Setup Guide
—
MSW 4V rs & 4SV rs
This guide provides basic instructions for
an experienced installer to set up and
operate the Extron MSW 4V rs & 4SV rs.
Installation
Step 1
Turn all of the equipment off and
disconnect it from the power source.
Step 2
Select your mounting option, install
the appropriate brackets, and mount
the MSW. Otherwise, install the four
rubber feet (included) and place the
mini video switcher on a desktop. A
mounting example is shown in figure 1.
See “Installation” in the MSW 4V rs and
MSW 4SV rs Series User’s manual
for more mounting options.
Step 3
Connect the video input cable(s). Using
video inputs 1 through 4, connect video
inputs to the MSW using the connectors
(4-pin mini DIN [
e
] or BNC [
f
])
and signal type (composite or S-video)
appropriate for your model.
Step 4
Attach the video output cable(s).
Connect up to two video output devices
to the MSW using the connectors (4-pin
mini DIN [
d
] or BNC [
a
]) and signal
type (composite or S-video) appropriate
for your model. Refer to figure 2 or see
“Rear Panel Connections” in the user’s
manual for more information.
N Outputs A and B output an
identical signal.
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 (
b
) on
the mini 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.
(2) 4-40 x 3/16" Screws
Use 2 mounting holes on
opposite corners.
