GMAC Posted June 30 Share Posted June 30 A friend bought an ECCO 3.5kw and lithium but just to find out it only has RS232 port even if it's advertised with 485 port Ecco 3.5kw has an RS232 port look like for dongle but no RS485 port for communication to battery but yet setting for lithium communication . Has any one successful got the RS232 port to communicate with battery RS485 or can port . Quote Link to comment Share on other sites More sharing options...

Has any one successful got the RS232 port to communicate with battery RS485 or can port . As main difference besides using different signal levels, RS485 uses differential signaling and half duplex while RS232 is single ended and full duplex (separate Rx and Tx lines).
