Setup Guide — SW AV Series Switchers
This card provides quick start instructions for an experienced
installer to set up and operate Extron ® SW AV Series
S-video, composite video, and audio switchers.
Installation
Step 1 — Mounting
Turn off or disconnect all equipment power sources
and mount the switcher as required.
Step 2 — Video and audio inputs
• S-video models — Connect up to 4, 6, 8, or 12 video inputs to the Input
4-pin mini DIN connectors of the switcher.
• Composite video models — Connect up to 4, 6, 8, or 12 video input cables
to the Input BNC connectors of the switcher.
• Captive screw connector audio models — Connect up to 4, 6, 8, or 12 balanced or
unbalanced stereo audio or mono audio devices to the Input 5-pole captive screw
connectors of the switcher.
• RCA connector audio models — Connect up to 4, 6, 8, or 12 balanced or unbalanced
stereo or mono audio devices to the RCA connectors of the switcher.
Step 3 — Video and audio outputs
• S-video models — Connect a composite video display to the Output A
or
BNC connector.
Connect an S-video display to the 4-pin mini DIN Output B connector.
• Composite video models — Connect composite video displays to the
Output A and Output B BNC connectors.
• Captive screw connector audio models — Connect balanced or unbalanced
stereo audio or mono audio devices to the Output A and Output B 5-pole
captive screw connectors. Wire the connectors as shown below:
• RCA connector audio models —
Connect an unbalanced stereo audio
or mono audio device to the Output A
RCA connectors. Connect
a balanced or unbalanced
stereo audio or mono audio
device to the Output B 5-pole
captive screw connector.
Step 4 — Remote connector (optional)
SW 4 and SW 6 models only — Connect an RS-232 or IR device OR
a contact closure device, such as a KP 6 Keypad Remote Control.
N For RS-232 control and IR control, use a cable with
ONLY pins 2, 3, and 5 connected.
For contact closure control, use a cable with pins 2
and 3 NOT connected.
RS-232 communications protocols:
• 9600 baud
• 8 data bits
• 1 stop bit, no parity • no flow control
For contact closure control, short the pin for the desired input
to pin 5 to select that device. To force an input to be always selected, leave the short in place.
N For contact closure control, auto switch mode must be off. See “Switch mode (video switchers)“
on the back page. Contact closure control overrides front panel input selections.
