Introduction
This manual contains technical documentation which allows for easy installation and use of the
M2M Control C660 unit. For information on the programming and software configuration of the
M2M Control C660 please refer to the M2M CONTROL IDE documentation.
The M2M Control C660 adds a new chapter to the highly successful era of the C6xx series offering
a wide range of new features and performance improvements while still resting on the proven
track record and confidence of the M2M Control C600 series.
The M2M Control C660 uses the next generation NX32 execution model, and is fully backward
compatible with the X32 execution model of the former C6xx series. Existing software will
therefore be able to operate without any changes or costly re-testing. Mechanically and electrically
the C660 is fully back-ward compatible with the C600 and constitutes therefore a direct plug-in
replacement.
The M2M Control C660 has been designed from the ground up for professional telemetry /
telematics applications and has been designed according to the highest technical standards for
professional automotive and industrial use. The product has all necessary regulatory approvals –
including 2004/104/EC / UN ECE R10 –edition 3 and CE mark.
The advanced power-management features on the M2M Control C660 combined with the on-
board high-capacity Li-Ion battery allows the unit to stay in power-saving mode for a longer
period of time still being connected to the GSM network and capable of waking up on for example
GSM activity, change of digital inputs or a vibration sensor.
For demanding applications the M2M Control C660 offers a 4G LTE Cat.1 cellular communication
with fallback to 3G and 2G. The positioning is enhanced with a state-of-the-art GNSS receiver with
GPS and GLONASS support.
The M2M Control C660 rests on the M2M CONTROL Professional Series RTCU Platform which
brings all the necessary tools together to develop, implement and maintain today’s sophisticated
M2M/IoT applications.
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
modem.
The development task is supported by the M2M CONTROL IDE development environment,
complimented by a large and comprehensive documentation and application example library.

M2M CONTROL C660 - Technical Manual V2.00
www.m2mcontrol.de
Power supply
The M2M Control C660 device must be supplied with 8..36 VDC from an external DC power
source connected to the X1 connector. Positive power is applied to the SUPP pin, and ground is
connected to the PGND pin.
The connector has two “SUPP” supply pins as these also supplies power to the digital outputs. If
the total current consumption on the digital outputs exceeds 5A, then power must be applied to
both pins. Otherwise one pin is sufficient.
There are three different labels for the ground connections:
Power Ground (PGND)
Signal Ground (SGND)
Analog Ground (AGND)
The signal and analog grounds are filtered from the power ground. Power ground must only be
used as power supply return path. The signal ground is used as ground reference for digital I/O’s
and serial interfaces, and the analog ground is used as a low noise analog ground reference for the
analog inputs.
The C660 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.
For avoidance of such a scenario, a fuse can be installed on the positive supply.
The C660 also contains an internal high capacity backup battery which will supply the C660 if the
external power supply fails or is disconnected. By default the C660 is powered down when a
power fail occurs. This setting, however, can be changed. Please consult the M2M CONTROL IDE
on-line help for more information. The display will automatically turn off when external power is
removed.
Disabling the external DC power from the application interface and forcing the device to operate
on the internal backup battery is supported. Please consult the M2M CONTROL IDE
documentation for additional information.
When the ignition input is activated with a logical high, the C660 unit will wake-up if it was in
power down mode. The ignition input (digital input 5) is available on the power connector to
minimize the need for connectors in minimal installations, but it is also available on the X3
connector (digital I/O and analog Inputs) - only one should be used at a time.

Digital Outputs
The digital outputs control eight “high-side” switches. They function like a contact, where one side
is connected to the positive supply of the C660 unit and the other is the output. The switches are
protected against short circuit, ESD and electronic kickback from inductive loads such as relays etc.
The maximum switchable inductance is 20mH and must not be exceeded.
The digital outputs are supplied through the X1 power connector that also supplies the rest of the
C660 unit. As the power is also the M2M Control C660 main power, a power-fail would also affect
the digital outputs.
The C660 unit offers very advanced power management which makes it possible to have one or
more outputs enabled while the C660 is in low-power mode. Please consult the M2M CONTROL
IDE on-line help for more information.

Please note: Special attention to wiring must be taken; if the total current consumption of the
digital outputs exceeds 1.5A, then PGND must be used as return path for the output(s).
If the total current consumption of the digital outputs exceeds 5A, the two SUPP pins must be used
for supply.
M2M CONTROL C660 - Technical Manual V2.00
www.m2mcontrol.de
Digital 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 GND connector.
Please note: The DIN 5/IGN input is a special input as it also functions as the ignition input. If the
ignition input is activated with a logical high or low (Wait For Event mode only), when the C660 is
in low power mode, it will wake-up the unit. 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 wake-
up. The ignition is de-bounced with a period between 1-2 ms, when used as a digital input. So any
logical level applied to this input must be greater than 2 ms to be valid. The DIN 5/IGN input is
available on both the X1 power connector and the X3 connector together with the other digital
inputs –only one should be used at a time.
The power management allows the possibility to configure a wake-up on one or more digital
inputs with individually configured falling- or rising edge detection. Please consult the M2M
CONTROL IDE documentation for additional information.

