GPoutputs
Relays are used for GP outputs. All 3
relay contacts are made available on the
GP output connector to provide flexibility
in use—they can be wired to produce
a standard closure when activated, to
produce a default closure that becomes
open when active, or to pass a ground
or voltage that is made or broken when
activated. Having all 3 contacts also
allows audio or other signals to be fed
through the relay and switched by GPIO
control if required. The Common pin is
always connected to one of the other
two pins by the relay—when the relay is
NOT activated, Common is connected to
the Normally Made pin. When the relay
becomes active (the assigned GP function
is triggered), the Common pin becomes
connected to the Normally Open pin. To
create a dry closure, Some typical wiring
examples are shown on this page.

GPinputs
Opto-isolated inputs allow for mixing
console functions to be triggered remotely
by other equipment. Applying voltage
across the + and - pins of an opto will
trigger it. If using a dry (no voltage) closure
as a trigger, one side of the closure should
be wired to one of the opto’s pins, the
other side of the closure should be wired
to ground, and the other side of the opto
should be wired to +ve voltage. Both
voltage and ground should be sourced
from the GPIO card itself where possible.
If the 3rd party kit sends a single logic
line, as opposed to a closure pair, both
pieces of equipment will need to share the
same ground reference, or +ve voltage
will need to be supplied by the 3rd party
kit. Common wiring examples are shown
on this page.
GP INPUT WIRING EXAMPLE #1
• In this example, the 3rd party
equipment provides a dry
closure. Voltage and ground are
supplied by the GPIO card
• In this example, the 3rd party
equipment provides a single
tally line which is grounded on
activation. Voltage is supplied
by the 3rd party. If voltage
is instead supplied by the
GPIO card, the two pieces of
equipment MUST have the
same ground reference.
• Wiring shown provides a dry-
closure on activation
• Wiring shown provides a
ground on activation. Note,
the ground is provided by the
device being triggered.
