5. 1 Notes on the Use of Level Converters

Level inverters are devices which convert data from one signal type to another, for
instance from RS485 to USB. With the aid of these level converters, a Sunny Boy
Control / Plus or Sunny Boy Control Light can be connected to a PC which does not
have the appropriate interface.

SMA provides the following level converters. These level converters have been tested,
and function with the Sunny Boy Control / Plus and the Sunny Boy Control Light:

RS232/RS485 to USB
- SMA order number: I-7561

RS485 to RS232
- SMA order number: I-7520

Compatibility with all level converters available on the market cannot be guaran-
teed.
