RFDM Image
   The Technovision RFDM is an Industrial Grade RS-232 controllable device that can demodulate any RF frequency signals up to 801.25 MHz into separate NTSC video and line level audio signals. These signals can then be routed through a video switcher to integrate cable signals into kiosk applications.
   The RFDM can also be used as a stand-alone device to automatically select and display RF channels on any NTSC video monitor.
