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.

source as shown in the figure above. When all other cables have been connected, plug the captive screw connector into the
2-pole female connector to connect the switcher to the 12 VDC

N Use only the supplied 12 V power supply for this switcher.
b RGBvideoandaudioinputs(“RGB”)— Each RGB input requires the use of two twisted pair (TP) cables, A and B. Using TP
cables, connect up to four high resolution computer video and audio sources via the PVT RGB D input wallplates to these eight
RJ-45 female connectors.

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.
