Description
LED # Board
Color
Main power
Power supply plugged in the
9 - 18 V Power Input
DL401 EVB-WL3
Cellular VCC
Cellular module supplied.
Main power switch
must be switched on.
DL400 EVB-WL3
Cellular USB
(main UART)
USB cable plugged in the
Cellular USB
connector (J501) for access to
the main UART interface of the cellular module
DL501 EVB-WL3
Cellular USB
(main UART)
Green light is on when the SW401 is i
n “on
-
board” position, and
when
the cellular module main UART is routed to the
Cellular USB
connector.
Red light blinks at UART TX or RX data on the
Cellular USB
connector.
DL403 EVB-WL3
Cellular main UART
attach/detach
UART signals of the cellular module are available only on the ADP board. DL404 EVB-WL3
Cellular RS232
(main UART)
Green light is on when the main UART of the cellular module is routed to
the
Cellular RS232
connector (J500).
Red light blinks at UART TX or RX data on the
Cellular RS232
connector.
DL405 EVB-WL3
Cellular RI indicator
RI line turns ON (active low)
DS501 EVB-WL3
Cellular CTS indicator CTS line turns ON (active low)
DS500 EVB-WL3
Cellular GPIO1 indicator Green light is activated when cellular GPIO1 is high
DS107 EVB-WL3
