DIN Rail Mounting
The M2M Control CX530 can be delivered in a version suitable for mounting on a standard DIN
rail according to IEC/EN 60715.
On the bottom side of the device the DIN rail clip allows attaching to the DIN rail.
Power Supply
The M2M Control CX530 device must be supplied with 8..36 VDC from an e ternal DC power
source. Positive power is applied to the XPWR pin, and the ground to the XGND pin.
There are three different ground labels for ground connections: Supply ground (XGND), signal
ground (GND), 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 CX530 contains an internal backup battery, which will supply the device if the
e ternal power supply fails or is disconnected. By default, the CX530 is powered down when a
power failure occurs. This setting, however, can be changed. Please consult the M2M CONTROL
IDE on-line help for more information. When the wakeup/ignition inputs are activated with a
logical high, the M2M Control CX530 device will wake up in power-down mode.

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 1/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 CX530 is in low power mode. A power apply will also wakeup the unit, if it is in power-
down mode or WaitForEvent mode with power Apply and/or ignition selected for wakeup.
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.

Analog Inputs
The M2M Control CX530 has three analog inputs, which can be configured individually to work
either as voltage or current measurement inputs by 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. 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.

CAN bus port
The CX530 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 CX530 is connected to a "non-existing" network, a 120 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. This resistor can be connected by activating the software jumper in the
user application. Please consult the M2M CONTROL IDE document for the software jumper for a
detailed description.
Be aware that connecting the CX530 to a CAN network can be dangerous. If the CX530 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, the write capability on the CAN bus is disabled. This can be enabled by the jumper
located internal in the device. Please refer to Appendix D for the configuration details.

RS485 is a multi-drop network with a maximum of 32 nodes connected simultaneously to the bus.
The RS485 bus contains an RSA and an RSB signal and a signal ground, which must always be
connected to the common signal ground for all nodes connected to the RS485 bus!
The maximum cable length for the RS485 bus is according to the EIA/TIA-485-A standard max.
1000m @ <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 speeds, it might be necessary
to terminate the transmission line with a 120
1
ohm resistor at each end of the transmission line to
terminate it and avoid signal reflections. If the M2M Control CX530 is used as an endpoint node,
the jumper for the RS485 port can be inserted in order to terminate the RS485 communication lines
with 120Ω. By default, the RS485 communication lines are not terminated with 120 Ω.
Please note: For best performance, protection, and noise immunity, it is advised to use a shielded
cable to connect the device to the RS485 communications bus.
