Installing on a Rack 5 Installing on a Rack This section describes what to do before installing on a rack and how to rack mount1. Before Installing on a Rack Before installing on a rack, be sure that the environment is within the recommended range: How to Rack Mount To rack-mount a machine: 1 Attach both ear brackets to the machine. To do so, remove the screws from each side of the machine (3 on each side), and replace those screws through the ear brackets.
Connecting an XGA / Audio Switcher 6 Connecting an XGA / Audio Switcher To connect the VP-81xl1, unit, as illustrated in Figure 4, do the following2: 1. Connect up to eight VGA/XGA computer graphics sources to the HD15F INPUT connectors (from 1 to 8). 2. Connect the balanced audio sources (see section 6.1) to up to eight INPUT terminal block connectors (not shown in Figure 4) 3. Connect the OUTPUT connector to a VGA/XGA acceptor (for example, a projector). 4.

Operating Your XGA / Audio Switcher 7 Operating Your XGA / Audio Switcher You can operate your XGA / Audio Switcher, whether it consists of a single VP-81xl/VP-161xl/VP-321xl unit, or of a set of VP-81xl/VP-161xl/VP-321xl units, via the following: The front panel INPUT SELECTOR buttons, as section 7.1 describes Remotely, by RS-485 or RS-232 serial commands transmitted by a touch screen system, PC, or other serial controller Remote contact-closure switches (see section 6.
Operating Your XGA / Audio Switcher INPUT SELECTOR buttons 1 on the second and third units are inactive. You cannot connect INPUT 1 on the second and third units to an independent source because INPUT 1 on the second unit is connected to the OUTPUT on the first unit and INPUT 1 on the third unit is connected to the OUTPUT on the second unit. INPUT SELECTOR buttons marked 1 to 8 on the first looped VP-81xl unit operate INPUTS 1 to 8, respectively.
Operating Your XGA / Audio Switcher 7.1.3 Using the Audio-Follow-Video (AFV) / Breakaway Modes By default, a VP-81xl/VP-161xl/VP-321xl unit, or set of units, switches in true audio-follow-video mode in which all operations relate to both the video and audio. Both the VIDEO and the AUDIO buttons illuminate in this mode. 7.1.3.
