The procedure for checking out the department projectors is as follows:

1. Ask Wilhelmina (in LeFrak 2181) for the sign-out sheet for the projectors.

Two projectors are available for the department's use; both are similar in features and compatibility. Both also have a variety of cables and should be able to connect to Mac, PC, and Unix computers as well as VCRs and other video signals. If you're uncertain of your system's compatibility needs, please submit a geog-help in advance.

2. The sign-up sheet will list availability for both projectors for the next several weeks. While you will be able to reserve a projector several weeks in advance, you'll only be able to check out the key during the specific day that you wish to use it. Select the blocks of time that you wish to use the projector.

3. If you haven't already, please complete a Projector Sign-out Responsibility Agreement form (extra copies are in the back of the notebook) and place the completed form in the back of the notebook.

4. Be advised that the Front Office closes at 4:30 pm each day; if you have to use the projector for an evening session you will be responsible for returning the key to Wilhelmina's mailbox in the mail room after you are done with it.

5. In taking the key, you are assuming the responsibility for the safeguarding and proper use of the projector for the times in which you have reserved it.

6. The projectors are secured in the AV closet on the side of the Seminar Room (LeFrak 1124). The key that you check out from Wilhelmina can be used to unlock the security cable holding the projectors in place.

7. Please consult the on-line help pages or speak to a Lab Assistant if you have not used the projector before. The set-up process is fairly straightforward; however, there are a few variables to consider when using the projector in classroom settings. You are likely to use the projector in one of two scenarios: a) connecting a laptop to the projector, with or without an Internet connection, in one of the classrooms on campus; or b) connecting a projector to one of the Unix workstations in the Open Lab.

a) Connecting a Laptop to the Projector (w/Internet connection)

i. We do not at present have a laptop for checkout; however, the Department is planning to acquire one later in the school year. Until then, you are welcome to use your own laptops for presentations. Please remember that we use an Ethernet network on campus; conventional modem ports cannot connect to the Ethernet network. You'll need to purchase an additional Ethernet card for your laptop if it doesn't have Ethernet built-in.

ii. Internet connections are available in the Seminar Room (1124) and in LeFrak 2166; however, coordinating one's laptop for an Internet connection requires submitting a geog-help AT LEAST two days in advance and making (and keeping) an appointment with one of the Technical Support staff during business hours. We must configure your laptop with the TCP/IP numbers for the specific classroom you are using, and we will need advance notice if you are to need this resource.

iii. Please be advised that the Sun/Unix network available within the department is NOT directly accessible from a conventional Internet connection; therefore, any web pages or other resources which you may wish to utilize in presentations with an Internet-connected laptop must either be transferred to the laptop's local hard drive or published on the web itself (either in the /pub folder on your homespace or through a WebSpinner account or alternate Internet Service Provider); send a Geog-help for details on this procedure.

iv. If you have a Macintosh laptop, please submit a geog-help for assistance. The Macintosh platform uses a special kind of monitor adaptor; we have an adaptor of this kind but it must be asked for specifically, in advance. Please be aware that iBooks do not have video-out capability and therefore cannot interface with the projectors.

v. Plug the other end of the cable which comes from the Video In port on the projector into the laptop's Video Out port.

vi. When you turn on the projector, the video signal should be transmitting from the laptop to the projector.

vii. To disconnect everything, turn the projector off first.

NOTE: Turn the projector off immediately when done with the presentation, to give the fan a chance to cool down the projector before you unplug it.

viii. Unplug the projector cable from the back of the laptop.

b) Connecting the Projector to a Unix Workstation in the Open Lab

Essentially, the Projector is nothing more but a fancy monitor, and interfaces with the Unix workstations through the same sort of cable.

Usual connection:

     [Workstation] -- [Monitor]

     Unix Workstation's Video Out port --> Monitor cable

Projector connection:

                   a)             b)
     [Workstation] -- [Projector] -- Monitor

a) Unix Workstation's Video Out port --> Projector
Cable connected to the Projector's Video In port
b) Projector's Video Out port --> Monitor cable (optional)

i. Unplug the monitor from the back of the Unix workstation (you do not need to shut down the workstation to do this). Depending on the sort of workstation you're using (Ultra 10 vs. Ultra 10/3D) there may be a special monitor adaptor on the back of the existing monitor cable. You may wish to plug the monitor cable into the Video-out port on the Projector if you wish to see the projected material on the monitor you're using; if this is the case, then disconnect the monitor adaptor from the monitor cable before plugging it into the projector (this should be self-evident, as it won't otherwise fit). Keep the adaptor plugged into the back of the computer, as you'll need it to connect the projector cable to the workstation.

ii. Plug the other end of the cable which comes from the Video In port on the projector into the Unix workstation's Video Out port [or the monitor adaptor, if needed] (wherever the monitor cable used to be attached).

iii. When you turn on the projector, the video signal should be transmitting from the Unix workstation to the projector.

iv. To disconnect everything, turn the projector off first.

NOTE: Turn the projector off immediately when done with the presentation, to give the fan a chance to cool down the projector before you unplug it.

v. Unplug the monitor cable (if applicable) from the projector's video out port.

vi. Unplug the projector cable from the back of the Unix workstation.

vii. Plug the monitor cable back into the Unix workstation.

8. When you're done with the projector, please return it to the A/V closet next to 1124 and secure the projector cable with the key.

9. Return the key to Wilhelmina, and sign the key back in by signing the notebook.
