Software installation
The USB drivers for Windows operating systems are available with the EVK-R4. Executable files can
be downloaded from
and saved to any location on the computer hard
drive. The installation can be started by running the executable file on a computer with the Windows
operating system.

Board setup
1.
Insert a SIM card into the
SIM card holder
(J300 on the EVB).
2.
Connect the cellular antenna provided with the evaluation kit box to the
Cellular antenna
SMA
connector on the ADP-R4 (ANT connector for transmission and reception of LTE RF signals)
3.
If the GNSS functionality is required:
3.1.
For the EVK-R410M and EVK-R412M, connect the GNSS antenna provided with the
evaluation kit box to the
GNSS antenna
SMA connector on the ADP-GNSS (J208); keep the
cellular GNSS detach switch (SW304) in “GNSS” position.
3.2.
For the EVK-R422M8S, connect the GNSS antenna provided with the evaluation kit box to
the
GNSS antenna
SMA connector on the ADP-R422M8S (J112); keep the cellular GNSS
detach switch (SW304) in “detach” position.
Place the GNSS antenna in a location with a good view of the sky.

.
4.
Connect the AC / DC +12 V power adapter provided with the evaluation kit box to the
9
–
18 V
Power input
connector (J400 on the EVB). The LED DL401 lights blue.
5.
Be sure to provide a jumper socket on the
Cellular VCC supply jumpers
(the J404 on the EVB,
and the J109 on the ADP-R42). These jumpers provide the connection from the 3.8 V output of
the supply circuit on the EVB to the VCC input of the module.
6.
To enable the board power supply, turn the
Main power switch
(SW400 on the EVB) to the ON
position. The LED DL400 lights green.
7.
For communication via the cellular module’s UART interface, the following connections are
allowed and can be alternatively enabled in a mutually exclusive way (see
position and LED status):
7.1.
Connect a USB cable to the mini USB connector on the EVB (
Cellular USB
, J501). The LED
DL501 lights blue. When a USB cable is connected to the mini USB connector, two COM
ports are enabled in Windows (the numbering of the COM ports can be seen via the
Windows Device Manager). The main UART interface is available over the first COM port.
The GNSS UART output of SARA-R422M8S is available over the second COM port.
7.2.
Connect an RS232 cable to the DB9 connector (
Cellular RS232
, J500 on EVB).
7.3.
Connect a USB cable to the mini USB connector on the ADP-R42 (
Cellular USB
, J201). The
LED DS201 lights blue. When a USB cable is connected to this mini USB connector, two
COM ports are enabled in Windows: the two UART interfaces of the SARA-R42 series
modules are respectively available over the two numbered COM ports opened by the driver
(to enable the two UART interfaces, see the AT command manual
, +USIO AT command).

Supply for the NEO-M8N GNSS module can be provided mounting the 0R jumper R106 and removing the 0R jumper R107 on
the ADP-GNSS
