Ebyte E90-DTU(900SL33) military data modem radio transmission military-grade LoRa modulation technology
E90-DTU (900SL33) is a military data modem radio using military-grade LoRa modulation technology. It has multiple transmission methods. The default working frequency band is 868.125MHz, and it supports 8-28V voltage input. The module has a software FEC forward error correction algorithm that can actively correct interfered data packets, greatly improving reliability and transmission distance. Carrier Frequency: 850.125~930.125MHz Transmission Power: 33dBm Communication Distance: 16km Interface Type: RS232/RS485 Weight: 150.0g Product Size: 82*62*25mm Model Frequency Power Distance Specification Recommend application scenarios Hz W km E90-DTU(900SL 33) 868.125MH z 2 16 LoRa amplification of anti-interference Suitable for distant, easily disturbed environments ★ Note: In sunny weather, no shelter in the open environment. 12V / 2A power supply, 5 dBi suction cup antenna. the antenna is 2 meters away from the ground height, using the factory default parameters. Frequency range and channel number Model Default Frequency Band Range Channel Spacing Description Hz Hz Hz E90-DTU(900SL33) 868.125MHz 850.125- 930.125MHz IM 81. Half duplex ★ Note: In the same area, multiple sets of transmission stations are used to communicate one to one at the same time. It is sueeested that the channel interval be set above 2 MHz. Transmit power level Model 2W 1W 500m W 250m W E90-DTU(900SL33) Factory default √ √ √ ★ Note: The lower the transmission power is, the closer the transmission distance is, but the working current will not decrease in the same proportion, so it is recommended to use the maximum transmission power. Air rate grade Model Default Equal series Air rate grade bps bps E90-DTU(900SL33) 2.4k 6 2.4、4.8、9.6、19.2、38.4、62.5k ★ Note: The higher the air speed setting, the faster the transmission rate, and the closer the transmission distance; so if the rate meets the usage requirements, the lower the air speed, the better. Current parameters Model Emission current mA Waiting current mA 12V 24V 12V 24V E90-DTU(900SL33) 650 330 10 6 Receiving length and subcontracting method Model Cache size Subcontracting method E90-DTU(900SL33) 1000 Bytes Can be sent by instruction subcontracting 32 / 64 / 128 / 240 bytes ★ Note: 1. If the single data received by the radio station is greater than the single package capacity, the excess part of the data will be automatically allocated to the second transmission until the transmission is completed; 2. The single received data should not be greater than the cache capacity. Company Profile Ebyte Company Profile Development Testin RF_Setting Communication test Product Descriptio Manual
