f Mono Audio (local audio) output — Connect an audio
device, such as an audio amplier or powered speakers to
this 3.5 mm, 5-pole captive screw connector. This connector
outputs the selected unamplied, mono line level audio. See
gure 2-6 to properly wire the output connector. Use the
supplied tie-wrap to strap the audio cable to the extended
tail of the connector.

C Connect the sleeve to ground (Gnd). Connecting
the sleeve to a negative (-) terminal will damage the
audio output circuits.
C The length of the exposed (stripped) portion of
the copper wires is important. The ideal length
is 3/16” (5 mm). Longer bare wires can short
together. Shorter bare wires are not as secure in the
direct insertion connectors and could be pulled out.
The volume level for the local output can be individually set
under serial port control. See chapter 3, “Remote Control”,
for details.
By default, the audio ties follow the video ties. Audio
breakaway switching, which can be performed under serial
port control, allows you to select from any one of the audio
input sources and route it separately from its corresponding
video source. See chapter 3, “Remote Control”, for details.
g Remote RS-232/contact closure connector — Connect a
computer or control system to this 9-pin D connector (gure 2-7)
to allow remote control using the Simple Instruction Set (SIS™),
the Extron graphical control program for Windows, or a contact
closure device. See chapter 3, "Remote Control", for details.
You can also connect a KP 6 remote control keypad
(part #60-111-20) or an IR 102 Kit infrared remote control
(part #70-224-01) system to this connector.

N The switcher can be controlled only by an RS-232 device
OR a contact closure device, not both.
N The cable used to connect the Remote port to a computer,
control, contact closure device, or IR control kit may
need to be modified by removing pins or cutting wires.
If unneeded pins are connected, the switcher may hang
up. See chapter 3, "Remote Control", for additional
information.
