Connect the AC / DC +12 V power adapter provided with the evaluation kit box to the

18 V
Power Input
connector (J400 on the EVB). LED DL401 lights turn 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
(J102 on the ADP-R8). These provide the connection from the 3.8 V
output of the supply circuit from the EVB to the VCC input of the cellular system of LENA-R8.
7.
For LENA-R8001M10, be sure to provide a jumper socket on the
VCC_GNSS enable jumper
(J701 on the ADP-R8) and to
VBCKP_GNSS enable jumper
(J702 on the ADP-R8). These enable
the 1.8 V supply for the VCC_GNSS and VBCKP_GNSS inputs of the LENA-R8001M10 GNSS
system, using the 3.8 V output of the supply circuit mounted on the EVB.
8.
Be sure to set the
Cellular USB boot slide switch
(J200 on ADP-R8)
on the “NORMAL” position.
If a FW update over USB is
to be executed, set the slide switch on the “USB” position
.
9.
To enable the board power supply, turn the
Main power switch
(SW400 on the EVB) to the ON
position. LED DL400 lights turn green. The cellular system of the LENA-R8 module is powered
but still switched off. The GNSS system of the LENA-R8001M10 module switches on.
10.
For communication via the cellular USB interface, connect a USB cable to the
Cellular native USB
(J700) connector (on ADP-R8). LED700 on ADP-R8 lights turn blue.
Once the switch-on of the cellular system is triggered (see point
), the COM ports listed in the
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 (e.g., the u-blox m-center tool), select the AT port with below settings:
▪
Data rate: 115200 bit/s
▪
Data bits: 8
▪
Parity: N
▪
Stop bits: 1
▪
Flow control: HW
See appendix
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.
