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).

Typical wiring for the most common configurations are given as examples in the following subsections.
