Dependingon the type of network, either one or two terminations are necessary. Free topology network segmentrequires only one termination whereas a doubly terminated bus topology requires two.The jumper X5 on the Vacon LonWorks board must be set accordingly. Use 94-ohm terminationresistance when only one termination is needed and 47-ohm for two terminations.Figure 3-7.
