Cable-free presentation available in CoE classrooms

All 50 College of Engineering (CoE) classrooms are equipped with Apple TVs to allow the presentation of slides or other content without physically plugging-in a device. The type of connection supported, called “AirPlay,” is built into Apple devices including laptops, iPhones, and iPads. You do not need to be on a particular wireless network for this to work. Apple provides some instructions on how to use AirPlay:

AirPlay video from your iPhone, iPad, or iPod touch

Use AirPlay to display video from your Mac on an HDTV

What if you are not using an Apple device? CAEN offers licenses for a utility called “AirParrot” to instructors using Windows-based computers and tablets in CoE classrooms. Note that it is necessary to connect to a special wireless network called “CAEN-Presenter” before AirParrot will work with any device. This network requires a password, which we can provide on request.

Why might you consider using wireless to display? One advantage is you do not need any special adapters, which may be needed to connect certain devices to the room’s HDMI or VGA cables. Also, if you have a tablet computer, wireless frees you to walk the stage and annotate in real-time, or even pass the device to a student to demonstrate a solution if desired.

What are the steps to get connected? It’s pretty simple. Just select the “Apple TV” source on the room’s touchscreen panel. Then connect your device to the AirPlay destination named for the room number, for example, “Dow 1013 Apple TV.” To ensure the connection to the display is coming from inside the classroom, a 4-digit code will be shown on the screen, and your device will prompt you for this code to enable the connection.

The big question: Is this all reliable? The wireless connection is typically very reliable, however it is possible that interference from other devices can cause a disconnection. CAEN is working to minimize this by relocating antennas and upgrading hardware as needed. If you run into any problems with wireless display, let us know at caen@umich.edu. A backup option is to use the wired connections at the lectern, and we are available to advise on what adapters, if any, would be needed for your device.

If you would like to meet with CAEN staff in a classroom to go over the process for getting connected, or if you have any other questions about presenting over a wireless connection, contact us anytime at caen@umich.edu.
