CAN-CR2xx - Manual, V2.0

Indicators and connections

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 connect-

or at IXXAT (ordering number 1.04.0075.03000).
