Setting up GPIOs and Logic Events

• 2 x GPIs

• 4 x GPOs

• Unlimited Logic Events

• Each GPI/GPO hosts up to 10 different events or actions. These actions can be turned off or on in the Status > Logic page of the CCM.

• 2 x DB 9F connectors on the rear of the Base Station

• For DB 9F pinouts, see Appendix A: Pinouts .

On an input from an external device, an audio route can be established between two entities.

• If an on-air light comes on, the program feed (PGM) can be routed to a Channel or beltpack.

• Use a footswitch to allow the station user to open an audio route to a Channel.

• On an input from a two-way radio, an audio route can be established to a channel (the radio talks to the channel).

GPOs are triggered (sent to an external device) when a Talk, Talk & Listen or a Call comes into a named entity.

• When someone talks to stage announce, an output relay (GPO) is sent to the external stage announce speaker.

• When someone talks to a channel labeled Radio, an output is sent to a 2-way radio.

• When a call signal (Call) comes into a channel, and output is sent to turn on an on-air light.

• An output can be triggered on a crosspoint activation (when someone presses a talk key).

• An input can be used to trigger a call signal.

This example opens a talk route from the Base Station to a Channel when an input occurs on GPI1 (for instance, from a footswitch).

Navigate to Configuration > Logic.

1. On the left panel, click GPI1 to select it.

   

2. Click the Add button in the center panel.

3. Click the Options button to select a Source. Select Edge Base.

4. Click the Options button to select a Destination. Select the required Channel.

5. Click the blue check mark.

6. To label the GPI, click the pencil icon.

7. To test the GPI, or turn it on and off, navigate to Status > Logic. See:
   Logic Page.

In this example you send an output trigger (for example to an external stage announce speaker) on GPO1 when a beltpackTalk is activated on the stage announce (SA) 4-wire port.

1. Navigate to Configuration > Logic.

   

2. On the left panel, click GPO1 to select it.

3. Click the Add button in the center panel.

4. Click the Options button to select a Key Target. Select stage announce (SA).

5. In this case, the On Behavior field defaults to Talk Only.

6. Click the blue check mark.

7. To label the GPO, click the pencil icon.

8. To test the GPO, navigate to Status > Logic. See Logic Page.
