The RDX Radio Interface

RDX Dynamic View

The RDX Radio Interface is used for linking portable radios into a Green-GO system, featuring a full-color OLED display that shows information about channels; configurable by the four buttons on the front of the device with access to many of the same functions and features as most other Green-GO devices.

Tx, Rx and PTT emulation is presented as a D-SUB 9 connector. Powered via PoE through a network cable connected to the devices Ethercon port.

A bespoke cable assembly is required between the interface and a captive radio of your choice, please see D-Sub 9 pin-outs for details on termination and Example adapter schematics.

What's in the box?

The Green-GO RDX radio interface comes with the following package contents:

  • 1 x Green-GO RDX radio interface
  • 1 x Printed quickstart guide
Optional Green-GO accessories
  • Green-GO PoE network switches

The user interface

RDX User Interface

The user interface of the RDX radio interface is compact and straightforward:

  1. The user linked to the device is shown on top of the screen.
  2. Currently enabled channels and the input level coming from a connected radio is shown in the middle of the screen.
  3. On the bottom of the screen, the channel(s) receiving communication from the Green-GO network is displayed with the received signal level going to the connected radio.

Interfacing with a radio

The Green-GO RDX radio interface can interface with a broad range of two-way radios.

The device doesn't come with any adapter cables. However, with the connection schemes and pinouts below, you can create a connector cable for the radio type that you wish to use. The cable will connect the D-Sub 9 connector on the back of the RDX interface with the headset connector found on the radio.

Notice: To avoid signal loss, your adapter cable should be shielded and no longer than 1.5 meters.

A correctly build adapter cable is cruical for correct operation. So, to get a better understanding of the following pin-out schemes, it is good to know how the D-Sub 9 pins are actually connected internally:

RDX GPIO Internals

As soon as the RDX radio interface receives audio on any channel from the Green-GO network, a push-to-talk relay is activated that takes care of the keying of the radio. Any audio received via the connected two-way radio is automatically transmitted to any channel using the Autotalk channel mode.

Adjust the physical connection

RDX Jumper Switches

As seen in the device diagram above, the two available jumper switches on the back of the device can influence how the audio going to the connected two-way radio is transmitted:

Switch 1
Switch 1 acts as an attenuator for the transmitted audio signal.
Switch 2
Enables a path for a DC voltage supplied by the radio.

Configure transmitting channels

Depending on your configuration no audio may be tranmitted to your Green-GO network. To change this you need to configure the mode of one or more of the user's channels to Autotalk.

Using the channel mode Autotalk automatically enables a channel as soon as audio from the two-way radio reaches or overcomes the configured Gate threshold.

               └──> Channel Mode: Autotalk # (1)!
  1. Defines the operation mode of the channel

Adjust the PTT behavior

Depending on your situation, adjusting your Green-GO RDX interface's TX mode may be required. By default, a Green-GO RDX interface will activate its PTT relay as soon as a remote Green-GO device opens a channel to the interface (TX mode: TX Talk). This will usually block the radio channel until the channel is closed again and the local Active Time has run out.

Configuring the TX mode to TX VOX will change this behavior and only trigger the PTT relay if actual audio is received from the Green-GO network. Meaning remote Green-GO devices have to overcome their local Gate threshold before activating the PTT relay.

        └──> TX mode # (1)!
  1. Defines how the PTT relay is triggered. TX Talk triggers for the complete duration a channel is enabled. TX VOX triggers when receiving actual audio.

The setup menu

The setup menu allows local access to almost all user and device configuration properties. All changes in the setup menu are done and stored locally on the device but can be easily synced back into the configuration file using the Green-GO Control software. These settings are also persistent on the device unless overwritten.

One Channel Interfaces Setup Menu

The setup menu is accessed by sequentially pressing both left-hand buttons (Button 1+Button 2).

One Channel Interfaces Setup Menu

Once inside the setup menu, the left-hand buttons will change function:

The Button 1 (top-left) confirms a selection or value while the Button 2 (bottom-left) can be used to either exit the current (sub-) menu or cancel a value selection.

The right-hand buttons (Button 3 and Button 4) are used to move a selection or change a selected value.

A (sub-) menu can be exited either the the menu entry Exit or Cancel, and alternatively with the Button 2 (bottom-left).

Access to the setup menu can be restricted by configuring the security options of a configuration file or user with the help of the Green-GO Control software. In restrictive security configurations, the user may be asked to enter the Tech Pincode before access is given.

Tip: More information on security options can be found here.
