3.8 CAN
The pin assignment of the CAN connector corresponds to the CiA
recommendation DS 102-1.
With solder bridges on the positions JP22 and JP25 on the bottom
side of the Evaluation Board the ground can be connected to the
connector shield .
On the Evaluation Board the High-speed CAN bus can be
terminated with 2 x 60
Ω
by closing the solder bridges on positions
JP23 and JP24 (both solder bridges must be closed, default: open).
With solder bridges on position JP32 (default: open) a
5-Volt supply
can be routed either to pin 1, pin 9, or to both pins of the CAN
connector. This way devices with a low power consumption
(external transceivers or optocouplers for example) can be directly
supplied via the CAN connector.

A
Low-speed CAN transceiver TJA 1054 can be alternatively
equipped on the Evaluation Board. Additionally following actions
are necessary for according operation:
The solder bridges on positions JP28 and JP29 must be set over
from HS (High-speed) to LS (Low-speed).
The 0-Ohm resistor on the MicroMod (above the CAN
transceiver, on the lower right side of the label “4”) must be
unsoldered.
The Low-speed CAN bus is terminated with 5.6 k
Ω
. For lower
termination resistance additional resistors can be equipped on
positions R2 and R3.
The error condition of the Low-speed CAN transceiver is indicated
by the LED LD26.
