Introduction
The Extron MSW 4V SDI is a four-input, two-parallel-output, mini SDI
(serial digital interface) switcher (MSW). The MSW is a member of the
Extron VersaTools™ line of basic distribution amplifiers, switchers, and
associated video accessories.
The MSW switches among up to four SMPTE-259M serial video SDI
inputs on female BNC connectors and outputs two identical equalized
and re-clocked SDI outputs on female BNC connectors. The MSW 4V
SDI automatically recognizes 4fsc PAL, 4fsc NTSC, component 4:2:2, and
Widescreen 4:2:2 standards.
The switcher can be operated from the front panel or via a contact
closure device connected to the rear panel such as an Extron KP 6
Keypad Remote Control or an IR 102 infrared remote control kit. The
MSW also features a front panel selectable autoswitching mode that
automatically switches to the highest numbered input with active SDI
signals.
The MSW ships with an external 12VDC power supply.
Installation
The 1U high, quarter rack width, MSW 4V SDI can be mounted on a
rack shelf, mounted under a desk or tabletop, or mounted on a projector
bracket.
Rack mounting
For optional rack mounting, mount the MSW on a VersaTools 19" 1U
Rack Shelf (Extron part #60-190-20) (figure 1) or a standard Universal 1U
Rack Shelf (Extron part #60-190-01) (figure 2). On the standard rack
shelf, the MSW mounts in one of four locations to the rear of the rack or
in one of four locations to the front of the rack.
1. If feet were previously installed on the bottom of the MSW, remove
them.
2. Mount the MSW on the rack shelf, using two 4-40 x 3/16 screws in
opposite (diagonal) corners to secure the MSW to the shelf.
3. Install blank panel(s) or other unit(s) to the rack shelf.
Only products in the VersaTools line can be mounted to a
VersaTools shelf. Most 1U rack-mountable Extron products can
be mounted on the standard shelf.
Furniture or projector mounting
Furniture mount or projector mount the MSW using the optional
mounting kit (Part #70-212-01, furniture, or 70-217-01, projector) as
follows:
1. Attach the mounting brackets to the MSW with the machine
screws provided (figure 3).
(2) 4-40 x 3/16" screws
Use 2 mounting holes on
opposite corners

them.
3.For furniture mounting, hold the MSW with the attached brackets
against the underside of the table or other furniture. Mark the
location of the screw holes of the bracket on the mounting surface.

4.For furniture mounting, drill 3/32” (2 mm) diameter pilot holes,
1/4” (6.3 mm) deep in the mounting surface at the marked screw
locations.
5.For furniture mounting, insert #8 wood screws into the four pilot
holes. Tighten each screw into the mounting surface until just less
than 1/4” of the screw protrudes.
6.For furniture mounting, align the mounting screws with the slots
in the brackets and place the MSW against the surface, with the
screws through the bracket slots.
7.For furniture mounting, slide the switcher slightly forward or
back, then tighten all four screws to secure the MSW in place.

The switcher must be in normal (manual) mode for contact
closure to work.
To select an input using a contact closure device, momentarily
short the pin for the desired input number to logic
ground (pin 5). To force one of the inputs to be
always selected, leave the short in place. The short
overrides any front panel input selections.
You can also daisy chain multiple MSWs via the
Contact connector for front panel control of all switchers; touch
the input button on one MSW to switch all MSWs. Wire pin 1 to
pin 1, pin 2 to pin 2, and so on.
CAUTION
Power supply voltage polarity is extremely important.
Applying power with incorrect voltage polarity could
damage the power supply and the MSW. Identify the power
cord negative lead by the ridges on the side of the cord.
4
Power connector — Plug the external 12V power supply into this
2-pole captive screw connector. The power supply is included
with the unit. Figure 5 shows how to wire the connector.
Do not tin the stripped power supply leads before installing the
captive screw connector. Tinned wires are not as secure in the
captive screw connectors and could be pulled out.
The two power cord wires must be kept separate while the
power supply is plugged in. Remove power before wiring.

To verify the polarity before connection, check the no load power
supply output with a voltmeter.
Alternatively, an Extron P/S 100 Universal 12VDC Power Supply
can power up to ten MSWs or other Extron 12V DC devices using
only one AC power connector.
