PVS 240SA 1 Chapter One Introduction About this Manual About the PVS 240SA Application Diagrams
Introduction About this Manual This manual covers the installation, operation, and configuration of the Extron PVS 204SA PoleVault™ Switcher. Throughout the manual, this switcher is interchangeably referred to as the PVS 204SA, PVS switcher, PoleVault switcher, PVS, and switcher. About the PVS 204SA The Extron PVS 204SA is a four input, two output, twisted pair, audio and video switcher with a built in audio amplifier.
Features Twisted pair inputs — The switcher accepts two independent, high resolution RGB video and audio signals and two composite video and audio signals, transmitted on twisted pair cable from a source up to 100' (30 m) away. Video output — The PVS switcher can switch between four inputs (two RGB and two composite). Aux/Mix input — The PVS switcher can mix a mono line level audio input with the audio input from the video/audio source.

Installation UL/Safety Guidelines The Underwriters Laboratories (UL) guidelines 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 204SA can be mounted on the Extron PMK 450 (Pole Mount Kit), which should be installed above the projector. The low profile of the PVS switcher and the PMK 450 allows them to be installed in tight spaces. To install the PVS 204SA on the PMK, follow the steps shown in the instruction guide supplied with the PMK 450. If the PMK 450 is already installed, do the following: 1.

N The composite video cables supplied with the PoleVault system are terminated to the TIA 568A standard, as shown in figure 2-6.
ã Stereo and Dual Mono selection — To select stereo or dual mono audio output, set the switch to the desired position. Dual mono sums left and right audio signals together and outputs the same signals on both audio output channels. Default setting is mono. N For best results when speech is the primary audio, set this switch for dual mono with the high pass filter set to on. If music is involved, set the switch to stereo with the high pass filter set to off.
Installation, cont’d Control connection h RS-232/MLC/IR control port — The PVS switcher can be controlled via an RS‑232 connection directly from a host computer, a control system, or a MediaLink Controller (MLC). For IR remote control, connect an Extron IR Link to this port. RS-232 connection can be used to configure the PVS switcher. Connect a cable between this port and an optional Extron MLC MediaLink Controller or an optional IR Link IR signal repeater.

C AMPLIFIED OUTPUTS 4/8 Ohms L R Do not tie both L and R outputs to each other and/or to ground. Doing so will short out the outputs and damage the amplifier.
Installation, cont’d Connecting speakers to the PVS 204SA To obtain the correct impedance loading for your specific speaker system, follow the relevant setup as shown below.
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 204SA 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 transmitters to the switcher.
Installation, cont’d Labeling the PVT Decora face plates To help identify the input number and type of signal that RGB IN #1 any PVT Decora transmitter sends to the PVS switcher when the transmitter is installed, a series of small labels are supplied. A label identifying the transmitted signal type should be affixed to each Decora faceplate (top or bottom) where it can easily be seen after installation.

Auto switching indicator LED — When lit, this green LED indicates that the auto switching is turned on.
Min/Max LED — This red LED indicates when the range limits for the power amplifier level, Aux/Mix volume, or input gain level have been reached. See “Setting Up and Optimizing the Audio”, later in this chapter, for details. It lights as follows: • When setting up input levels • When the PVS reaches the min./max. amplifier level • When the PVS reaches the min./max. Aux/Mix level g Aux/Mix level encoder — This recessed rotary encoder allows front panel adjustments specific to the Aux/Mix input level.
Operation and Setup, cont’d Setting the separate switcher mode via the front panel 1. Press and hold input selection buttons 1 and 3 simultaneously for 4 seconds (see figure 3-4). All the input selection LEDs blink once. 2. Release the buttons. The switcher has enabled separate switcher mode and two LEDs remain lit (one for RGB format, one for composite video format).

Setting Up and Optimizing the Audio The following steps ensure optimal sound is achieved by configuring the PVS 204SA properly. For each step, refer to the sections indicated for more information. Steps for optimizing the audio 1. Ensure all the settings are at default. These are the settings the PVS has upon initial power up. The default settings are as shown below. • Volume is set at 50%. • Bass and treble are set at 0. • Power Amplifier level is set to 50% (default level is 0 dB).
Operation and Setup, cont’d Gain control Individual channel input sensitivity control Individual channel input gain control adjustments are made by rotating the encoder while pressing in the selected input button. The adjustment range is -18 dB to +24 dB, with the default set at 0 dB. N Adjusting input sensitivity for all inputs ensures that all inputs are at the same level, and at the highest level possible before clipping occurs.
Clipping indicator The clipping LED is a real time indicator of when the amplifier is clipping. It flashes red when clipping is taking place (see figure 3-7). AUDIO AUX/MIX MIN/MAX LEVEL CLIP This LED flashes when the amplifier output is clipping. Figure 3-7 — Front Panel audio clipping indicator LED and recessed encoders N To reduce the risk of damage to the speaker, reduce the amplifier level by turning the encoder counterclockwise until the Clip LED turns off.
Operation and Setup, cont’d Front Panel Security Lockout (Executive Mode) 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, and a red lockout LED (next to the power LED) lights to indicate that executive mode is on.
PVS 204SA 4 Chapter Four Serial Communication RS-232 Programmer’s Guide Updating Firmware
Serial Communication The PVS 204SA 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 RS-232/MLC/IR port. Alternatively, the switcher can be controlled by an optional 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 Extron’s Simple Instruction Set (SIS™) commands or the Global Configurator RS-232/MLC/IR (GC2) 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.
