Blue is from JVC Projector, Red is from URC MX-5000:

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.
