2.3.2.3. General Purpose Outputs (GPO).
The physical connectors used are DB15-female, with the following pinout:
Pinout of DB15 GPO 1 - 8 connector
- Pin 1: GPO 1
- Pin 9: GND_GPO 1-4
- Pin 2: GPO 2
- Pin 10: GND_GPO 1-4
- Pin 3: GPO 3
- Pin 11: GND_GPO 1-4
- Pin 4: GPO 4
- Pin 12: +5V GPIO
- Pin 5: GPO 5
- Pin 13: GND_GPO 5-8
- Pin 6: GPO 6
- Pin 14: GND_GPO 5-8
- Pin 7: GPO 7
- Pin 15: GND_GPO 5-8
- Pin 8: GPO 8
Remarks: please note that a common ground (GND) is provided for inputs 1 to 4 and another
one exists for inputs 5 to 8. Pin 12 supplies a +5V reference voltage to ease wiring.
Pinout of DB15 GPO 9 - 16 connector
- Pin 1: GPO 9
- Pin 9: GND_GPO 9-12
- Pin 2: GPO 10
- Pin 10: GND_GPO 9-12
- Pin 3: GPO 11
- Pin 11: GND_GPO 9-12
- Pin 4: GPO 12
- Pin 12: +5V GPIO
- Pin 5: GPO 13
- Pin 13: GND_GPO 13-16
- Pin 6: GPO 14
- Pin 14: GND_GPO 13-16
- Pin 7: GPO 15
- Pin 15: GND_GPO 13-16
- Pin 8: GPO 16
Remarks: please note that a common ground (GND) is provided for inputs 9 to 12 and another
one exists for inputs 13 to 16. Pin 12 supplies a +5V reference voltage to ease wiring.
2.3.2.4. Cooling fan.
The cooling fan doesn't need to operate in enviroments with "normal" termperature. The unit is
cooled by natural convection, hence totally silent. When, for whatever reason, high operating
temperature is reached, the low acoustic noise fan starts.
2.3.2.5. Power supply.
The mains power supplies connnectors (main and backup) are located in the back left area of
the unit. Both internal power supplies are auto ranging, accepting: 90 - 132 V AC & 187 - 264 V
AC, 47-63Hz.
2.3.2.6. Remarks on NETBOX DSP GPIOs wiring.
AEQ simplifies installation by providing the connection between the system and
the connected devices. The "CP CAB GPIO" accessory is provided on-demand.
It consists on a DB15 male connector soldered to a 15-way 6-meter long cable,
with no connectors in the other end, for GPIs and GPOs. Each cable allows for
the connection of the 8 GPIs or GPOs provided in each device’s connector.
