Posted 18 Jul 2014 (edited) Hello. This is old topic find on: http://forums.mrplc.com/index.php?showtopic=14004&st=0&p=68824&hl=2-wire&fromsearch=1entry68824 Equipment: Cj1m Cpu11, SCU41-V1, MOXA Nport 5150 (2-wire setting), Multiway (from Viskovi?). The problem persists. Does anybody manage to use SCU41 in 2-wire SLAVE mode? I just cant make it to work.... In 4-Wire mode everything works perfectly.... 2-wire settings: Switch of SCU to 2-wire, MOXA set to RS485 2-Wire 4-wire settings: Switch of SCU to 4-wire, MOXA set to RS485 4-Wire I have also played with different setting for CTS but nothing works.... Below are pictures of comm with 2-wire and comm with 4-wire Edited 18 Jul 2014 by manowar Share this post Link to post Share on other sites
