8.5.2 Network polarity and terminationPolarising resistors.Set the two switches to “ON” to activate the two polarising resistors on lines R- and R+.(value = 2200 ohms)Generally, these switches are set to ON for the CCR on the end of the line. For all otherCCRs linked on the same bus, leave them set to OFF.Termination impedance.- Set the two switches to “ON” to insert a 120 ohm resistance in the Jbus line.- This impedance must compulsorily be inserted in the last CCR in the line, and only in thisone.N.B.: do not forget to connect similar impedance on the input line of the master device(robot or micro-computer), if this is placed at the end of the line and does not carry one.RS422/RS485 network polarity and terminationLink number Function Dipswitch1Termination impedanceS5-1S5-2Polarising resistorsS5-3S5-42Termination impedanceS5-5S5-6Polarising resistorsS5-7S5-860 21362 CIRCUIT SELECTOR Installation & Maintenance Page 15 / 32
