Figure 4 shows the RC-8IRbuilt into a podium that is located in a lecture auditorium. An overhead projector and screen, speakers, lights; and a cabinet with a VCR, a DVD and an amplifier inside, are all controlled via the RC-8IR. The presenter’s laptop is located on the podium, next to where the RC-8IRis mounted. It is also controlled by the RC-8IRand is used for presentations, slide shows and so on.

1 The second RS-232 port can be used to control another A/V unit or an LCD

2 Connected via the IR emitter cable. IR OUT1 and IR OUT2 can each be connected to identical machines and still be controlled separately

3 Each IR connector can control two different machines via a dual emitter cable. For example, a DVD player and a document camera could be connected to the same IR connector (not shown in Figure 3)
