Board Setup - Ublox EVK-L4 User Manual

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 evaluation kit box to the Primary cellular antenna SMA
connector on the ADP-L4 (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-L4 (ANT2, RF input for the reception of the LTE RF signals as per 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 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.
5. 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-L4 (WL ANT, RF input/output for transmission and reception of
Wi-Fi RF signals). Place the Wi-Fi antenna far enough away from cellular antennas (should be more than
20 cm).
6. 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.
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.
9. To switch on the cellular module, press the Cellular Power-On button (SW302 on EVB).
10. For communication via the cellular module's USB interface, connect a USB cable to the Cellular native USB
connector (on ADP-L4). LED DS100 on ADP lights blue.
After the end of the module boot, the COM ports and network interface listed in Table 7 are enabled by the
Windows USB driver (details of the numbering of the ports can be seen via the Windows Device Manager)

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.
