RJ45 8-Pin Plug Hardware Handshaking (DTR) Cable
Using an 8-pin plug, the cable wiring shown in
other DTE devices configured for DTR (hardware) flow control. However, some terminals and
printers may use a signal other than DTR for flow control. In addition, some terminals and
printers may have other cable requirements. Consult your terminal or printer manual for this
information. For universal compatibility, use the RJ-45 10-wire terminal/printer cable or a RJ-45
to DB-25 adapter.
Table B-7
lists the pin-out conenction between the RJ-45 8-pin adapter and the DB25
terminal/printer with DTR handshaking.

RJ-45 8-Pin Plug Hardware Handshaking (RTS/CTS) Cable
Using an 8-pin plug, the cable wiring shown in
other DTE devices 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 RoHS RJ-45 to DB-25 adapter.
