You have now connected the gateway connector to your desktop app.

Step 6: Connect a Gateway Connector Device

You will need a RoIP gateway connector hardware device like this one. Connect your computer to the gateway connector device via the computer’s serial port. Connect the gateway connector device to your base station via your base station’s programming cable.

Using the desktop app

To add an additional gateway connector, click the + icon in the top right corner.

Devices

Set the audio input and output as the gateway connector device (otherwise audio will go from your computer’s speaker and mic).

The lights on a gateway connector device will flash when you add it as an input/output. This is helpful if you have multiple gateway connector devices connected to your computer, as it will indicate which gateway connector you’re connecting to which device.

Record Trigger

Here you can adjust the volume settings for the gateway connector device.

Input Volume shows the volume of the audio that the computer is receiving from the gateway connector device. Voice Activation (sometimes called a VOX switch) enables you to set the volume threshold above which audio is transmitted to smartphones on the channel. Auto Voice Activation automatically sets the threshold level to 0% or 1% and should be used in most cases. Select Manual Voice Activation only if you experience static that triggers audio playback on smartphones when LMR radios are not transmitting.

Status

Checked boxes in this section indicate that a feature is active/taking place.

Channels

This section shows all the channels to which you have added the gateway connector device (from the Admin Portal earlier). This is also where you select which channel you want the gateway connector to be active on. A gateway connector can only be active on one channel at a time.

Each gateway connector must be connected to one radio base station. Whichever channel the base station is on will be the Land Mobile Radio (LMR) channel connected to the MODULO channel you select. Some gateway connector devices can have multiple gateway connectors in one chassis. The number of inputs/outputs on the chassis will indicate the number of gateway connectors it contains.

Your gateway connector is now ready for use!
