CAN-IB130/230/PCIe104 Manual, V1.0

3.2 Field bus connection

The field bus connections are available with a galvanic isolation as an option.

If the CAN interface board you use dosn't has such a galvanic isolation, CAN

ground and PC ground are on the same potential.

3.2.1 CAN high speed (ISO 11898-2), channel 1-4

All CAN channels available on the CAN interface board do have an interface

according to ISO 11898-2. The pin assignment of the signals (CAN

high

speed, CAN

high speed, GND) is shown in table 3-1 and 3-2.

3.2.2 CAN low speed (ISO 11898-3), channel 1

Some variants of the CAN interface board allow to switch channel 1 via soft-

ware from ISO 11898-2 to ISO 11898-3 (CAN low speed). If your CAN inter-

face board supports low speed CAN, the signals are provided on channel 1

with a pin assignment according to table 3-1 and 3-2.

3.2.3 LIN, channel 2

The LIN interface is only available for the CAN-IB230/PCIe104. If your CAN

interface board supports LIN the signals are provided on channel 2.

The LIN interface can be operated in master and slave mode, selectable via

software. At this, the parallel operation of the LIN and CAN interface is possi-

ble. The pin assignment of the available LIN signals (LIN, VBAT

LIN

, GND) is

shown in table 3-1 and 3-2.

3.2.4 Pin assignment of the 10 pin box header (channel 1-4)

The pin assignment of the box header is shown in table 3-1.
