1.3 Product Overview
The Skywire™ Development Kit includes one Skywire™ cellular modem, baseboard, antenna,
power supply, and debug cables. The kit enables you to develop your application directly on the
Skywire™ modem with three different ways to connect:
Connect your PC to the x910 modem UART port via onboard USB-to-UART converter
and send AT commands directly to the modem through PC terminal applications.
The baseboard is an Arduino shield, so you can plug the module directly onto an Arduino
microcontroller. (Kit includes sample sketches showing how to initialize the modem, make
data connections, and send and receive SMS messages.)
To connect the kit to a different processor or development kit, a 14-pin header breaks out
the necessary signals for easy connection to any device. The modem supports I/O levels
from 1.65-5.5V, simplifying connection to other systems.

2. Connect to Kit using a PC
This section covers how to connect your development kit to a PC and
provision the modem with your cellular plan. It also covers how to
communicate over the serial port to the Telit x910 modem which only
requires the use of USB port and connector marked J14 or USB2 in the
diagram below. USB1 (connector J5) is used for Telit firmware updates to
the modem and is not used in this section.

AT+CREG?
followed by the Enter key, and the terminal should respond with:
+CREG: 0,1 or +CREG: 0,5

you would like to activate. A NimbeLink staff member will call
you to activate the modules real-time.
2.11 Send Modem Activation String
In the terminal program, type the letters:
ATD*22899;
followed by the Enter key, and the module will begin the activation process
which can take several minutes. The terminal should respond with:
OK
#OTASP: 0
#OTASP: 1
#OTASP: 2
NO CARRIER
For all other responses, review network status responses online.
Reset power, and repeat steps 2.4 through 2.9 before moving
on to step 2.12.
