Sharp Projector Module Help!

dmenke

I'm working on deploying 30+ sharp projectors in classrooms here at WIU, using XG-335XU and XG435XU, and I have them working (mostly) and talking to my RMS server. I'm having a few issues that I'll describe below:

1. The lamp hours is reporting back the percentage of lamp life left (currently 99%). Earlier projectors using the same module reported the actual lamp hours. How can I get hours on the newer projectors?

2. Aspect ratio cycling/switching seems buggy. I know some ratio options are not available to certain signals, but I have an Elmo doc camera that will not switch to any different ratios, regardless of the command sent to the module. The demo stuff seems to work OK, but I an not experienced enough to know what is happening with the demo code.

3. If I want to send a string directly to the projector, is it better to use the passthrough command, or send a string right to the device, bypassing the module altogether? What are the pros and cons to doing this?

Thanks!

Don't bypass the module if you have any choice about it. They generally have a queue of some kind internally that handles pacing and sequences, and if you send directly to the device you could mess something up. Your action could also generate a response that the module will interpret wrongly because it was expecting something else. If the module has a passthrough, use it; of course, if it doesn't, you have to just take your chances.
