and then it will attempt to detect a peripheral bus connect at the following
speeds: 9,600 bps, 19,200 bps, 38,400 bps, and then 115,200 bps. If the

(Duplex/Simplex Mode) of the
Mode Setting Switch while the
power is ON.
Setting
Leave OFF when peripheral port is to
be used by a Programming Console
or CX-Programmer (with peripheral
bus setting).
Turn ON when peripheral port is to be
used by other than a Programming
Console or CX-Programmer (periph-
eral bus).
Leave OFF when RS-232C port is to
be used by other than a CX-Program-
mer (peripheral bus), such as a PT or
host computer.
Turn ON when RS-232C port is to be
used by a CX-Programmer (periph-
eral bus).
The status of this DIP switch pin is
reflected in the User DIP Switch Pin
