Read triggers

It is possible to configure the start and stop of RF operations to GPI triggers. There are two modes available:

• • GPI Trigger: this mode start the RF on all configured antennas for certain amount of time upon receiving a rise events on the selected GPI line

    • GPI line is selected on the AdvanNet

    • Active antennas are the configured antennas

    • RF active time is set to 3500 ms.

Rise events that occur while RF is on will reset the counter without stopping RF operation. Therefore, if rise event keep happening at smaller intervals than the 3500 ms, the RF will never stop.

• • Start/Stop Trigger (Rise/Rise): this mode start the RF on all configured antennas on the first rise event on the selected GPI line, the RF is kept active until a new rise event is received.

    • GPI line is selected on the AdvanNet

    • Active antennas are the configured antennas

(On AdvanNet 2.8.23+ versions)

• • Start/Stop Trigger (Rise/Fall): this mode start the RF on all configured antennas on the first rise event on the selected GPI line, the RF is kept active until a new fall event is received.

    • GPI line is selected on the AdvanNet

    • Active antennas are the configured antennas

Advanced trigger configuration

The GPI Trigger also accepts advanced parameters. The advanced configuration allows:

• • Linking a GPI rise event to a set of antennas

  • Configuring several GPI rise events, each event linked to its set of antennas

  • Define the active RF time

  • The value GPI line is ignored when using the Trigger conf filed.

One possible configuration would be as follows:

{"onTime":15000,"trigger":[{"gpi":1,"conf":{"antennas":"1,2"}},{"gpi":2,"conf":{"antennas":"2"}}]}

The above configuration would:

• • Start RF operation on antennas 1 and 2 on a GPI 1 rise event.

  • Start RF operation on antenna 2 on a GPI 2 rise event.

  • Defines the active RF time to 15000 ms

  • In case a rise event is detected while the RF is active, if required the antenna/s linked to that rise event will be added to the currently running antennas.
