 and host 10.0.1.22 

VERY VERY CLOSE NOW to controlling JVC Projector with URC MX-5000!  I have the URC terminal emulator in CCP working from URC MX-5000 to JVC, but when untethered the remote does not work, it does control other IP devices and is internet connected.   I am thinking delay issue of remote vs PC?
Macro as follows  ( entered them as hex and URC can show convert in ASCII screen as here):

Delay .5 second
PJREQ
Delay 1.0 seconds
!\x89\x01PW1\x0A
Delay .5 seconds
