3.7.3 Simple Connection to PC
A PC is connected to a Sunny Island via RS232 with an ordinary serial data trans-
mission cable (null modem cable, SMA order code “36-5001 “).
If your PC is equipped with DB25 plugs or if only a DB25 plug is free (e. g. the COM1
DB9 plug is already used by a serial PC mouse) you additionally require a DB25/DB9
adapter (SMA order code 36-5010).
You can also manufacture such a cable yourself following the description in the man-
ual for the Sunny Boy Control (Chapter 3.2, PC interface). You will find this manual
on our website www.SMA.de for download.
