Fig. 3.15: RS485 connection between a PC and several Sunny Boy Controls
The following requirements must be met to establish a connection between several
Sunny Boy Controls
and a PC.
•
Each Sunny Boy Control has an RS485 Piggy-Back connected to the “PC
(COM2)” connector.
•
A COM port is available on the PC and an RS485-RS232 interface con-
verter is connected to it. SMA recommends an I-7520 interface converter
from IPC. SMA’s Sunny Boy Hotline does not support the use of interface
converters other than the recommended one.
•
The plug-in jumpers B and C (Pull-Up / Pull-Down resistors) may only be
plugged in one Sunny Boy Control. In case of the usage of an I-7520 in-
terface converter the plug-in jumpers B and C have to be removed in all
Sunny Boy Control.
•
A suitable cable (of the LiYCY type) is correctly terminated on both ends
and does not exceed a length of 1,200 m / 4,000 ft.
