Type 3: To connect Smartio C168H/PCI to a DTE with 3-pin wiring.

If the “Hardware flow control” feature is set to “ON”, you must loop back (or short) the RTS with CTS and DSR with DTR, DCD on MOXA site, indicated in dash-lines of the following diagrams. If the “Hardware flow control” feature is set to “OFF”, you could just leave RTS, CTS, DSR, DTR, DCD open, ignoring the connection indicated in dash-lines.
