PoleVault™ Switcher
The Extron PVS 204SA is a four input, two output, twisted pair,
audio and video switcher with a built in audio amplifier. The PVS 204SA accepts high resolution (RGB) video and audio, and
composite video and audio signal inputs, along with a line level mono audio auxiliary/mix input. The PVS 204SA is part of
the PoleVault System, and is used in conjunction with the Extron PVT series of transmitters and with Extron speakers.
Installing the PVS 204SA Plus
Mount the PVS 204SA Plus in the Extron PMK 450 (Projector Mount Kit), which is installed above the projector, as follows:
1. Follow steps 1 through 3 of “Installation — Stage Four”, in the PoleVault System Installation Manual, supplied with the complete
PoleVault System.
2. Lift the PMK’s bottom plate (with the PVS 204SA Plus and power supply installed) up to the base of the pole, and connect the cables
to the switcher as shown below.

The PoleVault™ signal transmission method is specific for PVS 204SA Plus switchers working with PVT wallplates.
DO NOT connect to an MTP system. DO NOT connect to an Ethernet/LAN or data transmission system.
Do not connect an RGB cable (cable A) to the top ports (3A and 4A) when connecting composite video cables to the lower ports
(3B and 4B).
The PVS 204SA Plus is capable of receiving signals from PVT wallplates located up to 100 feet (30 m) away. The optimum
distance is between 50 and 75 feet (15 and 22 m).
Cable A carries the video signals and cable B carries the audio signal, vertical sync information and 5 VDC current from the PVS
to power the PVT wallplates.
The ports on the rear of the PVS 204SA Plus are color coded for input number and signal type. To ensure correct cable
identification and connection during installation, a sheet of color coded cable labels is supplied. Refer to “Labeling the A/V Inputs”
section in the Polevault System Installation Manual, for details.
When connecting the TP cables to the PVS 204SA Plus, do not cross-connect the cables; connect input 1’s cable A to the RJ-45
port labeled 1A, and input 1’s cable B to the RJ-45 port labeled 1B. Likewise, connect input 2, 3, or 4‘s cable A to its corresponding
numbered A port, and cable B to its B port.
RJ-45 termination must comply with the TIA/EIA T 568A or 568B wiring standards for all connectors. The same standard
MUST be used at both ends of all cables. Refer to the PoleVault System Installation Manual for details.
The cables supplied with the PoleVault system are terminated to the TIA 568A standard.
RGBvideooutput — Connect a VGA cable to this female 15-pin HD connector and to the projector for RGB video.
PRELIMINARYPRELIMINARY
Composite(video)output — Connect a cable with an RCA connector to this female RCA jack and to the projector for
e
composite video.
Control connection
fRS-232/MLC/IRcontrolport — 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 the MLC MediaLink
Controller or an optional IR Link IR signal repeater.
The protocol is 9600 baud, 8-bit, 1 stop bit, no parity, and no flow control.
• The MLC provides remote control of input switching and volume.
• The IR Link accepts modulated IR signals from a remote control (e.g., the Extron IR 452 remote) enabling the remote
control to be used for selecting the switcher inputs.
N The PVS 204SA Plus power supply can support a typical system: for example, a PVS 204SA Plus, 4 PVT Wallplates,
2 or 4 speakers, and an MLC 104 IP Plus with an IRCM DV+.
• If an SCP 104 is used in the system, the MLC 104 Plus MUST have its own power supply.
• The PVS 204SA Plus provides sufficient power to run an MLC 104 IP Plus or any MLC 52 RS model.

Enable the switcher’s paging sensor port, using Global Configurator or the MediaLink Switchers (MLS) and PoleVault
Switchers (PVS) control software, available at www.extron.com
The Priority Page Sensor Kit (part #70-619-01) is an optional accessory which must be purchased separately.
hAux/Mixaudioinput — To mix an auxiliary, mono, line-level audio signal (from a wireless microphone receiver, for
example) with the selected input’s audio, connect the cable from the mono source to this 3-pole captive screw connector.
The signal can be balanced or unbalanced. Wire the supplied blue 3-pole male captive screw connector as shown.
Audio input signal is present regardless of the selected input on the switcher. The audio level is not affected by the program volume.
For wired microphones, connect an MP 101 microphone-to-line preamplifier to the Aux/Mix port on the
PVS 204SA Plus, to convert the microphone output to line level. Follow the installation instructions in the user’s manual
supplied with the MP 101 to connect the microphone. See below to wire the MP to the switcher.
iLineoutaudioport— This port is used for recording or assisted listening devices. It can be configured via RS-232 for fixed
or variable audio output (default is variable). It can be wired for balanced or unbalanced, mono or stereo signal outputs.
jDCVolumecontrolport(Vol/Mute) — This port is used to connect an Extron external volume control module, such as a
VCM, to the PVS 204SA Plus. The range is 0 to 10 V, where 0 V is mute and 10 V is maximum volume. When connected,
the external volume control module is the sole volume controller. Connect the supplied blue, male, 3-pole captive screw
connector to this port.
N
Do not control the PVS volume via RS-232 if this port is connected to a VCM 100, or a VC 50. If a VCM is controlling the
volume, an MLC should not control audio volume via RS-232.
kAmpliedOut — Wire and connect the supplied black 4-pin 5 mm connector to this port, marked “L” and “R” (left and
right) for 4 or 8 ohm speaker output.

Configuring the PVS 204SA Plus Switcher
The PVS 204SA Plus 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
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, the Global Configurator
(GC2) program for Windows, or the MediaLink Switchers (MLS) and PoleVault Switchers (PVS) control software, available
at www.extron.com.
RS-232portprotocol: 9600 baud, 8 bit, 1 stop bit, no parity, no flow control.
N
N Firmware updates can be made only via the front panel Config port.
Seepage4fortheSISCommand/responseTableforthePVS204SAPlus.
The speaker setup covers two individual speakers of 8 ohm impedance or two pairs of speakers in parallel, where each channel drives
a maximum output load of 4 ohms.
Configuration can also be completed by connecting a 2.5 mm stereo mini
cable (part # 70-335-01, see pinout table at right) to the 2.5 mm port on the
front panel. This port has the same protocol as the RS-232 port on the rear
panel.
Do not tie both L and R outputs to each other and/or to ground or it may short the outputs and damage the amplifier.
