                            Video Conference Procedures
                                    Terminology
Heated data jack: A wall connector (Type RJ-45) activated (heated) for computer networking.
Data jacks and phone jacks are identical in appearance except that phone jacks can ring which
draws voltage that would fry a Polycom unit plugged into it at the time.

POTS Jack: Plain Old Telephone System jack (RJ-11) with two or four wires. These are used
only for analog phones and FAX machines, though an RJ-45 Jack can be reprogrammed to be
analog and an RJ-11 wire plugged into it.

Polycom cart: The videoconference equipment package including Polycom (video-
conferencing camera and microphone combination used at OHSU for teleconferencing), monitor,
and associated equipment. The Polycom should stay on the cart.

Videoconference (VC): One type of teleconference (the other is voice) describing a two- (or
more-) way interactive video connection between compatible stations . Conferences may be
basic (two groups talking to one another); bridged (three or more groups talking to each other);
or presentations (one speaker and multiple audiences, often sharing data).

IP: “Internet Protocol”. A widely used method for sending data over networks. When the
Polycom starts up, a green IP icon signifies the jack is hot and an IP address has been obtained.

IP address: The four-part numeric location assigned to a jack on a permanent (static IP) or
dynamic (DHCP) basis. All addresses at OHSU are of the form 137.53.x.x. The static IP address
of the VGTI Polycom is 137.53.17.98.

E-164 address: Usually the phone number to reach the primary operator of a Polycom unit,
which is used to locate a Polycom regardless of which jack it is plugged into. The E-164 of our
Polycom is 5034182733 (the extension in the VGTI library).

Data sharing: Peer-to-peer networking between laptops at the two ends of the teleconference
using a program called Timbuktu (see Data Sharing procedures, page 14).

Scan converter: The Corioscan Pro unit used to connect laptop computers to the video cables
that carry a signal to the ceiling-mounted LCD projector. The Corioscan can also convert a
computer (VGA) image to an analog (NTSC) signal to be used by the Polycom unit.

Bridged conference: A videoconference allowing three or more sites to connect together.
Bridges should be arranged at least two weeks in advance by calling John DeSocio at 4-7503. A
bridge address is the 7-digit number consisting of the year and bridge number, e.g. 2002001.

Mic pod: A Polycom microphone unit that picks up voices from about a 10-foot radius. Mic
pods should be set down on a flat, vibration-free surface away from equipment fans and at least
10 feet from monitor speakers. Two pods can be daisy chained together, but not separated by
more than 10 feet of cord. Mic pods can be muted by pressing the center button (turning it red).


                                                                         Rev: 10/2/02 2:34 PM

                                 Basic videoconference

    Advance arrangements

Note: Before setting up a video call, arrange and exchange the following information with the
individual in charge of the Polycom at the other end of the call:

   1. Room numbers for each side of conference

   2. Room reservations (allow 1/2hr for setup; each room must have data jack for Polycom)

   3. Polycom reservation (including time for set-up)

   4. Phone or pager numbers of Polycom operators (see “Whom to Contact” page 3)

   5. Polycom IP or E-164 addresses and who will call whom to begin the call or reconnect

   6. Arrange to e-mail or mail any documents that will be used in the conference.

    Polycom setup

1. Position Polycom. Move cart to convenient location, usually near corner of conference table,
   next to storage closet and close enough to data jacks and power.



2. Check power. Verify that monitor is on
   (screen may be dark, but red LED, near right,
   will be lit) and Polycom is off (rocker switch
   position, far right).


3. Check data. Ensure data cable is plugged into
   labeled network jack (near right) and into
   orange outlined jack in back of Polycom (far
   right).




                                                                       Rev: 10/2/02 2:34 PM

   drivers are required. To use remote, turn the computer on, load a PowerPoint presentation,
   and switch display to full screen mode. Press top (largest) button to advance slides, middle
   button to back up a slide, and bottom button for a (low-powered) laser pointer.

4. Connect video. (a) Attach VGA cable (labeled “computer” and stored on Polycom cart), to
   the computer VGA video output of PowerBook or PC. (b) For an i-Book, use white display
   adapter (stored with the i-book in Room 1216). Turn on computer after equipment is
   connected.

     connected.

5. Set screen resolution. (a) on a Mac PowerBook or i-Book, (i) click on the control strip or
   select “Monitors” from the Control Panel and (ii) choose “millions of colors” and resolution
   of 1024x768. (b) in Windows, (i) right click on desktop for a context menu and select
   “properties”; (ii) in Display Properties dialog, click on “Settings” tab (upper right) and
   choose “1. Default Monitor” for the display, Colors “True Color (32-bit)” and move slider
   for Screen area to “1024 by 768 pixels”; (iii) click “OK” twice to resize the desktop then
   “Yes” to keep the change.

6. Turn on video mirroring. (i) Plug in video cable to an i-book and mirroring starts
   automatically. (ii) for a PowerBook, plug in video cable and with monitors control panel,
   drag window 1 over window 2 to set up mirroring. (iii) on laptop, press function key
   combination with a monitors icon (Usually hold down function or “fn” key while pressing
   F2, F3, or F4) to toggle external projection on and off. Some PCs may have three toggle steps
   for internal, external, and both).

7. Laser pointer. The brightest laser pointer is part of the projector remote (use button labeled
   “Laser”). The second brightest is the laser pen, stored on the Polycom cart; however, the
   battery contacts on this pen are poor and may occasionally stop working. The RocketPoint
   RF has a smaller pointer, somewhat difficult to activate due to the button size, but it is
   convenient when controlling a PowerPoint presentation remotely.

