RF to Data interface module is compatible with Directed 5 volt LE and SST transceiver (IVU) as well as some Astrostart and Autostart transceivers. The 2-way module acts as a hub to add long range 1-way or 2-way remote control to any "Remote Start Ready" XPRESSKIT applications. Plugs directly into DBALL or XK09 to add remote controls.
