Connecting to a radio

Every operation that talks to a radio (loading, erasing, verifying, configuring, store and forward) works over either connection. Choose the one your radio supports.

Three-wire interface (TWI)

The key fill interface defined by TIA-102.AACD, and the one most radios offer. The unit's security adapter drives it through the Hirose 6-pin port.

1. KFDPro
2. Hirose 6-pin cable, male to male
3. Keyload adapter
4. Radio's accessory or side connector
5. Radio

1. Attach the radio's keyload adapter to the radio. It is specific to the radio model.

2. Connect the Hirose 6-pin cable from the port on the back of the unit to the keyload adapter.

3. Turn the radio on. Many radios show that they are in keyload mode once the adapter is attached; see the radio's own documentation.

4. Check the connection bar on the main menu shows the adapter as connected. Then use Verify communication to confirm the radio answers.

Next: Load keys over three-wire.

USB keyloading

TIA-102.AACD also allows keyloading over a radio's USB port. The radio presents a network link over its USB programming cable, and keys travel over it exactly as they do over the key fill interface. No keyload adapter is needed. Radio authentication and the modem radio for Tactical OTAR always use this connection.

1. KFDPro
2. Radio's USB programming cable, into the USB-A port
3. Radio

1. Turn the radio on.

2. Plug the radio's USB programming cable into the radio, then into the USB-A port on the back of the unit.

3. The USB keyloading screen opens by itself and connects. When it reads Radio at …, ready to load, the radio is connected.

Next: USB keyloading.

Which connection is used

While a radio is connected over USB, operations go to it over USB. The screen titles say so: Load keys, for example, reads Over USB — radio at …. Disconnect the USB radio (the Disconnect button on the USB keyloading screen or on the connection bar) and operations go back to the three-wire adapter.