8. Please clean up. After completing your presentation, (a) Press and hold the “off” button
   while pointing the remote toward the front of the projector until, on the projection screen, a
   message says projector will turn off, then return remote to the cart. Use the screen toggle
   switch to raise screen, and clear the table of belongings or trash before leaving.



      Contacting visiting speakers
1.   Request presentation file. Ask for a PowerPoint file, either for Mac or PC, and if it will be
     permissible to preload it onto one of the department laptops. Files of 10 MB or smaller can
     be e-mailed directly to us. Files larger than 10 MB must be either brought on media (zip or
     CD) or uploaded to the Sellwood server (call helpdesk at 4-2222 for getting permission and
     making arrangements).
2.   Determine presentation platform. Mac or PC? Stick with the platform the presentation
     was created on.
3.   Preview presentation. Check for artifacts or font substitutions; open presentation and edit
     format if necessary. Note: if copied from CD, read only file attribute needs to be unchecked
     to save changes.
4.   Explain teleconference procedure. (a) Remote site only sees what comes over projector
     and shows/plays on TV; (b) to feel included, speakers should ask if people at the remote site
     can hear okay and from time to time, if they have any questions.
                              Projector Troubleshooting

Symptom                Problem/Solution(s)

No projector output    Projector not working. To correct, (1) verify that projector is on (you
                       should be able to hear the fan); If image still does not show, projector
                       lamp may be burned out. For quick & dirty fix, use the portable video
                       projector (stored in room 1216).

                       Blue Projection Screen. Broken video path. To correct: (1) check that
                       laptop video mirroring is on (see step 6, above); (2) laptop firmly
                       connected to video cable (thinner of two cables); (3) video cable firmly
                       connected to scan converter input; (4) scan converter output connected
                       to the Extron cable (the fat cable); (5) Extron cable connected to BNC
                       (colored wall plate) plugs. For Q&D fix, unplug cable from scan
                       converter and plug directly into side of projector.

                       Distorted or discolored projection. Poor video connection. (1) ensure
                       all video cables connected properly to the PC and scan converter; (2)
                       check each BNC connector for a proper link. If problem persists,
                       connect directly to ceiling projector (see above)


Blurry text or pictures Image aliased. Change video resolution of screen to 1024x768

No video mirror        Projector not sensed. (1) see of computer projection works anyway; (2)
options on laptop pc   if not, try toggling Fn key on PC or opening monitor control panel of
or PowerBook           PowerBook. Q&D: data transfer (see below)

Quick and Dirty data   Burn onto CD. If that isn’t possible... (1) to move data from one
transfer               firewire Mac to another, plug in zip drive, copy presentation file onto
                       zip, the plug into department i-book and reverse process. Always copy
                       file and any accompanying video files into a hard drive folder so that
                       file does not reside on zip drive’s “desktop”. (2) For networked
                       computers, Mac or PC, use network cable to connect to wall jack and
                       copy file onto server, move cable to new computer, and copy off server.
                       For PCs, without a CD burner, connect HP CD-burner to laptop and
                       follow instructions to install drivers. Make sure to uninstall afterward.

Power saving comes     Turn off power saving. (1) For mac, click on Energy Saving control
on                     panel and move sliders to “Never”; (2) for PC, open “Screen Savers tab
                       of display properties, enter power savings, and specify “never”.

    TB2 Troubleshooting
                                            Problem: TB2 locator service not available.
                                            Solution: Check network connections, confirm data
                                            jack hot, and if problem persists, use IP to contact
                                            remote computer.
                                            Problem: Invalid log-in computer name.
                                            Solution: First, try retyping name in Step 6 (above)
                                            with careful attention to capitals and spaces. Second,
                                            if remote computer is being attended, select “request
                                            permission” or “log in as guest”.

                                               Problem: Extraneous dialog box on PC.
                                               Solution: Try cancel to get rid of box and fill in
                                               normal (step 6, above) permission window. If this
                                               fails, enter log-in computer name and password
                                               leaving Domain blank.



Problem: Slow response, particularly for
embedded movies.
Solution: Overhead for TB2 is high,
and connection will be slower, but verify
that in preferences, “Control/Look”,
section, “Hide desktop picture or pattern”
is checked and “Scan aggressively” is
unchecked
Problem: Artifacts left on screen between slides on Macintosh
Solution: if time available, remove random transitions from PowerPoint slide show

Problem: PowerPoint animations will not play (Mac or PC)
Solution: click pointer somewhere inside slide to make animation play

Problem: Speaker insists on using own computer
Solution: Ask if TB2 can be installed on that computer and uninstalled when done. (2) If not
installed, point polycom camera at screen during presentation and let the remote room view the
show on a television monitor instead of full screen

Problem: Spontaneous disconnect of computers on TB2
Solution: Check network cables, contact Chris or Jeff at MMI, and repeat connection procedure
Problem: No IP connection available for
computer
Solution: Plug into computer jack at
back of Polycom (empty jack in
illustration at right) and caution presenter
to pause between slides when advancing
them (connection will crash if they are
advanced rapidly). Restart if crash.

Problem: Speaker’s text turns out as gibberish or contains strange characters
Solution: If time available, presenter should change computer platform to match system used to
create slides. Failing that, open PowerPoint and change fonts to standard types such as Times or
Ariel.
