Introduction
This page explains what you'll need to know to use the ViewSonic PJD6352 projector on the Siemens Skyra 3.0T MRI scanner in NHB. This projector was installed 22 July, 2019, and replaced the PROPixx projector that had been in use for several years previous. This projector supports HDMI, mini-DP (aka mini-DisplayPort), and DL-DVI (aka Dual Link-DVI) inputs from laptops. The projector is turned on and off using a web interface that can be accessed from most computers connected to the campus network (via Ethernet or WiFi).
If this is your first time using the new projector, start with the section titled, "Things to Know Before Before Configuring Your Computer to Use the Web Interface."

Turning Projector On and Off
1) Open a browser that has Adobe Flash installed (see instructions above), and go to http://projector.biomedimaging.utexas.edu/crestron.htm. If that doesn’t work, use http://172.16.154.231/crestron.htm instead. Once loaded, we recommend you bookmark this page for easy access in the future. You may see a page that looks similar to the one here, asking for permission to run Flash. If you see this, click the icon to give permission.
2) The interface will ask you for a password. The password is the 4 digit PIN, 0240. This happens to be the suite number for the BIC in NHB – 0.240. Just omit the decimal point in the number.
3) Click the Power button in the top left of the screen to toggle the power on and off.
4) you may see a Warming Up dialog when you turn on the projector, or a Cooling Down dialog when shutting down. This is normal, but please do not click anything while either of these dialogs are displayed. This will decrease the bulb life and could actually make it fail. A note about the cooling down phase- You do not need to keep this web page open until the cooling down is completed. That process will continue whether or not the web page is open, and it could take anywhere from a few seconds to several minutes, depending on how long it takes to cool down the bulb to it's nominal temperature. However, since it could take a while, it probably makes sense to keep the projector on if another group is going to use it immediately after your scan. warm up-cool down cycles also shorten the bulb's life.
VERY IMPORTANT: Do not click any other buttons on this page. You do not need any other options here. Only use this page to turn the power on and off.
Selecting the Correct Input on Video Switch
1) First determine which input you will use: HDMI, mini-DP, or DL-DVI. Once you have, select the appropriate input cable, and plug it into your laptop. Note that each cable is labeled with the input name selectable on the video switch - HDMI goes to the input labeled HDMI 1, mini-DP goes to HDMI 2, and DL-DVI goes to HDMI 3.
2) Select the input you need on the face of the video switch. The names (HDMI 1-4) are touchable buttons. For example, if you are using the HDMI cable, touch "HDMI 1" on the face of the switch, etc.
3) Ensure that the resolution selected on the video switch is 720p (even though you're going to force your computer to use 1024x768 in the next step).
4) Configure your laptop to send 1024x768 at 60Hz to the secondary display.
Things to Know Before Configuring Your Computer to Use Projector's Web Interface
- You will use a web interface to turn the projector on and off.
- The computer you use to control the projector does not have to be the laptop you use for stimulus.
- The projector interface uses Adobe Flash Player, and that is only supported on Windows by Internet Explorer and Firefox; on Macintosh, it is supported by Safari and Firefox. On both platforms, Firefox is strongly recommended. The configuration instructions below explain how to install Adobe Flash on your computer, If you already have Adobe Flash installed, you do not need to complete those steps.
- No mobile devices support Flash. You must use a system that runs Windows or a full OSX Mac (no iOS).
- This configuration procedure only has to be performed once on the computer you will use to control the projector. After that, no further updates are needed.
