Operating Your VP-23RC Figure 17 shows a common setup for the VP-23RC in a media room. An overhead projector and screen, speakers, lights; and a cabinet with a DVD and a VCR inside, are all controlled via the VP-23RC. The presenter’s laptop is located on the podium (also connected to the VP-23RC), alongside the VP-23RC.
Operating Your VP-23RC 9.3.1 Operating the Media / Room Controller In the following example1, illustrated in Figure 18, the VP-23RC is labeled2 with specific functions and each button is programmed3 to perform several tasks4 as defined in Table 10. Each button may be assigned with up to 15 commands.

Operating Your VP-23RC If you want to stop a macro sequence, press and hold that button for 5 seconds. The sequence will come to an end. You can resume operation by pressing any button1. The unit will carry out the macro sequence commands from the beginning. 9.3.4 Turning the Light of the Backlit Buttons On and Off When the room is darkened, the buttons can be illuminated for convenience.
Operating Your VP-23RC Each pressed button illuminates1, indicating selection and outputting of that video and audio source. If a button includes a macro sequence, it will be executed when pressing that button.

Operating Your VP-23RC (I) When pressing button 2 under the VGA/UXGA-AUDIO SELECTOR, the UXGA IN 2 signal is routed to the display1. The VGA/UXGA button under the MASTER AUDIO SELECTOR section automatically illuminates, and the UXGA audio signal is routed to the SPKR OUT2 and the MASTER OUT2 terminal block connectors simultaneously3.
Operating Your VP-23RC 9.4.3 The Presentation Switcher SELECTOR Buttons Macro Sequence The SELECTOR buttons can be configured to execute a sequence of commands (a macro) in a similar way to the Media / Room Controller buttons (see section 9.3.1) so that when a SELECTOR button is pressed, it will first perform the switching action and concurrently carry out the macro. The example in Figure 22 illustrates a macro sequence that can be programmed to a Presentation Switcher SELECTOR button.
