Extron Electronics MSW 4V SDI rs Setup Guide - Manual

Setup Guide — MSW 4V SDI rs
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.
Step 4
Attach the video output cable(s).
Connect up to two SDI output
devices to the MSW ( b ).
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 (
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.
(2) 4-40 x 3/16" Screws
Use 2 mounting holes on
opposite corners.
