3.3 LED and status indicators
The UniCAN  data logger features two LEDs on
the front and back with the exact same function:
fThe network LED (③) indicates the trans-
mission status.
fThe status LED (④) indicates the measure-
ment, operating and card access status.

Tab. 3-3: Color codes for measurement (status LED)
There is also a -digit, -segment display on the front of the UniCAN (①). This display supplements
the two LEDs and is used for visualization of device status and error codes. The location of a dot (⑤)
determines which display is currently active.
fIf the left-hand dot is lit up, the transmission status is being indicated (network LED).
fIf the right-hand dot is lit up, the measurement status is being indicated (status LED).
The display is automatically switched on for  seconds after the device is restarted or for  seconds
if the status changes. If the display is inactive, pressing the button(②) initiates display of the
measurement status (for  seconds). Pressing the button again switches between the display for
measurement and transmission (and lights the display for another  seconds).
All possible indications and status values are listed in the following.

3.4 Installation
NOTE!
i
Cable shield, housing and ground of the connections are connected directly to the
power supply ground (Power GND, negative pole to ground).
)Incorrect cabling may cause damage to the device.
)When connecting the device, ensure correct polarity and supply voltage.
→ Please also observe chapter 3.6.2 “CAN interface”.
NOTE!
i
Trouble-free functioning and electrical safety can only be ensured if the product is
installed properly.
)Ensure proper installation.
)The device may only be operated within the working environment specified.
→ See also “UniCAN 3” datasheet.
NOTE!
i
Observe EMC regulations.
)The device and its antennas must be kept more than cm away from the human
body during operation.
)For compliance with FCC regulations, the antenna gain may not exceed dB.
i
Information on the current status of device and associated software can be found
in the “readme.txt” file of the CSMuniconf software installation package. The most
current version of CSMuniconf can be found in the download area of the CSM website.
→ See: https://s.csm.de/en-uc
.. Check before connection
)Ensure that the cables required for proper connection are used (connection to power supply is
usually made using the K cable).
)Ensure that polarity and supply voltage are correct.
→ See also chapter 3.6.1 “Power supply and Ethernet”.
)Comply with the specifications for all connected components.
.. Connecting the device
)Attach CAN connections of the device to the CAN bus system.
)Connect device to power supply.
.. Inserting CF card and SIM card
3.4.3.1 Opening the hinged cover
The hinged cover of the device can be opened as follows:
)Press against the hinge lightly from
below (see Fig. -).
 The lock is released, the hinged
cover opens.
)Open the hinged cover fully as
shown in Fig. -.

UniCAN  – Installing the device
Installation Manual  Version . // 
3.4.3.2 Inserting a CF card
)Insert a formatted and configured CF cardinto the card slot.
NOTE!
iData storage on CF cards ensures a high degree of security against data loss. To avoid
potential data loss, the CF card should not be inserted or removed during operation.
3.4.3.3 Inserting a SIM card (model-dependent)
i
Only certain versions of the UniCAN  data logger feature a built-in mobile commu-
nications modem (see Tab. -). A SIM card only needs to be inserted if mobile data
transmission is desired. The UniCAN must also have a corresponding transport
configuration and be connected to a suitable antenna (see chapter ..).
With the UniCAN , the SIM card (in mini-SIM format) is first
inserted into a card holder and then into the card slot. The
card holder is released by pressing the button to the right
of the card slot. We recommend using a pointed object,
such as a pen, for this purpose.
)Insert SIM card into the card holder.
)Push card holder into the slot with the SIM card facing
upward until it snaps into place (seeFig. -).
NOTE!
iWhen inserting the SIM card into a UniCAN , make sure that the card holder is inserted
into the slot with the SIM card facing upward. If the card holder is inserted with the
SIM card facing downward, the card can fall out of the holder and damage the device.
.. Putting device into operation
)Switch on the device or connect it to the power supply.
 The start of measurement is indicated by “on.” on the -segment display and occurs immediately
after switch-on.
 The network module is started approx.  seconds later, indicated by “o.n” on the -segment display.
 Connection establishmentthen begins, indicated by statuses “.” through “.”.
)If none of the LEDs are lit up red, everything is ready and in order. If this is not the case, check the
status values.
→ See chapter 3.3 “LED and status indicators”.
 A configuration can either be transmitted from the PC to a CF card inserted into a card reader or directly to a
CFcard in the data logger over a USB connection.
 A connection is only established if the data logger has a transport configuration involving data transmission
over mobile communications or WLAN.
3.5 Replacing the battery
NOTE!
i
UniCAN  data loggers are equipped with a built-in lithium battery which can be
replaced by CSM if necessary.
)Send the device to CSM for service if the battery is no longer working.

UniCAN data loggers are designed for an operating voltage of  V DC (– ) to  V DC ( ). The
connection to power supply and Ethernet is made using a -pole LEMO0B socket on the back of the
housing (see Fig. -, ⑦“Power supply, Ethernet”).
NOTE!
i
The shield and GND of a signal line, as well as the housing of the data logger, are elec-
trically connected to the power GND of the supply line.
There is a risk of damage from short-circuit current or compensating current.
)Never connect the supply voltage to shield, GND or housing.
)Ensure that shield, GND and housing are held on the same potential.

The digital inputs accept voltage levels
of over . V as a logical “” (UIN-High ,
“high” level) and voltage levels below
 V as logical “0” (UIN-Low , “low” level).
The input voltage may be within the
range of 0 V to 10  above the supply
voltage of the battery (.  UBatt). If the
input voltage is less than .V, the
impedance is M. Otherwise, it is
k. The input voltage levelUIN of
all digital inputs is determined ,
times per second (fSkHz).
A logical “” of the digital output
(UOUT-High , “high” level) corresponds to
an output voltage UOUT-High  UBatt – .V,
with an output voltage of up tomA.
With a logical “0” (UOUT-Low , “low”
level), the digital output is connected
with high resistance (k with

characteristic of UOUT with a logical

influenced by the connected consumer.
All outputs and the signal ground are
