3 POWER SUPPLY
The EVB power can be provided by USB hosts or an external 5V supply which is then converted by
LDOs to create the 3.3V and 1.8V needed for the onboard circuits. There is no switch needed for
selecting a particular supply. Instead, diodes are installed to provide reverse current protection for
each individual supply. Jumpers CN11 may be used to measure the current consumption of the
module as described in Section 9. A block diagram of the power supply connections is shown below.
Figure 5 Power supply block diagram
3.1 USB power supply
In the default configuration, the EVB is connected to a PC through at least one of the two mini-USB
ports CN13 and CN14. These connections provide the USB-UART serial interfaces and serve as the
power sources for the EVB. The mini-USB connector locations are as shown below in Figure 6.
Figure 6 USB connectors location

Type 1SC EVK User Guide, v1.3, 5/4/2020 Page 10 of 44 www.murata.com
3.2 External 5V supply
The EVB can also be powered by applying 5V to the Ext_Vin pin of the Arduino interface. This is pin
8 on the CN3 header which is located on the bottom side of the EVB as shown in Figure 7.
Figure 7 Ext_Vin pin location on bottom side of EVB
4 SERIAL INTERFACES
The EVB exports 3 module UART ports through either the USB-UART mini-USB connectors or the
Arduino header. A block diagram for this is shown in Figure 8.
Figure 8 Exported UART interfaces
In the default configuration, USB ports CN13 (UART A & C) and CN14 (UART B) are connected to a
PC for application testing and development; the Arduino interface is not used.
The host control for the modem is accomplished through the UART B (CN14) interface. There are
two possible options:
•Use a PC application (e.g., PuTTY): connect a mini-USB cable to CN14 and disconnect the
Arduino interface. See Section 0 for more instructions.
•Use the Arduino interface (e.g., Nucleo 64 board): connect MCU to the Arduino interface and
disconnect the mini-USB cable from CN14. See Section 6.1 for the detailed Arduino interface
pin assignments.
UART A & C (CN13) are used for CLI and debugging. See Sections 7.4 for more details.

7 STARTUP PROCEDURE
Unpack the EVK package and use the following steps to setup the reference PC environment and
configure the EVK. The ensuing discussions are based on a PC running Windows 10 Pro.
Do not connect to the Arduino interface.
7.1 Install PuTTY
Download and install PuTTY for Windows from https://www.putty.org. This is the recommended
serial port console for PC serial communication with the module.
7.2 Connection to PC
Connect two USB cables from a PC to the two mini-USB ports labeled CN13 and CN14. The driver
should be automatically installed for the two UART ports (A & C) associated with CN13.
Figure 11 EVK setup
The driver for UART B associated with CN14 needs to be installed manually.
•Open the following web page: https://www.silabs.com/products/development-
tools/software/usb-to-uart-bridge-vcp-drivers.
•Download the latest version of universal driver for Windows 10.
•Unzip the downloaded zip file, and run CP210xVCPInstaller_x64.exe to install the driver.
After the above steps, there should be three COM ports shown in Device Manager -- one for Debug
(e.g. COM8, 921600 baud), one for CLI (e.g. COM9, 115200 baud), and one for AT (COM13, 115200
baud). See below an example screenshot of the Device Manager.

Type 1SC EVK User Guide, v1.3, 5/4/2020 Page 16 of 44 www.murata.com
Figure 12 COM ports assignment shown in Device Manger
7.3 AT/PPP port
By default, UART B is the dedicated AT/PPP port. Start a PuTTY session and connect to the AT port.
The baud and flow control of PuTTY session, respectively, need to be set to 115200 8N1 and
“None”.
If the driver is installed properly but there is no response from the module, use the CLI port to ensure
that the modem is not in the u-boot mode (See Section 7.4 for details).

Type 1SC EVK User Guide, v1.3, 5/4/2020 Page 17 of 44 www.murata.com
7.3.1 AT commands
The module supports a subset of standard 3GPP AT commands and a set of proprietary commands.
•Standard AT commands start with “AT+”,
•Proprietary AT commands start with “AT%”.
All commands are case insensitive.
Here is a list of some useful AT commands.
-at%ver to list versions
-at+cgmi to read name of manufacturer
-at+cgmm to read model number
-at+cgsn to read IMEI number
-at+cgmr to read software version
-at%ccid to check SIM card status
7.3.2 From AT Channel to PPP Channel
The user can switch between an AT channel to a PPP channel as follows. See Section 8 for the
details to create the PPP interface with a PC.
1. Connect a mini-USB cable to the CN14 (UART B) port.
2. Open a terminal shell to the AT channel COM port (the default functionality of UART B is AT
channel).
3. In order to switch to the PPP channel functionality, the user needs to run the ‘ATD*99’ AT
command.
4. After step #3, the AT channel will switch to a PPP channel, on which the user can establish a
PPP connection.
5. In order to switch back to AT channel functionality, the user needs to follow the steps below (in
the PPP terminal):
a. Enter the ‘+++’ command without pressing the ‘Enter’ key.
b. Wait for one second (at least).
c. Press the ‘Enter’ key.
6. After step #5, the terminal will suspend the PPP and switch back to an AT channel terminal.
7. Now the port accepts regular AT commands; ATO and AT%H0, respectively, can be used to
resume and terminate the PPP session.
7.4 CLI port
The CLI port is intended for testing purposes and allows the user to enter commands to interact with
the module.
Open PuTTY to the CLI port. The following screenshot shows how to save the configuration as
“COM9” for later use.

Type 1SC EVK User Guide, v1.3, 5/4/2020 Page 18 of 44 www.murata.com
Figure 14 PuTTY configuration for CLI port
After connecting to the CLI port, check the prompt. If the prompt is “#”, that means the
firmware is in u-boot mode. Enter “boot” command to boot it up; after boot up, the prompt
should change to “>”. This is illustrated below.
Figure 15 Prompt for CLI Port
7.4.1 CLI commands
All supported CLI commands can be seen with the “help” command. The “help” command lists
categories of CLI commands. Use “help <category>” to see commands under a particular category.

Type 1SC EVK User Guide, v1.3, 5/4/2020 Page 19 of 44 www.murata.com
Figure 16 CLI Commands
Here is a list of example CLI commands.
-ver to show the current version of the firmware installed
-ifconfig to show the interfaces
-ping 127.0.0.1 to ping an IP address
7.4.2 Sending AT commands from CLI channel
The CLI channel supports sending AT commands to the modem, as follows:
at <AT command>
For example:
-at at+cfun?
-at at%ccid
7.4.3 From CLI Channel to AT Channel
The user can switch a CLI channel to an AT channel as follows:
1. Connect a UART serial cable to the device’s CN13 (UART A & C) mini-USB connector.
2. Open a terminal shell to the CLI COM port (the default functionality of UART A is CLI).
3. To switch to the AT channel functionality, run the ‘serialSwitch’ CLI command.
4. After step #3, the terminal will switch to an AT channel terminal and the user can run normal
AT commands in it –there is no need for the extra “AT” as in the case with the CLI port.
5. To switch back to CLI functionality, run the ‘at%cli’ AT command.
6. After step #5, the terminal will switch back to a CLI terminal.
