Input
• When set to an ‘Input’ an ‘Input Function’ option is available. This allows
a specific function to be assigned to an output, for example, an input can
be set to mute any of the physical audio inputs or outputs. Inputs can
also be used to drive other outputs if this is the only requirement then
the ‘Input Function’ can be set to ‘-’.
• On physical ports the ‘Input Mode’ can also be selected. This can be set
to either ‘Latching’ or ‘Momentary’. When set to ‘Latching’ making the
input active briefly will toggle whether the input and function of that
GPIO is enabled or disabled, whereas ‘Momentary’ keeps the input and
function enabled whilst the input is active. Cough ports don’t have an
‘Input Mode’ option as they rely on the button on the AVN-HA1 or AVN-
HD1 front panel.
• Virtual ports have an extra option ‘vGPIO Source’ this allows them to be
triggered by the vGPO of another unit on the network, when another
unit has a vGPO available the vGPO will be shown in this dropdown
menu, when the vGPO becomes active the assigned input and its
function will be triggered.
Output
When set to ‘Output’ an ‘Output Trigger’ dropdown menu is displayed. A
trigger can be assigned to an output and when the trigger is active, the
output will also be active. the options in the menu are as follows:
• Eth Link Down – Active when no connection is available on the upper
RJ45 network interfacing port.
• AoIP Link Down – Active when no connection is available on the lower
RJ45 network interfacing port.
• AC Power Off – Active when the status of the AC port is in fault condition
(red AC status LED).
• DC Power Off – Active when the status of the DC port is in fault condition
(red DC status LED).
• PTP Sync Lost – Active when the connection to the PTP master is lost.
• GPI n (where n is from 1 to 10) – Active when GPI n is activated.
• Cough n (where n is from 1 to 8) – Active when Cough n is activated.
• vGPI n (where n is from 1 to 10) – Active when vGPI n is activated.
• User Button n (where n is from 1 to 3) – Active when User Button n is
pressed on the front panel of the device.
• Outputs can also always be triggered by an Ember+ consumer. If this is
the only requirement for an output, then the trigger option should be set
to ‘-’
• The ‘invert trigger’ option allows the state of the GPO to be set up to be
the inverse of the selected trigger.
Output Relay Settings
Fig 8-35: ‘Output Relay Settings’ Section of ‘GPIO Settings’ Webpage
A relay can be selected from the ‘Relay Select’ menu, this allows its
configuration to be viewed and modified, on the AVN portal series devices
only one relay is available.
A number of triggers can be assigned to the relay by selecting them from
the ‘Relay Trigger’ menu, the options available are the same as those
available to GPIO outputs. Multiple triggers can be selected, by dragging the
mouse over the desired triggers in the menu, or by clicking and using ‘Ctrl’
or ‘Shift’ on the keyboard. A ‘Clear All’ button is displayed to the right of
this list which allows all the selected triggers to be removed.
