[. . . ] VSX41 Video Switcher Operation Manual ® Biamp Systems, 10074 S. W.

Passive switching allows the VSX41 to be used as either a switcher or router, and for either video or audio signals. [. . . ] To install the receiver, first take off the front cover by removing the four screws. Mount the receiver to wall or other surface, using the two screw holes on the back cover (screws not included). The receiver should not be mounted in direct sunlight, or pointed directly at fluorescent lighting. For best results, there should be an unobstructed lineof-sight from transmitter to receiver. The receiver may be wired up to 2000 feet from the VSX41, using 2conductor shielded cable (not included). Route the cable through the access hole on the bottom of the receiver. The three screw terminals inside the receiver ("GND", "IR2", & "IR3") directly correspond to the Remote 1 and Remote 2 terminals on rear panel of the VSX41. Use the two conductors to connect "IR2" to "IR2" and "IR3" to "IR3". The LED indicator inside the receiver (and the IR LED indicator on the VSX41 front panel) will light whenever infrared information is detected. NOTE: The Infrared Receiver includes a "Remote Translator", which allows remote control via third-party controllers (instructions included with receiver). It can provide up to 40 buttons (12 more than standard remote controls), which are support by some ® other ADVANTAGE products. The VSX41 itself only supports 4 buttons (Channel Select), but it will also pass commands on to other Advantage products which have been connected to the Remote Output (see Applications on page 7). The Remote Interface Kit is a tested circuit board assembly, which includes two wiring harnesses. The circuit board connects to the VSX41 in exactly the same way the External Infrared Receiver does, using 2-conductor shielded cable (not included), and may be wired up to 2000 feet from the VSX41. The three screw terminals on the circuit board ("GND", "IR2", & "IR3") directly correspond to the Remote 1 & Remote 2 terminals on the rear panel of the VSX41. Use the two conductors to connect "IR2" to "IR2" and "IR3" to "IR3". The circuit board is 2. 27"W by 2. 65"H, with four mounting holes (2" centers) and #6 mounting hardware provided. Complete instructions are included with the Remote Interface Kit. Logic Inputs: The 9-pin Subminiature D (female) connector on the rear panel of the VSX41 provides four logic inputs and their related ground. Logic Inputs allow remote control of the VSX41 Channel Select switching function via external logic output circuits, contact closures, or active driver circuits. When nothing is connected to a Logic Input, an internal pull-up resistor keeps it at a "high" idle state. The Logic Input is activated when its input goes "low" (less than +2VDC). A Logic Input is controlled in one of three ways: 1) Use an NPN style "open collector" logic output from an external device (such as an ADVANTAGE AGII or DRC4+4) to short the Logic Input to ground. [. . . ] An ADVANTAGE 301 receives input signals from the paging sources, and sends a single output to the VSX41. The 301 may be assigned so signal present in Channels 1 & 2 causes 15dB ducking of Channel 3 (example: mic priority over telephone). (When ® using the VSX41 as a "router", the Output connector is used as a single input. ) PRECEDENCE CMA60s provide power for the four ® paging zones. An ADVANTAGE DA28R receives input signal from a background music source, and distributes that signal to the Channel 2 input on the four CMA60s. [. . . ]
