Introduction  
Digital time base correction — Time base correction stabilizes  
the video signal in the time domain. This results in a  
significantly more stable image on the screen and better  
recording quality from input sources with unstable video  
signals, such as consumer VCRs and worn or multi-  
generation VHS tapes.  
About this Manual  
This manual contains information about the Extron YCS SW2  
Switcher, and discusses how to install, configure, and operate it.  
The terms “YCS SW2,” “YCS,” and “Switcher” are used  
interchangeably throughout this manual.  
Simultaneous composite video and S-video outputs — One  
composite video and two S-video outputs allow for  
recording and display at the same time.  
About the YCS SW2  
The Extron YCS SW2 is a high-performance, two input  
(one composite video and one S-video) switcher with three  
simultaneous outputs (one composite video and two S-video),  
digital transcoding and autoswitching capabilities, and digital  
time base correction (TBC). Using a 3-line NTSC/5-line PAL  
digital comb filter, the YCS accepts NTSC 3.58, NTSC 4.43, PAL,  
or SECAM composite video, and decodes the signal into Y  
(luma) and C (chroma) for S-video. As an encoder, it combines  
Y and C signals and outputs a composite video image.  
Individually buffered S-video outputs — Two individually  
buffered S-video outputs are provided on one female  
4-pin mini DIN connector and a pair of female BNC  
connectors, for easy integration.  
Contact closure remote control — Inputs can be selected  
remotely using a user-supplied two-button contact closure  
device.  
Quad standard compatibility — The digital quad standard  
Certain projectors have both video and S-video inputs, but  
can use only one of them at a time. The YCS SW2 solves this  
problem by autoswitching between composite video and  
S-video, then decoding the S-video to feed to the projector. (See  
figure 1-1 under Application Diagrams, later in this chapter.)  
decoder/encoder provides for universal compatibility.  
Enclosure — The YCS SW2 has a compact 1U high, ¼-rack  
wide, 3 inches deep Versatools® metal enclosure that can  
be easily placed or mounted in a variety of locations.  
The YCS SW2 can also be used at the output of a multi-format  
switcher, such as the Extron MPS 112, to automatically select  
between the video and S-video group outputs, sending a single  
S-video signal to the projector. (See figure 1-2.)  
Power supply — An external 12 VDC power supply with a  
two-pin captive screw connector accepts 100 to 240 VAC.  
Rack and furniture mounting — The YCS SW2 can be mounted  
on a rack shelf, under a desk or podium, or on a projector  
pole, with an optional mounting kit.  
Inputs can be selected by pressing the front panel buttons, by  
enabling autoswitching using a jumper wire, or by contact  
closure using a remote push-button device.  
Features  
Autoswitching — The YCS SW2 can be configured to  
automatically switch to the active input when the  
YCS detects a video signal, thus providing hands-free  
switching. If both the composite video and the S-video  
signals are present, the switcher defaults to input 2,  
S-video.  
Digital encoding and decoding — The YCS SW2 digitally  
decodes (separates) the composite video input signal into  
Y and C for S-video, and encodes (combines) the Y and C  
signals of S-video input into composite video.

Insert the two legs of the provided square U-bolt through  
the slotted holes on the back side of the bracket mount  
plate, place the two legs around the ceiling pole, then  
insert them through the round holes on the backing brace.  
The PMK 250 Low Profile Projector Mount Kit is an above-  
projector mounting kit that attaches to a 1” to 2” diameter  
projector mounting pole. It can hold more than one device,  
in a variety of sizes. The PMK 250 is available in black (part  
#70-526-02) or white (part #70-526-03).  
For a typical (1.5” to 2.0” diameter) pole You can  
use the supplied square U-bolt, which fits a typical  
ceiling pole.  
Follow these steps to mount the YCS SW2 on the PMK 250  
bracket as follows:  
For a smaller pole — Locally obtain a square U-bolt  
that fits your ceiling pole. The slotted holes on the  
bracket can accomodate a square U-bolt for pole sizes  
from 1.0” to 2.0” in diameter.  
1.  
Remove the front panel from the PMK 250, using an Extron  
Tweeker or other small Philips screwdriver. (Retain the  
four screws to reattach the plate when finished.)  
2.  
Remove the protective backing from the self-adhesive  
rubber pad, and place the pad on the PMK 250 mount  
plate, centering it between the two holes (see figure 2-8).  
8.  
9.  
Move the PMK 250 up to the desired location on the ceiling  
pole, as close to the ceiling as desired.  
Secure the back brace to the square U-bolt using the  
included hex nuts, washers, and lock washers. Tighten the  
hex nuts securely.  
3.  
4.  
Remove any rubber feet from the bottom of the YCS SW2.  
Secure the YCS to one side of the mounting bracket,  
using two of the supplied 4-40 x 3/16 screws in opposite  
(diagonal) corners.  
Be sure to tighten the hex nuts securely enough that the  
PMK 250 does not slide down the ceiling pole. A socket  
wrench is recommended to tighten the hex nuts.  
5.  
6.

Contact closure, later in this chapter.)  
Figure 2-11 — Power connector wiring  
CAUTION  
Do not tin the stripped power supply leads before  
attaching the captive screw plug to them. Tinned  
wires are not as secure in the captive screw  
connectors and can be easily pulled out. They may  
also break after being bent several times.  
Jumper-wire together the two ports labeled “Auto-SW”  
(pins 4 and 5) to enable autoswitching. (See Autoswitching,  
later in this chapter.)  
The two power cord wires must be kept separate  
while the power supply is plugged in. Remove  
power before wiring.  
Wiring the Power Connector  
To wire the connector for the external power supply,  
1.  
2.  
Cut the DC output cord to the length needed.  
Strip the jacket to expose 0.2 inches (5 mm) of the  
conductors.  
Wiring the Captive Screw Connector  
The 5-pin, 3.5 mm captive screw connector is used for optional  
push-button remote control of the YCS SW2, and/or to enable  
autoswitching between inputs connected to the YCS. The  
following figure shows the pin assignments for the captive  
screw connector.  
CAUTION  
Exposing more than 0.2” (5 mm) of the copper  
wires could allow the stripped wires to touch each  
other, causing a short circuit. This could result in  
the external DC power supply overheating and/or  
burning.  
AUTO-SW  
CONTACT  
Stripping the wires to expose less than the  
recommended amount may cause them to slide out  
of the connector too easily, even if they are tightly  
pinched by the captive screws.

You can set up the YCS to automatically select the active,  
connected input. If both inputs are active, selection defaults to  
input 2 (S-video). You enable autoswitching by connecting pins  
4 and 5 of the rear panel captive screw connector with a small  
piece of wire that functions as a jumper. Autoswitching remains  
in effect as long as the jumper wire is connecting these two pins  
together.

Selecting an Input by Using the Buttons  
YCS SW2  
The YCS SW2 has two inputs available — one composite  
video and one S-video. You can select either of these inputs by  
pressing the appropriate button on the front panel. When an  
input is selected, its LED lights and remains lit while its input  
source is active.  
The front panel buttons are labeled “1” and “2” for the two  
inputs. Press input button 1 to select the composite video input,  
or button 2 to select the S-video input.  
You can also set up the YCS to select inputs via contact closure  
or autoswitching. For information on enabling input selection  
by either of these methods, see Contact closure or Autoswitching,  
earlier in this chapter.  
The YCS SW2 does not have non-volatile memory.  
Therefore, the input selection defaults to input 1 after a  
power loss.
