The appropriate macro is activated either when the connection is made (GPI On), or when it is switched off (GPI Off)
relative to a ground pin on the 44-way D type connector.
The GPI input macros defined for a system are stored in /home/params/gpi.xml
4.10.2 GPI Outputs and Events
A GPI output port can be used as an output to trigger any external device based on the occurrence of an event within
the LGK-3901/DSK-3901 card. The active status (on) is defined by the output being internally pulled to ground.
The events that trigger GPI outputs on or off are configured via the front panel menu:
• Select the GPI Output (ON or OFF) to configure:
• SETUP > GPI > GPI OUTPUTS > GPI OUT x ON
• SETUP > GPI > GPI OUTPUTS > GPI OUT x OFF
• Here “x” represents the GPI number from 0 to 7
• If the GPI is unused, > NONE < will be displayed on the front panel
• Use the joystick arrows [+] and [–] to select the event that should control the appropriate GPI output port
Events triggers can be set to a range of different good and bad states relating to:
• External reference signal
• SDI video inputs
• Temperature
• Voltages
• Compact Flash usage
• Network interface
• Backplane presence
• DSK fader position and fade-to-black position
• Store loading
• EAS running or stopped
• Audio mixing, fade to silence, and voice-overs
• Audio loss or type change (embedded or external AES)
Note: The full list of event actions that can trigger GPI Outputs is shown in ANNEX 2
GPI outputs can also be set on or off virtually via the OPERATE > GPI OUTPUT front panel menu or automation.
The GPI output events defined for a system are stored in /home/params/gpi.xml
