9. For communication via the cellular module’s UART interface s, the following connections are
allowed and can be alternatively enabled in a mutually exclusive way (see Table 7 for the switch
position and LED status, and see Figure 1 and Figure 3 for the location of the related connectors,
slide switches and the 3-way UARTs ’ routing switch J248):
a. Connect a USB cable to the mini-USB connector ( Cellular USB Main UART , J501 on EVB).
The LED DL501 lights blue. When a USB cable is connected to this mini-USB connector, two
COM ports are enabled in Windows. The main 8-wire UART interface of the cellular module is
available over the first COM port opened by the driver after the end of the module boot, once
the switch-on of the cellular module is triggered (see point 11 ).
b. Connect an RS232 cable to the DB9 connector ( Cellular RS232 Main UART , J500 on EVB):
the main 8-wire UART interface of the cellular module is available over RS232 after the end
of the module boot, once the switch-on of the cellular module is triggered (see point 11 ).
c. Connect a USB cable to the mini-USB connector ( Cellular USB two UARTs , J201 on ADP-R6
/ ADP-L6). The LED DS201 lights blue. The two 4-wire UART interfaces of the cellular module
are respectively available over the two numbered COM ports opened by the driver after the
end of the module boot, once the switch-on of the module is triggered (see point 11). (To
enable two UART interfaces, see the AT commands manual [1] , the +USIO AT command.)

Table 7: UART serial interfaces configuration
Run an AT terminal application (e.g., the u-blox m-center tool) selecting an AT port, with these
settings:
▪
Data rate: 115,200 bit/s
▪
Data bits: 8
▪
Parity: N
▪
Stop bits: 1
▪
Flow control: HW
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).
11. Press the Cellular power-on button (SW302 on the EVB) to switch on the cellular module
mounted on the APD-R6.
