Introduction
The M2M Control CX320 is a powerful successor to the M2M Control C360 with significant
improvements in features, capacity, power, and security. The M2M Control CX320 is based on the
latest NX hardware architecture, offering an unprecedented balance between price and performance.
The M2M Control CX320 is positioned for a broad range of professional industrial Internet of Things
applications. With onboard M-Bus / Wireless M-Bus and pulse counting inputs (S0), it is a perfect
component in advanced Energy Manage ent applications.
The device rests on the NX32L (NX 2 for Linux) architecture that embraces many new technologies
and at the same time maintains full backward compatibility, which ensures already implemented and
tested NX32 applications can execute without changes.
The M2M Control CX320 device has been designed to meet the ever-increasing security challenges. It
offers full TLS on all major protocols and includes a hardened protected execution environment with
dual-boot and automatic fallback and recovery.
The M2M Control CX320 can also operate as a secure and intelligent industrial router/firewall for
LAN side clients connecting to the Internet over the cellular interface.
This manual contains technical documentation covering the installation and usage of the M2M
Control CX320 device. For detailed information on the product's programming and software
configuration, please refer to the M2M Control IDE documentation.
In our documentation the term “RTCU” stands for Remote Terminal Control Unit and constitutes a
unique combination of a programmable control-unit with the possibility of both digital- and analog
I/O plus a GSM / 2G / G / 4G communication,

Mini USB-B Connector
This USB port is for programming and communication with the M2M Control IDE or other RACP
compliant applications. A standard USB cable can be used between the device and the PC.
Ethernet / LAN
This is a standard 10Base-T/100Base-TX IEEE 802. compliant RJ45 Ethernet connector.
Please use an appropriate connector and cable, such as a standard CAT-5 twisted pair patch cable
The connector has the following LED indicators that show the LINK status and communication
activity.
Power Supply
The M2M Control CX 20 device must be supplied with 8.. 6 VDC from an external DC power source.
Positive power is applied to the SUPP pin and the ground to the PGND pin.
There are three different ground labels for ground connections: Supply ground (PGND), signal
ground (SGND), and analog ground (AGND).
The signal and the analog grounds are filtered from the power ground. Power ground must only be
used as a power supply return path.
The M2M Control CX 20 is protected against wrong polarity. If a chassis or system ground is
connected to either SGND or AGND, a wrong polarity on the supply lines will destroy the internal
GND connection.
The M2M Control CX 20 contains an internal backup battery, which will supply the device if the
external power supply fails or is disconnected. By default, the CX 20 is powered down when a power
failure occurs. This setting, however, can be changed. Please consult the M2M Control IDE online
help for more information. When the wakeup/ignition inputs are activated with a logical high, the
M2M Control CX 20 device will wake up from a power-down mode.

Digital outputs
The digital outputs control eight "high-side" switches. They function like contacts, where one side is
connected to the positive supply of the CX 20 unit, and the other side is to the output. The switches
are protected against short circuits, ESD, and electronic kickback from inductive loads such as a relay.
The maximum switchable inductance is 20mH and must not be exceeded.
The digital output control circuit is supplied from the power supply connected to the DOUT SUPP
and DOUT GND. The DOUT GND is connected with the system GND internally
The CX 20 unit offers advanced power management that can enable one or more outputs while the
device is in low power mode. Please consult the M2M Control IDE documentation for additional
information.

Digital Inputs / S0 inputs / Ignition Input
The digital inputs are all low-pass filtered and transient protected. To activate the inputs, connect a
positive voltage between the input and the SGND connector.
Digital inputs 1-4 can be configured individually as S0 input (IEC62053-31, Class A).
By default, the digital inputs are configured as normal inputs. For placement and configuration og the
hardware jumpers inside the unit, please refer to the configuration guide in Appendix A.
Please note: The DIN 5/IGN input is unique as it also functions as the ignition input. If the ignition
input is activated with a logically high or low (Wait For Event mode only), it will wake up the unit
when the device is in low power mode. A power apply will also wake up the unit, if it is in power-
down mode or WaitForEvent mode with power apply and/or ignition selected for wakeup.
Please note: Digital inputs 6-8 do not work as high-speed IO, so PCT is limited to 400Hz, and
incremental encoders are not supported.
The power management allows the possibility to configure a wakeup on one or more digital inputs
with individually configured falling- or rising edge detection. Please consult the M2M Control IDE
documentation for additional information.
S0 co pliant inputs (IEC62053-31, Class A co patible)
In S0 configuration, the relevant M2M Control CX 20 input will act as a 'pulse input device,' where a
current source is provided on the input connector so that a simple switch between the SGND and the
appropriate input will activate it. This is used in most electricity metering equipment.
S0 must be enabled from the application to work as an S0 compliant input.
Please notice: The M2M Control CX 20 unit must be supplied with a minimum of 16 VDC to fully
comply with the S0 standard. The inputs will still work when supplied with 12VDC but will not be in
compliance with the S0 standard.

Analog Inputs
The M2M Control CX 20 has four analog inputs, which can be configured individually to work either
as voltage or current measurement inputs using the configuration jumpers. The range in voltage
mode is 0..10 VDC, and in current mode 0..20mA.
The conversion resolution is 12 bit.
The input signal is connected between AINx and AGND. Therefore, AGND must be connected to the
reference of the connected equipment. Please be aware that deviations may occur, as the system is
very noise-sensitive. Avoid long unshielded wires and significant fast-changing signals routed
parallel to the analog signals.
The inputs are low-pass filtered, ESD- and transient protected.
By default, the inputs are configured as voltage inputs. For replacement and configuration of the
hardware jumpers inside the device, please refer to the device configuration guide in Appendix D.
