• The slave station can be connected in a multi-drop configuration.

• Always set a unique address to each slave station.

• Attach terminating resistances (a total of four when connecting a 5-wire

system) to the ends of the communications lines. Use 1/2W or greater
terminating resistances of 150Ω ±5%.

• If connecting three lines, short-circuit terminals (60), (62) and (61), (63).

• Do not short-circuit the RDA to RDB and SDA to SDB terminals.

Doing so may cause the
