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-G450 (J0501), RF input/output for transmission and reception of 2G RF
signals)
3.
If the GNSS functionality is required, connect the GNSS antenna provided with the evaluation kit
box to the GNSS antenna SMA connector on the ADP-GNSS. Place the 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). LED DL401 lights blue.
5.
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.
6.
To enable the board power supply, turn the Main power switch (SW400 on the EVB) to the ON
position. LED DL400 lights green.
7.
To switch on the cellular module, press the Cellular power-on button (SW302 on EVB).
8.
For communication via UART interface of the cellular module, the following connections are
allowed and can be alternatively enabled in a mutually exclusive way (see
Table 6
for switch
position and LED status):
8.1.
Connect a USB cable to mini USB connector (Cellular USB, J501 on EVB), LED DL501 lights
blue
8.2.
Connect an RS232 cable to DB9 connector (Cellular RS232, J500 on EVB)

Table 6: Serial interface configuration
Using the Cellular USB connector (case 8.1), two COM ports are enabled with Windows (the
numbering of the COM ports can be seen via the Windows Device Manager):
o
SARA UART (by default for AT commands and data) is available over the first COM port
o
SARA UART FT (by default for FW update and diagnostic) is available over the second COM
port
9.
Run an AT terminal application (e.g. the u-blox m-center tool) selecting an AT port, with these
settings:
o
Data rate: 115'200 bit/s
o
Data bits: 8
o
Parity: none
o
Stop bits: 1
o
Flow control: hardware
See Appendix
A
for how to configure the u-blox m-center AT terminal for Windows.
10.
If the audio functionality is required, connect the headset provided with the evaluation kit box to
the Headset jack connector (J303 on EVB).
