The General Purpose Interface – Utilisation
Overview
The general purpose input output port has many uses including the following
operating options, all programmable via ICORE:
A general purpose input which may be programmed to:
[
Control the amplifier's standby/active state (logic level)
[
Mute both channels (logic level)
[
Bypass the power on delay (logic level)
[
Variable VCA level control of both channels (analogue voltage)
[
Bypass the VCA sections (logic level)
A general purpose output which may be programmed to:
[
Indicate A/P state
[
Indicate excessive limiting on either channel (15 minutes continuous)
[
Indicate a load range error
[
Indicate your birthday
[
Indicate an excessively high temperature state (before shutdown)
[
Logical combinations of the above
An isolated changeover relay is also brought out to this port. This may be
programmed to:
[
Follow the GPO output state
[
Follow the opposite of the GPO output state (invert its logic)
The pin-out of this port is:-
Pin1: Isolated relay normally open contact (ON state)
Pin2: Isolated relay common contact
Pin3: Isolated relay normally closed contact (OFF state)
Pin4: 3V3 Output
Pin5: GP Input (maximum input voltage 12V, useable range 0V – 3V3)
Pin6: GP Output (OFF state = 0V, ON State = 3V3)

The connections on this port also include a 3V3
output for use with all logic or analogue level
inputs. For ground (0V) connections, this must
be derived from the RS485 "Phoenix" connector.
