20 Chapter 5 EIA-232: RJ-45 to DB-25

RJ-11 software handshaking (XON/XOFF) cable

The following 3-wire cable is often sufficient for a terminal, printer or other

DTE device configured for software flow control.

Simple software handshaking terminal/printer cable (RJ-11)

This cable is a 3-wire null modem cable. Transmitted data on one end of

the cable is connected to received data at the other end and vice-versa.

The RJ-11 plug fits into the center of the RJ-45 jack. The male DB-25 end

can be plugged directly into most serial terminals and printers without any

adapters.

An RJ-45 8-pin connector uses the same wiring with the center pins only-

pins 3, 4, 5, and 6. See "RJ connector types" on page 18 for a comparison

of various RJ connector types that work with the Digi 10-pin RJ-45 jack.
