Handling Precautions

•Multi-drop connection of slave stations is possible.

•Make sure that different addresses are set for each slave station.

•Provide terminating resistor (total of 4 in the case of a 5-wire system connec-

tion) on both ends of the communications path. Use terminating resistor of 150Ω± 5%, 1/2W min.

•In the case of a 3-wire system connection, short-circuit terminals (57) and (59), (58) and (60) on the DCP301.

•Do not short-circuit the RDA and RDB, or SDA and SDB terminals. Doing so might damage the DCP301.
