Function PE 00 The ACE909 2 converter is used to connect a master central computer equipped with a V24 RS 232 type serial port as a standard feature to stations connected to a 2 wire RS 485 network. Without requiring any flow control signals after the parameters are set the ACE909 2 converter performs conversion network polarization and automatic dispatching of frames between the master and the stations by two way simplex half duplex single pair transmission. The ACE909 2 converter also provides a 12 V DC or 24 V DC supply for the distributed power supply of the Sepam ACE949 2 ACE959 or ACE969 interfaces. The communication settings should be the same as the Sepam and supervisor communication settings.
