If DIP switch S1 is missing place an external 120 ohmresistor across terminals TXRX+ and TXRX–. All other slave devices must have this DIP switch set to the OFF position (or if S1 is missing,no external resistor is used).u Network TerminationThe two ends of the P1 network line have to be terminated with a 120 ohm resistor between the TXRX+ and TXRX- signals.The Z1000 Bypass has a built in termination resistor that can be enabled or disabled using DIP switch S1. If a bypass is locatedat the end of a network line, enable the termination resistor by setting DIP switch S1 to the ON position. Disable the terminationresistor on all slaves that are not located on the network line end.Note: Some bypass controllers do not have DIP switch S1. If this is the case, place an external 120 ohm resistor across the TXRX+ and TXRX-signals if the bypass controller is at the end of a network line.u Recommended CableTable E.2 APOGEE FLN Cable SpecificationsSpecification DescriptionCable Configuration Twisted Shielded PairGauge 18-20 AWG (Solid or Stranded)Wire Lay 6 twists per footShields 100% foil with drain wireNEC Type UL Type CMPTemperature 60 °C or higherE.2 Connecting to a Network410 YASKAWA ELECTRIC SIEP YAIZ1B 01E YASKAWA AC Drive – Z1000 Bypass Technical Manual
