Fig. 3.10: RS232 connection to a PC
Connecting a PC to the Sunny Boy Control requires a so-called null modem cable
(SMA order no. 36-5001).
The PC-to-Sunny Boy Control connection must be made using the null
modem cable included with the Sunny Boy Control. This connection can-
not be made using a regular one-to-one cable.
If your PC’s DB9 connector (COM1) is already taken, such as by a serial PC mouse,
or if it has only a DB25 connector, you will also need a DB25-DB9 adapter (SMA
order no. 36-5010).
Alternatively, you can prepare your own cables according to the following tables
and diagrams.
