GPIO Select
– This drop down list selects the GPIO port to view and change
se�ngs.
Type
– This op�on selects whether the selected GPIO port is an input, an
output or whether it is disabled. Ports configured as inputs are ac�ve low
and they have a weak internal pullup. Ports configured as outputs are open
collector driven and are therefore ac�ve low.
Input Function
– This op�on selects the required func�on that the selected
GPIO input controls. GPIO inputs can be set to control a local func�on and a
virtual GPIO output if required. If no local func�on control is needed, but
control of a virtual GPIO output is required, select Virtual GPO Only. The
assignment for which GPIO input triggers a virtual GPIO output is made on
the virtual GPIO se�ngs page. This op�on is only available when the type is
set to input.
Input Action
– This op�on selects the opera�onal mode of the selected
GPIO input. In momentary mode, the selected func�on is ac�ve whilst the
input is asserted low. In latching mode, a separate ac�ve low pulse is
required to enable and disable the selected func�on. This op�on is only
available when the type is set to input.
Output Trigger
– This op�on selects the func�on that triggers the GPIO
output. GPIO outputs can be triggered by a local func�on, a virtual GPIO
input and an Ember+ consumer if required. If a local func�on trigger is not
needed, but a virtual GPIO input or Ember+ consumer trigger is required,
select Virtual GPI Only or Ember+ Consumer Only. The assignment for which
virtual GPIO input triggers a GPIO output is made on the virtual GPIO
se�ngs page. This op�on is only available when the type is set to output.
GPIO Button Mode
– Selects the opera�onal mode of the GPIO bu�on. In
momentary mode, the GPIO outputs controlled by the bu�on are ac�ve
whilst the bu�on is pressed. In latching mode, a separate bu�on press is
required to enable and disable the GPIO outputs. In auto mode, the bu�on
has a momentary ac�on that will automa�cally latch on or off if pressed
briefly.
Relay Trigger
– The output relay, which provides both normally open and
normally closed contacts on the GPIO connector on the rear panel, can be
triggered by mul�ple func�ons, inputs and states. When any of the selected
triggers become ac�ve, the relay is switched on. To select mul�ple triggers,
click on the required op�ons whilst holding down the Ctrl key on the
keyboard. The CLEAR ALL bu�on provides an easy way to remove all current
relay trigger assignments.
