This receiver connects the ProtoThrottle to an ESU CabControl system, Digitrax LNWI, JMRI WiThrottle server (a.k.a. Engine Driver or other phone throttle applications), or other DCC systems that expose a WiThrottle-compatible server, such as the MRC Prodigy WiFi, or DCC-EX.  It receives the wireless signal(s) from multiple ProtoThrottles and translates them to be sent to the command station over the WiFi network.
 
The MRBW-WIFI includes a mini USB cable and 5V/1A USB power supply with a North American plug.
