Figure 1: Block circuit diagram
The CAN-CBX-CPU5202 is a stand-alone controller module with a powerful 400 MHz PowerPC,
512 MB R2-S RAM, 1GB NAN -Flash and RTC with battery backup on-board.
The graphic interface uses an integrated 2 /3 graphics engine with Power VR vector processing
unit.
The CAN-CBX-CPU5202 comes with a 100BASE-TX Ethernet interface that is accessible via an
RJ45 plug in the front. An USB device (e.g. printer, memory stick) can be connected on the front
side USB 2.0 Host interface running with high-speed.
The two CAN interfaces are designed according to ISO11898-2 high-speed layer and support bit
rates up to 1 Mbit/s. One CAN interface is electrically isolated and is accessible via a 5-pole
Combicon-style connector. The other CAN interface (optional electrically isolated) is connected to
the InRailBus for local CBX-I/O expansion.
The power supply and the CAN bus signals can be applied via the InRailBus connector (TBUS-
connector) integrated in the mounting rail or separately via the clamp-connection.
From the InRailBus individual modules can be removed without interrupting the bus signals.
Two serial RS-232 interfaces for terminal and debugging are accessible via an RJ12 connector.

2.4 Installation and Wiring of the Module
2.4.1 Connection of the Power Supply Voltage
The power supply voltage can be connected via the +24V connector for the power supply voltage
(X100) or via InRailBus connector (X101)
Attention:
Please note the safety instructions to requirements on the supply current circuit (see
page 4).
Attention:
When connecting via the InRailBus (connector X101), it is not permissible to feed
through the power supply voltage through the CBX station and to supply it to another
CBX station via the +24V connector. A feed through of the +24 V power supply voltage
can cause damage on the CBX modules!
Figure. 5: CAN-CBX station
Earthing the mounting rail
Note:
Connect the mounting rail to functional earth potential. Please note that the impedance
of the connecting cable has to be kept low.
Functional earth is a current path of low impedance between current circuits and earth, which is
used to increase the interference immunity. It is not intended as protective measure and does not
protect against accidental contact.

Hardware Installation
2.4.2 Installation of the Module using the InRailBus connector
If the CAN bus signals of CAN2 and the power supply voltage shall be fed via the InRailBus,
please proceed as follows:
Figure. 6: Mounting rail with bus connector
1. Position the mounting rail bus connector of the InRailBus (CAN-CBX-TBUS, order no.:
C.3000.01) on the mounting rail and snap it onto the mounting rail using slight pressure. Plug
the bus connectors together to contact the communication and power signals (in parallel with
one). The bus connectors can be plugged together before or after mounting the CAN-CBX
modules. One mounting rail bus connector is included in delivery.
Functional earth must be connected to the mounting rail (see page 11).
2. Place the CAN-CBX module with the IN rail guideway on the top edge of the mounting rail.
Figure. 7: Mounting CAN-CBX modules
3. Swivel the CAN-CBX module onto the mounting rail in pressing the module downwards
according to the arrow as shown in figure 7. The housing is mechanically guided by the IN
rail bus connector.

Hardware Installation
4. When mounting the CAN-CBX module the metal foot catch snaps on the bottom edge of the
mounting rail. Now the module is mounted on the mounting rail and connected to the
InRailBus via the bus connector. Connect the bus connectors and the InRailBus, if not
already done.

Hardware Installation
2.4.2.1 Connecting Power Supply and CAN Signals via CBX-InRailBus
To connect the power supply and the CAN-signals via the InRailBus, a terminal plug (CAN-CBX-
TBUS Connector, order no.: C.3000.02) is needed. The terminal plug is not included in delivery
and must be ordered separately (CAN-CBX-Connection adapter, order no.: C.3000.03).
Figure. 10: Mounting rail with InRailBus and terminal plug
Plug the terminal plug into the socket on the right of the mounting-rail bus connector of the
InRailBus, as described in Figure 10. Then connect the CAN interface and the power supply
voltage via the terminal plug.
Please pay attention to the notes on the connection of the power supply voltage on page 11.

Hardware Installation
2.4.2.2 Connection of CAN1 and CAN2
Note:
iffering from the other CAN-CBX-I/O modules the CAN-CBX-CPU5202 module comes
with two independent CAN interfaces.
CAN net 2 of the CAN-CBX-CPU5202 is connected to the CAN-CBX-I/O modules via InRailBus as
described in the wiring diagram (figure 9).
Note:
It is important to use the terminating resistors in the correct way! See also figure 11.
The InRailBus is terminated via two internal resistors (each 33 Ω) in the CAN-CBX-
CPU5202 module. The bus length of the InRailBus shall not exceed l = 0.3 m.
Figure. 11: Connecting the CAN signals to the CAN-CBX station
2.4.3 Remove the CAN-CBX Module from InRailBus
If the CAN-CBX module is connected to the InRailBus please proceed as follows:
Release the module from the mounting rail in moving the foot catch (see Fig. 8) downwards (e.g.
with a screwdriver). Now the module is detached from the bottom edge of the mounting rail and
can be removed.

Hardware Installation
2.5 Battery
The CAN-CBX-CPU5201 module is equipped with an internal RTC (Real Time Clock). The RTC is
powered by a lithium coin cell.
Battery type: 3V, IEC type: 2032
The battery life is expected to be approximately 2.5 - 3 years.
Note:
The lifetime of the battery strongly depends on environmental influences. Therefore an
regular battery change every 2.5 - 3 years is recommended.
2.5.1 Battery Change
The battery is inside the case of the CAN-CBX-CPU5202 module. For a battery change the case
has to be opened.
Attention:
The battery change may only be carried out by qualified personal! Send the CAN-CBX-
CPU5202 module to esd for the battery change if necessary.
Attention:
Electrostatic discharges (ES ) may cause damage to electronic components. For the
battery change the user may be required to take adequate measures.
