Connection
The CANopen specification CiA DS-301 V4.0 requires the cable at both
the start and end of the bus to be terminated with a resistor (120 Ohm,
5% metal film, 1/4 Watt).
The terminating resistor is usually integrated within the connector and
can be activated there.
The cable runs for reliable communication decrease as the transmission
rate is increased. The following values can be used as a guide, but they
should not be regarded as limit values:
Cable data:
Characteristic impedance 100 - 120 Ω

Operating capacitance max. 60 nF/km

Cable resistance (loop) 159.8 Ω/km


Shielded cable
The interface is on the same connec-
tor as the RS232 interface.
The RS232 and CANopen interface
use the same operating earth (GND).
