luminenterprises@gmail.com Posted March 22, 2019 Share Posted March 22, 2019 Need assistance developing an Optoma EH336 projector serial driver. Attached are RS232 codes I received from Optoma. Willing to pay someone for this driver but need it done fast. Please let me know if you are interested. Thanks. RS232.pdf Quote Link to comment Share on other sites More sharing options...
jackstone Posted April 4, 2019 Share Posted April 4, 2019 Why not just build a one-way serial driver using the Driver Wizard? This will take 2min max... Quote Link to comment Share on other sites More sharing options...
luminenterprises@gmail.com Posted April 4, 2019 Author Share Posted April 4, 2019 I built a IR driver for it but I need discrete input codes that only RS232 offers. I’m not familiar with RS232 code and have tried but have not been sucssesful building one in the driver wizard. Maybe some examples of how to write the codes or screen shots would help?

jackstone Posted April 4, 2019 Share Posted April 4, 2019 There is some special control characters to know about but it's not hard to figure out... I would have done it for your but this cannot be done blind, I need an actual unit to test and I did not. I may have one in a week or two.

luminenterprises@gmail.com Posted April 4, 2019 Author Share Posted April 4, 2019 I’ll pay you a per hour charge to teach me the code on a screen share so I can test locally. Call me to discuss. 480-415-6352. Quote Link to comment Share on other sites More sharing options...
jackstone Posted April 5, 2019 Share Posted April 5, 2019 This is feasible but would require an odd setup that would allow me to see the projector status trough a teamviewer session (maybe and USB webcam or something), by seeing it that would be easy to create a very basic unidirectional driver using the Driver Wizard. I may not call you, I'm not a phone guy, but if you can setup something to allow me to see the projector, we can certainly schedule moment to work on that and that should be quick. You need to make sure the RS-232 wiring is good, properly connected to the controller, and find some way to plug the computer right into the projector RS232 port if needed, usually with USB to DB9 RS-232 adapter.

xc420 Posted April 5, 2019 Share Posted April 5, 2019 In the driver wizard HEX codes require a '$' in front to signify that it is hexidecimal. Here's what I think the ON and OFF commands are: 7E 30 30 30 31 20 31 0D ON 7E 30 30 30 30 20 30 0D OFF So for Control4 : $7E $30 $30 $30 $31 $20 $31 $0D ON $7E $30 $30 $30 $30 $20 $30 $0D OFF Quote Link to comment Share on other sites More sharing options...

luminenterprises@gmail.com Posted April 5, 2019 Author Share Posted April 5, 2019 Thanks for your input on the RS232 codes. I think I've figured out the coding. I'll let you know how bench testing goes. Quote Link to comment Share on other sites More sharing options...
alanchow Posted June 28, 2021 Share Posted June 28, 2021 Old topic but i created a completely universal driver for Optoma projectors with bi-directional control and feedback via IP and RS232. Tested on multiple projectors and it works so well. T Andrew luecke 1 Quote Link to comment Share on other sites More sharing options...
