Mono Audio (local audio) output — Connect an audio

 

device, such as an audio amplifier or powered speakers to

 

this 3.5 mm, 5-pole captive screw connector. This connector

 

outputs the selected unamplified, mono line level audio. See

 

figure 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 (figure 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.

NThe switcher can be controlled only by an RS-232 device OR a contact closure device, not both.

NThe 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.
