1.8 Board setup
1.
Insert a SIM card into the SIM card holder (J300 on the EVB).
2.
Connect a cellular antenna provided with the EVK-R6 and EVK-L6 evaluation kit box to the
Primary cellular antenna SMA connector on the ADP-R6 / ADP-L6 (ANT, RF input/output for
transmission and reception of LTE/3G/2G RF signals)
3.
Connect a cellular antenna provided with the EVK-R6 and EVK-L6 evaluation kit box to the
Secondary cellular antenna SMA connector on the ADP-R6 / ADP-L6 (ANT DIV, RF input for the
reception of the LTE / 3G RF signals as per Down-Link Rx diversity and/or MIMO 2x2). Place the
secondary cellular antenna far enough from the primary cellular antenna (more than 20 cm).
4.
If the GNSS functionality is required, connect the GNSS antenna provided with the evaluation kit
to the GNSS antenna SMA connector on the ADP-GNSS. Keep the cellular GNSS detach switch
(SW304) in "GNSS" position. Place the GNSS antenna in a location with a good view of the sky.
5.
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.
6.
Be sure to provide a jumper socket on the Cellular VCC supply jumper (J404 on the EVB) and to
Cellular VCC supply jumper (J109 on the ADP-R6 / ADP-L6). These provide the connection from
the 3.8 V output of the supply circuit from the EVB to the VCC input of the cellular module.
7.
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 is powered but still switched off.
8.
For communication via the cellular module's USB interface, connect a USB cable to the Cellular
native USB (J105) connector (on ADP-R6 / ADP-L6). LED DS100 on ADP-R6 / ADP-L6 lights blue.
Once the switch-on of the cellular module is triggered (see point 11), the COM ports listed in the
Table 6
are enabled by the Windows USB driver after the end of the module boot (details as the
numbering of the ports can be seen via the Windows Device Manager)

Table 6: Cellular USB interface configuration
Run an AT terminal application (such as u-blox m-center), selecting an AT port with these
settings:
Data rate: 115,200 bit/s
o
Data bits: 8

See appendix
A
for how to configure the u-blox m-center AT terminal for Windows.

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 available anyway after the end
of the module boot.
