Page 5: Declaration Of Conformity
CE label marking. - As the integration of a radio module requires wireless technological knowledge, ADEUNIS RF proposes its technical proficiency to its customers for a pre- compliance qualification of end products. In case of no-conformity, ADEUNIS RF will not be held back responsible if this stage has not been realised. -
Page 6: Overview
RF44 User Guide Overview RF44 The A 4 radio transceiver converts data from a serial link into a radio frame to be sent to a similar piece of equipment. The communication is half- duplex. The operating parameters of these radio transceivers can be fully updated through AT commands via the serial link. -

Page 9: Transceiver Operating Mode
RF44 User Guide RSSI Reading The RSSI (Received Strength Signal Indicator) gives an indication for the received power level. It could be accessed with AT commands. -120 -100 -100 -120 Input Power (dBm) The RSSI level is only an indication. Use this level with care due to the dispersion between components. -
Page 10: Serial Data Rate
RF44 User Guide Transceiver or normal mode (serial data are transmitted on radio link) At power up the transceiver is in transceiver mode: it is able to send / receive data to / from the radio link according to its current parameter configuration. Serial data rate This module is only available with one data rate: 19200bps, 8 data bits, 1 stop bit, no parity, no flow control. -
