This guide provides basic instructions for
an experienced installer to set up and
operate the Extron MSW 4V SDI rs.

Installation

Step 1

Turn all of the equipment off and
disconnect it from the power source.

Step 2

A mounting example is shown in
figure 1. Select your mounting
option, install the appropriate
brackets, and mount the MSW.
Otherwise, install the four rubber
feet (included) and place the mini
SDI switcher on a desktop. See
“Installation” in the MSW 4V
SDI rs User’s manual for more
mounting options.

Step 3

Connect the video input cable(s)
using SDI video inputs 1 through 4
(a). Refer to figure 2 or see “Rear
Panel Connections” in the user’s
manual for more information.

Figure 1 – Rack shelf mount

Step 4

Attach the video output cable(s).
Connect up to two SDI output
devices to the MSW (b).

N

Step 5

If the MSW is to be used as a remote control for a computer or host controller, connect a
9-pin HD connector to a computer, then connect a 5-pole captive screw connector to the
RS-232 port (c) on the mini SDI switcher. Protocol for this port is 9600 baud, 8 data bits,
1 stop bit, no parity. Wire the connector as follows: Pin 2 = Tx, Pin 3 = Rx, Pin 5 = Gnd.
Refer to figure 3 or see “Serial Communication” in the user’s manual for more information.

Outputs A and B output

an identical signal.

Step 6

Power up the input and output devices.
Distribute power to the MSW by
assembling the external power supply
cable (see figure 4) and connecting it to
the power port. Once plugged in, the
mini SDI switcher automatically turns on.
See “Rear Panel Connections” in the
user’s manual for more information.

Operation — Connecting an input to the output

Step 1

Determine the necessary operation
mode for the MSW (the default is
normal). Choose Autoswitch (press

and

c

automatically switch to the highest
numbered input with active sync pulses.
Choose Normal (press d and
simultaneously) to manually change the
input. Refer to figure 5 or see “Mode

modes.

Step 2

• If using normal mode, choose the desired input by pressing and releasing its input
button (b). The LED (a) for the selected input lights.
