Table 7: Serial interface configuration

Run an AT terminal application (e.g. the u-blox m-center tool), and select the AT COM port with

the following settings:

o

Data rate: 115,200 bit/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.

To access the cellular module via USB interface, connect a USB cable to the Cellular native USB

connector on the ADP-R4. The related LED DS100 lights blue.

After the end of modules’ boot (refer to point 9 for the procedure to switch-on the cellular

module), the ports listed in Table 8 are enabled by the Windows USB driver (details as the

numbering of the ports can be seen via the Windows Device Manager):
