1 Product Description
FC-302 is a synthesized 5-watt FM transceiver module, 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 GMSK modem.
The application of two-point modulation with good low-frequency response in the radio also makes it a
competitive choice for 9600bps rate data application. Compact dimension and wide range DC support make it
flexible to use.
Features:
• CE, FCC& AS/NZS 4295: 2004 certified
• Programmable 16 channels with Dip-Switch
• Configurable power save feature
• Optional external channel configuration
•GMSK modem
• CTCSS/DCS
• Fast start-up time: 5ms
• SQ programmable via PC
• Pocsag Modulation
• PC programmable & Software tune & Calibration
Applications:
• Industrial telemetry & wireless remote control
• Gas and oil flow monitoring
• Electricity, water and gas utilities
• Earthquake, weather, environmental protection and urban lighting control
• Vehicle tracking and asset tracking systems
• Water monitoring, waste water management and irrigation control
• Railway, police, army automation system
• Aerial defense and fire alarm system
• Wireless Paging system
