CHAPTER 3 | INSTALLATION AND OPERATION
Pin 10 - Status GND
Pin 10 on the 10-pin I/O port provides a ground reference for the Output pins
(7-9), and is required for any device that needs to sense the potential.
Pin 10 connects to the GND pin of an I/O port on an external controller.
On/Off Control (12V Trigger, 3-5V Trigger and Signal Sense)
The CP-16i can be powered on and off externally by using the two signals
12V trigger and 3-5V trigger. A Signal Sense function is also provided which
automatically can switch on the CP-16i in the event of an audio signal and
switch off the CP-16i to enter standby mode when no audio signal has been
present on the signal terminals for approximately 13 minutes. The Signal Sense
function consists of an audio detection circuit and a timer. If an audio signal of
more than typically 1.3mVrms is present on the Signal Sense terminals, the
CP-16i will always be in the On mode. If none of the two triggers are high and
audio is not present at the terminals the timer will switch off the CP-16i after 13
minutes.
NOTE:
Pins 1 and 2 on the 10-pin I/O port provide Signal Sense (+ and -)
inputs.
NOTE:
When changing control signals from on mode to standby mode, there
is a 200ms delay before the main SMPS turns off. This is to provide time for
internal circuitry to power down in order to meet the standby mode current
draw requirements.
Enabling and Disabling Zones
The 8-position dip switch labeled “ZONES” provides the ability to individually
enable or disable any of the 8 Zones. It is recommended to disable Zones that
are not being used, to lower power consumption.
To disable a Zone, flip the associated switch (1-8) from Enable (default setting)
to Disable.
ZONES Dip Switch
The UP position enables each Zone; the Down position enables each Zone.
