Sunny WebBox is 
unable to connect via 
DSL router.
The DSL routers of some 
manufacturers may be 
disconnected when the DSL 
router switches to energy saving 
mode.
Disable the energy saving mode of the 
DSL router.
Use the "LAN 1" port of the DSL router 
since the energy saving mode for this 
port is usually disabled by default.
Sunny WebBox is 
unable to detect 
devices connected to 
the RS485 bus.

configured properly.
Make sure the data transmission 
protocol and the baud rate for the

Make sure the RS485 cable is properly 
connected to the Sunny WebBox. Check 
all connections (see Section 6.9.2 
"Connecting the Sunny WebBox to the 
RS485 Communication Bus" (page 34)).
Check the termination and signal biasing 
of the RS485 communication bus (see 
Section 6.9.2 "Connecting the Sunny 
WebBox to the RS485 Communication 
Bus" (page 34)).
