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
RF54 User Guide Overview The ARF54 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 (serial link, radio management…) can be fully updated through AT commands via the serial... - Page 7 RF54 User Guide The PCB width is 12/10 mm Figure 1: Plugged module mechanical feature This module has been designed to be plugged (as describe above). If this assembly doesn’t suit your requirement, please have a look to Annex 1 (mainly for horizontal mounting).

Changing the /ENABLE485 (GPIO7) when the transceiver is already running will not be taken in account. • when activating the RS485 interface the GPIO5 will be set as an output.
- Page 11 RF54 User Guide By default, the DE and RE lines are asserted LOW, allowing the reception of characters from the RS485 differential bus. The DE and RE lines are asserted HIGH only when one or several characters have to be transmitted over the RS485 differential bus: when a radio frame is demodulated, the lines are asserted HIGH and then the data extracted from the radio frame are sent to the module TXD line and therefore to the RS485 differential bus.

Page 15: Transceiver Operating Mode
RF54 User Guide Transceiver operating mode Two operating modes are available : Command mode (usage of AT commands) 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. -

RF54 User Guide Exiting command mode (return back in transceiver mode): send the serial command ATO <cr> Transceiver mode In transceiver mode, two protocols are available: Transparent mode, without flow control. Addressed mode, with flow control (see register S216) The communication is always half-duplex. The radio transmission is processed prior to the radio reception (when the transceiver is sending a radio frame, it is not able to decode any incoming radio frame). -
Page 17: Transparent Mode

The buffered data are sent in a radio frame (the RF modulation is started) when almost one of the following conditions occurs: if a break (silence greater than S217 timeout) is detected on the incoming serial flow (no more data to be sent). -
