This is an example of a normal RTC classroom equipment set-up.  According to an electronic course script ,the computer asks the trainer to load specific interactive tapes, shuttles to que the next segment, and plays only the segment then pauses the VCR.  When the VCR is paused the trainer is prompted by the Macintosh similarly to a teleprompter.  When the trainer has completed the required activity (hands-on activity, discussion, workbook activity, demonstration, etc.) , the trainer hits the "ENTER" key to progress.  Each time the trainer hits the "ENTER" key, the exact time is recorded in the electronic script.  When the class is complete, the script is electronically transmitted to the Fort Lauderdale Office through the RTC server computer for evaluation and processing.  Each classroom where Seagull Training is to take place must be equipped with equipment meeting the specifications that follow:

1. Macintosh Computer
    
   The presentation system can use any Macintosh Computer except a Macintosh Plus, Lisa, or 512k machines.  Since the speed and volume requirements of the Seagull software are minimal (8 megahertz processor speed and 4 megabytes of ram), Seagull has found that using less expensive, used computers is both acceptable and economical.  The least expensive classroom MAC is the Macintosh SE.  Seagull has several sources of these computers at quite reasonable prices, but you don't need to acquire your classroom computers from or through Seagull.  Should you acquire your own computers, they will need to be shipped to Seagull in Fort Lauderdale to be programmed.
    

   LANC Cable

   This cable has to be specially made for Seagull's Interactive Video Presentation System.  They may be acquired only through Seagull.

   Sony LANC Control 8MM VCR

   LANC is a protocol for the computer or other peripheral to communicate with the VCR and vise versa.  Many Sony 8MM VCR's have LANC control capabilities.  You can determine if a VCR is LANC controllable by looking at the back of it.  You should see one of the following:

   A blue circular female plug the size of a mini earphone jack.

   The letters "LANC"

   The Letter "L"

    

   Antenna Cable

   This cable carries the video and audio signal from the VCR to the TV.  It is available from Radio Shack or most stores that sell Televisions.  One should come with your VCR.  The cable should be rated at 75 ohms.  This cable is not required if you are using a video monitor instead of a TV.

   Common Television or Monitor
    

   You will be required to supply a Television or Video Monitor for each classroom.  The picture tube should be as large as possible, but, in no event, should the diagonal measurement be less inches than the number of students you anticipate in your largest classes.  If you anticipate classes in excess of 27 students, you may find that it is less expensive to use multiple televisions.

   To set up multiple TV's to operate from the same source, you will need a 75 ohm signal splitter available at Radio Shack or Home Depot.

   If you elect to use a video monitor (much clearer picture), you will need two RCA or phono cables, one for video and one for audion.  The cables should be installed between the audio out and video out of the VCR on one end, and the audio in and video in on the back of the video monitor.  RCA cables are available at Radio Shack and Stereo stores.

   Farallon Adapter
   A Farallon Adapter should be attached to each end of you network cable.  In the classroom, the adapter plugs into the printer port on the back of the Macintosh Computer.  The line runs to other classrooms and to the RTC server computer.  Once properly installed, the network will accommodate the following:

   Sending messages, documents, and files between the classroom, the RTC server computer, and the Fort Lauderdale Home Office

   Electronically updating your courses

   Sending your completed documentation for courses to Seagull

    
   Farallon Adapters are available from Seagull, CompUSA, and other computer stores.  Some Office Depots carry them.

   Network Cable

    The network cable used is the same as common telephone cable available from Radio Shack or Home Depot.  It is a four wire cable with standard telephone plugs on each end.  Should you use a union to join two cables, be sure that the union is a four wire union.  Many unions only pass the signal form the two center wires.  Telephones only use two of the four wires.  Unions are also available from Radio Shack or Home Depot.

   The cable should be run to all classrooms and to the RTC server computer.
