Description: DRF1278DL2 is a type of long range low data rate data radio modem with RS485 Interface based on  SX1278 from Semtech. DRF1278DL2 is a low-cost sub-1 GHz transceiver module designed for operations in the unlicensed ISM (Industrial Scientific Medical) and LPRD bands. Frequency spectrum modulation/demodulation, multi-channel operation, high bandwidth efficiency and anti-blocking performance make DRF1278DL modules easy to realize the robust and reliable wireless link.



DRF1278DL2 is a transparent data radio modem which means the module transfers or receives data from the host with preset data format without encoding/decoding needed so the communication between them is transparent. DRF1278DL offers two types of interfaces for selection which one board only contains one interface. Users can choose RS232 interface DRF1278DL1 or DRF1278DL2 according to the application. Comparing to DRF1278DM module, DRF1278DL doesn’t have star networking function. Users can set both DRF1278DM and DRF128DL module to standard mode to make them compatible.
