Introduction
This manual contains technical documentation allowing easy installation and use of the
C350 pro product. For information on the programming and software configuration of the
C350 pro please refer to the M2M Control IDE documentation.
The C350 pro has been designed ground up for professional wireless industrial
applications with its strong on-board I/O capabilities and multiple communication interfaces
such as: CAN bus, 1-Wire, USB, RS232 and dual RS485 channels. The on-board I/O
system can be expanded almost indefinitely and completely transparent by adding external
MODBUS compatible I/O modules! This unique I/O expansion capability, combined with
the possibility to operate as a MODBUS master and slave simultaneously, positions the
C350 Pro as the perfect product for SCADA-like applications.
The C350 pro offers many other sophisticated features such as: A 512kbyte internal flash
drive and a SD-CARD reader with a FAT32 compatible file-system for easy sharing of files
locally and remotely with a PC/Server.
There is optional support for Bluetooth, Ethernet, Wi-Fi, Camera module and a Mobile
Data Terminal for user interaction.
The advanced power-management features on the C350 pro 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 and many other events.
These features open up for the use of the C350 pro in exciting new application areas
where extremely low power consumption and flexible wake-up conditions are a crucial
parameter for successful product integration.
The C350 pro is also available with additional 8Mbyte persistent onboard memory.
Attention: the use of GSM and GPRS services can generate cost. Take care that the tariff
of the used SIM card is suitable for your application. We highly recommend not using SIM
cards where GPRS services are charged by elapsed time.

Power supply
The C350 pro unit can be supplied with 8..36VDC from an external DC power source.
Positive power is applied to the SUPP pin and ground is connected to the PGND pin.
There are two SUPP pins as these also supplies the digital outputs. If the total current
consumption on the digital outputs exceeds 1A refer to digital output section for special
attention on the wiring. Otherwise one pin would be sufficient.
There are three different ground labels: Power Ground (PGND), Signal Ground (SGND)
and 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 C350 pro is protected against wrong polarity. If a chassis or system grounds are
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 C350 pro also contains an internal high capacity backup battery, which will supply the
unit if the external power supply should fail or be disconnected. By default the C350 is
powered down when a power fail occur. This setting however can be changed. Please
consult theM2M Control IDE on-line help for more information. The display will
automatically turn off when external power is removed.
When the wakeup/ignition input is activated with a logical high, the C350 pro unit will wake
up if it was in power down mode.
Please Note:
•Minimum 12VDC supply is necessary for 0-10V analog output configuration.
•Minimum 16VDC supply is necessary for digital inputs 1-4 to work as S0 compliant
inputs.

Digital I/O
The C350 pro unit has eight digital inputs and eight digital outputs. Digital input 1-5 has
several operation modes. Please refer to the digital input section for additional information.
The digital outputs are integrated high performance “high-side” switches.
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 C350 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 directly from the SUPP power pins, which also supplies
the rest of the C350 unit. As the power is also the C350 pro main power, a power-fail
would also affect the digital outputs.
The C350 pro unit offers a very advanced power management, which makes it possible to
have one or more outputs enabled while the unit 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 1A then PGND must be used as return path for the output(s).
If the total current consumption of the digital outputs exceeds 5A two SUPP and PGND
pins must be used for supply.

Digital inputs / S0 inputs / wakeup (ignition) input
The eight digital inputs are all low-pass filtered and transient protected. To activate the
inputs, connect a positive voltage between the corresponding input (DINx) and SGND.
Digital input 1-4 can individually be configured as S0 input (IEC62053-31, Class B) and
DIN5 can work as wakeup (ignition) input.
As default the digital inputs are configured as normal inputs. For placement and
configuration of the hardware jumpers inside the unit, please refer to the configuration
guide in Appendix A.
S0 compliant inputs (IEC62053-31, Class B compatible)
In S0 configuration the relevant C350 pro input will act as ‘pulse input device’ and a
current is supplied into the input connector, so that a simple switch between SGND and
the appropriate input will activate it. This is used in most electricity metering equipment.
Please Note: The C350 pro unit must be supplied with minimum 16VDC. And S0 must be
enabled from the application in order to work as S0 compliant input.

