This document is intended to provide guidance when adding a modem from the
ZETA-xxP series to your system.
The ZETA-xxP series of LTE Cat 1/LTE Cat 4/LTE Cat M/LTE Cat NB IoT/GSM
Ultra Low Power modems are an advanced range of high performance modems
developed for easy integration into existing systems and for embedded application
development.
The ZETA-xxP modem range is based on the Telit xE910 GPRS/UMTS/LTE
module series and is designed to be ultra low power for use in power sensitive
applications. The modem manages the module power up sequence and can be
programmed to perform additional custom tasks. In addition to offering 2G/GSM
fallback the modem also provides access to the new LTE Cat M1 and LTE Cat NB
IoT networks for full future compatibility.
The modem family is also available with current LTE Cat 1 and LTE Cat 4 variants
for high speed applications.
This document discusses the modems states and modes of operation in addition
to the electrical characteristics of the modems interfaces.

The ZETA-xxP range of LTE Cat 1/LTE Cat 4/LTE Cat M/LTE Cat NB IoT/GSM Ultra
Low Power modems are amongst the most versatile modem series available today.
The ZETA-xxP series offers a range of interface options including USB and RS232
serial port communication, for connection to existing legacy equipment and high
speed USB interfaces.
The ZETA-xxP has been designed from the ground up to be very power efcient and
incorporates some unique features to allow it to run in an ultra low power state when
utilizing the standard AT+CFUN=5 low power mode.
The Siretta ZETA-xxP contains a powerful C development environment which reduces
redundancy and optimizes the architecture of your solution and lowers system
component costs. In a typical integration project, IoT device developers employ a
microcontroller to manage the modem functionality and other device peripherals. The
Siretta ZETA-xxP integrates Telit IoT AppZone which eliminates the requirement for an
external controller, reducing cost and complexity, embedding application code right in
the module.
The Siretta ZETA-xxP Includes a comprehensive set of high-level enabling functions
allowing you to focus on the market-differentiating value-added features of your
application software. Reduces time to market and project costs; and when you
complete your development, reuse it across different products and technologies to
expand your markets and opportunities.
Create a proof of concept in record time and with minimal investment. Leverage
robust building blocks to shorten your development cycles through to mass
deployment.

AT Commands
The ZETA-xxP range of wireless modems has a cellular engine at its heart which can
be controlled via the serial interface using standard AT commands.
The AT command is an ATTENTION command and is used as a prex to other
parameters in a formatted string. The AT command combined with other parameters
can be sent to the modem with your preferred terminal emulator package (TMSTerm/
TeraTerm/HyperTerminal) and typed in manually as a command line instruction.
The wireless module is compliant with the following AT command formats:
1) Hayes standard AT command set, in order to maintain the compatibility with
existing SW programs.
2) 3GPP 27.007 specic AT command and GPRS specic commands.
3) 3GPP 27.005 specic AT commands for SMS (Short Message Service) and CBS
(Cell Broadcast Service)
4) FAX Class 1 compatible commands
5) Proprietary command set, the module family also supports a proprietary set of AT
commands for special purposes outside of the standard AT specication.
To obtain the latest AT command reference guide* with a full list of supported AT
commands, please contact your Siretta representative or alternatively visit:
www.siretta.com
NOTE - This following document refers to useful AT commands throughout and offers
descriptions of how to use the AT commands with the ZETA-xxP wireless modems.
*For all LTE modems refer to the latest LTE AT Command Manual.

Download Latest Edition
This ZETA-xxP can be used in a number of applications, some examples are
shown below:
»Low power cellular communication interface
»Upgrade your estate with a low power solution which continues to operate on the
existing 2G/GSM network
»Future proof your applications today by installing a 4G/LTE compatible solution
which operates with 2G/GSM fall back
»Standard RS232 modem attached to existing equipment (PC/MAC/Linux)
Typically connected devices are:
»PC/MAC/Linux platforms for use as a dial-up modem
»Embedded (connected directly to remote equipment without a PC attached)
Operating System Connected Modem
»Internet enable a remote device with RS232 connectivity over 2G/GPRS, 3G/
UMTS, LTE Cat M, LTE Cat NBIoT, LTE Cat 1, LTE Cat 4. Internet connectivity
can be retrotted to end equipment without changing the software or
conguration of the remote device.
»Used in countries or places where broadband and WiFi is a less common method
to connect to the internet or where services are unavailable. The ZETA-xxP
modem can overcome this restriction by providing a mobile internet solution over
the LTE/4G network.
Examples:
»Vending machine where the head ofce would poll for drinks remaining/money
taken etc. This would be an on-demand pull to obtain results in real time.
»Monitoring AMR/temperature/equipment in a home, i.e. Interrogate lights etc.
»Remote entry system, i.e. Send a message to the modem to open a gate/door to
allow access.
»Streaming live data from remote system to a central location
»Remote printing applications (remotely print over the GPRS network)
»Polling remote devices for information to prevent an engineer callout
System Overview
USB Interface
This is a USB standard Communication Device Class (CDC) device. A device driver
is available for Windows OS. Linux uses standard CDC ACM drivers. Please contact

LED Indicators
There are 3 LED outputs on the ZETA-xxP modem coloured Red, Green and Blue.
By default, these show the functional/operational state of the modem. However,
these may also be congured using software control by the user for other indication
purposes. Table 4 describes the functions of the LEDs.

Blue Rapid blink during power off, otherwise off Off / User dened
On initial application of power, all LEDs will briey illuminate. During power up, the
green and blue LEDs are controlled directly by the ZETA-xxP power management
controller, and the red LED is controlled by the embedded modem module. While
the ZETA-xxP is in the power up state the green LED will ash rapidly (500mS on,
500mS off) and the Blue LED will be off until the power up process is complete.
ZETA-NLP Variants
After the power on process has completed, red, green and blue LED’s are disabled
completely to save power whilst it is in an operating state. The green LED will
briey ash once every 30 seconds to indicate that the modem is in the on.
ZETA-NSP, ZETA-NEP and ZETA-GEP Variants
After the power on process has completed, red, green and blue LED’s are
controlled directly by the module using the standard set of AT commands seen on
page 17.
