Declaration of Conformity
Manufacturer’s name: ADEUNIS R.F.
Manufacturer’s address Parc Technologique PRE ROUX IV
38920 CROLLES - FRANCE
declares that the product if used and installed according to the user guide available on
our web site www.adeunis-rf.com
Product Name: ARF54
Product Number(s): ARF7429A
is designed to comply with the RTTE Directive 99/5/EC:
EMC: according to the harmonized standard EN 301 489.
Safety: according to the standard EN 60950-1/2001
Radio: according to harmonized standard EN 300-220 covering essential
Notes: - Conformity has been evaluated according to the procedure
According to the 1999/519/EC recommendation, minimum distance between the product
and the body could be required depending on the module integration.
Warnings: - CE marking applies only to End Products: Because this equipment is only a
subassembly, conformity testing has been reduced (equipment has been design in
accordance to standards but full testing is impossible). Manufacturer of End Products,
based on such a solution, has to insure full conformity to be able to 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 precompliance qualification of end products. In case of no-conformity, ADEUNIS RF will not
be held back responsible if this stage has not been realised.

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
link.
Interface
Mechanical specification
The transceiver is available in only one format: plugged module without
antenna.

General purpose I/O extended functionality
RS485 interface
The S215 register allows enabling the management of the control lines (/RE
and DE lines) of most RS485 buffer. The following figures illustrate the RS485
wiring and the configuration required for activating the DE and /RE
management. Even one line is sufficien t, for m ore flexibility two different lines
could managed the DE and RE RS485 control lines. Hereafter a connection
example with both lines or one line only.
