Usually sserial errors like that are related to power issues on the 7I77. Make sure that the 7I77 and 5I25 are jumpered for external 7I77 5V power (not cable power) and that the external 5V suppled to the 7I77 is within 5% margins Peter Wallace Mesa Electronics ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
