The functionality of the simulated KMA28 Audio Amplifier/Intercom/Marker Beacon Receiver is extremely close to the original product. Users can identify which receivers are selected by noting which of the green switch LEDs are illuminated. Push buttons labeled Nav 1, Nav 2, DME, MKR (Marker), ADF, AUX (auxiliary), and SPR (Speaker) are “latched” type switches. A 40-pole flatcable including connectors to connect to the RSC board is included. You will need the Radio Stack Controller Board to connect this module to your PC. The dimensions are: (WxDxH): 160x50x38 mm. / 6.3×1.968×1.496”
You will need the Mounting Set or the Radio Stack Cabinet in order to mount the radio modules.
