Figure C.3 RS-485 Interface
Note: 1. Set DIP switch S2 to the ON position on the drive located at the end of the network. Set DIP switch S2 to the OFF positions on all other
slave devices.
2. Set H5-07 to 1 when using the RS-485 interface.
u
Network Termination
The two ends of the BACnet network line have to be terminated. The drive has a built in termination resistor that can be enabled
or disabled using DIP switch S2. If a drive is located at the end of a network line, enable the termination resistor by setting
DIP switch S2 to the ON position. Disable the termination resistor on all slaves that are not located at the network line end.
