GPIO settings
GPIO Pin [1..4] Mode
The four GPIO pins are configured individually. The state can be retrieved by "xStatus GPIO Pin
[1..4] State". The default pin state is High (+12 V). When activated as output, they are set to 0 V.
To activate them as input, they must be pulled down to 0 V.
Requires user role: ADMIN
Value space: <InputNoAction/OutputManualState/OutputInCall/OutputMicrophonesMuted/
OutputPresentationOn/OutputAllCallsEncrypted/OutputStandbyActive/InputMuteMicrophones>
InputNoAction: The pin state can be set, but no operation is performed.
OutputManualState: The pin state can be set by "xCommand GPIO ManualState Set PinX:
<High/Low>" (to +12 V or 0 V, respectively).
OutputInCall: The pin is activated when in call, deactivated when not in call.
OutputMicrophonesMuted: The pin is activated when microphones are muted, deactivated
when not muted.
OutputPresentationOn: The pin is activated when presentation is active, deactivated when
presentation is not active.
OutputAllCallsEncrypted: The pin is activated when all calls are encrypted, deactivated when
one or more calls are not encrypted.
OutputStandbyActive: The pin is activated when the system is in standby mode, deactivated
when no longer in standby.
InputMuteMicrophones: When the pin is activated (0 V), the microphones will be muted.
When deactivated (+ 12 V), the microphones are unmuted.
