the device on the DIN rail. The ground of the CAN bus interface is connected to
earth via a 1 MΩ resistor and a 10 nF capacitor.
For best noise immunity results, the shields of the CAN cables have to be
grounded.
2.3.3 DIN rail bus and TBUS plug
The CAN-CR200 and CAN-CR210/FO have a DIN rail bus. With this interface the
device can be connected to other CAN-CR200 or CAN-CR210/FO devices. Using
this feature you have the possibility to realize a star topology with up to 240 CAN
connections.
For the DIN rail bus so called TBUS plugs are necessary. This plugs were pressed
into the DIN rail. More detailed information can be read in chapter 4.2
The signals of the DIN rail bus are described in Table 2-5

2.4 CAN bus termination
The CAN-Repeater offers the possibility to add bus termination resistors to each
CAN network connected to the device. This feature is realized with a DIP switch
for each CAN channel. For more details please refer to chapter 3.1.
As an accessory a bus termination resistor is available as a feed through connector at IXXAT (ordering number 1.04.0075.03000).

3 Configuration
To operate the CAN-Repeater, no software installation is required.
Before you can use the CAN-Repeater the internal DIP switches S301, S302,
CAN1, CAN2 and CAN3 has to be set according to the CAN network configuration.
In Picture 3-1 the positions of the DIP switches of the CAN-CR200 are shown.
The DIP-switches of CAN-CR210/FO and CAN-CR220 are nearly at the same posi-
tion.

Configuration
3.1 Configuration of the bus termination resistors
For each CAN circuit a bus termination resistor can be activated /deactivated by a
DIP switch. Always both positions should be set to ON / OFF.
CAN1 CAN2 CAN3
Default OFF (deactivated) OFF (deactivated) ON (activated)
Table 3-1 Configuration of the bus termination resistors
The bus termination resistors should be activated if the CAN-Repeater is the first
or the last device in the network. The termination resistor value of the total network should be about 60 Ohm (120 Ohm at both ends of the network).
If the bus termination is not correct, transmission problems could happen.
3.2 Configuration of the baudrate
With DIP switch S301 the baudrate of the CAN network is defined. This setting is
necessary, because the internal logic has to detect dominant-lock states (dominant level on CAN bus exceeds the maximum allowed duration).

Configuration
3.3 Configuration of the lock time
With DIP switch S302 the lock time of the CAN-Repeater is defined. This time is
used to avoid bit errors created by the device itself in a result of the signal propagation delay. Such an error could be a short dominant level inside of a recessive
bit, which could cause bit errors at other CAN nodes (depending on the sampling
point).
The setting of the lock time has to be done according to the baudrate and the
capacitive load of the network.

Table 3-3 Configuration of the lock time
For reference values the following settings can be taken:
- for networks with less than 32 nodes the minimum lock time should
be about 300 ns
- for networks between 32 and 64 nodes a minimum lock time of 500 ns
should be used
- for networks with more the 64 nodes a minimum lock time of 1 µs should be
used, but with this setting the maximum baudrate is limited to 500 kBd.

To operate the CAN-Repeater, no software installation is required.
Before you use the CAN-Repeater following points have to be paid attention:
- configuration of the bus termination
- configuration of the baudrate
- configuration of the lock time
More detailed information to these points can be found in chapter 3.
4.1 Mounting a single CAN-Repeater
Prior to mounting the device it has to be assured, that the device is not
connected to power.
In Picture 4-1 mounting of a CAN-CR220 is shown.

Installation
4.2 Mounting with DIN rail bus support
CAN-CR200 and CAN-CR210/FO support a DIN rail bus extension possibility.
This feature gives you an easy possibility creating a star topology.
ATTENTION: The usage of the DIN rail bus is specific for IXXAT devices. If
another DIN rail bus is used, this one must not be connected to the IXXAT DIN rail bus.
If this is not considered, damages at the connected devices
could happen!
Prior to the connection of a device to the DIN rail, the TBUS plug has to be
mounted on the DIN rail. The orientation of the plug has to adapted to the desired device installation position

Installation
The interconnection of two TBUS plugs can be achieved by mounting the plugs
and afterwards were moved together, as shown in Picture 4-3.
Picture 4-3 Mounting of TBUS plugs
Now the CAN-Repeater CAN-CR200 and/or CAN-CR210/FO can be mounted.
The package of the CAN-CR200 and CAN-CR210/FO has an opening for the TBUS
plug in the area of the DIN rail, see Picture 4-4 . While the devices are attached to
the DIN rail, a correct mounting to the TBUS plug has to be observed. The guide
bar of the plug has to mate into the slot in the package.
