A-1 What the S-RA2500 Editing System is used for
The KODAK CAROUSEL S-RA2500 is a powerful slide projector whose functions, including
the selection of individual slides, can be remote controlled via the built-in serial computer
interface (RS232C). It makes it possible for the user to escape the rigid constraints of previous
linear SLIDE programs and allows him to program tree structures.
This is one step closer to combining the interactive capabilities of a computer system with
visual slide projection techniques. The only problem is how to write suitable computer soft-
ware for the particular application. If one of the usual programming languages has to be used,
the task is generally expensive and time-consuming.
The solution to this problem is the S-RA2500 Editing System, a computer program for creating
information programs and a tool which will enable you to combine the power of the computer
and the visual qualities of slide projection in order to get your information over to the required
audience in an effective form without having to learn a programming language.
Programs written using this tool can, if required, simultaneously convey information:
-Via the screen of a PC type computer in the form of blocks of text (colour or monochrome),
-Via SLIDE projection which can use up to 16 selectable KODAK S-RA2500 type projectors
and provide familiar effects available using a SLIDE-AV technique,
-Via a printer connected to the computer. The computer provides the finished program recipi-
ent with preprogrammed printed informative text which he can take away with him,
-Via an 8-bit control interface which can be used to drive external equipment such as lighting
equipment, film projectors, video recorders etc. via a suitable add-on unit referred to as the
„auxiliary box“.
The logical structure of the information programs which are written can be interactive and tree-
structured. This means that:
- Inputs from the recipient can be requested, evaluated and used as a decision criterion for the
subsequent course of the information program.
-Inputs from a recipient concerning individual information items can be counted, stored on
diskette and thus made available for subsequent evaluation.
-Inputs from a recipient in the form of a line of text can be date and time logged, stored on
diskette and made available for subsequent evaluation.
-The time which a recipient takes to make an input can be limited (TIMEOUT). The fact that
a timeout has elapsed can be used as a decision criterion for the subsequent course of the
program in the same way as a normal input.
From the recipient’s viewpoint, a typical information program consists of a sequence of blocks
