The bus connection module RER 115 acts as an interfacing unit between the terminal units REC 523, REM 54_ or REF 54_ and the twisted-pair FTT-10A LON ® bus. The RER 115 is not a stand alone device; a terminal unit is always required.
The RER 115 module is plugged into the D-type connector on the rear plate of the terminal unit. The module can be used together with terminal units provided with a 9-pin D-type connector.
