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. DRF1278DL2 only has RS485 interface and DRF1278DL1 has RS232 interface . Comparing to DRF1278DM module, DRF1278DL2 doesn’t have star networking function. Users can set both DRF1278DM and DRF1278DL2 modules to standard mode to make them compatible.
