Analogue systems

Thanks Bakkis and shm. Yes Bakkis,I am from Greece, born and raised 
in Athens, but have been living in the UK for the last 4 years. I 
have checked my cables and they seem to do that twist to get the red 
line from top to bottom. My RS 110 module cable does not do that 
though, I'll check it out right after work to see if the red wire 
goes from 0V on the module to 0V on the buss board.

Thanks again people, much appreciated.

Peace out.
