Programmable Universal Audio-Transmitters
Programmable universal audio transmitters with channel-select function and output power control are rated for transmission of audio intelligence via radio channel.
The product designed as an OEM PCB with external microphone, antenna, connector for external power-supply, RC receiver or programmer.
The transmitter modules are designed as a universal module rated for camouflaged operation and hidden installation.
Features:
Programmable parameters from PC:
Operating frequency for each of 16 channels (25 kHz step);
Output power level (2 levels – Hi/Low);
If supply voltage is decreased (below the user’s settings) the RMS transmits a tone signal in audio channel.
If RMS is connected to RC receiver, the functions programmed from RC are:
Channel select (one of 16);
Output power level select (2 levels – Hi/Low).
SPECIFICATIONS:
Operating frequency 417 – 423 MHz
Frequency tuning interval 25 kHz
Frequency stabilization Synthesizer (PLL)
