Using your laptop

It's often more convenient to use the TV as an external monitor for your laptop. There's an HDMI cable extending from beneath the TV screen that you can plug into any laptop with an full-size HDMI socket. There's a 3-way HDMI switch for adapter cables for other port types; ask WilliamSeligman if you need one.

Polycom (for H.323)

The Polycom Videoconferencing system can be used for point-to-point conferences with other Polycom systems. You will need the remote controls for the television (TV) and for the Polycom.

  • Turn on the TV with the TV remote (red button, upper left-hand corner).
  • Press INPUT on the TV remote until the text reads INPUT2A in the upper right-hand corner of the screen.
  • The Polycom is often left on, because it takes so long to start up. If there is a yellow (standby) or blue (active) light on the camera, it's already on.
    • If it's off (no light shows on its camera) turn it on with the Polycom remote (upper right-hand corner, above the display):
    • The sensor for the remote signal is located on the camera on south wall of the room to the left of the TV; point the remote at the camera.
    • It takes 2-3 minutes for the V/C to start up. Give it time. Eventually the blue light on the camera will turn on, and the TV screen will display the Polycom logo.
  • Once the Home display shows up on the TV screen, use the arrow keys on the remote to highlight "Place a call." Push the central button on the remote to select this option.
  • Enter the IP address of the remove Polycom system using the remote's number keys.
  • Press the "Call" button (green button, middle left-hand side).
  • If you have to use the keypad during the conference (e.g., to enter a PIN number), first press any key on the keypad. The keypad icon will appear on the lower right-hand corner of the screen. Then you can use the keypad to enter numbers or the # symbol.
  • When you are done, turn off the TV with the TV remote. You can leave the Polycom on.

Notes:

  • You have to know the IP address of the remote Polycom unit; for example, the IP address of video.phys.columbia.edu is 128.59.170.158.
  • Other sites with Polycom units cannot remotely connect to the one at Nevis, since it's on a private network. We can dial out, they can't dial in.

The Polycom microphone

The microphone is usually located on one of the central tables. It's the smaller of the two flat three-panel microphones.

Problems

The most frequent problems encountered so far:

  • If no one can hear you, check that the mute button on the microphone isn't pressed. Both the camera and the microphone show a red light if "mute" is on.
  • If there are video problems, try turning the V/C off and on again. Sometimes leaving the unit on for days at a time can cause a configuration error.

To change the V/C display

To change which screen(s) are displayed on the TV, press the Display button on the upper left-hand side of the remote. Press the up-arrow button to toggle different display modes. You can toggle PIP (picture-in-picture) by pressing the Display button twice in succession.

"How do I... ?"

At this point, you know as much as I do. See the manuals at the bottom of this page.

  • If the projector doesn't automatically display your laptop's screen, press the Input button (up-arrow) on the top of the projector. You probably want this to be set to "COMPUTER1"

"Old videoconferencing system" (room 94)

The V/C system in room 94 is an older and slower version of the system in the library. Its operating instructions are basically the same as the library system.

Here is the User's Guide for the old V/C system.

The old V/C can do one thing that the newer system cannot: It can be dialed in as part of an EVO conference. Here are the instructionsf for setting this up; the IP address of the system is 129.236.252.61 = videoconf.nevis.columbia.edu.

When used in an EVO conference, the old system's video is too slow to be usable, about one frame refresh every 15-20 seconds. However, the audio quality is acceptable.

H.323 (ESnet) and EVO

How to call into an ESnet H.323 meeting from EVO:

  • Get the ESnet meeting ID; for example, 85-NEVIS (8563847)
  • In EVO, click phone icon-->Call H.323/SIP Client
  • Enter <meeting-id>@gk1.es.net; e.g., 8563847@gk1.es.net
  • Select 768 kbps
  • Click connection through Panda

"Old videoconferencing system" (room 94)

The V/C system in room 94 is an older and slower version of the system in the library. It's operating instructions are basically the same as the library system.

Here is the User's Guide for the old V/C system.

The old V/C can do one thing that the newer system cannot: It can be dialed in as part of an EVO conference. Here are the instructionsf for setting this up; the IP address of the system is 129.236.252.61 = videoconf.nevis.columbia.edu.

When used in an EVO conference, the old system's video is too slow to be usable, about one frame refresh every 15-20 seconds. However, the audio quality is acceptable.
