[Introduction]：E95-DTU (900SL30-232) is a wireless data radio using military-grade LoRa modulation technology. It has multiple transmission modes and operates in the frequency band (850.125MHz~930.125MHz) (default 868.125MHz). The data radio provides a transparent RS232 interface, uses a plastic shell, a guide rail installation structure, and supports DC 8~28V voltage input. LoRa spread spectrum technology will bring a longer communication distance and has the advantage of strong anti-interference ability.

Frequency range and number of channels
| Model specifications | default frequency | Frequency band range | channel spacing | Number of channels |
| Hz | Hz | Hz | ||
| E95-DTU(900SL 30-232 ) | 868.125M | 850.125~930.125M | 1M | 81, half duplex |
Note: When using multiple groups of digital radio stations to communicate one-to-one at the same time in the same area, it is recommended that each group of digital radio stations set a channel spacing of more than 2MHz.
Transmit power level
| Model specifications | 30dBm | 27dBm | 24dBm | 21dBm |
| E95-DTU(900SL30-232) | Factory default | √ | √ | √ |
Note: The lower the transmit power, the closer the transmission distance, but the operating current will not decrease in the same proportion. It is recommended to use the maximum transmit power.
Air speed class
| Model specifications | Default air rate bps | Number of levels kbps | Air speed class |
| E95-DTU(900SL30-232) | 2.4k | 6 | 2.4, 4.8, 9.6, 19.2, 38.4, 62.5 |
Note: The higher the air speed setting, the faster the transmission rate and the shorter the transmission distance; therefore, when the speed meets the usage requirements, it is recommended that the lower the air speed, the better.
Current parameters
| Model specifications | Emission current mA | Receive current mA | Sleep current mA |
| 12V | 12V | 12V | |
| E95-DTU(900SL30-232) | 158.4 | 15.8 | 7.73 |
Note: It is recommended to keep more than 50% current margin when selecting the power supply, which is beneficial to the long-term and stable operation of the radio.
