Board setup
1.
Insert a SIM card into the
SIM card holder
(J300 on the EVB).
2.
Connect a cellular antenna provided with the evaluation kit box to the
Primary cellular antenna
SMA connector on the ADP-L2 (ANT1, RF input/output for transmission and reception of
LTE/3G/2G RF signals).
3.
Connect a cellular antenna provided with the evaluation kit box to the
Secondary cellular antenna
SMA connector on the ADP-L2 (ANT2, RF input for the reception of the LTE RF signals as per the
Down-Link MIMO 2 x 2 and for the reception of the 3G RF signals as per the Down-Link Rx
diversity). Place the secondary cellular antenna far enough from the primary cellular antenna
(should be more than 20 cm).
4.
If the Wi-Fi functionality is required, connect the Wi-Fi antenna provided with the evaluation kit
box to the
Wi-Fi antenna
SMA connector on the ADP-L2 (ANT WL). Place the Wi-Fi antenna far
enough from the cellular antennas (should be more than 20 cm).
☞
Wi-Fi functionality is available on the EVK-L2 for TOBY-L2 product versions "02", "62" onwards
5.
If the GNSS functionality is required, connect the GNSS antenna provided with the evaluation kit
box to the
GNSS antenna
SMA connector on the EVB. Place the GNSS antenna in a location with
good sky view.
☞
Interface to the GNSS module is not supported by TOBY-L2 modules

.
6.
Connect the AC / DC +12 V power adapter provided with the evaluation kit to the
9
–
18 V Power
Input
connector (J400 on the EVB). LED DL401 lights blue.
7.
Be sure to provide a jumper socket on the
Cellular VCC supply jumper
(J404 on the EVB). This
provides the connection from the 3.8 V output of the supply circuit on the EVB to the VCC input
of the module.
8.
To enable the board power supply, turn the
Main power switch
(SW400 on the EVB) to the ON
position. LED DL400 lights green. The cellular module switches on.
9.
For communication via USB, connect the USB cable to the
Cellular native USB
connector (J100
on ADP). LED DS100 on ADP lights blue. After the end of the module boot, the following devices
are by default enabled with Windows (details as the ports numbering can be seen via the
Windows Device Manager)

Supply for the GNSS module can be provided by mounting the 0R jumper R106 and removing the 0R jumper R107 on the ADP-
GNSS.
5
A message of “driver installation fail” may appear on Windows if the
USB cable has been connected before the end of the
module boot, but this can be ignored as the normal operating functionality of the module will be anyway available after the end
of the module boot.
