If the GNSS functionality is required, connect the GNSS antenna provided with the evaluation kit box to the
GNSS antenna
SMA connector (J103 on ADP-GNSS). Put the GNSS antenna in a place with good sky view.
4
Connect the AC / DC +12 V power adapter provided with the Evaluation Kit box to
9 – 18 V Power Input
connector (J400 on EVB). LED DL401 lights blue.
5
Be sure to provide a jumper socket on the
Cellular VCC supply jumper
(J404). This provides 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 whole board power supply, turn the
Main
Power
switch (SW400 on EVB) to ON position.
LED DL400 lights green. The cellular module switches on.
7
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 8 for switch position and LED status):
a.
Connect a USB cable to mini USB connector (
Cellular USB
, J501 on EVB), LED DL501 lights blue
b.
Connect an RS232 cable to DB9 connector (
Cellular RS232
, J500 on EVB)

Table 8: Serial interface configuration
Using the
Cellular USB
connector (case a), two COM ports are enabled with Windows (the numbering of
the COM ports can be seen via the Windows Device Manager)
4
:
o
SARA UART (by default for AT commands and data) is available over the first COM port
o
SARA UART AUX (by default for FW update and diagnostic) is available over the second COM port
8
Run an AT terminal application (e.g. m-center, HyperTerminal) on PC COM-port, with these settings:
o
Data rate: 115200 b/s
o
Data bits: 8
o
Parity: N
o
Stop bits: 1
o
Flow control: HW
See Appendix A for how to configure the u-blox m-center AT terminal for Windows.
9
Connect the headset provided with the evaluation kit box to the
Headset jack
connector (J303 on EVB), if
the audio functionality is required.
