6.2.1.3 Using three SDM-SIO2Rs in a system
6.2.1.4 Using three or more SDM-SIO2Rs in a system
6.2.2 Wiring examples for connecting the SDM-SIO2R
The exact method of wiring the SDM-SIO2R varies with the type of device it is going to exchange
data with. The variables include the type of interface used (RS-232, RS-485, or RS-422), whether
handshaking is used, whether the connection is full or half duplex, and whether termination
resistors are used (RS-485 and RS-422 only).
