Control Port Digital Outputs
There are many possible uses for the Control Port outputs. For
example, they can be used to turn on auxiliary cooling fans. To do
this the output signal might be used to close a relay. The relay
would then turn the fans on or off.
A Sample Control Port Output Circuit
By monitoring the operating condition of amplifiers (with the IQ
System software), the need for additional cooling would be
apparent. The software could then be used to turn on the
appropriate Control Port input.
Another use for the Control Port outputs might be to light an LED
on an annunciator panel to indicate Preset status, input channel
mute, or any other on/off type function.
