Installation

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

2. If feet were previously installed on the bottom of the MSW, remove

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.

Installation

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.

Rear Panel Connections

SDI Inputs (1 through 4) connectors — Connect SDI video inputs

to these BNC connectors.

SDI Outputs (A and B) connectors — Connect one or two SDI

devices to these BNC connectors. The MSW outputs re-clocked

SDI outputs.

Contact connector — Connect a remote contact closure device to

the switcher for remote control of the switcher, or daisy chain the

switcher to other MSWs for remote control of the other switchers,

via this 5-pin captive screw connector

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.

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.

Connections

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.
