RS-232 UHF VHF 5W Data Radio Modem with 4FSK Modem FC-302 for Street Light
Abstract
FC-302 is a synthesized 5-watt FM UHF (450-490MHz)/ VHF (136-174MHz) Wireless Data Radio, which is designed for data transportation and voice communication. For the voice communication, it can support selected pre-emphasis, squelch and audio amplifier. The radio is PLL (Phase Lock Loop Synthesizer) /microprocessor controlled with optional FSK, GMSK, 4FSK modem, and 16 channels. The application of two-point modulation with good low-frequency response in the radio also makes it a competitive choice for 1200-19200bps rate data application. Compact dimension and wide range DC support make it flexible to use. CE FCC & IC certified.
