RIOW REMOTE MODULES. (CANOPEN PROTOCOL).
Line terminating resistor.
In the CAN bus, it is necessary to use a line terminating resistor to identify which are the
elements that occupy the ends of the bus; i.e. the first and last physical element in the
connection. For the central unit, the terminating resistor is factory installed because the CNC
is always at one end of the bus.
The RIOW series modules do not have a factory-installed line terminating resistor. The RIOW
module mounted at the end of the bus must have a 120 line terminating resistor between
pins CAN_H and CAN_L to avoid signal deflections (rebounds).
