If it has a 240 option on both primary and secondary, would not using the 240 taps on both make it a 1:1 so putting 120 in would get 120 out? --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
