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; con2gurable 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,

1 PoE Powered 10/100 Mbps Neutrik EtherCON
The 10/100 Mbps Neutrik EtherCON serves as power input and connection to the local
network.
1 D-Sub 9 Radio Connector
An external radio is connected to the D-Sub 9 connector. Both audio and PTT control are
transmitted to the headset connector of any radio.
2 Jumper Switches
The two jumper switches can be used to adjust the physical connection to the external
radio.
The 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:
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

back into the con2guration 2le using the Green-GO Control software. These settings are also
persistent on the device unless overwritten.
The setup menu is accessed by sequentially pressing both left-hand buttons (
