n RS-485 Interface
Note: Turn on DIP switch S1 on the bypass controller located at the end of the network. if S1 is missing, then an external 120 ohm resistor must
be placed 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 Termination

The two ends of the P1 network line have to be terminated with a 120 ohm resistor between the TXRX+ and TXRX- signals.
The P1000 Bypass has a built in termination resistor that can be enabled or disabled using DIP switch S1. If a bypass is located
at the end of a network line, enable the termination resistor by by setting DIP switch S1 to the ON position. Disable the
termination resistor 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, then an external 120 ohm resistor must be placed across the TXRX
+ and TXRX- signals if the bypass controller is at the end of a network line.
