Control for NP-PA803UL / new protocol?

Tray Schaeffer All Messages By This Member #245664 All,? Working with new laser projectors here at a job site.? Set the PC cotnrol within the projector to 38400.? Unfortunately, control via HDBaseT is not available due to the way things are wired.? These are connected to DM-RMC-200 receivers from DM 32x32 (not CPU3).? DM endpoints reports on line but have no comms at all with projector. Stereo mini is connected to the PC Control input on display, not the IR remote input next to it.? Anyway, Seems that the control protocol may have changed since I last worked with one of these.? See this document.? ? https://assets.sharpnecdisplays.us/documents/miscellaneous/pj-control-command-appendixes.pdf ? The NP-PA803UL is listed.? Not sure if the command should include the preceding number or not..? From the document, power on = "015. POWER ON". Not sure of terminating char, if any is required.? ? Any experience with these?? Thanks in advance,? Tray
Andy Ross All Messages By This Member #245665 I believe with those you have to go into the settings and manually select which port ( HDBaseT or RS-232 ) is being used for control. Is there network to it? I believe it is Crestron/RoomView connected so you can control it over the network.

Power On is the actual command just the command number and name (if you look at other fields in the document there are hex bytes provided for e.g. DATA 02 and DATA 03. I think you’re missing the actual protocol document. ? See page 190 of for (a portion of) the protocol where power on = \x02\x00\x00\x00\x00\x02. ? I’ve been able to throw more or less the same commands at every NEC projector I’ve seen in the past 12ish years. Incidentally there was a run of NEC projectors that would randomly lock up the COM ports at 38400 (or maybe at 38400 + DM); setting the baud to 9600 resolved that issue so more or less out of superstition I’ll always set a NEC projector to 9600 rather than leaving it at 38400 . ? -- Lincoln King-Cliby, CTS, DMC-E-4K/T/D Commercial Market Director Sr. Systems Architect \| Crestron Certified Master Programmer (Diamond) ControlWorks Consulting, LLC Direct: (+1)440.771.4807 \| Cleveland: (+1)440.449.1100? \| Boston: (+1)508.695.0188 \| DC: (+1)202.381.9070? \| Fax: (+1)440.449.1106 Crestron Services Provider \| Biamp Authorized Independent Programmers \| Extron Qualified Independent Programmer ? toggle quoted message Show quoted text From: [email protected] [mailto:[email protected]] On Behalf Of Tray Schaeffer Sent: Friday, April 08, 2022 8:48 AM To: [email protected] Subject: [crestron] Control for NP-PA803UL / new protocol? ?
