GPIO: Examples and Step-By-Step Set Up
Setting up a Partyline/2-Wire relay to a radio (VOX trigger).
This example shows how to send a GPO (General Purpose Output) trigger to a third party radio when audio comes in from an Encore RS701 beltpack. This can be used to open audio transmission on the radio; equivalent to pressing the Push To Talk (PTT) button on the radio.
The GPO is triggered by LQ models that have a GPO port; LQ-4WG2, GQ-R2WG8 and LQ-R2W4+4WG4.

Note:
|
For this configuration Link Group must already be established. See Creating a Link-Group for more information. |
- In port settings, on the device and port connected to the belpack, set the VOX (audio detection) to trigger Network Control Event 1
- On the device and port connected to the radio, set the GPO to trigger on Network Control Event 1
- Bring both ports together into a Channel
- When audio comes in from the beltpack, the GPO will fire. You can test this relay using the TEST button.
- Connect the beltpack. Connecting 2-wire Equipment
- Set Network Control Events in the CCM (Core Configuration Manager)
- Set beltpack port.
- Set radio port.
-
Once you have set up the ports, navigate to Assignments in the CCM and put ports into a Channel.

Note:
|
You will see audio and Network Control Event status LED light when audio comes into the Channel and triggers Network Control Event 1. |
This example shows how to set up a Call button press on an Encore 701 beltpack to open communication with a third party radio.
Call signals are automatically passed when using 2-Wire equipment, so no configuration of the beltpack port is necessary when using a CALL to trigger a relay to a radio.
Beltpack to radio on Call button press
- Connect beltpack as above.
- In the CCM, navigate to the port where the radio is connected (see Step 2.b of Example #1 above). Select Channel Call Event on the GPO trigger.
- The output will fire on any Call event in the Channel.

Note:
|
You can also set the beltpack to do 'call on talk' by setting dip switch 5 on the beltpack. See RS-701 datasheet available from the Clear-Com website, www.clearcom.com. |
