WiringforPeer-to-peerCommunication(YS1700,OptionalCode/A31)
Peer-to-peer communication can be used by user programs in the YS1700 programmable mode. To achieve peer-to-peer com-
munication, the wiring is the same as for “two-wire connection” in Wiring for the Serial Communication Interface (Optional Code
/A31) (p. 55). Communication cannot be accomplished with four-wire connections.