Analog Inputs
There are two analog inputs available on the unit.
The analog inputs are voltage inputs specified with an operating range of 0V to 10V DC. The
conversion resolution is 12 bit +/- 1.5% FSR @ 25 degrees ˚C.
By default the analog voltage is converted to a digital value with a resolution of 10-bit before being
presented to the application (0..1023). The application can change the resolution to the full 12 bit
(0..4095). Please consult the M2M CONTROL IDE documentation for further details.
The input signal is connected between AINx and AGND. 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 high current, fast changing signals routed
parallel to the analog signals.
The inputs are low-pass filtered, ESD- and transient protected.

RS485
RS485 is available on the X2 connector as serial port 1. The RS485 bus a multi-drop network with a
maximum of 32 units connected simultaneously to the bus. The RS485 bus contains an RS485+
(non-inverting) and an RS485- (inverting) signal as well as a signal ground which must always be
connected to the common signal ground for all units connected to the RS485 bus!
The maximum cable length for the RS485 bus is according to EIA/TIA-485-A standard (max. 1200m
@ <100kbit); this limit is highly influenced by the quality of the cable, signaling rate, noise etc.
At longer cable lengths, noisy environments or high communication speed it might be necessary to
terminate the transmission line with a 120
1
ohm resistor between terminal RS485+ and terminal
RS485- at each end of the wires to avoid signal reflections etc.

CAN
The M2M Control C660 provides the physical layer for the CAN (Controller Area Network) serial
communication interface in accordance with the ISO 11898 standard. The CAN bus is designed for
high-speed (up to 1Mbit) robust communication in especially harsh environments like those found
in the automotive industry.
The CAN interface can be connected to an existing CAN network with a common protocol like the
J1939 standard, to retrieve information for surveillance or information purposes. The interface can
also be used as a robust serial data link with a non-standard protocol. Please consult the M2M
CONTROL IDE documentation for more information.
The physical layer consists of a two wire (CAN-H and CAN-L) differential bus and a signal
ground for reference.
If the C660 is connected to a “non-existing” network, a 120
1
ohm resistor must be connected
between CAN-H and CAN-L on each end of the transmission line in order to terminate it and
avoid signal reflections.
Be aware that connecting the C660 to a CAN network can be dangerous. If the C660 is not
configured with the correct network parameters, it will lead to network corruption and may
interfere with other connected equipment on the bus. Especially in vehicles great precautions must
be observed to prevent communication interruptions.
By default unit writing capability on the CAN bus is disabled and may be enabled by installing
hardware jumper JP901
2
inside the unit.
A wide range of software functions is available for easy access to the network. Please consult the
M2M CONTROL IDE documentation for further information.

1-Wire bus
The 1-Wire bus is available on the X2 connector. All 1-Wire communication goes through a single
connection, and all 1-Wire devices connected to this connection retrieves its power directly from
the bus (called parasitic power). For this only two wires are needed –the 1-wire signal and the
ground reference –allowing minimal cable installations.
For 1-Wire ID-Button readers, which include a built-in LED, a dedicated output is available for this
purpose. Please consult the M2M CONTROL IDE documentation for further information.

Hands-free connector
The C660 unit has a 4-pole 2.5mm jack connector for connecting a hands-free set to the built-in
GSM modem. The speaker output is amplified through the internal Class-D amplifier and is a
differential (balanced) signal. A loudspeaker of 4/8 Ω can be connected directly to the speaker
output. The microphone input is differential in order to minimize GSM (TDMA) noise. An audio
line transformer must be used to convert the signal to a single ended signal, when connected to
external equipment that does not have a differential (balanced) input. Otherwise the GSM noise
will not be suppressed / cancelled, and will pass through all the way to the loudspeaker.
The microphone signal is biased internal for active microphones.

3D movement sensor
The M2M Control C660 unit contains a 3-axis accelerometer in order to detect both vibration and
motion. It makes it possible to detect movement and position change in 3 directions, X-Y-Z with a
force as high as 16g. The simplest use is with the power management detecting when the vehicle is
moved, and the most advanced analytical applications such as driving behavior / eco driving.
Please consult the M2M CONTROL IDE documentation for more detailed information.
The positions of the 3-axis is as following:
