BatiBUS


Original standard proposed by Merlin Gerin, now open to “club” membership.  A relatively simple low cost protocol not relying on dedicated chips.  Connection structure allows any arrangement of cables making it extremely flexible in matching building requirements.  A large number of devices may be connected to the network using simple guidelines to maintain reliability of exchange. The same guidelines ensure that the time taken for messages to arrive at their destination remains imperceptible to the user.  The media used is a twisted pair cable with a 15 V line voltage and addresses are assigned as part of the commissioning process.

Predominately used in France and described in the French Standard NFC 46620, it provides layers 1, 2 and 7 of the OSI Model.  Batibus recently formed an alliance with EIB.  More information can be found at www.invirtou.com/batibus.
