### RJ-45 8-Pin Plug Hardware Handshaking (RTS/CTS) Cable

Using an 8-pin plug, the following cable wiring is often sufficient for a terminal, printer, or other DTE device configured for RTS/CTS (hardware) flow control. However, some terminals and printers may have other cable requirements. Consult your terminal or printer manual for this information. For more universal compatibility, use the RJ-45 10-wire terminal/printer cable or a Digi RJ-45 to DB-25 adapter.
