PVS 305SA 1 Chapter One Introduction About this Manual About the PVS 305SA Application Diagram
Introduction About this Manual This manual covers the installation, operation, and configuration of the Extron PVS 305SA PoleVault® Switcher. Throughout the manual, this switcher is interchangeably referred to as the PVS 305SA or PoleVault switcher. About the PVS 305SA The Extron PVS 305SA is a five input, two output, twisted pair, audio and video switcher with a built-in audio amplifier.
Features Twisted pair inputs — The PoleVault switcher accepts two independent, high resolution RGB video and audio signals, and two configurable inputs for either composite video or high resolution RGB signals, and audio signals, transmitted on twisted pair cable from a source up to 100 ft away. Video output — The PoleVault switcher can switch between four inputs (either four RGB or two RGB and two composite).

Installation UL/Safety Requirements The Underwriters Laboratories (UL) requirements listed below pertain to the safe installation and operation of this switcher. PRELIMINARY Important safety instructions 1. Read these instructions. 2. Keep these instructions. 3. Heed all warnings. 4. Follow all instructions. 5. Do not use this apparatus near water. 6. Clean only with a dry cloth. 7. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions. 8.
Mounting the Switcher The PVS 305SA switcher and the power supply can be mounted in the Extron PMK 550 (Pole Mount Kit) that is installed above the projector. The low profile of the PMK 550 allows it to be installed in tight spaces. N There are two models of the PMK 550 and each mounts the PoleVault switcher differently; one directly to the plate, the other using mounting brackets. If there is a need to mount the PoleVault switcher on the PMK 550, follow the appropriate method.
Installation Mounting onto the plate using brackets. N This method allows mounting and removal of the PoleVault switcher without removing the PMK 550 from the pole. 1. Remove the cover securing screws and slide the two plastic covers away from the mounting plate. 2. Install both brackets into the slot (see figure 2-3).
Wall mounting the PoleVault switcher 1. Following the instructions supplied with the WMK 100, prepare the wall and temporarily mount the base plate on the wall at the desired location. 2. Run the signal cables from the PoleVault input wallplates, control device, and the speakers to the WMK 100 location. Cables can be routed behind the walls, or through a surface raceway. 3.

Installation, cont’d Labeling the A/V Inputs Labeling and connecting the A/V input cables The RGB and composite video input ports on the rear of the PVS 305SA are color coded to aid easy identification of the input signal type. A sheet of corresponding colored labels is supplied for the installer to label the cables running from the PVT Wallplates to the switcher.
Labeling the PVT Decora face plates To help identify the input number and type of signal that RGB IN #1 any PVT Decora wallplate sends to the PVS switcher when the wallplate is installed, a series of small labels are supplied. A label identifying the transmitted signal type should be affixed to each Decora face plate (top or bottom) where it can easily be seen after installation.

Front panel operation N See the front panel image (figure 3-1) for the location of input buttons, adjustment knobs, LEDs, and configuration port. • To change inputs, select an input button, 1 through 4 (video and audio), or 5 (audio only). • To adjust audio input levels, rotate the Input adjustment knob through 43 positions in 1 dB steps (-18 to +24 dB, default 0). • To adjust VoiceLift microphone levels, rotate the MIC adjustment knob through 43 positions in 1dB steps (-18 to +24 dB, default 0).
Operation and Setup, cont’d Executive Mode (Front Panel Security Lockout) To prevent accidental or unauthorized changes to settings, the PVS switcher has a front panel security lockout (executive mode) that limits users’ access to front panel controls. When the executive mode is active, all functions are locked. To turn executive mode on or off via the front panel: 1. Press and hold input selection buttons 1 and 4 simultaneously for 4 seconds (see figure 3-2). All the input LEDs light. 2.
When adjustments to all five inputs’ sensitivity settings have been made, then adjust the amplifier level (via RS-232 only). Increase or decrease the amplifier level very slowly, if needed. N If the volume is at 100% through the MLC and the output on the speakers is too loud, reducing the amp level via RS-232 control software is recommended. This ensures that the volume will not be too loud, even when set at 100%. 7.
Operation and Setup, cont’d Amplifier level control Amplifier level control is adjusted via RS-232 or control software only. See chapter 4, “Serial Communication”, for details on RS-232 control. Bass, treble, and loudness control For optimum audio quality, the audio input levels and the bass, treble, and loudness controls must all be set up properly. Input audio levels may need to be adjusted depending on the variation of the output levels from different source devices.
PVS 305SA 4 Chapter Four Serial Communication RS-232 Programmer’s Guide Updating Firmware
Serial Communication The PVS 305SA switcher can be remotely set up and controlled via a host computer or other device (such as a control system) attached to the rear panel Control port. Alternatively, the switcher can be controlled by an MediaLink Controller (MLC) (connected to the same port) or by an RS-232 device acting through the MLC. The control device (host) can use either the Extron Simple CONTROL Instruction Set (SIS™) commands or the Global Configurator Tx Rx IR +12V program for Windows.
Error responses When the PVS switcher receives a valid SIS command, it executes the command and sends a response to the host device. If the PVS is unable to execute the command because the command is invalid or it contains invalid parameters, it returns an error response to the host.
X# = Status, 0 = off/disable (default) 1 = on/enable = Signal detection threshold 0 = off (signal level too low to detect) 1 = on (a signal of a least -20 dBv [-18 dBu] is present) = Normal range 0 = off (input level is too low) 1 = on (input is in the right range) = Peak level 0 = off (audio input is set up correctly) 1 = on (the level or gain is too high, audio clips/distorts. Output equipment could be damaged. Adjust the input level so that only the Normal LED is blinking.
X2# = Video type (inputs 3 and 4 only) 1 = Composite video (default) 2 = RGB X2$ = Video signal status 0 = Video signal not detected 1 = Video signal present X2% = 0 to 15, mic talk-over threshold level range, default 6 X2^ = 0 to 30, program ducking level in talk over mode, default = 15 X2& = Lineout status 1 = variable 2 = fixed 3 = independent separate mono Left channel fixed and mono Right channel variable X2( = 0-8, paging delay in 1 second steps, (default = 0, disabled) 0 = 0 second (disabled),
