Introduction About the SW6 VGA Audio Switcher The SW6 VGA Audio (SW6 VGA A) (figure 1) is a 6-input, 1-output audio/video switcher housed in a rack mountable, 1U high, full width metal enclosure with internal, universal, 100-240 VAC, 50/60 Hz power supply.
Installation and Operartion Mounting the Unit C Installation and service must be performed by authorized personnel only. Mounting instructions For optional rack mounting, mount the 1U high, full rack width switcher on either of the following rack shelves: The 1U high, full-rack width unit can be placed on a tabletop, mounted on a rack shelf, or mounted under a desk or other furniture.
Installation and Operartion, cont’d Under furniture mounting If desired, mount the SW6 VGA Audio under a desk or other furniture (figure 2-2) with the optional MBU 129 under-desk mounting bracket (part #70-219-01), as follows: 6. Insert #8 wood screws into the four pilot holes. Tighten each screw into the mounting surface until just less than 1/4” of the screw protrudes. 7.
Installation and Operartion, cont’d Audio connections L 1 R L 2 R L 3 R L 4 R L 5 R L 6 R L See figure 2-6 to wire a connector for the appropriate input or output type and impedance level. High impedance is generally over 800 ohms. R Audio Output connector — Connect a balanced or unbalanced stereo or mono audio device to this 3.5 mm, 5-pole captive screw connector. Connectors are included with each switcher, but you must supply the audio cable.
Installation and Operartion, cont’d Operation e Controls and indicators Auto button — Use this button, with the Mode button, to manually turn auto switch mode on. Auto is a secondary function of the Input 3 button. 2 and < buttons — Use these buttons to increase or decrease f > the selected input's audio gain or attenuation. These buttons are secondary functions of the Input 5 and Input 6 buttons.
Installation and Operartion, cont’d Switch modes Audio level control The SW6 VGA Audio switcher operates in manual or auto switch mode. • • Manual switch mode — Input selection is done using Input buttons 1 through 6 on the front panel or through the rear panel Remote connector (contact closure or RS-232). Auto switch mode — The switcher automatically selects the highest number input that has sync pulses available. Input selection by the front panel switches or through the Remote connector is blocked.
Installation and Operartion, cont’d Resetting all audio levels To reset the audio level to 0 dB for all inputs, press and hold the Audio Configuration/Save button. The Audio Configuration/ Save LED begins to blink after approximately 1 second. Continue to hold the button for approximately 10 seconds until the LED turns off. All input audio levels are reset to 0 dB.
Remote Control The SW6 VGA Audio switcher’s rear panel Remote connector (figure 3-1) can be connected to the serial port output of a host device, such as a computer or control system, to an Extron IR 102 Kit Universal Remote Control, OR to a remote contact closure device. Remote coontrol of the switcher is via Extron’s Simple Instruction Set (SIS™), Extron’s Windows®-based control program, the IR 102 Kit, or a contact closure device.

Remote Control, cont’d Windows®-Based Program Control The Windows-based Extron Universal Switcher Control Program, which communicates with the switcher via the Remote port, provides an easy way to configure and operate the SW6 VGA Audio switcher. The program is compatible with Windows 2000 and Windows XP or higher versions. Installing the software The program is contained on the Extron Software Products CD-ROM, disk B. Install the software as follows: 1. Insert the CD-ROM into the drive.
Remote Control, cont’d Contact Closure Remote Control The Remote connector also provides a way to select an input to the switcher using a remote contact closure device. Contact closure control uses pins on the Remote connector that are not used by the RS-232 interface. Figure 3-5 shows the contact closure pin assignments.
