Projector Recommendations Needed
« on: August 16, 2015, 09:06:49 AM »
First of all thank to all that have contributed to this.Last year when i found out about the FPP, this obsession grew.   I am going to wade into the whole of video this year.  Just a simple video .mp4 clip in a couple of our sequences on the garage door 16'x10'.  I currently have 2 old projections that i have been playing with, an old epson and a NEC either with RS-232.  I am looking for recommendations on a new projector with shutter control thru pjlink or at least controllable via FPP so i can blank the projector during times it is not used in a sequence. Any one have a recommendation for 2800-300 lumens?

Several of us have purchased this projector.

We already have a projector Control Plugin that supports this unit as well.

Which projector would the plugin control? Just this one?

Thanks

The plugin was design to support any projector that uses rs232 commands. All we need is the command set from the vendor and we add the desired commands to a configuration from. We currently support BenQ W770ST and BenQ PB7200.

But how do you connect the Pi to the projector for this function?  Rs232? Does it goes through the hdmi?

USB to RS232 adapter and then a serial cable.
Can you send a picture of your projector's serial port?

example of a usb cable. Depending on your version of Pi you may also need a Powered USB Hub.

This is the one I just got.

Optoma H181X Full 3D 720p 3200 Lumen DLP Home Theater Projector with 2 HDMI Ports https://www.amazon.com/dp/B00N9E01WG/ref=cm_sw_r_awd_B3F0vb6CXPGXG

Can it be supported?

Thanks

I see a serial port so all we need is the command protocol for that projector.

I'll see if I can find the protocol document on their website.

I found the document, I'm pretty sure we can control it. We will need your help to test is as we don;t have this model projector.

Thank you all!  Just ordered it. I went with the BenQ.  No need to re-invent the wheel if you already have the plugin for it. Can't wait to get it and start testing.

I updated the plugin with the codes for the Optoma H181X projector. I have not been able to test it because I don't have that model. You will probably need a 9 pin null modem cable to go from the USB converter to the projector.
http://www.amazon.com/SF-Cable-Null-Modem-RS232/dp/B006W0I3BA/ref=sr_1_1?ie=UTF8&qid=1440383495&sr=8-1&keywords=9+pin+null+modem+cable&pebp=1440383495712&perid=0P5DWXPH2MYV110QDH43

I need to work with Ben and Captain to get the plugin updated in the next push.
