What is the function of ACE909-2 RS 232 / RS 485 converter?

Published date: 15 March 2021

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.
