Overview HX-U202 is an IP67 classified UHF radio modem with a high power(35W) transmitter and wide tuning range. It is designed for easy mobile use in demanding field conditions. According to the IP67 standard, the casing and connectors of the U202 are waterproof secured against dust. In addition to the high output power and wide tuning range, the channel spacing is also selectable to be 12.5 or 25 kHz. U202 is equipped with a digital tube, four LED and three keystrokes, used to indicate the current operating status, as well as for changing the operating channel and power level of the radio modem. U202 radio modems provide reliable, real-time data communications over distances ranging from tens or hundreds of meters up to around 20 kilometers. U202 radio modem networks are flexible, easy to expand and can cover a wide variety of solutions from simple point-to-point connections to large networks comprising hundreds of modems. Even for expanded networks, only one operating frequency is required. □ Channel switch key a Channel screen 0 Power switch key Q High-power indicator 0 Low-power indicator 0 Transmitting indicator a Turn on indicator □ ON/OFF key Specifications Transceiver Frequency range Tuning range Channel spacing Frequency stability Type of emission Communication mode Link protocols Transmitter Carrier power Carrier power stability TX Duty 25W 5W 5W/10W/25W/35W/@50 ohm ±1.5dB 100% @25°C/@35°C 40% 30 min/20 min no limit no limit/1 hour no limit Same channel rejection >12dB Adjuacent channel selectivity >[email protected]/>52dB@25kHz Intermodulation attenuation >60dB Data modem Electrical interface Interface connector Data speed of serial interface Data speed of radio interface Data format General Operating voltage Power consumption Transmitting mode: Operation temperature Store temperature Antenna connector Construction Size(HxWxD) Weight IP classification SOUTH SURVEYING S.
