Function

Description

LED # Board

Color

Main power

Power supply plugged in the 9 - 18 V Power Input

DL401 EVB

Cellular VCC

Cellular module supplied. Main power switch must be switched on

DL400 EVB

Cellular USB

(main UART)

USB cable plugged in the Cellular USB connector (J501) for access to

the main UART interface of cellular module

DL501 EVB

Cellular USB

(main UART)

Green light is on when the SW401 is in “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

Cellular main UART

attach/detach

UART signals of the cellular module are available only on the ADP

board.

DL404 EVB

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 / RX data on the Cellular RS232 connector

DL405 EVB

Cellular RI indicator

RI line turns ON (active low)

DS501 EVB

Cellular CTS indicator

CTS line turns ON (active low)

DS500 EVB

Cellular GPIO1 indicator Green light is activated when cellular GPIO1 is high

DS107 EVB

Cellular GPIO2 indicator Green light is activated when cellular GPIO2 is high

DS105 EVB

Cellular GPIO3 indicator Green light is activated when cellular GPIO3 is high

DS109 EVB

Cellular GPIO4 indicator Green light is activated when cellular GPIO4 is high

DS103 EVB

SARA GNSS Timepulse SARA-R422M8S GNSS TimePulse output

DS139 ADP-R42

Cellular native USB

USB cable plugged in the Cellular native USB connector (J104 / J105)

on the ADP-R4, for access to the USB interface of cellular module

DS100 ADP-R4x

2 For EVK-R422M8S it is recommended to keep this switch on “detach” position.
