Timer is Running
This is a general countdown timer, not to be confused with the more advanced timers found in Powerpoint, where time can be set for each individual slide.
Like many business/educational projectors that offer 3D, this Casio supports limited 3D formats. Let's say 3D capabilities are limited. Field sequential is supported (60/120hz). 3D is available only on S-video and composite video. Also you can use analog RGB (with downloadable software). No 3D on HDMI or component video. And no support for Blu-ray 3D which only works on HDMI.
All considered, if you need 3D, be sure that this Casio will support the format, and the source types you will be using. Note that while most DLP projectors do support 3D, some of them do support it over HDMI, and even support of frame packing which is used by Blu-ray 3D. A number of ultra short throw projectors do not support 3D at all, including those using 3LCD technology.
This Casio Projector, as noted supports wired and wireless networking. What also needs to be mentioned is that it supports the protocols used by four major network infrastructure type companies. The XJ-UT310WN supports Crestron, AMX, Extron and SP.
This allows for remote monitoring and control, push notifications and a host of other capabilities that those systems support, in their capacity to control a fleet of projectors across a corporation or a school district.
As already mentioned you can do annotation and interactivity with an app, but you can also present off of devices hooked up to the Casio through a local area network, wired, or wireless.
In addition to being able to do presenting over the network, you can also control the projector over the network, taking over command and control functions of the projector.
The Casio supports presenting from computers over USB as well as HDMI and the other interfaces. The manual documents how to set up USB presenting.
As you would expect for a projector that obviously targets the education market as well as business use, the UT310WN does offer closed captioning, which is essentially mandatory for projectors used in classrooms.
With the built in file viewer the Casio allows you, to show images and videos either from computers or USB thumb drives and other USB sources.
There's another option too. The Casio has internal memory so you can upload files to present. The projector has 2 gig of internal memory to support file viewing.
The files supported by the XJ-UT310WN are as follows. For still images: JPG, GIF, PNG and BMP. Clear background images (i.e. PNG files) come out with black backgrounds.
On the video side of things, supported formats are AVI, MOV and MP4.
In addition, PDFs, and presentation formats ECA, and PtG are supported. The Casio's documentation describes how to convert Powerpoint presentations to ECA or PtG. I did not try to do this. Unlike some projectors that have built in file viewers, the Casio lacks "Microsoft Office Suite support, where you would be able to simply directly feed the 310WN a Word document, an XLS or XLSX format spreadsheet, or a .ppt (Powerpoint).
Too often projectors with file viewers do not support AVI or MOV formats which I consider a definite limitation. One other note, there are maximum resolution limits on some of the image file formats.
24/7 Operation sounds obvious, but often with the few projectors that are designed to work 24/7, there are some qualifications. In the case of the Casio, it needs to be powered down, at least briefly, once every 24 hours. Since 24/7 operation is typically for 'digital signage', or use in some specialty operations, a projector doing that is typically hooked up to a network where command and control can automatically take care of the daily shut down, and power up cycle.
AutoRun runs "presentations" off of a folder called AutoRunC stored on the projector (part of its File Viewing capabilities). The Auto Run features is limited to the same file formats that we've already mentioned in the File Viewer section. Basically we're talking photos and other .jpg, gifs, etc. or movie files.
Casio is well known for its calculators. You can interface Casio's scientific graphing calculators that have USB ports. the Calculator can be connected directly to the USB A port on the projector, to display the calculator's graphic output. OK, not everyone has a fancy Casio calculator, but there would be some education applications where this feature would be a plus.
