Hi. I have a big problem to communicate with TSX Nano. I'm using PL7-07 software under DOS, and i have a cable from this site: http://www.ac-nice.fr/sti/electrotec/22Ibmtotsx.pdf When I try to connect to the PLC the PL7-07 send me an error messeges: Error 2012 and Error 3016 or something like that. Should I blame the cable or what? Please help me. Thank You. I've forgot to write: my PC is Dell Latitude CPx650, and I'm using COM1 port (RS232)