Wakeup (ignition) input
The DIN5 / Wakeup (ignition) input is a special input as it also functions as the wakeup
input. If the input is activated with a logical high or low (Wait For Event mode only) when
the C350 pro is in low power mode it will wakeup the unit. A power apply will also wake the
unit up if it is in power-down mode or in Wait For Event mode with power Apply and/or
ignition selected for wakeup. The input 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 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 on-line help for more information.

RS232 communication ports (EIA/TIA-232 and V.28/V.24 compatible)
Two general purpose RS232 ports available on the C350 pro unit both are compliant with
the EIA/TIA-232 standard. Serial port 1 cannot use handshaking, but on serial port 2 all
control signals are present.
Serial port 1 / programming port.
This port can be used as general-purpose RS232 serial port or as a C350 pro
programming port. In order to use the port for programming, the RS-DET pin must be
connected to SGND. When using the port as general-purpose RS232, the RS-DET pin
must be left unconnected. Further details on the programming cable are available in the
M2M Control IDE online help.

Serial port 2
The serial port 2 is a general-purpose RS232 port with all control signals according to EIA-
561 that defines RS232 on a modular connector.
The signals are available on the RJ-45 connector located on the bottom side of the C350
pro unit.
Serial port 2 can also be allowed to hand over functionality to the internal GSM module to
work as GSM modem. Using this mode will effectively 'hand over' the GSM module inside
the C350 pro unit, so that it is exclusively controlled by any external device connected to
serial port 2 on the unit. Please consult the M2M Control IDE on-line help for further
information.

RS485 communication ports (EIA/TIA-485-A compatible)
RS485 is a multi-drop network with a maximum of 32 units connected simultaneously to
the bus. The RS485 bus contains a RS485+ (non-inverting) and a 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 1201ohm resistor at each end of the
transmission line to terminate it and avoid signal reflections. If the C350 pro is use as
endpoint unit the hardware jumper JP7 (standard port) / JP12 (optional port) can be
installed to terminate the RS485 communication lines with 120 ohm.
Both the standard and the optional RS485 port can be used as general-purpose RS485
serial port or as IO extension module(s) port. When used with supported MODBUS IO
extension modules, general purpose use is disabled. The RS485 port signals are available
on the pluggable screw terminals.
Further details on the MODBUS IO extension modules and use are available in the M2M
Control IDE on-line help.
By default the RS485 communication lines are not terminated with 120 ohm. For
placement and configuration of the hardware jumpers inside the unit, please refer to the
configuration guide in Appendix A.

RS485 (optional)
If the optional RS485 port is installed and enabled, RS485 will be available on the
pluggable screw terminals. Internally this RS485 port and the programming port share the
same signals and RS485 will be disabled if a programming cable is inserted or RS-DET is
low.

CAN communication port
The C350 pro 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 either be connected to an existing CAN network with a common
protocol like the J1939 standard to retrieve information for surveillance or information
purposes. Or the interface can be used as a robust serial data link with a non-standard
protocol. Please consult the M2M Control IDE on-line help for more information.
The physical layer consists of a two wire (CAN-H and CAN-L) differential bus and a signal
ground for reference. These signals are available on the pluggable screw terminals.
Be aware that connecting the unit to a CAN network can be dangerous. If the unit 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 interruption of the communication.
On the C350 pro unit writing capability on the CAN bus is enabled by default, this can be
disabled by installing the hardware jumper JP5 inside the unit.
If the C350 unit is connected to a “non-existing” network, a 1202ohm resistor must be
connected between CAN-H and CAN-L at each end of the transmission-line to terminate it
and avoid signal reflections. This resistor can be connected by installing the hardware
jumper JP15 inside the unit.
By default the CAN communication lines are not terminated with 120 ohm and writing
capability on the CAN bus is enabled. For placement and configuration of the hardware
jumpers inside the unit, please refer to the configuration guide in Appendix A.
A wide range of software functions is available for easy access to the network. Please
consult the M2M Control IDE on-line help for further information.
