DVP15MC11T Operation Manual
Terminal resistor
As suggested in the CANopen protocol, the two ends of the CANopen communication cable should
connect a terminal resistor of 120Ω (1/4W) respectively in order to match the impedance of the
communication signal and reduce the signal reflection interference in normal signal transmission.
The terminal resistor connected to the start of the cable:
The terminal resistor on the distribution box can be used just by setting the terminal resistor switch
to ON.
The terminal resistor connected to the terminal end of the cable:
A terminal resistor TAP-TR01 is needed for connecting to the other end of the cable.
The model of a terminal resistor: TAP-TR01, resistance value: 120Ω (1/4W) as shown below
